  • I would like to prevent these entries from being added to the eventlog.

    - by David Smith
    Our client's application EventLog is getting filled up with warnings due to a bug in the Microsoft SQL Server report viewer control, http://support.microsoft.com/kb/973219. They have thousands of users running reports so this is making their eventlog hard to use and they want them removed on a frequent basis. I tried using PowerShell to remove the events, but that does not seem possible. Is there a way to prevent these entries from being written to the event log in the first place? I'm thinking I would like to filter out events where event source="ASP.NET 2.0.50727.0", eventId ="1309" and Message contains "Reserved.ReportViewerWebControl.axd"

  • how I can print WPF treeview items over multiple pages?

    - by RAJKISHOR
    Hello friend, I want to print tree structure showing in WPF treeview control in multiple page. I tried PrintVisual() but it only prints only visible parts. Then I tried FlowDocument and written AddNode(), but its not showing the same result as treeview doimg. Please help me with code. public void AddNodes(int uid, ListItem tSubNode) { string query = "select fullname, id from members where refCode=" + uid + ";"; String memValue; MySqlCommand cmd = new MySqlCommand(query, db.conn); MySqlDataAdapter _DA = new MySqlDataAdapter(cmd); DataTable _DT = new DataTable(); _DA.Fill(_DT); ListOffset += 20; foreach (DataRow _dr in _DT.Rows) { ListItem tNode = new ListItem(); tNode.Margin = new Thickness(ListOffset,0,0,0); memValue = _dr["fullname"].ToString() + " (" + _dr["id"].ToString() + ")"; tNode.Blocks.Add(new Paragraph(new Run(hyp+memValue))); myList.ListItems.Add(tNode); flowDoc.Blocks.Add(myList); _fdrMembers.Document = flowDoc; if (db.HasMembers(Convert.ToInt32(_dr["id"].ToString()))) { AddNodes(Convert.ToInt32(_dr["id"]), tNode); } } ListOffset = 20; } private void button_Click(object sender, RoutedEventArgs e) { ListOffset = 0; myList.ListItems.Clear(); tSuper.Blocks.Clear(); if (db.GetNameByUID(100001) != null) { tSuper.Blocks.Add(new Paragraph(new Run(db.GetNameByUID(100001)))); myList.ListItems.Add(tSuper); AddNodes(100001, tSuper); } MessageBox.Show("Member by ID - "+does.ToString()+", "+dosnt.ToString(), "Error!", MessageBoxButton.OK, MessageBoxImage.Information); }**strong text**

  • What is happening in this T-SQL code?

    - by Ben McCormack
    I'm just starting to learn T-SQL and could use some help in understanding what's going on in a particular block of code. I modified some code in an answer I received in a previous question, and here is the code in question: DECLARE @column_list AS varchar(max) SELECT @column_list = COALESCE(@column_list, ',') + 'SUM(Case When Sku2=' + CONVERT(varchar, Sku2) + ' Then Quantity Else 0 End) As [' + CONVERT(varchar, Sku2) + ' - ' + Convert(varchar,Description) +'],' FROM OrderDetailDeliveryReview Inner Join InvMast on SKU2 = SKU and LocationTypeID=4 GROUP BY Sku2 , Description ORDER BY Sku2 Set @column_list = Left(@column_list,Len(@column_list)-1) Select @column_list ---------------------------------------- 1 row is returned: ,SUM(Case When Sku2=157 Then Quantity Else 0 End) As [157 -..., SUM(Case ... The T-SQL code does exactly what I want, which is to make a single result based on the results of a query, which will then be used in another query. However, I can't figure out how the SELECT @column_list =... statement is putting multiple values into a single string of characters by being inside a SELECT statement. Without the assignment to @column_list, the SELECT statement would simply return multiple rows. How is it that by having the variable within the SELECT statement that the results get "flattened" down into one value? How should I read this T-SQL to properly understand what's going on?

