DROP OPERATOR(7)                                          SQL Commands                                          DROP OPERATOR(7)



NAME
       DROP OPERATOR - remove an operator


SYNOPSIS
       DROP OPERATOR [ IF EXISTS ] name ( { lefttype | NONE } , { righttype | 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.

       lefttype
              The data type of the operator's left operand; write NONE if the operator has no left operand.

       righttype
              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.
