Is it possible to create a stored procedure that has parameters which are all optional individually, but at least one of the parameters must be provided?
For example, if I have a procedure that updates a record, I must pass in a record id, and then at least one column to update. The procedure should check to ensure at least one additional parameter/column is provided.
I would do this in my programming language of choice instead of a stored proc. Why? This is the type of logic checking that TSQL is not very good at; the syntax for checking this will be “icky” and it will be slow.
Also, the biggest performance advantage a stored proc gives you is running compiled SQL. In this case, because the SQL needs to be dynamically built, you lose that advantage. Thus, why do it as a stored procedure?
