Oracle 12c SQL and PL/SQL new features
SQL is the most widely used data access language while PL/SQL is a popular language that can integrate seamlessly with SQL commands. The biggest benefit of running PL/SQL is that the code processing happens natively within the Oracle Database. In the past, there have been debates and discussions on server side programming while the client invokes the PL/SQL routines to perform a task. The server side programming approach has many benefits. It reduces the network round trips between the client and the database. It reduces the code size and eases the code portability because PL/SQL can run on all platforms, wherever Oracle Database is supported.
Oracle Database 12c introduces many language features and enhancements that focus on SQL to PL/SQL integration, code migration, and ANSI compliance. This section discusses the SQL and PL/SQL new features in Oracle Database 12c.
