1 Introduction to Oracle Supplied PL/SQL Packages & Types

Oracle supplies many PL/SQL packages with the Oracle server to extend database functionality and provide PL/SQL access to SQL features. You can use the supplied packages when creating your applications or for ideas in creating your own stored procedures.

This manual covers the packages provided with the Oracle database server. Packages supplied with other products, such as Oracle Developer or the Oracle Application Server, are not covered.

Note that not every package or type described in this manual or elsewhere in the Oracle Database Documentation Library is installed by default. In such cases, the documentation states this and explains how to install the object. Run this query as a suitably privileged user:

SELECT DISTINCT Owner, Object_Type, Object_Name FROM DBA_Objects_AE
     WHERE Owner IN (
       'SYS', 'OUTLN', 'SYSTEM', 'CTXSYS', 'DBSNMP',
       'LOGSTDBY_ADMINISTRATOR', 'ORDSYS',
       'ORDPLUGINS', 'OEM_MONITOR', 'MDSYS', 'LBACSYS', 
       'DMSYS', 'WMSYS', 'OLAPDBA', 'OLAPSVR', 'OLAP_USER',
       'OLAPSYS', 'EXFSYS', 'SYSMAN', 'MDDATA',
       'SI_INFORMTN_SCHEMA', 'XDB', 'ODM')
     AND Object_Type IN ('PACKAGE', 'TYPE')
     ORDER BY Owner, Object_Type, Object_Name

This lists every Oracle-supplied package and type that is currently installed in the database. Note that it lists a number of objects not mentioned in the Oracle Database Documentation Library. This is deliberate. Some of the Oracle-supplied packages and types are intended to be used only by other Oracle-supplied components. Any package or type that is not described in the Oracle Database Documentation Library is not supported for direct customer use.

This chapter contains the following topics:

Package Overview

A package is an encapsulated collection of related program objects stored together in the database. Program objects are procedures, functions, variables, constants, cursors, and exceptions.

Package Components

PL/SQL packages have two parts: the specification and the body, although sometimes the body is unnecessary. The specification is the interface to your application; it declares the types, variables, constants, exceptions, cursors, and subprograms available for use. The body fully defines cursors and subprograms, and so implements the specification.

Unlike subprograms, packages cannot be called, parameterized, or nested. However, the formats of a package and a subprogram are similar:

CREATE PACKAGE name AS  -- specification (visible part)
   -- public type and item declarations
   -- subprogram specifications
END [name];

CREATE PACKAGE BODY name AS  -- body (hidden part)
   -- private type and item declarations
   -- subprogram bodies
[BEGIN
   -- initialization statements]
END [name];

The specification holds public declarations that are visible to your application. The body holds implementation details and private declarations that are hidden from your application. You can debug, enhance, or replace a package body without changing the specification. You can change a package body without recompiling calling programs because the implementation details in the body are hidden from your application.

Using Oracle Supplied Packages

Most Oracle supplied packages are automatically installed when the database is created. Certain packages are not installed automatically. Special installation instructions for these packages are documented in the individual chapters.

To call a PL/SQL function from SQL, you must either own the function or have EXECUTE privileges on the function. To select from a view defined with a PL/SQL function, you must have SELECT privileges on the view. No separate EXECUTE privileges are needed to select from the view. Instructions on special requirements for packages are documented in the individual chapters.

Creating New Packages

To create packages and store them permanently in an Oracle database, use the CREATE PACKAGE and CREATE PACKAGE BODY statements. You can execute these statements interactively from SQL*Plus or Enterprise Manager.

To create a new package, do the following:

Create the package specification with the CREATE PACKAGE statement.

You can declare program objects in the package specification. Such objects are called public objects. Public objects can be referenced outside the package, as well as by other objects in the package.

Note:
It is often more convenient to add the OR REPLACE clause in the CREATE PACKAGE statement. But note that CREATE PACKAGE warns you if you are about to overwrite an existing package with the same name while CREATE OR REPLACE just overwrites it with no warning.
Create the package body with the CREATE PACKAGE BODY statement.

