  • Cannot Translate to SQL using Select(x => Func(x))

    - by Dan
    I'm slowly learning the ins and outs of LINQtoSQL, but this is confusing me. Here is the statement I have: IQueryable<IEvent> events = (from e in db.getEvents() select e).Select(x => SelectEvent(x, null)); What the SelectEvent does can be explained in this answer here. I am not using the .toList() function as I don't want potentially thousands of records brought into memory. public IEvent SelectEvent(SqlServer.Event ev, EventType? type) { // Create an object which implements IEvent // I don't have the code in front of me, so forgive the lack of code } My question is really for the Select() method. I get the "Cannot translate to SQL" error and the Select() is listed in the error message. Clueless on this one :-/.

  • What's a good Perl OO interface for creating and sending email?

    - by aidan
    I'm looking for a simple (OO?) approach to email creation and sending. Something like $e = Email->new(to => "test <[email protected]>", from => "from <[email protected]>"); $e->plain_text($plain_version); $e->html($html_version); $e->attach_file($some_file_object); I've found Email::MIME::CreateHTML, which looks great in almost every way, except that it does not seem to support file attachments. Also, I'm considering writing these emails to a database and having a cronjob send them at a later date. This means that I would need a $e->as_text() sub to return the entire email, including attachments, as raw text which I could stuff into the db. And so I would then need a way of sending the raw emails - what would be a good way of achieving this? Many thanks

  • What do angle brackets around an eclipse perspective mean?

    - by Karin
    I wrote a new perspective for our Eclipse RCP Project. The perspective worked fine, but because of a malconfiguration I had to revert to an earlier code-version in which this perspective didn't exist yet. The strange thing is it still gets shown in the "open perspective" Dialog. The only difference is, that it is now in angle brackets and appears two times. What do the angle brackets mean? (unresolved title perhaps?) And how can I get rid of these entries? Thanks a lot!

  • How to keep an Hibernate's Session open until the page is rendered

    - by Neuquino
    I'm having the following problem: I'm using Oracle ADF for the view and controller of my app. With OpenSessionInViewFilter, I intercept the request and open an Hibernate's Session, and it is closed as soon as the bean's method finishes. What I need is to keep the Session opened until the page is rendered, because in my JSP y use the lazy attributes of the object i load from the DB. For example: When I enter index.jspx the IndexBean#main() is executed: public class IndexBean{ private DBObject myDBObject; public String main(){ this.myDBObject = this.myDAO.loadObjectFromDB(); return null; } } in index.jspx I have: ... <af:inputText value="#{myDBObject.lazyAttribute}" /> ... I'd like that the Hibernate's Session keeps open until the af:inputText is processed. Is this possible? How? Thanks in advance

  • How to retrieve MYSQL records as an INSERT statement.

    - by Aglystas
    I'm trying come up with the best method of synchronizing particular rows of 2 different database tables. So, for example there's 2 product tables in different databases as such... Origin Database product{ merchant_id, product_id, ... additional fields } Destination Database product{ merchant_id product_id ... additional fields } So, the database schema is the same for both. However I'm looking to select records with a particular merchant_id, remove all records from the destination table that have that merchant_id and replace those records with records from the origin database of the same merchant_id. My first thought was using mysqldump, parsing out the create table statements, and only running the Insert Statements. Seems like a pain though. So I was wondering if there is a better technique to do this. I would think mysql has some method of creating INSERT statements as output from a SELECT statement, so you can define how to insert specific record information into a new db. Any help would be appreciated, thank you much.

  • Flash crash on long JSON load time

    - by MooCow
    I have a Flex program that gets a JSON array from a PHP script. The PHP script doesn't contain just a simple JSON array but it grabs data from Activecollab and do some work on the data before encoding the data. The first test involve a small JSON array that took a short time to encode by PHP. However, when I try to scale up the test, the Flash movie will crash trying to load the JSON data from PHP. There's no code difference between the tests, just the amount of data and amount of time it takes PHP to encode. Am I looking at a memory problem or a time out problem?

  • Multiple Servers with identical services

    - by Jerry Bailey
    I have a dozen servers in different locations all running the same web service application but each going against their own SQL Server DB. I am writing a desktop application that consumes the web services. I want to present the user with a drop down of all servers in the network that are running the same wweb service application. Do I have to add a ServiceReference for each of the servers running the web service app and thereby having as many proxies as there are servers? Or can a define a single instance of the services and dynamically build a list of endpoints to select from a drop down?

