Have you participated in developing or writing stored procedures in your projects?

Yes, stored procedures are often used in projects to perform logic on the database side.

Stored procedures allow:

• Performing complex data operations directly in the DBMS, which increases performance by reducing the amount of data transferred.
• Centralizing business logic, making it easier to support and modify.
• Ensuring security by restricting direct access to tables.

In Java applications, interaction with stored procedures usually occurs through JDBC using CallableStatement. An example of calling a stored procedure:

CallableStatement stmt = connection.prepareCall("{call getUserById(?)}");
stmt.setInt(1, userId);
ResultSet rs = stmt.executeQuery();
// process the result
