    SYNOPSIS

    DROP OPERATOR 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

    name

    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);
