If you already know the params, then just use params and have the query
prepared. When using SQLWhereItems in OnPrepareSQL, or rebuilding the SQL
statement any other way, the query has to be prepared everytime, which can
cost you time. I use params when the query doesn't change, but just the
comparison values. And, I use SQLWhereItems in the OnPrepareSQL event when
I want a dynamic WHERE clause. Also, I only rebuild the query if the
result fields have to change, which is rare.
