Summary

In this chapter, you learned why PL/SQL is such an important tool for a JDBC developer. You examined some PL/SQL techniques to increase the performance and maintainability of your code. These techniques included putting your code in packages, using bulk operations to improve performance, and preferring static SQL to dynamic SQL when you have a choice. You also learned about invoker rights and definer rights modes in PL/SQL, and when to use each mode. You then looked at PL/SQL debugging techniques and enhanced a custom PL/SQL package called debug, using which you can instrument your Java and PL/SQL code.
