 "NAME"
DROP_OPERATOR - remove an 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\*(Aqs left operand; write
NONE
if the operator has no left operand.




right_type


The data type of the operator\*(Aqs 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);




.\}


Remove multiple operators in one command:


.\}

DROP OPERATOR ~ (none, bit), ! (bigint, none);




.\}

 "COMPATIBILITY"

There is no
DROP OPERATOR
statement in the SQL standard.