  • Locating memory leak in Apache httpd process, PHP/Doctrine-based application

    - by Sam
    I have a PHP application using these components: Apache 2.2.3-31 on Centos 5.4 PHP 5.2.10 Xdebug 2.0.5 with Remote Debugging enabled APC 3.0.19 Doctrine ORM for PHP 1.2.1 using Query Caching and Results Caching via APC MySQL 5.0.77 using Query Caching I've noticed that when I start up Apache, I eventually end up 10 child processes. As time goes on, each process will grow in memory until each one approaches 10% of available memory, which begins to slow the server to a crawl since together they grow to take up 100% of memory. Here is a snapshot of my top output: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1471 apache 16 0 626m 201m 18m S 0.0 10.2 1:11.02 httpd 1470 apache 16 0 622m 198m 18m S 0.0 10.1 1:14.49 httpd 1469 apache 16 0 619m 197m 18m S 0.0 10.0 1:11.98 httpd 1462 apache 18 0 622m 197m 18m S 0.0 10.0 1:11.27 httpd 1460 apache 15 0 622m 195m 18m S 0.0 10.0 1:12.73 httpd 1459 apache 16 0 618m 191m 18m S 0.0 9.7 1:13.00 httpd 1461 apache 18 0 616m 190m 18m S 0.0 9.7 1:14.09 httpd 1468 apache 18 0 613m 190m 18m S 0.0 9.7 1:12.67 httpd 7919 apache 18 0 116m 75m 15m S 0.0 3.8 0:19.86 httpd 9486 apache 16 0 97.7m 56m 14m S 0.0 2.9 0:13.51 httpd I have no long-running scripts (they all terminate eventually, the longest being maybe 2 minutes long), and I am working under the assumption that once each script terminates, the memory it uses gets deallocated. (Maybe someone can correct me on that). My hunch is that it could be APC, since it stores data between requests, but at the same time, it seems weird that it would store data inside the httpd process. How can I track down which part of my app is causing the memory leak? What tools can I use to see how the memory usage is growing inside the httpd process and what is contributing to it?

  • PHP PDO SQL Server Select statement not replacing question marks

    - by Metropolis
    Awhile ago I wrote a database class which uses PDO in order to connect to SQL Server databases and also to MySQL databases. It has always replaced the question marks fine when using it on the MySQL databases, but for the SQL Server database I had to create a work around which basically replaces the question marks manually. Here is the code for that. if($this->getPDODriver() == 'odbc' && !empty($values_a) && substr_count($query_s, "?") > 0) { $query_s = preg_replace(array_fill(0, substr_count($query_s, "?"), '/\?/'), $values_a, $query_s, 1); $values_a = NULL; } Now, I understand that this completely defeats the purpose of the question marks and PDO, but it has been working fine for me. What I would like to do now though, is find out why the question marks are not getting replaced in the first place, and remove this workaround. If I have a select statement like the following SELECT * FROM database WHERE value = ? That is what the query looks like when I go to prepare it, but when I display the query results, it is a blank array. Just remember, this class is working fine with MySQL, and it is working fine with the work around above. So I know it has something to do with the question marks.

  • Is there any way to optimize this LINQ where clause that searches for multiple keywords on multiple

    - by Daniel T.
    I have a LINQ query that searches for multiple keywords on multiple columns. The intention is that the user can search for multiple keywords and it will search for the keywords on every property in my Media entity. Here is a simplified example: var result = repository.GetAll<Media>().Where(x => x.Title.Contains("Apples") || x.Description.Contains("Apples") || x.Tags.Contains("Apples") || x.Title.Contains("Oranges") || x.Description.Contains("Oranges") || x.Tags.Contains("Oranges") || x.Title.Contains("Pears") || x.Description.Contains("Pears") || x.Tags.Contains("Pears") ); In other words, I want to search for the keywords Apples, Oranges, and Pears on the columns Title, Description, and Tags. The outputted SQL looks like this: SELECT * FROM Media this_ WHERE (((((((( this_.Title like '%Apples%' or this_.Description like '%Apples%') or this_.Tags like '%Apples%') or this_.Title like '%Oranges%') or this_.Description like '%Oranges%') or this_.Tags like '%Oranges%') or this_.Title like '%Pears%') or this_.Description like '%Pears%') or this_.Tags like '%Pears%') Is this the most optimal SQL in this case? If not, how do I rewrite the LINQ query to create the most optimal SQL statement? I'm using SQLite for testing and SQL Server for actual deployment.

