Description
A stored procedure is a precompiled collection of SQL statements stored in a database for repeated execution. It encapsulates complex logic, enhances performance, and promotes code reusability in database operations.
Features
- Parameterized input and output
- Supports conditional statements and loops
- Reduces network traffic
- Improves security through encapsulation
- Allows transaction management
- Enables modular programming in database logic
Limitations
- Platform-dependent syntax
- Debugging challenges
- Potential overuse leading to business logic in database
- Version control difficulties
- Limited portability between different database systems
- Increased database server load with complex procedures
Use Cases
- Batch data processing: Efficiently process large datasets with complex transformations and validations in a single database call.
- User authentication: Implement secure, centralized user authentication logic, including password hashing and role assignment.
