Overview of PL/SQL
What is PL/SQL?
PL/SQL (Procedural Language/SQL) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database, TimesTen in-memory database, and IBM DB2.
Features of PL/SQL
- Integrated SQL: PL/SQL fully integrates with SQL to leverage SQL’s data manipulation capabilities, making it easier to develop data-centric applications.
- Error Handling: PL/SQL provides a robust error handling mechanism, making it easier to debug and manage exceptions.
- High Performance: PL/SQL is designed for high performance and efficiency, allowing you to perform complex operations with minimal code.
- Portability: Applications written in PL/SQL can run on any operating system or hardware platform supported by Oracle Database.
PL/SQL Architecture
PL/SQL is designed to run in the Oracle Database server or an application development tool that integrates with Oracle Database. It offers various features such as anonymous blocks, stored procedures, functions, packages, and triggers that enhance the capability to handle complex operations efficiently.
Advantages of PL/SQL
PL/SQL offers several advantages for developers working with Oracle Database:
- Improved productivity with tight integration between SQL and procedural code.
- Increased performance with stored procedures and functions executed directly on the server.
- Enhanced security with robust error handling and transaction control.
