Synopsis

  1. DROP USER MAPPING [ IF EXISTS ] { <username> | USER | CURRENT_USER | PUBLIC }

Description

DROP USER MAPPING removes an existing user mapping from a foreign server. To run this command, the current user must be the owner of the server containing the mapping.

Parameters

IF EXISTS

Do not throw an error if the user mapping does not exist. Greenplum Database issues a notice in this case.

username

User name of the mapping. CURRENT_USER and USER match the name of the current user. PUBLIC is used to match all present and future user names in the system.

servername

Server name of the user mapping.

Examples

Drop the user mapping named bob, server foo if it exists:

Compatibility

DROP SERVER conforms to ISO/IEC 9075-9 (SQL/MED). The IF EXISTS clause is a Greenplum Database extension.
