DROP CAST

Name

DROP CAST -- remove a cast

Synopsis

DROP CAST (
sourcetype
 AS 
targettype
) [ CASCADE | RESTRICT ]

Description

DROP CAST removes a previously defined cast.

Parameters

sourcetype

The name of the source data type of the cast.

targettype

The name of the target data type of the cast.

CASCADE
RESTRICT

These key words do not have any effect, since there are no dependencies on casts.

Examples

DROP CAST (text AS int);

Compatibility
