Stored procedure in PLSQL

A stored procedure in PL/SQL is a named block of code that can be stored in the database and executed later, encapsulating a sequence of SQL statements and conditional logic. Stored procedures are often used for repetitive tasks, data manipulation, and to encapsulate business logic. They offer modularity, performance, security, and transaction control benefits. The syntax of a stored procedure includes a procedure name, parameters, declaration section, executable section, and exception handling section. A stored procedure can accept parameters, manage transactions, and enforce business rules. The example provided shows a simple stored procedure that inserts a new employee record into an employees table. The procedure takes five parameters, inserts a new record, and commits the transaction, with exception handling for duplicate employee IDs and other errors. To execute the stored procedure, you can use an anonymous PL/SQL block or directly call it from SQL. Stored procedures are powerful tools for encapsulating business logic, improving performance, and ensuring security in database applications. They allow developers to write reusable code that can manage complex tasks, making it easier to maintain and scale database systems.
