, 1.Introduction to SQL Stored Procedures
SQL Stored Procedures are precompiled collections of SQL statements stored inside the
database. Instead of writing SQL queries repeatedly, developers can save a set of instructions as
a procedure and execute it whenever needed. This makes database operations more efficient,
reusable, and organized.
In real-world systems, applications often need to perform repetitive database tasks such as
inserting records, updating data, or generating reports. Writing the same queries multiple times
increases complexity and the chances of errors. Stored procedures solve this problem by
encapsulating logic into a single reusable unit.
When a stored procedure is executed, the database engine processes it as a compiled object.
This reduces execution time compared to running individual queries repeatedly. Stored
procedures also help in reducing network traffic because multiple operations can be executed in
a single call.
Understanding stored procedures is essential for backend development and database
optimization. They are widely used in enterprise applications where performance, security, and
maintainability are critical.
