PL/SQL

PL/SQL (Procedural Language/Structured Query Language) is a procedural extension of SQL, specifically designed for Oracle Database. It is a block-structured language that enables developers to write stored procedures, functions, triggers, and packages within the Oracle Database environment. PL/SQL combines the data manipulation capabilities of SQL with the procedural programming features of traditional programming languages like loops, conditions, variables, and exception handling. It provides a powerful and flexible programming environment for developing database-centric applications.

PL/SQL is widely used in Oracle Database environments for developing database-centric applications, implementing business logic, and improving the performance and manageability of database operations. It provides a powerful and efficient way to interact with the Oracle Database and leverage the SQL capabilities in a procedural programming environment.
