Stored Procedure in SQL Server
A stored procedure is an accumulation of MS SQL arguments such as collection of MS SQL commands and logical relations between data and statements, etc. Stored procedure are also called as database objects and they can be stored in the database data dictionary. When a very large and logical operation needs to execute in a SQL sever command at a time, then MS SQL Server statements follow the stored procedure.
Types of Stored Procedures In SQL Server
There are four types of stored procedure in the SQL Server.
- User-defined stored procedure
- Temporary stored procedure
- System stored procedure
- Extended Stored Procedure
Advantages of Using Stored Procedure in SQL Server
The SP’s are compiled once and stored in the executable form, that’s why stored procedures are quick and efficient. The executable code is automatically shared by the users. This technique needs lower memory space and serves all DBA’s related to the same database. The grouping of statements provides the feature to execute the statement in only one cell; this technique also reduces the network traffic problem, unhealthy network and improves the rounding time amongst all users.
Scalability and Maintainability:
The stored procedures improve the scalability using the inbuilt technic isolation processing technique. If SP (stored procedure) is authenticated, then it can serve to several numbers of applicants. If the definition of Stored Procedure is changed, then only the created procedures get affected, and not the influenced applications that uses this. This feature of SP’s makes it easy to maintain and improve.
Security is the most important part of any database that can’t be ignored. Using the stored procedure in MS SQL Server you can escape accessing the Oracle data; the stored procedure only gives access permission to manipulate the data. This means that you can grant/revoke permission on an individual stored procedure. As we know that maintaining a procedure is easier than maintaining all applications.
Disadvantages of Stored Procedure in SQL Server
Less Coding Facility:
The coding facility of SP’s is not powerful like app code, mostly in the looping technique and stored procedures are unable to show the iterative constructs etc. The code writing and its maintaining needs a much-specialized skilled person.
Stored procedures are also, may be, different from one database to another. The stored procedures are tightly bounded with the databases. One major disadvantage is that the stored procedure sometimes also unable to use the objects.
A large stored procedure code which is designed using the RDBMS bottom line functionality of coding, also sometimes makes difficulties to move the code in same upgraded version of databases. These problems mostly come to see when we port the SP’s from Oracle to another SQL Server database.
In stored procedure, absence of error handling technique is also a major problem. Stored Procedure does not generate the error handling until the runtime of data. Stored procedure doesn’t have a debugger tool, that can help at the designing time of procedure.
After all, stored procedures are not smoothly encapsulated or merged together in a single file. This means that the business rules are span for the stored procedures.
Importance of Stored Procedure in SQL Server
Stored procedures are very important for the administrative purpose that’s why stored procedures should be well maintained. A stored procedure reduces the client and server network traffic. The stronger security facility monitors the processes and activities that are cardinal.
Pre-compilation activity may cause slow the stored procedure, but we can come out this situation by forcing a new execution plan. This error message can be occur, if you working on SQL Server Error 0: [SQL-DMO] Object 'dbo.SP_ProcName' was not scripted.
Reasons of SQL Server Stored Procedure Corruption
Frequent Corruption Reasons of Stored Procedure are as follows.
1. Platform Issue: More of the 95% corruption cases is related to the platform of stored procedures which is a layer below to the SQL Server.
2. Third Party Driver and Firmware Bugs: These are also individual corruption reasons of the stored procedures in database.
3. Actual Hardware Failure: These types of corruption issues are like the failure of the disk controller, CPU or memory modules etc.
4. Disk Subsystems: The communication channels or even the disk driver are running smoothly.If any error encountered, then go to the hardware vendor because hardware failure is the most common issue for a stored procedure corruption. The hardware specialist should check the driver, firmware and: BIOS to ensure that these are running normally.
In the present blog, we have discussed the benifits of using stored procedure (SP) and its advantages & disadvantages. And how stored procedures are important in SQL Server database.
