DROP USER MAPPING

Removes a user mapping for a foreign server.

Synopsis ​

DROP USER MAPPING [ IF EXISTS ] { <user_name> | USER | CURRENT_USER | PUBLIC } 
    SERVER <server_name>

Description ​

DROP USER MAPPING removes an existing user mapping from a foreign server.

The owner of a foreign server can drop user mappings for that server for any user. Also, a user can drop a user mapping for their own user name if they have been granted the USAGE privilege on the server.

Parameters ​

IF EXISTS ​

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

user_name ​

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.

server_name ​

Server name of the user mapping.

Examples ​

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

DROP USER MAPPING IF EXISTS FOR bob SERVER foo;

Compatibility ​

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