PL/SQL (Procedural Language for SQL) is Oracle’s proprietary extension to standard SQL. It combines the data manipulation power of SQL with the procedural capabilities of a programming language.

This language is tightly integrated with Oracle databases, enabling efficient data processing and transaction management.