  • Why use SQL database?

    - by martinthenext
    I'm not quite sure stackoverflow is a place for such a general question, but let's give it a try. Being exposed to the need of storing application data somewhere, I've always used MySQL or sqlite, just because it's always done like that. As it seems like the whole world is using these databases, most of all software products, frameworks, etc. It is rather hard for a beginning developer like me to ask a question - why? Ok, say we have some object-oriented logic in our application, and objects are related to each other somehow. We need to map this logic to the storage logic, so we need relations between database objects too. This leads us to using relational database and I'm ok with that - to put it simple, our database rows sometimes will need to have references to other tables' rows. But why do use SQL language for interaction with such a database? SQL query is a text message. I can understand this is cool for actually understanding what it does, but isn't it silly to use text table and column names for a part of application that no one ever seen after deploynment? If you had to write a data storage from scratch, you would have never used this kind of solution. Personally, I would have used some 'compiled db query' bytecode, that would be assembled once inside a client application and passed to the database. And it surely would name tables and colons by id numbers, not ascii-strings. In the case of changes in table structure those byte queries could be recompiled according to new db schema, stored in XML or something like that. What are the problems of my idea? Is there any reason for me not to write it myself and to use SQL database instead?

  • php: showing my country based on my IP, mysql optimized

    - by andufo
    I'm downloaded WIPmania's worldip table from http://www.wipmania.com/en/base/ -- the table has 3 fields and around 79k rows: startip // example: 3363110912 endip // example: 3363112063 country // example: AR (Argentina) So, lets suppose i'm in Argentina and my IP address is: 200.117.248.17 1) I use this function to convert my ip to long function ip_address_to_number($ip) { if(!$ip) { return false; } else { $ip = split('\.',$ip); return($ip[0]*16777216 + $ip[1]*65536 + $ip[2]*256 + $ip[3]); } } 2) I search for the proper country code by matching the long converted ip: $sql = 'SELECT * FROM worldip WHERE '.ip_address_to_number($_SERVER['REMOTE_ADDR']).' BETWEEN startip AND endip'; which is equivalent to: SELECT country FROM worldip WHERE 3363174417 BETWEEN startip AND endip (benchmark: Showing rows 0 - 0 (1 total, Query took 0.2109 sec)) Now comes the real question. What if another bunch of argentinian guys also open the website and they all have these ip addresses: 200.117.248.17 200.117.233.10 200.117.241.88 200.117.159.24 Since i'm caching all the sql queries; instead of matching EACH of the ip queries in the database, would it be better (and right) just to match the 2 first sections of the ip by modifying the function like this? function ip_address_to_number($ip) { if(!$ip) { return false; } else { $ip = split('\.',$ip); return($ip[0]*16777216 + $ip[1]*65536); } } (notice that the 3rd and 4th splitted values of the IP have been removed). That way instead of querying these 4 values: 3363174417 3363170570 3363172696 3363151640 ...all i have to query is: 3363110912 (which is 200.117.0.0 converted to long). Is this right? any other ideas to optimize this process? Thanks!

  • custom wordpress page

    - by sharon
    I'd like to implement a custom post retrieval page in wordpress. Basically, I'm using AJAX to call this page that will be passed a post ID and retrieve certain data from that post. Note: please don't mistake this as a template question. I do not want a template for one single page -- I am looking to make this page query multiple different posts based on postID and return certain data from that post. So I tried creating a page <?php $args=array( 'p'=>'77' ); $friends = new WP_Query($args); ?> <?php if ($friends->have_posts()) : the_post(); ?> <?php the_title(); ?> <?php the_content(); ?> <?php else: ?> <p>Sorry, no posts are available.</p> <?php endif; ?> But this does not work since it is not loading in the wp functions to handle the query. Thanks in advance for any help!

