Tuning PL/SQL code

We have just discussed two key features in the performance management space. The PL/SQL code optimization and compilation can significantly improve runtime performance. Apart from the code optimization techniques, there are several efficient coding practices that may impact overall PL/SQL performance. PL/SQL performance management is often regarded as less tedious, when compared to the database tuning exercise because the area of operation is a program unit and doesn't require the instance to be restarted. In this section, we will discuss some of the selective but key features to improve PL/SQL coding practices for better performance.

Build secure applications using bind variables

It is highly encouraged to use bind variables in SQL statements while building robust database applications. Bind variables reduce the parsing overhead by enabling an SQL statement to be executed using its already parsed image stored in the shared SQL area of the database memory.

Every SQL statement...
