DROP CAST(7)				   SQL Commands 			     DROP CAST(7)

NAME
       DROP CAST - remove a user-defined cast

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

DESCRIPTION
       DROP CAST removes a previously defined cast.

       To  be able to drop a cast, you must own the source or the target data type. These are the
       same privileges that are required to create a 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.

NOTES
       Use CREATE CAST to create user-defined casts.

EXAMPLES
       To drop the cast from type text to type int:

       DROP CAST (text AS int4);

COMPATIBILITY
       The DROP CAST command conforms to SQL99.
