  • Stored Procedure for Multi-Table Insert Error: Cannot Insert the Value Null into Column

    - by SidC
    Good Evening All, I've created the following stored procedure: CREATE PROCEDURE AddQuote -- Add the parameters for the stored procedure here AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; Declare @CompanyName nvarchar(50), @Addr nvarchar(50), @City nvarchar(50), @State nvarchar(2), @Zip nvarchar(5), @NeedDate datetime, @PartNumber float, @Qty int -- Insert statements for procedure here Insert into dbo.Customers (CompanyName, Address, City, State, ZipCode) Values (@CompanyName, @Addr, @City, @State, @Zip) Insert into dbo.Orders (NeedbyDate) Values(@NeedDate) Insert into dbo.OrderDetail (fkPartNumber,Qty) Values (@PartNumber,@Qty) END GO When I execute AddQuote, I receive an error stating: Msg 515, Level 16, State 2, Procedure AddQuote, Line 31 Cannot insert the value NULL into column 'ID', table 'Diel_inventory.dbo.OrderDetail'; column does not allow nulls. INSERT fails. The statement has been terminated. I understand that I've set Qty field to not allow nulls and want to continue doing so. However, are there other syntax changes I should make to ensure that this sproc works correctly? Thanks, Sid

  • Continuously checking database from a Windows service

    - by JonF
    I am making a Windows service which needs to continuously check for database entries that can be added at any time to tell it to execute some code. It is looking to see if it's status is set to pending, and it's execute time entry is than the current time. Is the only way to do this to just run select statements over and over? It might need to execute the code every minute which means I need to run the select statement every minute looking for entries in the database. I'm trying to avoid unneccesary cpu time because I'm probably going to end up paying for cpu cycles on the hosting provider

  • js regex replace multiple words

    - by Raghav
    I need to replace ${conferance name} with ABC, ${conference day} with Monday in the following sentence. Could some one help me with the regex. var text = "<td>${conference name}</td><td>${conference day}</td>" var list = ["${conferance name}", "${conference day}" ] for (var j = 1; j < list.length; j++) { //Extracting the col name var colName = list[j].split("${"); colName = colName.split("}")[0]; //Replacing the col name text = text.replace(new RegExp('\\$\\{' + colName + '\\}', 'g'), "ABC"); } The above code repalces fine if i have ${conference_name}, but it fails when i have a space in between. The list is a dynamic array. And the Replace statements are also dynamic. I just simulated them as objects here for fitting them in the Regex Statement. Thanks in Advance.

  • Insert query results into table in ms access 2010

    - by CodeMed
    I need to transform data from one schema into another in an MS Access database. This involves writing queries to select data from the old schema and then inserting the results of the queries into tables in the new schema. The below is an example of what I am trying to do. The SELECT component of the below works fine, but the INSERT component does not work. Can someone show me how to fix the below so that it effectively inserts the results of the SELECT statement into the destination table? INSERT INTO CompaniesTable (CompanyName) VALUES ( SELECT DISTINCT IIF(a.FIRM_NAME IS NULL, b.SUBACCOUNT_COMPANY_NAME, a.FIRM_NAME) AS CompanyName FROM (SELECT ContactID, FIRM_NAME, SUBACCOUNT_COMPANY_NAME FROM qrySummaryData) AS a LEFT JOIN (SELECT ContactID, FIRM_NAME, SUBACCOUNT_COMPANY_NAME FROM qrySummaryData) AS b ON a.ContactID = b.ContactID ); The definition of the target table (CompaniesTable) is: CompanyID Autonumber CompanyName Text Description Text WebSite Text Email Text TypeNumber Number

  • 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?

  • SqlParameter contructor compiler overload choice

    - by Ash
    When creating a SqlParameter (.NET3.5) or OdbcParameter I often use the SqlParameter(string parameterName, Object value) constructor overload to set the value in one statement. When I tried passing a literal 0 as the value paramter I was initially caught by the C# compiler choosing the (string, OdbcType) overload instead of (string, Object). MSDN actually warns about this gotcha in the remarks section, but the explanation confuses me. Why does the C# compiler decide that a literal 0 parameter should be converted to OdbcType rather than Object? The warning also says to use Convert.ToInt32(0) to force the Object overload to be used. It confusingly says that this converts the 0 to an "Object type". But isn't 0 already an "Object type"? The Types of Literal Values section of this page seems to say literals are always typed and so inherit from System.Object. This behavior doesn't seem very intuitive given my current understanding? Is this something to do with Contra-variance or Co-variance maybe?