  • Ubuntu 13.10: nslookup not automatically appending DNS suffixes

    - by Alex
    When I configure Ubuntu 13.10 server I ran into a problem: Usally (working on 12.10 machines) I add the following information in my /etc/resolv.conf file: nameserver 192.168.2.180 domain our.domain.com Normally, when I then ping a given host , .e.g: ping host01 It would resolve the FQDN to host01.our.domain.com However in ubuntu 13.10 this doesn't seem to be working, it just returns the following: ~# nslookup host01 Server: 192.168.2.180 Address: 192.168.2.180#53 ** server can't find host01: SERVFAIL Which is normaly since the DNS server doesnt respont to a 'host01' request. However if I do the same nslookup on an Ubuntu 12.10 machine it automatically appends the 'our.domain.com' suffix to whatever I throw at it that doens't already have this suffix. Is this a 13.10 bug, or am I doing something wrong?

  • Comparing two date ranges within the same table

    - by Danny Herran
    I have a table with sales per store as follows: SQL> select * from sales; ID ID_STORE DATE TOTAL ---------- -------- ---------- -------------------------------------------------- 1 1 2010-01-01 500.00 2 1 2010-01-02 185.00 3 1 2010-01-03 135.00 4 1 2009-01-01 165.00 5 1 2009-01-02 175.00 6 5 2010-01-01 130.00 7 5 2010-01-02 135.00 8 5 2010-01-03 130.00 9 6 2010-01-01 100.00 10 6 2010-01-02 12.00 11 6 2010-01-03 85.00 12 6 2009-01-01 135.00 13 6 2009-01-02 400.00 14 6 2009-01-07 21.00 15 6 2009-01-08 45.00 16 8 2009-01-09 123.00 17 8 2009-01-10 581.00 17 rows selected. What I need to do is to compare two date ranges within that table. Lets say I need to know the differences in sales between 01 Jan 2009 to 10 Jan 2009 AGAINST 01 Jan 2010 to 10 Jan 2010. I'd like to build a query that returns something like this: ID_STORE_A DATE_A TOTAL_A ID_STORE_B DATE_B TOTAL_B ---------- ---------- --------- ---------- ---------- ------------------- 1 2010-01-01 500.00 1 2009-01-01 165.00 1 2010-01-02 185.00 1 2009-01-02 175.00 1 2010-01-03 135.00 1 NULL NULL 5 2010-01-01 130.00 5 NULL NULL 5 2010-01-02 135.00 5 NULL NULL 5 2010-01-03 130.00 5 NULL NULL 6 2010-01-01 100.00 6 2009-01-01 135.00 6 2010-01-02 12.00 6 2009-01-02 400.00 6 2010-01-03 85.00 6 NULL NULL 6 NULL NULL 6 2009-01-07 21.00 6 NULL NULL 6 2009-01-08 45.00 6 NULL NULL 8 2009-01-09 123.00 6 NULL NULL 8 2009-01-10 581.00 So, even if there are no sales in one range or another, it should just fill the empty space with NULL. So far, I've come up with this quick query, but I the "dates" from sales to sales2 sometimes are different in each row: SELECT sales.*, sales2.* FROM sales LEFT JOIN sales AS sales2 ON (sales.id_store=sales2.id_store) WHERE sales.date >= '2010-01-01' AND sales.date <= '2010-01-10' AND sales2.date >= '2009-01-01' AND sales2.date <= '2009-01-10' ORDER BY sales.id_store ASC, sales.date ASC, sales2.date ASC What am I missing?

  • SSIS - How do I use a resultset as input in a SQL task and get data types right?

