Introduction to PL/SQL Packages and Package Bodies. A PL/SQL package stores related items as a single logical entity. A package is composed of two distinct pieces: The package specification defines what is contained in the package; it is analogous to a header file in a language such as C++. The specification defines all public items. The specification is the published interface to a package. We can divide the PL/SQL procedure into two sections: header and body. PL/SQL Procedure Header The section before IS keyword is called procedure header or procedure signature. The elements in the procedure's header are described as follows: schema: the optional name of the schema that the procedure belongs to. The default is the current user. Create stored procedures and functions. Use PL/SQL packages to group and contain related constructs. Create triggers to solve business challenges. Use some of the Oracle supplied PL/SQL packages to generate screen output and file output. Create custom packages for applications. Write Dynamic SQL code for applications. •A stored procedureis a PL/SQL block that Oracle stores in the database and can be called by name from an application. May or may not return a value. •Functionsalways return a single valueto the caller; procedures do not returnvalues to the caller. •Packagesare groups of procedures and functions. PL/SQL Blocks You can also execute a procedure from the Oracle SQL Developer using the following steps: 1) Right-click the procedure name and choose Run… menu item 2) Enter a value for the in_customer_id parameter and click OK button. 3) The following shows the result Connecting to the database Local. Elisha Lloyd Process exited. 1 Overview of Procedures •A procedure is a named PL/SQL block that performs an action. •A procedure can be stored in the database, as a database object, for repeated execution.
