Databases :: MySQL And Asp Table Adapters - Error When Trying To Use Subquery
Nov 1, 2010
I have been trying to create a sql statement that uses a subquery to join 2 oracle tables to create a strongly typed table adapter. For example:
Select productName, (select categoryName from categories where categories.category_id = products.category_id) as Category from Products
The ASP .Net tutorial I am working through recommends using subqueries instead of joins for the insert, update and delete commands to be automatically generated by Visual Studio 2010. When I click Finish in the table adapter wizard I get the following error (I am using MySQL version 5.1 and the MySQL Data Connector 6.3.5)
Generated SELECT statement.
Error in SELECT clause: expression near 'SELECT'.
Error in SELECT clause: expression near 'FROM'.
Missing FROM clause.
Error in SELECT clause: expression near','.
Unable to parse query text.
im doing an update in web page by pressing a button. At the start some of the update was from a trigger, but i decided to put the hole update statement in the web page as an updatecommand in VB. this is the error Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.The statement has been terminated.and this is the code.
[Code]....
the error is in the updatecommand. And i dont know what is it.

I am working on an ASP.NET C# web application in Visual Web Developer Express 08', with MySql database.
Everything works just fine, except one problem that drives me crazy for few weeks...
My application randomaly (or not) stop responding, or just freezing for couple of minutes.
I am sure that the problem is connected somehow to my connection with MySql db.
In the debug window in VWD I get over and over the line:
"A first chance exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in MySql.Data.dll"
Note that in each page load I call a function that kills all sleeping MySql connections, so I don't really think that my problem is 'too many connections'.
The error isn't constant, and not occures only in one page, it occures in many pages (that contains mysql access code), randomaly.

I'm developing an ASP.NET app with a MySQL backend, using the MySQL Connector Net 6.2.3.

If I hardcode values into the insert statement, it works fine. But when I put the ? placeholder in, it throws the error. Can anyone help me pinpoint the problem or offer a workaround solution?
I have used ASD.NET code using SQL Database for Transaction operation successfully. By changing the Database Code to interface with MYSQL an Error occurs. If I remove the Transaction Code from within the the application, it works OK by displaying the MYSQL data (Read Only) in the layout of the application. I am using Mysql Essential-4.1.22-win32 and MYSQL Connector ODBC-3.51.2. My objective is to EDIT the MYSQL Data.
I have installed MySQL and set up an ODBC driver to point to a database in MySQL. In ASP.NET I have defined a connection string to attach to this MySQL dtabase.
However in ASP.NET connection wizard, although the tables are shown, no colums are shown and when I attempt to run the page which uses this datasource I get an error message about a syntax error near page 1 at 'Select * from [categories]'. how to use an ODBC (MySQL) datasource in ASP.NET?

I'm working on an ecommerce project that is missing 5,000 product pictures.
I am trying to assign all products without pictures into a category located on a mapping table.
I know an insert can be accomplished from one table (or subquery) to another but I only need to find the product IDs and insert them with default values into the category mapping table that has all non-null columns.
The following code is the farthest I can get without help (I'm not strong in SQL), it won't work because my subquery returns many rows while the SQL statement is designed to insert one - I don't know how to handle this...
[Code]....
Any help would be appreciated from those more experienced than I. BTW... there are no known search results for this type of solution - if there is even a solution.
