DROP


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.
