DROP CAST
Name
DROP CAST -- remove a 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.
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.
