Description

The SECURITY clause in Amazon Redshift stored procedures defines the access control and permissions context under which the procedure executes. This determines whether the procedure uses the privileges of the owner (creator) or the caller (user invoking the procedure).

Grammar Syntax

[ { SECURITY INVOKER | SECURITY DEFINER } ]
