Question

After creating stored procedure in SQL Server why to replace Create with Alter? What will happen on execution if we do not change it? Is there a better alternate to it other then checking if exist and drop?

Answer 1

Create will fail if table exists. Alter will fail if table does not exist.

If you ask why to use Alter if you can drop and create, a few reasons:

• certain permissions already assigned to the object, you would need to regrant permissions if you drop it
• object is probably used by other objects with schema binding
