• SQL Server join and wildcards

  - by Ernst

  I want to get the results of a left join between two tables, with both having a column of the same name, the column on which I join. The following query is seen as valid by the import/export wizard in SQL Server, but it always gives an error. I have some more conditions, so the size wouldn't be too much. We're using SQL Server 2000 iirc and since we're using an externally developed program to interact with the database (except for some information we can't retrieve that way), we can not simply change the column name. SELECT table1.*, table2.* FROM table1 LEFT JOIN table2 ON table1.samename = table2.samename At least, I think the column name is the problem, or am I doing something else wrong?

• Help with a Join in Rails 3

  - by Adam Albrecht

  I have the following models: class Event < ActiveRecord::Base has_many :action_items end class ActionItem < ActiveRecord::Base belongs_to :event belongs_to :action_item_type end class ActionItemType < ActiveRecord::Base has_many :action_items end And what I want to do is, for a given event, find all the action items that have an action item type with a name of "foo" (for example). So I think the SQL would go something like this: SELECT * FROM action_items a INNER JOIN action_item_types t ON a.action_item_type_id = t.id WHERE a.event_id = 1 AND t.name = "foo" Can anybody help me translate this into a nice active record query? (Rails 3 - Arel) Thanks!

• Binding multiple arrays for WHERE IN in PostgreSQL

  - by Alec

  So I want to prepare a query something like: SELECT id FROM users WHERE (branch, cid) IN $1; But I then need to bind a variable length list of arrays like (('a','b'),('c','d')) to it. How do I go about doing this? I've tried using ANY but can't seem to get the syntax right. Cheers, Alec Edit: After some fiddling around, this is valid syntactically: SELECT id FROM users WHERE (branch, cid) = ANY ($1::text[][]); and then binding the string '{{a,b},{c,d}}' to $1 but throws the error "operator does not exist: record = text". Changing 'text' to 'record' then throws "input of anonymous composite types is not implemented". Any ideas?

• Storing millions of URLs in a database for fast pattern matching

  - by Paras Chopra

  I am developing a web analytics kind of system which needs to log referring URL, landing page URL and search keywords for every visitor on the website. What I want to do with this collected data is to allow end-user to query the data such as "Show me all visitors who came from Bing.com searching for phrase that contains 'red shoes'" or "Show me all visitors who landed on URL that contained 'campaign=twitter_ad'", etc. Because this system will be used on many big websites, the amount of data that needs to log will grow really, really fast. So, my question: a) what would be the best strategy for logging so that scaling the system doesn't become a pain; b) how to use that architecture for rapid querying of arbitrary requests? Is there a special method of storing URLs so that querying them gets faster? In addition to MySQL database that I use, I am exploring (and open to) other alternatives better suited for this task.

• Quick MySQLi security question

  - by Benjamin Falk

  I have a quick MySQLi security related question... For example, take a look at this code (gets in put from the user, checks it against the database to see if the username/password combination exist): $input['user'] = htmlentities($_POST['username'], ENT_QUOTES); $input['pass'] = htmlentities($_POST['password'], ENT_QUOTES); // query db if ($stmt = $mysqli->prepare("SELECT * FROM members WHERE username=? AND password = ?")) { $stmt->bind_param("ss", $input['user'], md5($input['pass'] . $config['salt'])); $stmt->execute(); $stmt->store_result(); // check if there is a match in the database for the user/password combination if ($stmt->num_rows > 0) {} } In this case, I am using htmlentities() on the form data, and using a MySQLi prepared statement. Do I still need to be using mysql_real_escape_string()?

