ALTER OPERATOR

Description

Alters the definition of an operator.

Precautions

ALTER OPERATOR changes the definition of an operator. Currently, the only function available is to change the owner of the operator.

To use ALTER OPERATOR, you must be the owner of the operator. To modify the owner, you must also be a direct or indirect member of the new owning role, and that member must have CREATE permission on the operator's schema. (These restrict that the owner cannot be changed by doing anything other than deleting or rebuilding the operator. However, a user with the SYSADMIN permission can change the ownership of any operator in any way.)

Syntax

ALTER OPERATOR name ( { left_type | NONE } , { right_type | NONE } ) OWNER TO new_owner
ALTER OPERATOR name ( { left_type | NONE } , { right_type | NONE } ) SET SCHEMA new_schema

Parameters

• name

  Name of an existing operator.

• left_type

  Data type of the left operand for the operator; if there is no left operand, write NONE.

• right_type

  Data type of the right operand for the operator; if there is no right operand, write NONE.

• new_owner

  New owner of the operator.

• new_schema

  New schema name of the operator.

Examples

Alter a user-defined operator for text a @@ b:

ALTER OPERATOR @@ (text, text) OWNER TO joe;

Compatibility

The SQL standard does not contain the ALTER OPERATOR statement.
