Stored Procedures: OUTPUT vs OUT?（转载）
问
I've seen in BOL under the section regarding Stored Procedures, specifically declaring OUTPUT parameters, where both "OUTPUT" and "OUT" are used.
Is there a difference or is "OUT" an abbreviation for OUTPUT similar to "CREATE Proc" = "CREATE Procedure"?
答
This [ OUT | OUTPUT ] implies that either can be used. The Pipe "|" is an "or" character.
Example F shows both being used CREATE PROCEDURE (Transact-SQL)