    - by thursdaysgeek
    I am trying to merge records from an Oracle database table to my local SQL table. I have a variable for the package that is an Object, called OWell. I have a data flow task that gets the Oracle data as a SQL statment (select well_id, well_name from OWell order by Well_ID), and then a conversion task to convert well_id from a DT_STR of length 15 to a DT_WSTR; and convert well_name from a DT_STR of length 15 to DT_WSTR of length 50. That is then stored in the recordset OWell. The reason for the conversions is the table that I want to add records to has an identity field: SSIS shows well_id as a DT_WSTR of length 15, well_name a DT_WSTR of length 50. I then have a SQL task that connects to the local database and attempts to add records that are not there yet. I've tried various things: using the OWell as a result set and referring to it in my SQL statement. Currently, I have the ResultSet set to None, and the following SQL statment: Insert into WELL (WELL_ID, WELL_NAME) Select OWELL_ID, OWELL_NAME from OWell where OWELL_ID not in (select WELL.WELL_ID from WELL) For Parameter Mapping, I have Paramater 0, called OWell_ID, from my variable User::OWell. Parameter 1, called OWell_Name is from the same variable. Both are set to VARCHAR, although I've also tried NVARCHAR. I do not have a Result set. I am getting the following error: Error: 0xC002F210 at Insert records to FLEDG, Execute SQL Task: Executing the query "Insert into WELL (WELL_ID, WELL_NAME) Select OWELL..." failed with the following error: "An error occurred while extracting the result into a variable of type (DBTYPE_STR)". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. I don't think it's a data type issue, but rather that I somehow am not using the resultset properly. How, exactly, am I supposed to refer to that recordset in my SQL task, so that I can use the two recordset fields and add records that are missing?

  • Using a custom IList obtained through NHibernate

    - by Abu Dhabi
    Hi.I'm trying to write a web page in .NET, using C# and NHibernate 2.1. The pertinent code looks like this: var whatevervar = session.CreateSQLQuery("select thread_topic, post_time, user_display_name, user_signature, user_avatar, post_topic, post_body from THREAD, [USER], POST, THREADPOST where THREADPOST.thread_id=" + id + " and THREADPOST.thread_id=THREAD.thread_id and [USER].user_id=POST.user_id and POST.post_id=THREADPOST.post_id ORDER BY post_time;").List(); (I have tried to use joins in HQL, but then fell back on this query, due to HQL's unreadability.) The problem is that I'm getting a result that is incompatible with a repeater. When I try this: posts.DataSource = whatevervar.; posts.DataBind(); ...I get this: DataBinding: 'System.Object[]' does not contain a property with the name 'user_avatar'. In an earlier project, I used LINQ to SQL for this same purpose, and it looked like so: var whatevervar = from threads in context.THREADs join threadposts in context.THREADPOSTs on threads.thread_id equals threadposts.thread_id join posts1 in context.POSTs on threadposts.post_id equals posts1.post_id join users in context.USERs on posts1.user_id equals users.user_id orderby posts1.post_time where threads.thread_id == int.Parse(id) select new { threads.thread_topic, posts1.post_time, users.user_display_name, users.user_signature, users.user_avatar, posts1.post_body, posts1.post_topic }; That worked, and now I want to do the same with NHibernate. Unfortunately, I don't know how to make the repeater recognize the fields of the result of the query. Thanks in advance!

  • How to create a list of data clickable? asp.net

    - by Roger Filipe
    Hello, I am learning asp.net but I'm finding some problems. My doubt is how to make a list of titles of news contained in a database. And in this list, each of the titles when clicked is redirected to a page where you will be able to view the news in full (Title, Body, Author ..). What I got: - A database containing a table with the news, every news is associated with an identification code (ex: "ID"). - A page where you will make the listing. (Ex: site / listofnews.aspx) - I have a page that uses the method "querystring" to know what is the primarykey the news. (Ex: site/shownews.aspx?ID=12345, where "12345" is the primarykey of the news. Once it knows what is the primarykey of the news in the database, it loads each of the fields of the page (news.aspx) with the news, this part is working ok. - The data is retrieve using the Linq, so I receive a List of "News", the class "News" as ID, Title, Body, Author.. My doubt is how to make the listing clickable. In php I used this method (make a list of html links, in each link the href field is changed so that the tag "id" coincides with the news): //database used is oracle, $stmt is the query, you don´t need to understand how it works. oci_define_by_name($stmt, "ID", $id); oci_define_by_name($stmt, "TITLE", $title); if (!oci_execute($stmt, OCI_DEFAULT)) { $err = oci_error($stmt); trigger_error('Query failed: ' . $err['message'], E_USER_ERROR); } echo '<br />'; while (oci_fetch($stmt)) {<------While there is data from the database , create links $link = '<a href="site/shownews.php?ID='.$id.'" >'.$title.'</a>';<----the shownews.php?ID= $id, creates the link according with the ID echo $link<---Prints the link echo '<br />'; } How do i make the same with asp.net?

