False
Suppose that you are using Oracle 11g Release 2 express edition and you issue the following command:
ALTER SESSION SET PLSQL_WARNINGS = 'ENABLE:ALL' / Session altered. ALTER FUNCTION FUNC COMPILE PLSQL_DEBUG=TRUE / Function altered.
Determine the output of the following
SELECT
statementSELECT * FROM USER_ERRRORS /
No output
PLW-06015: parameter PLSQL_DEBUG is deprecated; use PLSQL_OPTIMIZE_LEVEL = 1
PLW-06013: deprecated parameter PLSQL_DEBUG forces PLSQL_ OPTIMIZE_LEVEL <= 1

The Oracle Advanced PL/SQL Developer Professional Guide helps you master advanced PL/SQL concepts. Besides the clear and precise explanation on advanced topics, it also contains example code and demonstrations, which gives a sense of application and usage to readers.The book gives a deep insight that will help transform readers from mid-level programmers to professional database developers. It aims to cover the advanced features of PL/SQL for designing and optimizing PL/SQL code.This book starts with an overview of PL/SQL as the programming database language and outlines the benefits and characteristics of the language. The book then covers the advanced features that include PL/SQL code writing using collections, tuning recommendations using result caching, implementing VPD to enforce row level security, and much more. Apart from programming, the book also dives deep into the usage of the development tool SQL Developer, employing best practices in database environments and safeguarding the vulnerable areas in PL/SQL code to avoid code injection.
