== CREATE PROCEDURE Syntax==



<source lang="sql">
The basic syntax for creating a stored procedure looks like this:
CREATE PROCEDURE procedure_name
[ { @parameter data_type }[ OUTPUT ]
] [ ,...n ]
[ WITH
{ RECOMPILE | ENCRYPTION } ]
AS sql_statement [ ...n ] ></source>

== Using WITH RECOMPILE==



<source lang="sql">
You can omit the WITH RECOMPILE option in the CREATE PROC statement and then specify
WITH RECOMPILE when you call the procedure.
