DROP TYPE

Removes a data type.

Synopsis

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

Description

DROP TYPE will remove a user-defined data type. Only the owner of a type can remove it.

Parameters

IF EXISTS : Do not throw an error if the type does not exist. A notice is issued in this case.

name : The name (optionally schema-qualified) of the data type to remove.

CASCADE : Automatically drop objects that depend on the type (such as table columns, functions, operators).

RESTRICT : Refuse to drop the type if any objects depend on it. This is the default.

Examples

Remove the data type box;

DROP TYPE box;

Compatibility

This command is similar to the corresponding command in the SQL standard, apart from the IF EXISTS option, which is a LightDB-A Database extension. But note that much of the CREATE TYPE command and the data type extension mechanisms in LightDB-A Database differ from the SQL standard.
