Intoduction to Stored Procedures in SQL Server
SQL Server uses Different types of stored procedures. They are the quickest method of accessing and manipulating database on the server. SPs are codes and scripts that are predefined for repetitive tasks to be performed on the server involving a database/its table/pages, etc. The usage is largely done by server administrators to prevent time consumption. SPs help in quickening the pace of an executing a task on SQL Server as they offer an enhanced level of performance with ease of use and increased scalability resulting in better productivity.
The defined purpose of stored procedures is to serve the following roles:
- Server Stored Procedures help in database management, validation, and controlling.
- Input or typing in of long stringed queries is a process avoidable with the help of SPs
- Stored procedures can be granted permissions, which increase the level of security.
- Network traffic is reduced, as recompilation is not required.
- Stored procedures are complex but the fact that they only need to be written once and not repeatedly makes them preferable overwriting codes/scripts for executing every other task. The easy reusability makes SPs highly preferred.
List of Advantages of Using Stored Procedures in SQL Server
They Are Modular
Stored procedures in SQL Server are modular, meaning codes written with standard functions. SPs are regarded well from maintenance point. It is comparatively way easier to deal with and troubleshoot an issue encountered with the stored procedure than when it happens with an embedded query that lies below a number of GUI code lines.
They Are Tunable
You are not supposed to make changes in the GUI source code for making improvements in a query performance. Procedures take control and handle the database work on your interface’s behalf. Table differing, joining methods and similar changes can be made to stored procedures in the condition of UI transparency.
They Are Secure
Stored procedures are quite a security as due to their usage, a limit amount of direct access is made to the database tables with the use of defined roles. In addition, the SPs render the fundamental data structure with an interface. This helps in shielding the data and implementations made to it. Moreover, implementation of security on the data and code that has access to it is relatively easier than implementing the same on the entire application code.
Usage of stored procedures is limited to certain conditions and executions only, therefore, besides advantages, there are also disadvantages of using SPs. Sometimes, stored procedures in SQL Server are inaccessible and display error messages according to the failure. However, running the DBCC CHECKDB against the failure may fix the issue but it depends on corruption level.
