DROP OPERATOR

Description

DROP OPERATOR drops an existing operator from the database system. To execute this command you must be the owner of the operator.

Parameters

`IF EXISTS`

Do not throw an error if the operator does not exist. A notice is issued in this case.

*name*

The name (optionally schema-qualified) of an existing operator.

*left_type*

The data type of the operator's left operand; write NONE if the operator has no left operand.

*right_type*

The data type of the operator's right operand.

`CASCADE`

Automatically drop objects that depend on the operator (such as views using it), and in turn all objects that depend on those objects (see Dependency Tracking).

`RESTRICT`

Refuse to drop the operator if any objects depend on it. This is the default.

Examples

Remove the power operator a^b for type integer:

DROP OPERATOR ^ (integer, integer);

Remove the bitwise-complement prefix operator ~b for type bit:

DROP OPERATOR ~ (none, bit);

Remove multiple operators in one command:

DROP OPERATOR ~ (none, bit), ^ (integer, integer);

Compatibility

There is no DROP OPERATOR statement in the SQL standard.
