Dynamic WHERE and ORDER BY Without Dynamic SQL
My friend Jeremy (no blog) pointed me to these two useful articles on how to perform dynamic WHERE clauses and ORDER BY clauses without using dynamic SQL. These were written long ago, but I had never thought to use COALESCE in this way. Very cool!
I will post them here so I can find them later.
UPDATE: This technique may not be as performant as hoped for. Marty in the comments noted that he saw table scans in using COALESCE in this way. Jeremy showed me an example that demonstrated that the execution plan changed from an index seek to an index scan when using COALESCE. As always, test, test, test before rolling this out.