• Get records from Access table

  - by chianta

  On Access 2010 I need to use VBA to get the records in a table, process them and put them in a new table. Could you tell me how can I do? Is there a way similar to C # to put everything into a datatable the result of a query? I found an example on how to get the data. http://pastebin.com/bCtg20jp But it always fails on the first statement "ADODB.Recordset". I went to see the included libraries and library that uses ADODB is already included "Microsoft Access 14.0 Object Library". Thanks

• Problem with autocommit in ANT SQL task

  - by Alex Stamper

  I have an SQL script and want to apply it witn ANT task. This script clears out schema, creates new tables and views. The ANT defined task as follows: <sql driver="com.mysql.jdbc.Driver" url="jdbc:mysql://host:3306/smth" userid="smth" password="smth" expandProperties="false" autocommit="true" src="all.sql" > </sql> When this task launches, it shows in log that tables are cleared and created. But when it tries to create first view, it fails with: Failed to execute: CREATE VIEW component... AS SELECT component_raw.id AS MySQLSyntaxErrorException: Table 'component_raw' doesn't exist I have no idea why it fails here. Running this all.sql from MySQL query browser gives no errors. When I launched ANT with -v option, I didn't see any "COMMIT" messages.. Please, help to resolve the problem.

• How do I get the window id and tab number of a Terminal window using AppleScript via the ScriptingBr

  - by Gavin Brock

  I can open a Terminal tab using the following AppleScript: tell application "Terminal" set myTab to do script "exec sleep 1" get myTab end tell This returns a string like: tab 1 of window id 3263 of application "Terminal". This is great, I can see the window id 3263 and tab number 1 (although I don't know how to query myTab to get only these values). In the Cocoa ScriptingBridge, I can do: SBApplication *terminal; SBObject *tab; terminal = [SBApplication applicationWithBundleIdentifier:@"com.apple.terminal"] tab = [terminal doScript:@"exec sleep 1" in:nil] How do I get the window id and tab number from the tab object?

• Cross Domain Post - Losing POST Data

  - by Tomas Beblar

  I have 2 servers, both running R2 / IIS7 / ASP Classic sites (can't get around any of that) Server A is making the follow calls: Dim objXMLHTTP, xml Set xml = Server.CreateObject("Msxml2.ServerXmlHTTP.6.0") xml.Open "POST", templateName, false xml.setRequestHeader "Content-Type", "application/xml" xml.Send variables Where the templateName is the URL of Server B (It's an email template) ... and variables are a name value pair string like a query string password=myPassword&customerEmail=Dear+Bob,.... Server B receives the POST but all the POST data (password=myPassword&customerEmail=Dear+Bob,....) is missing from the POST password = Request.Form("templatePassword") customerEmail = Request.Form("RackAttackCustomerEmail") The above values are all empty. Here's the kicker. This all worked on our old servers (Windows Server 2003, IIS 6) But when we migrated over, this stopped working correctly. My question is: What would cause the POST data to be dropped in IIS 7 when it all worked in IIS 6? I've done about 3 days of research into this trying many different things and nothing has worked. The POST data is just gone.

• PHP - Loop thru recordset and fire event each n rows

  - by Luciano

  I'm looking for the right logic to loop thru a recordset and fire an event each n times. Searching on Google i've found some discussion on similar situations, but it seems that solutions don't fits my needs. Let's say i have a recordset of 22 rows. I want to loop thru each row and launch a function on the 4th, the 8th, the 12th and so on... Using the modulus operator as shown in this answer, if($i % 4 == 0), i get the event fired each 4 rows, but 22 its not a multiple of 4 so the event is fired till the 20th row and then nothing. Maybe i need to make a division counting rows in 'excess'? Since the recordset will be between 50 and 200 rows i think its not necessary run multiple query of 4 rows, am I wrong? Thanks in advance!

• Find the xmlHttpRequest resource in aspx page

  - by DJStroky

  I'm trying to find an xmlHttpRequest or similar resource that I can query directly to obtain an xml file for my own purposes. At this site it is possible to browse a Google Map mashup with markers. Unfortunately it is only possible to view all markers at a small view range, whereas I simply want to obtain all the information at once for the entire state. Using the firebug console in firefox I can enter the following javascript line to obtain the xml that I desire: document.getElementById("stationXML").value I tracked this document element down to an <input> tag, but I can't figure out how that input is set. Thanks in advance for your help!

