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. Cloudberry Database 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 Cloudberry Database extension.
