  • T SQL WHERE Clause

    - by johniom
    Hiya Guys, I'm trying to develop some code which pulls latest informtion only. What it is when a user goes into a form there a subtable and everytime they change something it creates a new row in the colum called type12_OriginalNoteID which puts its own unquie number in. Another feild called type12_OriginalNoteID keeps the same number - which keeps track of what the oringal number was before any changes were made. I do have some code which does pull the latest information but it does not pull anything if the user has not made any changes to the form - and thats because the type12_OriginalNoteID is null. The code is as follows ea.type12_NoteID IN (SELECT TOP 1 ea.type12_NoteID FROM UserAssessv1aidsadaptations ea1 WHERE ea.type12_NoteID = ea1.type12_OriginalNoteID ORDER BY ea.type12_UpdatedDate DESC) An example of the data is as follows :- type12_note ID - 12 type12_OriginalNoteID NULL type12_UpdatedDate - 11/03/2010 What would be the solution to show the ifnroamtion if no one has made any changes to the subtable? - adding an if statement to run if type12_OriginalNoteID is null??

  • is jQuery 1.4.2 compatible with Closure Compiler?

    - by Mohammad
    According to the official release statement version 1.4 has been re-written to be compressed with Closure Compiler yet when I use the online version of closure compiler I get 130 warnings. This is the code I use. // ==ClosureCompiler== // @compilation_level ADVANCED_OPTIMIZATIONS // @output_file_name default.js // @code_url http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js // ==/ClosureCompiler== And as far as I know you get the real benefit of Closure Compiler if you include the library with your code also, so it removes the unused functions. Yet my testing show that I can't get any further than compressing the library itself.. What am I doing wrong? Any kind of insight will be much appreciated.

  • How do I maintain coherency between model and view-model in MVVM pattern?

    - by Mike Garrett
    Problem Statement I'm writing a very basic WPF application to alter the contents of a configuration file. The data format is an XML file with a schema. I want to use it as a learning project for MVVM, so I have duly divided the code into Model: C# classes auto-generated from xsd.exe View-Model: View-friendly representation of the Model. View: Xaml and empty code behind I understand how the View-Model can make View-binding a breeze. However, doesn't that leave the View-Model <- Model semantics very awkward? Xsd.exe generates C# classes with arrays for multiple XML elements. However, at the V-VM level you need Observable Collections. Questions: Does this really mean I have to keep two completely different collection types representing the same data in coherence? What are the best practices for maintaining coherence between the Model and the View-Model?

  • C# - Convert Implict Type to ObservableCollection

    - by user70192
    Hello, I have a LINQ statement that returns an implicit type. I need to get this type to be an ObservableCollection in my Silverlight 3 application. The ObservableCollection constructor in Silverlight 3 only provides an empty constructor. Because of this, I cannot directly convert my results to an ObservableCollection. Here is my code: ObservableCollection<MyTasks> visibleTasks = e.Result; var filteredResults = from visibleTask in visibleTasks select visibleTask; filteredResults = filteredResults.Where(p => p.DueDate == DateTime.Today); visibleTasks = filteredResults.ToList(); // This throws a compile time error How can I go from an implicitly typed variable to an observable collection? Thank you

  • add Constraint on database with trigger

    - by Am1rr3zA
    Hi, I have 3 tables (Student, Course, student_course_choose(have field grade)) I defined a view on these 3 tables that get me an Average of the each student. I want to have constraint(with trigger) on these view(or on the table that need it) to limit the average of each student between 13 and 18. I somewhere read that I must use foreach statement(instead of foreach row) on trigger because when I decrease some grade of special student and his/her average become less than 13 they don't give me error (because later I increase grade of another his/her course ). how must I wrote this Trigger? (I want to implement aprh for testing trigger) note:I can write it in SQL server, oracle or Mysql no diff for me.

