14. Favourite talk: multiple purpose SP
Problem:
• Google style search on multiple columns
• LastName, FirstName, SIN, Other Identifiers
SP Code:
Select …
From Person
Where (@LastName is null or LastName = @LastName)
And (@FirstName is null or FirstName = @FirstName)
And …
If the first execution is on @LastName then the execution plan is built based on index
on LastName, the execution plan doesn’t work for other searches

15. Favourite talk: multiple purpose SP
Solution:
• Dynamic SQL
• Depends on whether the search is specific
enough
• Use SP_ExecuteSQL if no recompile is required
• Use Exec(@Stmt) if recompile would be better
