DROP TRANSFORM [ IF EXISTS ] FOR type_name LANGUAGE lang_name [ CASCADE | RESTRICT ]
Description
Description
DROP TRANSFORM removes a previously defined transform.
To be able to drop a transform, you must own the type and the language. These are the same privileges that are required to create a transform.
Parameters
- `IF EXISTS`
Do not throw an error if the transform does not exist. A notice is issued in this case.
- *type_name*
The name of the data type of the transform.
- *lang_name*
The name of the language of the transform.
- `CASCADE`
Automatically drop objects that depend on the transform, and in turn all objects that depend on those objects (see Dependency Tracking).
- `RESTRICT`
Refuse to drop the transform if any objects depend on it. This is the default.
