Question

The SQL Server (2000/2005) function gets the table name and the field name as parameters and returns results from a dynamic query within the function. The results should be assigned to a Table variable which will be used further in a stored procedure. How to achieve this?

I am getting error: ‘Only functions and extended stored procedures can be executed from within a function.’

Declare @Data as table (FieldValue varchar(100)) insert into @Data select * from MyFunction ('Person.Address','AddressID')       -- Function Alter function MyFunction (    @TableName varchar(100), @FieldName varchar(100)  ) returns @GetData table (    FieldValue  varchar(100)  ) as begin         Declare @SQL varchar(250)         Set @SQL = 'Select '+@FieldName+ ' from '+ @TableName         Exec sp_executesql @SQL              return end

I’m not sure how this works with functions, but if you have a Stored Procedure that returns a resultset, you can insert that into a table variable using INSERT EXEC statements.

INSERT @TableVariable EXEC spYourProcedure 

As long as the fields match that will work. Otherwise you can use:

INSERT @TableVariable (FieldInSp1, FieldInSp2) EXEC spYourProcedure 

This way you can pass data between stored procedures. See this page on INSERT EXEC Statements for some extra information.
