HI,I am not getting how to use Table valued functions as columns that i need to fetch are not constants rather they are dynamic "' + @cols + '" .
They can be of any number.
If you show the query that returns the values you want to pass into the FUNCTION as the @cols parameter, we might be able to offer you a revision of your scalar-valued UDF as an iTVF and its corresponding call signature.
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
