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.
