What is Oracle PL/SQL ?


Oracle PL/SQL is a procedural language designed specifically to embrace SQL statements within its syntax.  Oracle PL/SQL program units are compiled by the Oracle Database server and stored inside the database. And at run-time, both PL/SQL and SQL run within the same server process, bringing optimal efficiency.
