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; 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.
