DROP OPERATOR
DROP OPERATOR — remove an operator
Synopsis
DROP OPERATOR [ IF EXISTS ] name ( { left_type | NONE } , { right_type | NONE } ) [, ...] [ 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; write NONE if the operator has no left operand.
right_type : The data type of the operator's right operand; write NONE if the operator has no 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 Section 5.13).
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 left unary bitwise complement operator ~b for type bit:
DROP OPERATOR ~ (none, bit);
Remove the right unary factorial operator x! for type bigint:
DROP OPERATOR ! (bigint, none);
Remove multiple operators in one command:
DROP OPERATOR ~ (none, bit), ! (bigint, none);
Compatibility
There is no DROP OPERATOR statement in the SQL standard.