  • Does HashMap provide a one to one correspondence?

    - by Roman
    I found the following statement: Map is an object that stores key/volume pairs. Given a key, you can find its value. Keys must be unique, but values may be duplicated. For example I have just one key/value pair (3,4). And now I put a new pair (3,5). It will remove the old pair. Right? But if I put (2,4) instead of (3,4) I will add a new pair of key/value to the HashMap. Right?

  • PHP Extension using libtidy compiles, but does not load

    - by ewokker
    I wrote an extension in C++ that uses libtidy, and it runs perfectly under PHP when I compile PHP --with-tidy. However, it would be nice to have the extension run on a vanilla PHP. When I try to use the extension, I get something like: PHP Warning: PHP Startup: Unable to load dynamic library 'extension.so': undefined symbol: tidyCleanAndRepair in Unknown on line 0 and the extension is not loaded. Obviously, the official tidy extension works fine. I have the relevant libtidy development packages installed on the system, and it compiles+links without a problem. I have tried to look through the code for the tidy extension, but it is a huge mass of macros - copying pieces at random felt like cargo code. Besides linking to the library with PHP_ADD_LIBRARY_WITH_PATH(tidy, $TIDY_LIBDIR, TIDY_SHARED_LIBADD), Is there a PHP extension or C statement that fixes this error? Thanks in advance!!

  • StremReader.ReadToEnd() returning an empty string

    - by axk
    I have a method private static String DecompressAndDecode(byte[] data) { GZipStream decompressor = new GZipStream(new MemoryStream(data), CompressionMode.Decompress); StreamReader decompressed = new StreamReader(decompressor, Encoding.UTF8); String result = decompressed.ReadToEnd(); return result; } I have some GZipped text as input and the result is supposed to be a String representation of this text. The problem is that the method returns an empty string. What is puzzling me is that when I step trough the method in debug mode and reach the return statement the result variable is an empty string but if I create a watch for the decompressed.ReadToEnd() expression it returns me the text. What I would expect at this point is the result variable to contain the text and the decompressed.ReadToEnd() expression evaluating to an empty string. (Reevaluating the decompressed.ReadToEnd() expression returns an empty string as expected). There must be something obvious I'm missing here.

  • 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...

  • Delphi, What do I do about "no GetEnumerator present" error when using a for loop over Excel Interop

    - by Ryan
    Hello, I'm trying to write a Delphi program that will loop through each worksheet in an Excel file and format some cells. I'm receiving an error while trying to use the for-in loop over the Workbook.Worksheets collection, though. The error is specifically: [DCC Error] Office.pas(36): E2431 for-in statement cannot operate on collection type 'Sheets' because 'Sheets' does not contain a member for 'GetEnumerator', or it is inaccessible The line of code this occurs for is: for Worksheet in Workbook.Worksheets do The definition of Worksheet and Workbook is as follows: var ExcelApp: ExcelApplication; var Workbook: ExcelWorkbook; var Worksheet: ExcelWorksheet; I'm porting this code to Delphi from C#, in which it works. Does anyone know why I'd be getting this GetEnumerator error? I'm using the Office 2007 Excel Interop file and Embarcadero® Delphi® 2010 Version 14.0.3593.25826. Thanks in advance.

  • 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.

  • SQL: ATER COLUMN to shorter CHAR(n) type

    - by Rising Star
    I'm working with MS SQL SERVER 2003. I want to change a column in one of my tables to have fewer characters in the entries. This is identical to this question: http://stackoverflow.com/questions/2281336/altering-a-table-column-to-accept-more-characters except for the fact that I want fewer characters instead of more. I have a column in one of my tables that holds nine-digit entries. A developer previously working on the table mistakenly set the column to hold ten-digit entries. I need to change the type from CHAR(10) to CHAR(9). Following the instructions from the discussion linked above, I wrote the statement ALTER TABLE [MY_TABLE] ALTER COLUMN [MY_COLUMN] CHAR(9); This returns the error message "String or binary data would be truncated". I see that my nine-digit strings have a space appended to make them ten digits. How do I tell SQL Server to discard the extra space and convert my column to a CHAR(9) type?

  • SQL Server last called stored procedures with parameters

    - by Teoman shipahi
    I am using ASP.NET environment. Is it possible to track last N number of stored procedures called with parameters info? I see in this article "Recently executed stored procedures"; http://sqlfool.com/2009/08/find-recently-executed-stored-procedures/ But I need input parameters also. If not what can be the best way to track it? For example, adding an insert statement to a information table for every single procedure beginning? Or is there any better solution for this?

