4-10. Writing Initialization Code for a Package

Problem

You want to execute some code each time a particular PL/SQL package is instantiated in a session.

Solution

Create an initialization block for the package in question. By doing so, you will have the ability to execute code each time the package is initialized. The following example shows the same package that was constructed in Recipe 4-7. However, this time the package contains an initialization block.