  • Ajax Post Request Returns JSON but Deferred Fails

    - by imrane
    I have a cross-domain POST request to http://api.local/user/auth - my API endpoint. I allow Cross Domain requests in my api with CORS. Using Chrome if that makes a difference. I get a valid server JSON response with 200 Status Code but I am using deferreds from a backbone model like so: @model.save() .fail(-> console.log 'sync fail') .success -> console.log 'sync OK' And I consistently get a 'sync fail' instead of the expected 'sync OK' Thoughts?

  • PHP MVC correct usage

    - by Ratt
    What is the correct (recommended method) for passing information to a view in a MVC environment. Currently we use Zend Framework, where we write classes to handle specific things EG a Book class with a save and load method to retrieve info from the DB, which is called from a particular nameAction(). What I would like to know is what is the best way to pass this information to the view, in some cases we do $this-view-book_name = $book-getBookName(); and in other cases we do the following $this-view-book = $book; OR $this-view-books = Book_Manager::getAllBooks(); and then access the object(s) properties in the view. Information on-line suggests we try limit what access a view has to information, i.e pass them only what they need and in some cases people say its ok to pass stuff through as long as nothing is done to that information.

  • Can Windows Mobile Synch Services use a business layer

    - by Andy Kakembo
    We're building a Win Mobile 6 warehouse app which needs to update our server based corporate DB. We've got a C# business layer that sits on our app server and we'd really like our warehouse app to go through this. We also like MS Synch Services. Is there a way to combine the two ie can we use sync services but get them to go through our business layer ? Has anyone done this and got an example I can follow ? Is there a best practice for this kind of scenario ? Thanks, Andy

  • Actionscript not running in nested MovieClips in Swf loaded into AIR app.

    - by Stray
    I'm loading content swfs into an Air App. The swfs are loaded into the non-app sandbox, and any communication is via the parent/child sandbox bridge. The swfs have timeline code. This code executes fine. The swfs also have mcs on the timeline - any code inside these mcs, or any child mcs of these mcs, is ignored. Simple traces do not execute below the top level timeline of the loaded swfs. I have tried naming the child mcs. I have tried exporting them in the library. Neither makes any difference. When I run the swf standalone, I see my diagnostic traces. When I load the swf, I only see the traces for the top level timeline. Air app is v1.5 Any clues? I've been bashing into this brick wall for several hours now...

  • Faking user interaction on CMS

    - by Leocer
    I'm working with a CMS and need to import data to it using typical html forms. The data itself is in csv files with one page per row. Such is the CMS that importing directly to db isn't possible due to the complexity of the design. It's pretty important that i "fake" usual user interaction because the CMS does a lot of background work that's crucial for the import. Basically, for each row in the csv file, I need to copy a csv column to a html textfield, or select a checkbox, or click a certain button. One major issue is mapping the data in the csv to actions in the CMS. So if one column contains the string 'foobar' is really means "set the firstName dropdown widget to 'foobar'". Is there a tool to automate this? I´ve been looking at AutoHotKey, Selendium, Web-Harvester and many other tools but I'm not convinced they are the correct tools. The main problem is being able to interact with the html pages in a easy way.

  • PHP: Do we have any command via which we can delete the contents of an file without opening it.

    - by Rachel
    Is there any way to remove the contents of an file in php, do we have any php command that does that, I know unlink but I do not want to delete the file instead I just want to remove the contents of that file. I have an file which I pass while called a getCurrentDBSnap function, it takes in the file from /home/test/incoming folder and populates currentDB table state into the file using fputcsv and puts back file to /home/test/outgoing. Currently file stays in incoming folder and when I can call the function getCurrentDBSnap it would take the file and override with latest state of DB into it. Q: My question is, is it possible instead of overwriting the file, we can remove the content of file after ever getCurrentDBSnap such that file in incoming folder would be always empty ? Hope it makes sense :)

