T-sql: Table valued function

Question

We have a table with a column MyFunction nvarchar() that contains the name of a certain table valued function.

There are different functions so the number of columns can differ per function.

1. Is there a way to call the function as a string?

   For example FunctionA is a function, Set @MyFunction = 'FunctionA' then call MyFunction('x','y')

2. Is there a way to store the results in a tempTable since we don't know the number of columns up front?

Thanks in advance

Answer 1

1. Yes, you can do it using dynamic SQL:

    EXEC sp_executesql N'select * from MyFunction(''x'', ''y'')' 

2. Yes, you can, but you need global temp table:

    EXEC sp_executesql N'select * into ##test from MyFunction(''x'', ''y'')'; select * from ##test; 

Hope this works for you