  • WCF Business logic handling

    - by Raj
    I have a WCF service that supports about 10 contracts, we have been supporting a client with all the business rules specific to this client now we have another client who will be using the exact same contracts (so we cannot change that) they will be calling the service exactly the same way the previous client called now the only way we can differentiate between the two clients is by one of the input parameters. Based on this input parameter we have to use a slightly different business logic – the logic for both the Client will be same 50% of the time the remainder will have different logic (across Business / DAL layers) . I don’t want to use if else statement in each of contract implementation to differentiate and reroute the logic also what if another client comes in. Is there a clean way of handling a situation like this. I am using framework 3.5. Like I said I cannot change any of the contracts (service / data contract ) or the current service calling infrastructure for the new client. Thanks

  • UnknownHostException for server java

    - by nilesh
    I am not able to connect to an remote known server through Java code; the exception while connecting is java.net.NoRouteToHostException: No route to host. But strangely, I am able to connect to same server through ssh. Details: Simple Java client when tries to establish connection with Java standalone server, while conneting the exception occurs at following statement: Socket socket = new Socket(ServerIP ServerPort); The port needed is open on server so that externally request can come in. Again the following is returns false InetAddress.getByName(SERVER_IP).isReachable(1000) The Server is running on Fedora, Java 5. FYI: Java cannot resolve DNS address from AIX: UnknownHostException is almost same to my question, but somehow this is not AIX related; moreover I feel the issue to be more of Network or firewall issue. Please guide me.

  • How can I programatically convert SQL data-types to .Net data-types?

    - by Simon
    Can anyone show me a way of converting SQL Server data-types (varchar for example) to .Net data-types (String for example). I'm assuming that automatic conversion is not possible? I have an 'EntityProperty' object and would like it to have an appropriate 'Type' property (string, decimal, int32 etc), at the moment this property is just a string - 'int32' for example. A little background: I'm using SQL DMO in an internal code generation app to query a database and generate a stored procedure based DAL from the database. Being an internal app I can take quite a few shortcuts and make quite a few assumptions. To get the app working at the moment this data-type conversion is handled by a Select Case statement which just converts the types to strings and generates a set of properties based on these strings but I would prefer a little more flexibility in being able to handle the types (use of TypeOf etc). Anyone worked on something similar? I know EF, nHibernate, Subsonic etc could do all this for me but in this case, for various reasons, I am having to roll my own. :)

  • Problem with connection to MS SQL Server database using SSMS

    - by Charles
    I have a database on line with Godaddy (who uses SQL Server 2005). They provide basic management tools, but tell you that for more advanced tools you can connect directly using SSMS. I followed their instructions to ensure my online database will accept remote connections, and can apparently log in using SSMS with success (after giving my hostname and access data). However: When attempting to expand the "Databases" folder tree, I get the following error: Failed to retrieve data for this request. (Microsoft.SqlServer.Management.Sdk.Sfc) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server& LinkId=20476 ADDITIONAL INFORMATION: An exception occurred while executing a Transact-SQL statement or batch.

  • Deep Null checking, is there a better way?

    - by Mattias Konradsson
    We've all been there, we have some deep property like cake.frosting.berries.loader that we need to check if it's null so there's no exception. The way to do is is to use a short-circuiting if statement if (cake != null && cake.frosting != null && cake.frosting.berries != null) ... This strikes me however as not very elegant, there should perhaps be an easier way to check the entire chain and see if it comes up against a null variable/property. So is it possible using some extension method or would it be a language feature, or is it just a bad idea?

  • Any Way to Further Customize Embedded Google Calendar?

    - by user117737
    I'd like to embed a few Google Calendars for my client's web site. The "Google Embeddable Calendar Helper" provides very few customization options. Updating the hex code for the background color in the generated source only works if you pick one of the ~70 standard Google Calendar bg colors. (I can tweak the "border" selector because at least it's in an actual statement.) A "view-source" on the rendered page shows a CSS file loaded from the iframe, but I obviously can't change anything in there. And I assume I can't force an override of selectors with my own CSS file because I have no way of "injecting" it into the iframe. Does anyone know of a (non-API) way of tweaking the colors, fonts, and other CSS thingies in an embedded Google Calendar? Thanks in advance...

