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.
