Stored procedure in MS SQL Server 2005

Here I got a scenario: When I press a button in client application (developed in Delphi) a stored procedure is activated. The stored procedure first declares a cursor for a select statement which returns two columns-BankID and BankCategoryID.Then I need to fetch each row inside the cursor into a record and check for the BankCategoryID and return a resultset according to the BankCategoryID like:

CASE WHEN fetched_re开发者_如何学运维cord.BankCategoryID=1  THEN
    SELECT STATEMENT1 WHEN fetched_record.BankCategoryID=2 THEN
    SELECT STATEMENT2 and so on...

and then I return the result set retrieved from any of the above cases to my client application. Is thi possible?

Perhaps you'd want to use an IF as a control statement within your cursor?

WHILE @@FETCH_STATUS = 0
BEGIN
    IF @BankCategoryID=1  
    BEGIN
       SELECT Baz From Bat;
       DECLARE @Spam bit; 
       SELECT @Spam = 0;
    END

    IF @BankCategoryID=2  
    BEGIN
       SELECT Foo FROM Bar;       
    END
  FETCH NEXT FROM MyCursor INTO @BankID, @BankCategory
END

Here's a sample TSQL cursor. You'd be loading your two column values into 2 variables: @BankID and @BankCategoryID. i.e. FETCH NEXT FROM MyCursor INTO @BankID, @BankCategoryID

Aside: I'm wondering if this could be done all without a cursor? In either case, the above should work for you in implementing more TSQL statements in each iteration of your cursor.
