As we all know, few of us work in isolation; most PL/SQL development work is carried out in a relatively large organization. But we basically work with our own device in our own compartment. Almost no PL/SQL development team performs formal code review or system testing. 1. Strictly follow naming convention

Abstract: In the PL/SQL development process, SQL, PL/SQL can be used to meet most of the requirements. However, in some special cases, standard SQL statements or DML statements in PL/SQL cannot meet your needs.
