Introduction to PL/SQL
Lakshman Bulusu · Apress eBooks · 2003
O racle first introduced Procedural Language/Structured Query Language (PL/SQL) in version 6.0 of its relational database management system (RDBMS). As its RDBMS evolved, Oracle made developmental changes to the PL/SQL language by introducing new features and enhancing existing features. As of Oracle9 i , the version of PL/SQL is PL/SQL 9.2 or 9.0 depending on whether it is Oracle9 i Release 2 (9.2. x ) or Oracle9 i Release 1 (9.0. x ). In this book, I refer to both versions collectively as PL/SQL 9 i . These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