  • Combine query results from one table with the defaults from another

    - by pulegium
    This is a dumbed down version of the real table data, so may look bit silly. Table 1 (users): id INT username TEXT favourite_food TEXT food_pref_id INT Table 2 (food_preferences): id INT food_type TEXT The logic is as follows: Let's say I have this in my food preference table: 1, 'VEGETARIAN' and this in the users table: 1, 'John', NULL, 1 2, 'Pete', 'Curry', 1 In which case John defaults to be a vegetarian, but Pete should show up as a person who enjoys curry. Question, is there any way to combine the query into one select statement, so that it would get the default from the preferences table if the favourite_food column is NULL? I can obviously do this in application logic, but would be nice just to offload this to SQL, if possible. DB is SQLite3...

  • Pushing a variable onto a vector, value at that point in vector changes when the variable does.

    - by David Andrews
    I have a programming problem =) std::vector<char*> Names; if(MyPacket.ID == 3) {Names.push_back(MyPacket.Buffer);} I push the recieved buffer onto a vector like so, but when the buffer changes so does the value of the variable at that point in the vector. So say I sent and pushed a buffer containing 'Simon' onto the vector that would be fine so at point [0] on the vector would be the word Simon. but then when I recieve a new buffer it overwrites position [0] even though the packets ID is different, a breakpoint within the if statement is not reached with this new buffer. I really hope i'm explaining this well enough, I tried asking a friends advice and he pointed me towards this site. Any help appreciated David Andrews

  • GNUPlot: change axis labels

    - by Robert
    Dear Guys, I have used the following statement to get the GNUPlot plot a grah for me: plot "force.dat" using 1:2 title "Detroit" with lines, \ "force.dat" u 1:3 t "US Avergae" w linepoints and the "force.dat" looks like 2005 0 0 2006 104 51 2007 202 101 It draws nice graph for me. However, I don't like the X-axis, because it is labelled as 2005, 2005.5, 2006, 2006.5, 2007 etc.. However, those are year identifiers, I only want the 2005, 2006, 2007 etc., how could I get rid of the 2005.5, 2006.5 etc. labels in my GNUPlot graph? Thank you very much for your ideas.

  • Why connection in Python's DB-API does not have "begin" operation?

    - by newtover
    Working with cursors in mysql-python I used to call "BEGIN;", "COMMIT;", and "ROLLBACK;" explicitly as follows: try: cursor.execute("BEGIN;") # some statements cursor.execute("COMMIT;") except: cursor.execute("ROLLBACK;") then, I found out that the underlying connection object has the corresponding methods: try: cursor.connection.begin() # some statements cursor.connection.commit() except: cursor.connection.rollback() Inspecting the DB-API PEP I found out that it does not mention the begin() method for the connection object, even for the extensions. Mysql-python, by the way, throws the Deprecation Warning, when you use the method. sqlite3.connection, for example, does not have the methd at all. And the question is why there is no such method in the PEP? Is the statement somehow optional, is it enough to invoke commit() instead?

  • getting data problem with MYSQL under linux

    - by aelshereay
    Hi all, Recently I started to use Linux (Ubuntu 9.10) instead of windows. I am working on a java web application with Spring, MYSQL with jpa. However, before to install linux I made a backup file from the database, then installed linux, installed the MYSQL Query Browser and Administrator tools, and using the Admin tool restored the backup file, then got all the tables and made a simple select statement from one of the tables and got result normally and everything seems to work just fine. There a USER table, and there's a namedQuery defined to get a user by userName, the problem is that when I pass a correct userName I still get nothing! I really don't know what is the problem! The application was working perfectly under windows! Please, can anyone help me to solve this problem? Thank you in advance.