  • SQL decimal conversion error

    - by jakesankey
    Hey, my app parses numerous txt files in a directory that are almost all formatted identically, then inserts the values into columns of my sql db. However, there are a few files that the app has come across where a value is 'blank' instead of '0.0', so the application fails stating that it cannot convert that value to numeric. Is there a way I could change the following code to say what says AND also add 'IF value is blank, then import 0.0 instead? foreach (SqlParameter parameter in insertCommand.Parameters) { parameter.Value = null; } string[] values = line.Split(new[] { ',' }); for (int i = 0; i < values.Length - 1; i++) { // if (i = "" || i = null) continue; SqlParameter param = insertCommand.Parameters[i]; if (param.DbType == DbType.Decimal) { decimal value; param.Value = decimal.TryParse(values[i], out value) ? value : 0; } else { param.Value = values[i]; } }

  • SQL server virtual memory usage and perofrmance

    - by user365035
    Hello, I have a very large DB used mostly for analytics. The performance overall is very sluggish. I just noticed that when running the query below, the amount of virtual memory used greatly exceed the amount of physical memory available. Currently, phsycial memory is 10GB (10238 bytes) where as the virtual memory returns significantly more 8388607 bytes. That seems really wrong, but I'm at a bit of a loss on how to proceed. USE [master]; GO select cpu_count , hyperthread_ratio , physical_memory_in_bytes / 1048576 as 'mem_MB' , virtual_memory_in_bytes / 1048576 as 'virtual_mem_MB' , max_workers_count , os_error_mode , os_priority_class from sys.dm_os_sys_info

  • Instrumenting Database Access

    - by Whisk
    Jeff mentioned in one of the podcasts that one of the things he always does is put in instrumentation for database calls, so that he can tell what queries are causing slowness etc. This is something I've measured in the past using SQL Profiler, but I'm interested in what strategies other people have used to include this as part of the application. Is it simply a case of including a timer across each database call and logging the result, or is there a 'neater' way of doing it? Maybe there's a framework that does this for you already, or is there a flag I could enable in e.g. Linq-to-SQL that would provide similar functionality. I mainly use c# but would also be interested in seeing methods from different languages, and I'd be more interested in a 'code' way of doing this over a db platform method like SQL Profiler.

  • Troubles with DateTime and PHP 5.2

    - by Nate Wagar
    I'm attempting to use the PHP DateTime class on a server with PHP 5.2.6, with a test server running PHP 5.3. Here is the code: <?php try { $dt = new DateTime('2009-10-08'); $dt->setDate(2009,10,8); print_r($dt); }catch (Exception $e) { echo $e->getMessage(); } On the test server, things work flawlessly, this is what prints: DateTime Object ( [date] => 2009-10-08 00:00:00 [timezone_type] => 3 [timezone] => America/New_York ) On the server I need to use it on, however, this is what prints: DateTime Object ( ) Removing the setDate makes no difference whatsoever. Any ideas why this might be happening? Thanks!

  • Why would a TableAdapter populate a DataSet with "1/1/2000" for an entire timestamp column?

    - by Rob
    I have a TableAdapter filling a DataSet, and for some reason every select query populates my timestamp column with the value 1/1/2000 for every selected row. I first verified that original values are intact on the DB side; for the most part, they are, although it seems a few rows lost their original timestamp because of update queries performed programmatically before the issue was discovered. The DataColumn type is DateType, while the database (Postgres) column type is timestamp. Up until recently, this was all playing very nicely. I noticed the issue in a bound DataGridView control, and verified that this is not related to data binding by utilizing the 'Preview Data' option in the VS DataSet Editor. Usually when I notice unexpected values popping up in my application it's related to a mis-configured property, type conflict, or another silly mistake I've made. So after checking properties and types, and even recreating the TableAdapter from scratch, to say I'm a little baffled is an understatement. Does anyone have any ideas of what I could do to fix the issue and/or diagnose the cause?

  • jquery iterating through newly created elements

    - by jaeyun
    Hi All, I am trying to add new rows in my table, and save them into DB. First, I use .append() to append rows on the table: $("#tablename").append("<tr id='newRow'><td>newly added row</td></tr>"); The appending function works fine. My page displays the correct result. However, I am unable to select them with $("#newRow").each(function () { alert "it never reaches here!"; }); I am guessing it is because the elements are added after the DOM is loaded. Can anyone please tell me how I can iterate through all my newly added elements? Thank you.
