DISASSOCIATE STATISTICS

Purpose

Use the DISASSOCIATE STATISTICS statement to disassociate a statistics type (or default statistics) from columns, standalone functions, packages, types, domain indexes, or indextypes.

Prerequisites

To issue this statement, you must have the appropriate privileges to alter the base object (table, function, package, type, domain index, or indextype).

Syntax

disassociate_statistics::=

Text description of disassociate_statistics

Semantics

FROM COLUMNS | FUNCTIONS | PACKAGES | TYPES | INDEXES | INDEXTYPES

Specify one or more columns, standalone functions, packages, types, domain indexes, or indextypes from which you are disassociating statistics.

If you do not specify schema, Oracle assumes the object is in your own schema.

If you have collected user-defined statistics on the object, the statement fails unless you specify FORCE.

FORCE

Specify FORCE to remove the association regardless of whether any statistics exist for the object using the statistics type. If statistics do exist, the statistics are deleted before the association is deleted.

Example

Disassociating Statistics: Example

This statement disassociates statistics from the pack package in the hr schema:

DISASSOCIATE STATISTICS FROM PACKAGES oe.emp_mgmt;
