DROP CAST()			 SQL Commands			   DROP CAST()

NAME
       DROP CAST - remove a cast

SYNOPSIS
       DROP CAST [ IF EXISTS ] (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
       IF EXISTS
	      Do not throw an error if the cast does not exist.	 A  notice  is
	      issued in this case.

       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
       To drop the cast from type text to type int:

       DROP CAST (text AS int);

COMPATIBILITY
       The DROP CAST command conforms to the SQL standard.
