DROP 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);
