ALTER PACKAGE

Purpose

Packages are defined using PL/SQL. Therefore, this section provides some general information but refers to Oracle Database PL/SQL Language Reference for details of syntax and semantics.

Use the ALTER PACKAGE statement to explicitly recompile a package specification, body, or both. Explicit recompilation eliminates the need for implicit run-time recompilation and prevents associated run-time compilation errors and performance overhead.

Because all objects in a package are stored as a unit, the ALTER PACKAGE statement recompiles all package objects together. You cannot use the ALTER PROCEDURE statement or ALTER FUNCTION statement to recompile individually a procedure or function that is part of a package.

Note:

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

Prerequisites

For you to modify a package, the package must be in your own schema or you must have ALTER ANY PROCEDURE system privilege.

Syntax

alter_package::=

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

Semantics

schema

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

package

Specify the name of the package to be recompiled.

package_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 packages.
