DROP OPERATOR command - PolarDB

DROP OPERATOR removes an existing operator from the database. You must be the owner of the operator to run this command.

Synopsis

DROP OPERATOR [ IF EXISTS ] name ( { left_type | NONE } , { right_type | NONE } ) [, ...]
    [ CASCADE | RESTRICT ]

Parameter	Description
`IF EXISTS`	Do not throw an error if the operator does not exist. A notice is issued instead.
`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 (such as views), and in turn all objects that depend on those objects.
`RESTRICT`	Refuse to drop the operator if any objects depend on it. This is the default.

Remove the power operator a^b for type integer:

DROP OPERATOR ^ (integer, integer);

Remove the bitwise-complement prefix operator ~b for type bit:

DROP OPERATOR ~ (none, bit);

Remove the right unary factorial operator x! for type bigint:

DROP OPERATOR ! (bigint, none);

Drop multiple operators in a single command:

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