    - by Nick
    Lately I cannot select a word (field) with the mouse. When I left click on a field drag the mouse to the end of the field then release the button, the selection (blue shading) disappears. Sometimes after several tries the shading stays and I can delete the field. Up to a week ago everything worked fine. Is this a bug, virus? I am using Windows 7 Also, in Live Mail after I finished reading an item in the Inbox, I click the X in the upper right corner to return to the rest of my mail, but instead it takes me back to the desktop and have to double click the Live Mail again to continue. Again this only happened recently. Things worked OK before and this does not happen regularly.

  • Dynamic Linq Property Converting to Sql

    - by Matthew Hood
    I am trying to understand dynamic linq and expression trees. Very basically trying to do an equals supplying the column and value as strings. Here is what I have so far private IQueryable<tblTest> filterTest(string column, string value) { TestDataContext db = new TestDataContext(); // The IQueryable data to query. IQueryable<tblTest> queryableData = db.tblTests.AsQueryable(); // Compose the expression tree that represents the parameter to the predicate. ParameterExpression pe = Expression.Parameter(typeof(tblTest), "item"); Expression left = Expression.Property(pe, column); Expression right = Expression.Constant(value); Expression e1 = Expression.Equal(left, right); MethodCallExpression whereCallExpression = Expression.Call( typeof(Queryable), "Where", new Type[] { queryableData.ElementType }, queryableData.Expression, Expression.Lambda<Func<tblTest, bool>>(e1, new ParameterExpression[] { pe })); // Create an executable query from the expression tree. IQueryable<tblTest> results = queryableData.Provider.CreateQuery<tblTest>(whereCallExpression); return results; } That works fine for columns in the DB. But fails for properties in my code eg public partial class tblTest { public string name_test { get { return name; } } } Giving an error cannot be that it cannot be converted into SQL. I have tried rewriting the property as a Expression<Func but with no luck, how can I convert simple properties so they can be used with linq in this dynamic way? Many Thanks

  • Not getting response using SOAP and PHP.

    - by Nitish
    I'm using PHP5 and NuSOAP - SOAP Toolkit for PHP. I created the server using the code below: <?php function getStockQuote($symbol) { mysql_connect('localhost','user','pass'); mysql_select_db('test'); $query = "SELECT stock_price FROM stockprices WHERE stock_symbol = '$symbol'"; $result = mysql_query($query); $row = mysql_fetch_assoc($result); echo $row['stock_price']; } $a=require('lib/nusoap.php'); $server = new soap_server(); $server->configureWSDL('stockserver', 'urn:stockquote'); $server->register("getStockQuote", array('symbol' => 'xsd:string'), array('return' => 'xsd:decimal'), 'urn:stockquote', 'urn:stockquote#getStockQuote'); $HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : ''; $server->service($HTTP_RAW_POST_DATA); ?> The client has the following code: <?php require_once('lib/nusoap.php'); $c = new soapclientNusoap('http://localhost/stockserver.php?wsdl'); $stockprice = $c->call('getStockQuote', array('symbol' => 'ABC')); echo "The stock price for 'ABC' is $stockprice."; ?> The database was created using the code below: CREATE TABLE `stockprices` ( `stock_id` INT UNSIGNED NOT NULL AUTO_INCREMENT , `stock_symbol` CHAR( 3 ) NOT NULL , `stock_price` DECIMAL(8,2) NOT NULL , PRIMARY KEY ( `stock_id` ) ); INSERT INTO `stockprices` VALUES (1, 'ABC', '75.00'); INSERT INTO `stockprices` VALUES (2, 'DEF', '45.00'); INSERT INTO `stockprices` VALUES (3, 'GHI', '12.00'); INSERT INTO `stockprices` VALUES (4, 'JKL', '34.00'); When I run the client the result I get is this: The stock price for 'ABC' is . 75.00 is not being printed as the price.

