DROP OPERATOR

Purpose

Use the DROP OPERATOR statement to drop a user-defined operator.

See Also:

CREATE OPERATOR and ALTER OPERATOR for information on creating and modifying operators
"User-Defined Operators " and Oracle Data Cartridge Developer's Guide for more information on operators in general
ALTER INDEXTYPE for information on dropping an operator of a user-defined indextype

Prerequisites

The operator must be in your schema or you must have the DROP ANY OPERATOR system privilege.

Syntax

drop_operator::=

Semantics

schema

Specify the schema containing the operator. If you omit schema, then Oracle Database assumes the operator is in your own schema.

operator

Specify the name of the operator to be dropped.

FORCE

Specify FORCE to drop the operator even if it is currently being referenced by one or more schema objects, such as indextypes, packages, functions, procedures, and so on, and marks those dependent objects INVALID. Without FORCE, you cannot drop an operator if any schema objects reference it.

Example

Dropping a User-Defined Operator: Example

The following statement drops the operator eq_op:

DROP OPERATOR eq_op;

Because the FORCE clause is not specified, this operation will fail if any of the bindings of this operator are referenced by an indextype.
