DROP TYPE

DROP TYPE deletes a user-defined data type. Only the type owner has permission to run this statement.

     
          DROP TYPE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

**Table 1** DROP TYPE parameters
Parameter	Description	Value Range
IF EXISTS	Sends a notice instead of an error if the specified type does not exist.	-
name	Specifies the name of the type to be deleted (schema-qualified).	Specifies an existing domain type.
CASCADE \| RESTRICT	Specifies how to process related data in the dependent object when a delete operation is performed.	CASCADE: Deletes objects (such as columns, functions, and operators) that depend on the type. RESTRICT: Refuses to delete the type if any objects depend on it. This is the default.
