PL/SQL Data Types: PL/SQL Data Types define the characteristics and behavior of variables and functions in a PL/SQL program. It ensures the proper storage, manipulation, and representation of data, improving the overall integrity and efficiency of the application.
PL/SQL Variables and Constants: PL/SQL Variables and Constants are used to store and manipulate data within a program. They provide a way to store temporary or permanent values, facilitating calculations, comparisons, and other operations.
PL/SQL Control Structures: PL/SQL Control Structures enable the flow of execution in a program, allowing developers to control the order and conditions under which statements are executed. They provide mechanisms for loops, conditionals, and branching, enhancing the flexibility and control of the program flow.
PL/SQL Cursors: PL/SQL Cursors are used to retrieve and manipulate data from the database. They provide a mechanism for traversing and processing query results, allowing developers to perform complex data operations in their applications.
PL/SQL Stored Procedures: PL/SQL Stored Procedures are named blocks of code that can be executed repeatedly. They encapsulate business logic and database operations, offering modularity and reusability to the application.
PL/SQL Functions: PL/SQL Functions are subprograms that can be called from within SQL statements. They return a single value and can be used in various database operations, providing modularity and convenience in data manipulation.
PL/SQL Exceptions: PL/SQL Exceptions are used to handle errors and exceptional situations within a program. They provide a way to gracefully handle unexpected scenarios, ensuring data integrity and application stability.
PL/SQL Packages: PL/SQL Packages are collection of related procedures, functions, variables, and cursors. They offer encapsulation, better organization, and maintainability of code, providing a modular approach to code development and deployment.
PL/SQL Triggers: PL/SQL Triggers are special stored procedures that are automatically executed in response to specific events in the database. They are used to enforce data integrity, perform auditing tasks, or automate data-related actions, enhancing the functionality and control of the database.
