an input value. You use the result of that function in a stored
procedure to select rows from some table and produce a result
from that data. The result of the stored procedure is used to
qualify rows in tableA.
That query that has more than 50 conditions in the where clause.
I'm really impressed - in my several years of database programming,
I don't think I've gone beyond 10 conditions, and that only when I
need to compare nulls. Without knowing anything about your application,
I wonder if there may not be some other way to approach the problem.
Have you considered using a view to encapsulate all this?
We have answers.
