NAME¶
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 Section 5.14).
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.
