PL/SQL (Procedural Language/SQL) is a procedural language extension to SQL for the Oracle database, offering a way to mix SQL statements with procedural constructs. It's used to write stored procedures, functions, and packages within Oracle databases, enabling more complex logic and data manipulation

Key Features and Components:

• Procedures, Functions, and Packages : PL/SQL allows you to define and store reusable code blocks called procedures, functions, and packages, which can be called from other PL/SQL blocks or SQL statements
• Block Structure : PL/SQL is a block-structured language, meaning that code is organized into logical blocks, which can be nested
• Control Flow : It offers features like loops (WHILE, FOR, LOOP), conditional statements (IF-THEN-ELSE), and exception handling, enabling more complex control flow logic within the database
• Variables and Data Types :PL/SQL allows you to declare variables, constants, and use various data types to store data, including those defined in SQL
• Cursors : PL/SQL uses cursors to process query result sets row by row, offering precise control over data retrieval and manipulation
• Triggers : PL/SQL triggers are special procedures that automatically execute in response to certain database events, such as data changes, enabling actions to be taken when certain conditions are met
