How to create stored procedure in SQL server?

Before going to How to create stored procedure in SQL server 2008? We will check benefits of using stored procedure in SQL server. Stored procedure in SQL can be defined as group of SQL statements which have been collected to perform some specific task. There are different benefits of using the process while the main one is it increases the performance of database thus increasing the output. The stored procedure is competent in bringing out number or result set and status code.

Advantages of create stored procedure in SQL server

One of the main benefits of using a stored procedure is it reduces the amount of information which is sent to the server. This becomes all the more useful when the bandwidth of the network is less. On the contrary, the SQL statement is executed in the form of a loop between server and network, and in the meanwhile if the network gets disconnected, then the SQL statement does not produces the required results or results which are expected by the user.

  • Compilation

Compilation

Compilation process has to be undergone only at the time when stored procedure is created, and once it has been done one need not have to undertake the compilation process again, unless some modifications are made. Whereas in the SQL statement compilation has to be done every time whenever it is sent for some execution does not matter if the same SQL statement is sent every time.

  • Reduce development time

The SQL code can be used by many times and that too by different clients in case of stored procedure, but in the case of SQL same statement has to be written every time again and again. The use of stored procedure has thus reduced the development time.

  • Secure

Stored procedure adopts a more safe and secures method because permission is only granted for execution of the stored procedure and does not permits access to tables which are used in stored procedure.

 

When to use the stored procedure?

It is mostly suitable for two tier environments, however with time its use has shifted to three tier environments as well. In three tier environment the use is often restricted to basic data related tasks which consists of select, update and delete.

While creating the procedure the first important thing to do is create a unique name of the procedure within the scheme, and then mention the SQL statements which have to be executed as a part of the process. Following steps have to be undertaken to complete the process;

  • Expand database and then select pubs
  • Select programmatically and select the stored procedure
  • Right click on the tab and then select the new stored procedure
  • After this, the SQL opens a new query window which has a default stored procedure template stored in it.

From the above it can be clearly made out, that using stored procedure for storage of business logic is much more safe especially when changes has to be made in the business logic. Making changes is much easier in case of stored procedure as all the files are contained and stored in the web server.

 

Example: How to create stored procedure in SQL server using Code

How to create stored procedure in SQL 2012
How to create stored procedure in SQL server

In this example we look simply create SQL Server Stored Procedures in SQL server 2008 R2.

Here we create simple select statement with help of stored procedure by passing parameter

CREATE PROCEDURE Select Data

      — Add the parameters for the stored procedure here

      @title nvarchar(5)

     AS

     BEGIN

  — Insert statements for procedure here

      select * from SalesLT.Customer

     where Title=@title

END

GO

Explanation:

We create Select Data as Procedure to select all records from customer table.To filter data from selected table we pass title as parameter.To pass value use @ at the time of initialization and data types.

 

After execution of stored procedure result will be Command(s) completed successfully.

 

To call stored procedure in SQL server to view the contents from the table specified and pass value.

 

EXEC Select Data @title = ‘Mr.’

Similarly Code for insert data using stored procedure with parameter in SQL server is:

CREATE PROCEDURE Insert data

— Add the parameters for the stored procedure here

      @AddressLine1 nvarchar (50),

      @City nvarchar (40)

AS

BEGIN

  — Insert statements for procedure here

      insert into SalesLT.Address (AddressLine1,City) values (@AddressLine1,@City)

END

GO

Delete stored procedure 2014

Limitation:

Deleting a procedure will cause dependent objects and scripts to fail once the objects and scripts don\’t seem to be updated to mirror the removal of the procedure. However, if a replacement procedure of identical name and therefore the same parameters is made to exchange the one that was deleted, alternative objects that reference it\’ll still method with success.

Stored procedure drawbacks

drawback
How to create stored procedure in SQL server

Stored procedure is used to optimize load and enhance the performance of code execution, but stored procedures have some drawbacks. Thus stored procedure not always best solution to application database access.

Following list indicate reasons why stored procedure not perfect for application solution.

Limited Coding Functionality

Stored procedure code is not as long-lasting as application code, mostly in the zone of looping. We face lots of limitation while coding stored procedure.

  • Portability

Compound Stored Procedures that employ complex, core functionality of relational database management system used for their modelling will not always port to improve versions of the same database.

  • Testing

Most important drawback of stored procedure in SQL server is does not shows error until run time. It is very hard to debug.

  • Location of Business Rules

Since stored procedure in SQL server as simply grouped/encapsulated along in single files, this additionally implies that business rules square measure unfold throughout completely different keep Procedures. App code design helps to make sure that business rules square measure encapsulated in single objects.

There may be a general opinion that business rules / logic shouldn’t be housed within the knowledge tier.

Utilization of Set-based process

Too a lot of overhead is incurred from maintaining keep Procedures that square measure not complex enough. As a result, the final accord is that straightforward choose statements shouldn’t be absolute to keep Procedures and instead enforced as inline SQL.

 

  • Cost

Depending on your company structure and separation of concern for development, there\’s the potential that keep Procedure development may probably need an infatuated information developer. Some businesses won\’t permit developers access to the information in the slightest degree, requiring instead a separate DBA. This can mechanically incur value-added value.

Some firms believe (and generally it\’s true, however not always) that a DBA is a lot of of a SQL knowledgeable than AN application developer, and so can write higher keep Procedures. Therein case, an additional developer within the variety of a DBA is needed.

 

 

 

 

 

 

Alternatives to hold on stored Procedures

Because hold on Procedures aren’t\’t invariably the proper answer nor do they satisfy all the requirements of all developers, alternative solutions exist that conceive to give most of what a developer needs to try and do once accessing an information back end.

These include:

  • In-line or Parametrized Queries
  • These are written inside the appliance code itself
  • Object relative Mapping (ORM)

Provides AN abstraction to the information while not having to manually write information access categories. At this time, most all major platforms provide some style of ORM software package, as illustrated at this

 

Conclusion

Stored procedure have many benefits and few drawbacks. To increase performance of SQL query and reduce development time it is best solution. Some time in application access have some drawbacks. Here we try solve most important question how to create stored procedure in SQL server.
