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'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.

       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);

COMPATIBILITY

       There is no DROP OPERATOR statement in the SQL standard.
