DROP OPERATOR
remove an operator
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 ).
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.