  • How to group data changes by operation with MySQL triggers

    - by Jan-Henk
    I am using triggers in MySQL to log changes to the data. These changes are recorded on a row level. I can now insert an entry in my log table for each row that is changed. However, I also need to record the operation to which the changes belong. For example, a delete operation like "DELETE * FROM table WHERE type=x" can delete multiple rows. With the trigger I can insert an entry for each deleted row into the log table, but I would like to also provide a unique identifier for the operation as a whole, so that the log table looks something like: log_id operation_id tablename fieldname oldvalue newvalue 1 1 table id 1 null 2 1 table type a null 3 1 table id 2 null 4 1 table type a null 5 2 table id 3 null 6 2 table type b null 7 2 table id 4 null 8 2 table type b null Is there a way in MySQL to identify the higher level operation to which the row changes belong? Or is this only possible by means of application level code? In the future it would also be nice to be able to record the transaction to which an operation belongs. Another question is if it is possible to capture the actual SQL query, besides using the query log. I don't think so myself, but maybe I am missing something. It is of course possible to capture these at the application level, but the goal is to keep intrusions to the application level code as minimal as possible. When this is not possible with MySQL, how is this with other database systems? For the current project it is not an option to use something other than MySQL, but it would be nice to know for future projects.

  • OSX: iTunes won't play .ogg files over shared library

    - by Decavolt
    I have an OSX 10.5 box that is sharing its iTunes library and another 10.6 box connecting to that library through iTunes. It works as expected except for ogg files. Those ogg files are visible and selectable in the shared library but will not play through the share on the client machine. If I move the ogg files to the client machine they play locally just fine. They also play locally on the host machine. They just won't play through the iTunes share. Is this a bug or some other known issue? Is there a fix, short of converting all ogg files to mp3?

  • Experience with AMCC 3ware 9650se raid cards? Ours seems dead

    - by antiduh
    We have a 8-port 3ware 9650se raid card for our main disk array. We had to bring the server down for a pending power outage, and when we turned the machine back on, the raid card never started. This card has been in service for a couple years without problems, and was working up until the shutdown. Now, when we turn the machine on, the bios option rom that normally kicks in before the bootloader doesn't show up, none of the drives start, and when the OS tries to access the device, it just times out. The firmware on it has been upgraded in the past, so it's possible we've hit some sort of firmware bug. We're using it in a Silicon Mechanics R272 machine with gentoo for the OS. The OS eventually boots, but alas, without the card. We've ordered a new one, but I'm worried that if we replace the card it won't recognize the existing array. Has anybody performed a card swap before? Any help would be greatly appreciated.

  • SNMP counter issues with cisco RV082

    - by Chance
    Does anyone else poll this router with SNMP? We are using firmware version: 2.0.0.19-tz We are having problems with the traffic counters, some of them appear to be implemented as 16 bit counter instead of 32 bit counters. The reason this is causing problems is that they roll over (at 65,000) to 0 in less than our minute polling cycle, really skewing our metrics. The counter for the Lan (interface 2) seems to be functioning properly, however interfaces 3 and 4 (WAN and DMZ / WAN2) rollover at 65000. Tue May 11 08:38:31 EDT 2010 IF-MIB::ifInOctets.1 = Counter32: 137634 IF-MIB::ifInOctets.2 = Counter32: 1865677943 IF-MIB::ifInOctets.3 = Counter32: 12450 IF-MIB::ifInOctets.4 = Counter32: 49354 Look at counter IF-MIB::ifInOctets.4 5 seconds later: Tue May 11 08:38:36 EDT 2010 IF-MIB::ifInOctets.1 = Counter32: 137634 IF-MIB::ifInOctets.2 = Counter32: 1865836207 IF-MIB::ifInOctets.3 = Counter32: 13167 IF-MIB::ifInOctets.4 = Counter32: 12900 Any suggestions? Seems like a bug to me, however I just wanted to make sure I wasn't crazy.. Thanks!

