DROP CONVERSION

Name

DROP CONVERSION -- remove a conversion

Synopsis

DROP CONVERSION [ IF EXISTS ] name [ CASCADE | RESTRICT ]

Description

DROP CONVERSION removes a previously defined conversion. To be able to drop a conversion, you must own the conversion.

Parameters

IF EXISTS: Do not throw an error if the conversion does not exist. A notice is issued in this case.
name: The name of the conversion. The conversion name can be schema-qualified.
CASCADE RESTRICT: These key words do not have any effect, since there are no dependencies on conversions.

Examples

To drop the conversion named myname:

DROP CONVERSION myname;

Compatibility

There is no DROP CONVERSION statement in the SQL standard, but a DROP TRANSLATION statement that goes along with the CREATE TRANSLATION statement that is similar to the CREATE CONVERSION statement in PostgreSQL.