  • wonder about some #define tricks

    - by kingkai
    Whlie reading codes of my group project, I come across many DEFINEs, and some of them seems strange. To generalize it, please look at the following 2 examples. Example 1: #define SNPRINTF(dst, fmt, arg...) snprintf(dst, sizeof(dst), fmt, ##arg) what does "##" means in this circumstance? I've tried to delete both of them, and write codes like "char buf[1024]; SNPRINTF(buf,"%s,%s","abcd","efg");" which produced the same result. So "##" seems no use and no harm to me. Example 2: #define CLOSE(fd) do { \ if (-1 != (fd)) { \ close(fd); \ (fd) = -1; \ } \ } while (0) Necessary to stuff the inner code to the do{}while(0) statement? what's the use? Thanks!

  • How does SQL Server treat statements inside stored procedures with respect to transactions?

    - by Sleepless
    Hi All! Say I have a stored procedure consisting of several seperate SELECT, INSERT, UPDATE and DELETE statements. There is no explicit BEGIN TRANS / COMMIT TRANS / ROLLBACK TRANS logic. How will SQL Server handle this stored procedure transaction-wise? Will there be an implicit connection for each statement? Or will there be one transaction for the stored procedure? Also, how could I have found this out on my own using T-SQL and / or SQL Server Management Studio? Thanks!

  • INSERT INTO temporary table from sp_executsql

    - by gotqn
    Generally, I am bulding dynamic SQL statement that is executing using sp_executsql like this: EXEC sp_executesql @TempSQLStatement I need to insert the return result row set in something (table variable or temporary table), but I am getting the following error: Msg 208, Level 16, State 0, Line 1746 Invalid object name '#TempTable'. after executing this: INSERT INTO #TempTable EXEC sp_executesql @TempSQLStatement From what I have read, I believe the issue is caused because I am not specifying the columns of the temporary table, but I am not able to do this because the return columns count varies. I have read that I can use global temporary tables, but I have done this before and wonder is there an other way to do that.

  • Wordpress: Check if there are previous posts before displaying link

    I'm using the following code to display a 'previous posts' link on my Wordpress blog. <nav> <ul> <li><?php previous_posts_link('Newer Entries &raquo;') ?></li> </ul </nav> Problem is, when there ARN'T any previous posts, while the link doesn't display, I still get <nav> <ul> <li><</li> </ul </nav> Printed out. Is there an if() statement I could wrap around it all so it checks if there are any previous posts, and only prints it out if there are?

  • How do I create regex groups for replacement?

    - by resting
    I have this sample string: Image: SGD$45.32 SKU: 3f3f3 dfdfd grg4t BP 6yhf Pack Size: 1000's Color: Green Price: SGD$45.32 SGD$45... I would like to remove all the prices namely: SGD$45.32 Price: SGD$45.32 SGD$45 I have this expression thats supposed to match the 3 groups: $pattern = '/(Price.+\sSGD\$\d+\.\d{2})(SGD\$\d+\.\d{2})(SGD\$\d+)/'; $new_snippet = preg_replace($pattern, '', $snippet);` But apparently its not working. It works if I replace a single group at a time. But, I'd like to know if it possible to replace all possible matching groups with a single statement. Tried preg_match_all($pattern, $snippet, $matches); to show matches based on the above pattern, but no matches are found if I put all 3 groups together.

  • How to delete data in DB efficiently using LinQ to NHibernate (one-shot-delete)

    - by kastanf
    Hello, producing software for customers, mostly using MS SQL but some Oracle, a decision was made to plunge into Nhibernate (and C#). The task is to delete efficiently e.g. 10 000 rows from 100 000 and still stay sticked to ORM. I've tried named queries - link already, IQuery sql = s.GetNamedQuery("native-delete-car").SetString(0, "Kirsten"); sql.ExecuteUpdate(); but the best I have ever found seems to be: using (ITransaction tx = _session.BeginTransaction()) { try { string cmd = "delete from Customer where Id < GetSomeId()"; var count = _session.CreateSQLQuery(cmd).ExecuteUpdate(); ... Since it may not get into dB to get all complete rows before deleting them. My questions are: If there is a better way for this kind of delete. If there is a possibility to get the Where condition for Delete like this: Having a select statement (using LinQ to NHibernate) = which will generate appropriate SQL for DB = we get that Where condition and use it for Delete. Thanks :-)
