Functions on columns like that are a common code smell. They will prevent the use of statistics or indexes and will result in full table scans to satisfy the criteria....

You're just showing us parameter sets. We can't tell anything about what's happening inside the stored procedure based on a set of parameters. We need to see the actual SELECT......

A WHILE loop? No, I haven't done that sort of testing at all. It's not something I'd write within T-SQL or expect to perform well, natively compiled or not.

SO, do you mean that even if there are 500 tables in Sybase, we need to manually add source and destination data flow...

Why?
SQL instances don't need to be rebooted daily. Hell, I know of instances that have been running over 6 months.
The SQL server instance is used by...

Without seeing the query plan, the structures, the query... nope, not really.
My tests show a pretty consistent faster behavior for the natively compiled procedures.
