CREATE/REPLACE AUTHORIZATION SQL Statements | Teradata Vantage - CREATE AUTHORIZATION and REPLACE AUTHORIZATION - Teradata Vantage - Analytics Database

Creates or replaces an authorization object.

An authorization object associates a database user with an OS platform user identification, allowing an external routine to run in secure mode using the context, privileges, and access control granted to the specified OS user. External routines include UDFs, table UDFs, methods, and external SQL procedures.

You specify an authorization in the external security clause of a foreign table or function mapping (see CREATE FOREIGN TABLE or CREATE FUNCTION MAPPING and REPLACE FUNCTION MAPPING) or in the AUTHORIZATION clause of the READ_NOS table operator (see Teradata Vantage™ - SQL Operators and User-Defined Functions, B035-1210).

For information about the CREATE AUTHORIZATION trusted extensions that you use to access remote systems with QueryGrid, see your Teradata QueryGrid documentation.
