Writing a stored procedure in sql server 2008
This procedure accepts only exact matches for the parameters passed. Drag and drop this template on the TSQL interface. Type in the following query for creating a stored procedure: Select the query and click on Execute to create it.
Organizations where SQL Server system is used for database storage and maintenance, projects with s of database tables and stored procedures are common to find.
Security Users can execute a stored procedure without needing to execute any of the statements directly. To do so, execute the following script: Select the query and click on Execute from the top to run the query. For example, a stored procedure can accept parameters that are passed to it and test against those parameters using IF statements.
The procedure takes one input parameter, NewHours and one output parameter RowCount.
Stored procedures can improve performance in an application, because the stored procedure is parsed and optimized as soon as it's created, and then stored in memory. For example, if we want to execute the stored procedure "Getstudentname", then we will use the following statement.
Execute stored procedure with parameters
Road Black, 48 Select and expand the preferred database for which you want to create stored procedure. Their ability to contain business logic makes stored procedures a powerful part of SQL Server. Using TRY Because the stored procedure is not dropped, so we don't have to worry about reassigning permission to it after modifying it. Execute Getstudentname 1 Exec Getstudentname 1 Execution of the Stored Procedure using the Output Parameter If we want to execute the Stored procedure "GetstudentnameInOutputVariable" , then we first need to declare the variable to collect the output values. Sometimes, it is useful to use the database for storing the business logic in the form of stored procedure since it makes it secure and if any change is needed in the business logic, then we may only need to make changes in the stored procedure and not in the files contained on the web server. Running the code on the SQL Server as a stored procedure eliminates the need to send this code over the network. ResellerName, r. This procedure accepts only exact matches for the parameters passed. Running a conditional query via stored procedure can be extremely quick - compared to an application that sends a query across the network, to the SQL Server, then has all the data returned to it across the network so it can filter through it, and pick out only the records it's interested in. You will find your Stored Procedure Created by its name, i. In the example, the option CALLER specifies that the procedure can be executed in the context of the user that calls it.
CATCH construct to return error information caught during the execution of a stored procedure. For example: Declare Studentname as nvarchar -- Declaring the variable to collect the Studentname Declare Studentemail as nvarchar 50 -- Declaring the variable to collect the Studentemail Execute GetstudentnameInOutputVariable 1Studentname output, Studentemail output select Studentname, Studentemail -- "Select" Statement is used to show the output from Procedure Summary In the end, we can say that a Stored procedure not only enhances the possibility of reusing the code and execution plan, but it also increases the performance of the database by reducing the traffic of the network by reducing the amount of information sent over the network.
Type of stored procedure in sql server
In SQL Server, stored procedures are much more powerful than views. A global temporary stored procedure can be accessed by multiple connections and exists until the connection used by the user who created the procedure is closed and any currently executing versions Of the procedure by any other connections are completed. Faster execution: Stored procedures are parsed and optimized as soon as they are created and the stored procedure is stored in memory. There can be a case when a stored procedure doesn't returns anything. On SQL Server, system stored procedures can be found within the master database. Moreover, it is in most cases possible that a reliable result in not generated while trying to identify the impacted procedure out of all the rest. User Logins Stored procedures can improve security and performance, as well as increase productivity by facilitating modular development. Using TRY If you are keen on creating your own SQL Server system Stored Procedure too, following these steps will help achieve desired results.
