ALTER LIBRARY

Purpose

The ALTER LIBRARY statement explicitly recompiles a library. Explicit recompilation eliminates the need for implicit run-time recompilation and prevents associated run-time compilation errors and performance overhead.

Note:

This statement does not change the declaration or definition of an existing library. To redeclare or redefine a library, use the "CREATE LIBRARY" with the OR REPLACE clause.

Prerequisites

If the library is in the SYS schema, you must be connected as SYSDBA. Otherwise, the library must be in your own schema or you must have the ALTER ANY LIBRARY system privilege.

(library_compile_clause: See Oracle Database PL/SQL Language Reference for the syntax of this clause.)

Semantics

schema

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

library_name

Specify the name of the library to be recompiled.

library_compile_clause

See Oracle Database PL/SQL Language Reference for the syntax and semantics of this clause and for complete information on creating and compiling libraries.

EDITIONABLE | NONEDITIONABLE

Use these clauses to specify whether the library becomes an editioned or noneditioned object if editioning is later enabled for the schema object type LIBRARY in schema. The default is EDITIONABLE. For information about altering editioned and noneditioned objects, see Oracle Database Development Guide.
