DROP OPERATOR

DROP OPERATOR — remove an operator

Synopsis

DROP OPERATOR [ IF EXISTS ]name ( {left_type | NONE } ,right_type ) [, ...] [ CASCADE | RESTRICT ]

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; writeNONE 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 (seeSection 5.15).

RESTRICT

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

Examples

Remove the power operatora^b for typeinteger:

DROP OPERATOR ^ (integer, integer);

Remove the bitwise-complement prefix operator~b for typebit:

DROP OPERATOR ~ (none, bit);

Remove multiple operators in one command:

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

Compatibility

There is noDROP OPERATOR statement in the SQL standard.