  • SQLAlchemy DetachedInstanceError with regular attribute (not a relation)

    - by haridsv
    I just started using SQLAlchemy and get a DetachedInstanceError and can't find much information on this anywhere. I am using the instance outside a session, so it is natural that SQLAlchemy is unable to load any relations if they are not already loaded, however, the attribute I am accessing is not a relation, in fact this object has no relations at all. I found solutions such as eager loading, but I can't apply to this because this is not a relation. I even tried "touching" this attribute before closing the session, but it still doesn't prevent the exception. What could be causing this exception for a non-relational property even after it has been successfully accessed once before? Any help in debugging this issue is appreciated. I will meanwhile try to get a reproducible stand-alone scenario and update here. Update: This is the actual exception message with a few stacks: File "/home/hari/bin/lib/python2.6/site-packages/SQLAlchemy-0.6.1-py2.6.egg/sqlalchemy/orm/attributes.py", line 159, in __get__ return self.impl.get(instance_state(instance), instance_dict(instance)) File "/home/hari/bin/lib/python2.6/site-packages/SQLAlchemy-0.6.1-py2.6.egg/sqlalchemy/orm/attributes.py", line 377, in get value = callable_(passive=passive) File "/home/hari/bin/lib/python2.6/site-packages/SQLAlchemy-0.6.1-py2.6.egg/sqlalchemy/orm/state.py", line 280, in __call__ self.manager.deferred_scalar_loader(self, toload) File "/home/hari/bin/lib/python2.6/site-packages/SQLAlchemy-0.6.1-py2.6.egg/sqlalchemy/orm/mapper.py", line 2323, in _load_scalar_attributes (state_str(state))) DetachedInstanceError: Instance <ReportingJob at 0xa41cd8c> is not bound to a Session; attribute refresh operation cannot proceed The partial model looks like this: metadata = MetaData() ModelBase = declarative_base(metadata=metadata) class ReportingJob(ModelBase): __tablename__ = 'reporting_job' job_id = Column(BigInteger, Sequence('job_id_sequence'), primary_key=True) client_id = Column(BigInteger, nullable=True) And the field client_id is what is causing this exception with a usage like the below: Query: jobs = session \ .query(ReportingJob) \ .filter(ReportingJob.job_id == job_id) \ .all() if jobs: # FIXME(Hari): Workaround for the attribute getting lazy-loaded. jobs[0].client_id return jobs[0] This is what triggers the exception later out of the session scope: msg = msg + ", client_id: %s" % job.client_id

  • Using Excel as front end to Access database (with VBA)

    - by Alex
    I am building a small application for a friend and they'd like to be able to use Excel as the front end. (the UI will basically be userforms in Excel). They have a bunch of data in Excel that they would like to be able to query but I do not want to use excel as a database as I don't think it is fit for that purpose and am considering using Access. [BTW, I know Access has its shortcomings but there is zero budget available and Access already on friend's PC] To summarise, I am considering dumping a bunch of data into Access and then using Excel as a front end to query the database and display results in a userform style environment. Questions: How easy is it to link to Access from Excel using ADO / DAO? Is it quite limited in terms of functionality or can I get creative? Do I pay a performance penalty (vs.using forms in Access as the UI)? Assuming that the database will always be updated using ADO / DAO commands from within Excel VBA, does that mean I can have multiple Excel users using that one single Access database and not run into any concurrency issues etc.? Any other things I should be aware of? I have strong Excel VBA skills and think I can overcome Access VBA quite quickly but never really done Excel / Access link before. I could shoehorn the data into Excel and use as a quasi-database but that just seems more pain than it is worth (and not a robust long term solution) Any advice appreciated. Alex
