Name
ALTER PROCEDURE
Synopsis
The ALTER
PROCEDURE
statement allows changes to be made to an existing stored procedure.
Depending on the vendor, the kind and degree of change varies widely.
In SQL Server, this statement alters a previously created procedure
(using the CREATE
PROCEDURE
statement) but doesn’t change
permissions or affect dependent stored procedures or triggers.
In Oracle, this command simply recompiles a PL/SQL stored procedure,
but does not allow the code to be changed. Instead, use the Oracle
command CREATE OR REPLACE PROCEDURE to achieve
the same functionality.