• What is the effect of running an application with "Unlimited Stack" size

  - by NSA

  Hello All, I have inherited some code that I need to maintain that can be less than stable at times. The previous people are no longer available to query as to why they ran the application in an environment with unlimited stack set, I am curious what the effects of this could be? The application seems to have some unpredictable memory bugs that we cannot find and running the application under valgrind is not an option because it slows the application down so much that we cannot actually run it. So any thoughts on what the effects of this might be are appreciated. Thank you.

• SQL Server (2005) Linked Server Issue

  - by David.Chu.ca

  I have SQL Server 2005 with several linked server defined. One of them is a connection to an Oracle server and another one is an ODBC bridge to another server on a remote machine (ODBC server). Recently I tried to use the linked server to Oracle to update data with two large size tables by using several joints. The update query took too long time and finally there was exception thrown: Update O set value = l.value FROM OracleServer..schema.largesizeTable O Join localLargeSizeTable l on .... The problem is that after the exception, I realized that another linked server to ODBC was not working any more. I had to restart SQL server to get the ODBC linked server back. It looks that the linked server pool could be crashed if any of them failed(not like sandbox in Chrome for each tab and no impact on other tabs or Chrome application at all). I am not sure if my assumption is correct or not. Is this a known issue of SQL server 2005?

• Odd GROUP BY output DB2 - Results not as expected

  - by CallCthulhu

  If I run the following query: select load_cyc_num , crnt_dnlq_age_cde , sum(cc_min_pymt_amt) as min_pymt , sum(ec_tot_bal) as budget , case when ec_tot_bal 0 then 'Y' else 'N' end as budget , case when ac_stat_cde in ('A0P','A1P','ARP','A3P') then 'Y' else 'N' end as arngmnt , sum(sn_close_bal) as st_bal from statements where (sn_close_bal 0 or ec_tot_bal 0) and load_cyc_num in (200911) group by load_cyc_num , crnt_dnlq_age_cde , case when ec_tot_bal 0 then 'Y' else 'N' end , case when ac_stat_cde in ('A0P','A1P','ARP','A3P') then 'Y' else 'N' end then I get the correct "BUDGET" grouping, but not the correct "ARRANGEMENT" grouping, only two rows have a "Y". If I change the order of the case statements in the GROUP BY, then I get the correct grouping (full Y-N breakdown for both columns). Am I missing something obvious?

• MySQL: updating a row and deleting the original in case it becomes a duplicate

  - by Silvio Donnini

  I have a simple table made up of two columns: col_A and col_B. The primary key is defined over both. I need to update some rows and assign to col_A values that may generate duplicates, for example: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 This statement sometimes yields a duplicate key error. I don't want to simply ignore the error with UPDATE IGNORE, because then the rows that generate the error would remain unchanged. Instead, I want them to be deleted when they would conflict with another row after they have been updated I'd like to write something like: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 ON DUPLICATE KEY REPLACE which unfortunately isn't legal in SQL, so I need help finding another way around. Also, I'm using PHP and could consider a hybrid solution (i.e. part query part php code), but keep in mind that I have to perform this updating operation many millions of times. thanks for your attention, Silvio Reminder: UPDATE's syntax has problems with joins with the same table that is being updated

• MySQL, C++: Retrieving auto-increment ID

  - by Thomas Matthews

  I have a table with an auto-incrementing ID. After inserting a new row, I would like to retrieve the new ID. I found an article that used the MySQL function LAST_INSERT_ID(). The article says to create a new query and submit it. I'm using MySQL Connector C++, Windows XP and Vista, and Visual Studio 9. Here are my questions: Is there an API, for the connector, that will fetch the ID out of the record? Does the result set, after an insert/append, contain the new ID? The LAST_INSERT_ID is MySQL specific. Is there an SQL standard method for obtaining the new ID?