  • 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.

  • Return an empty IEnumerator

    - by Rekreativc
    Hello! I have an interface that, among other things, implements a "public IEnumerator GetEnumerator()" method, so I can use the interface in a foreach statement. I implement this interface in several classes and in one of them, I want to return an empty IEnumerator. Right now I do this the following way: public IEnumerator GetEnumerator() { ArrayList arr = new ArrayList(); return arr.GetEnumerator(); } However I consider this an ugly hack, and I can't help but think that there is a better way of returning an empty IEnumerator. Is there?

  • Why my custom CStatic derived control does not receive WM_SIZE message?

    - by Michael P
    Hello everyone! I'm currently developing a custom control that derives from CStatic MFC class (Smart Device C++ project). I have created the control class using VC++ MFC class wizard, selecting CStatic class as its base class. I have used Class View to add OnSize event handler for my control class (I have selected WM_SIZE message from messages list), and new OnSize method has been created by Visual Studio along with ON_WM_SIZE() statement between BEGIN_MESSAGE_MAP(...) and END_MESSAGE_MAP(). The problem is that my control does not receive WM_SIZE thus OnSize method is never called - I used MoveWindow to change size of my control - its size changes as I have seen on dialog window but WM_SIZE message is never being sent. When I send WM_SIZE through SendMessage or PostMessage function - the control OnSize method is called normally. What do I wrong? I've read MSDN docs about CStatic control and there is no information that WM_SIZE message is never sent to a static control window. Sorry for my bad English.

  • Integrating a C project in the iPhone SDK

    - by iPhoneARguy
    Hello, This is my first time doing this sort of project so apologies if the question is silly. I've got a question about using a C project with a project in the iPhone SDK. I've dragged and dropped the C project into the iPhone project in Xcode (so it appears in the screenshot below). sjeng.h is a file inside GameEngine.xcodeproj, but when I try to include the header file, I not only receive an error, but the file it is looking for seems to be capitalized whereas the import statement is not. (I would post a screenshot but this is my first time doing something on stack overflow and I need more reputation points. The URL of the screenshot is here: http://imgur.com/AdrGL.png) Does anyone know what the problem might be? Thanks!

  • setting value to the instance of primitive types

    - by Samreen
    I have a function which performs some operation i.e. fetches some data from database. The generic it takes is primitive type always i.e. int, char, bool, string etc. I can easily create its instance. But I can't set the value that I have fetched from database to this instance. public T PerformOperation<T>() { object instance = (T)Activator.CreateInstance(typeof(T)); object result=FetchData(); instance = (T)result; //It gives error on this statement } The function is called as: int result = PerformOperation<int>(); Is there some way of casting the object Type to any generic type which is always primitive?

  • Safe HttpContext.Current.Cache Usage

    - by Burak SARICA
    Hello there, I use Cache in a web service method like this : var pblDataList = (List<blabla>)HttpContext.Current.Cache.Get("pblDataList"); if (pblDataList == null) { var PBLData = dc.ExecuteQuery<blabla>( @"SELECT blabla"); pblDataList = PBLData.ToList(); HttpContext.Current.Cache.Add("pblDataList", pblDataList, null, DateTime.Now.Add(new TimeSpan(0, 0, 15)), Cache.NoSlidingExpiration, CacheItemPriority.Normal, null); } I wonder is it thread safe? I mean the method is called by multiple requesters And more then one requester may hit the second line at the same time while the cache is empty. So all of these requesters will retrieve the data and add to cache. The query takes 5-8 seconds. May a surrounding lock statement around this code prevent that action? (I know multiple queries will not cause error but i want to be sure running just one query.)

  • Deleting orphans with JPA

    - by homaxto
    I have a one-to-one relation where I use CascadeType.PERSIST. This has over time build up a huge amount of child records that has not been deleted, to such an extend that it is reflected in the performance. Now I wish to add some code that cleans up the database removing all the child records that are not referenced by a parent. At the moment we are talking 400K+ records, at I need to run the code on all customer installations just to be sure they do not run into the same problem. I think the best solution would be to run a named query (because we support two databases) that deletes the necessary records, and this is where I get into problems, because how should I write it in JPQL? The result I want can be defined like the following sql statement, which unfortunaltely does not run on MySQL. DELETE FROM child c1 WHERE c1.pk NOT IN (SELECT DISTINCT p.pk FROM child c2 JOIN parent p ON p.child = c2.pk);