You can declare and define program objects in the package body.
- You must define public objects declared in the package specification.
- You can declare and define additional package objects, called private objects. Private objects are declared in the package body rather than in the package specification, so they can be referenced only by other objects in the package. They cannot be referenced outside the package.
  See Also:
  - Oracle Database PL/SQL Language Reference
  - Oracle Database Advanced Application Developer's Guidefor more information on creating new packages
  - Oracle Database Concepts
  for more information on storing and executing packages

Separating the Specification and Body

The specification of a package declares the public types, variables, constants, and subprograms that are visible outside the immediate scope of the package. The body of a package defines the objects declared in the specification, as well as private objects that are not visible to applications outside the package.

Oracle stores the specification and body of a package separately in the database. Other schema objects that call or reference public program objects depend only on the package specification, not on the package body. Using this distinction, you can change the definition of a program object in the package body without causing Oracle to invalidate other schema objects that call or reference the program object. Oracle invalidates dependent schema objects only if you change the declaration of the program object in the package specification.

Creating a New Package: Example

The following example shows a package specification for a package named EMPLOYEE_MANAGEMENT. The package contains one stored function and two stored procedures.

CREATE PACKAGE employee_management AS
   FUNCTION hire_emp (name VARCHAR2, job VARCHAR2,
      mgr NUMBER, hiredate DATE, sal NUMBER, comm NUMBER,
      deptno NUMBER) RETURN NUMBER;
   PROCEDURE fire_emp (emp_id NUMBER);
   PROCEDURE sal_raise (emp_id NUMBER, sal_incr NUMBER);
END employee_management;

The body for this package defines the function and the procedures:

CREATE PACKAGE BODY employee_management AS
   FUNCTION hire_emp (name VARCHAR2, job VARCHAR2,
      mgr NUMBER, hiredate DATE, sal NUMBER, comm NUMBER,
      deptno NUMBER) RETURN NUMBER IS

The function accepts all arguments for the fields in the employee table except for the employee number. A value for this field is supplied by a sequence. The function returns the sequence number generated by the call to this function.

       new_empno    NUMBER(10);

   BEGIN
      SELECT emp_sequence.NEXTVAL INTO new_empno FROM dual;
      INSERT INTO emp VALUES (new_empno, name, job, mgr,
         hiredate, sal, comm, deptno);
      RETURN (new_empno);
   END hire_emp;

   PROCEDURE fire_emp(emp_id IN NUMBER) AS

The procedure deletes the employee with an employee number that corresponds to the argument emp_id. If no employee is found, then an exception is raised.

   BEGIN
      DELETE FROM emp WHERE empno = emp_id;
      IF SQL%NOTFOUND THEN
      raise_application_error(-20011, 'Invalid Employee
         Number: ' || TO_CHAR(emp_id));
   END IF;
END fire_emp;

PROCEDURE sal_raise (emp_id IN NUMBER, sal_incr IN NUMBER) AS

The procedure accepts two arguments. Emp_id is a number that corresponds to an employee number. Sal_incr is the amount by which to increase the employee's salary.

   BEGIN

   -- If employee exists, then update salary with increase.
   
      UPDATE emp
         SET sal = sal + sal_incr
         WHERE empno = emp_id;
      IF SQL%NOTFOUND THEN
         raise_application_error(-20011, 'Invalid Employee
            Number: ' || TO_CHAR(emp_id));
      END IF;
   END sal_raise;
END employee_management;

Note:

If you want to try this example, then first create the sequence number emp_sequence. You can do this using the following SQL*Plus statement:

SQL> CREATE SEQUENCE emp_sequence
   > START WITH 8000 INCREMENT BY 10;

Referencing Package Contents

To reference the types, items, and subprograms declared in a package specification, use the dot notation. For example:

package_name.type_name
package_name.item_name
package_name.subprogram_name
