Question

I have a UDF that queries data out of a table. The table, however, needs to be definable as a parameter. For example I can’t have:

Select * From [dbo].[TableA]

I need something like:

Select * From [dbo].[@TableName]

The above line doesn’t work, and also the UDF prohibits me from setting the query as a string and calling exec(). I can do this in a procedure, but I can’t call the procedure from the UDF either.

Does anyone know how I can accomplish this within the UDF without having some kind of massive switch statement?

This can’t be done, dynamic SQL is not supported in functions.
