DROP OPERATOR -- remove an operator


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


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



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


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


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


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


Automatically drop objects that depend on the operator.


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


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);


There is no DROP OPERATOR statement in the SQL standard.
