It is believed that many inexperienced people don't know what to do about how to create stored procedures in SQLServer database. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

How to create and apply stored procedures in SQLServer Database

1. Stored procedures greatly enhance the function and flexibility of sql language. Stored procedures can be written with flow control statements and have strong flexibility.

two。 Stored procedures can ensure the security and integrity of data. Through stored procedures, users who do not have permissions can access the database indirectly under control, thus ensuring the security of data. Through the storage structure, the related actions can occur together, thus the integrity of the database can be maintained.

3. The stored procedure can be executed quickly. Before running the stored procedure, the database has analyzed the syntax and syntax of the stored procedure, and given the optimized execution scheme. This compiled process can greatly improve the performance of sql statements, and most of the work of executing sql statements has been completed.

4. To some extent, it can reduce the traffic of the network. If it is a sql statement, you must pass the sql statement to the server and then execute the sql statement.

5. You can centrally control sql statements: for example, when a company's rules change, as long as you change the stored procedures on the server, the general company's rules often change, if you put the operation program that reflects the rules into the application, then when the company rules change, the workload of modifying the application is very large, and you have to modify, release and install the application. If you put the rules in the stored procedure, when the enterprise rules change, you only need to modify the stored procedure, and the application does not need to change.

CreatePROCEDURE[dbo] .[news _ selectNewNews] ASBEGINselecttop10n.id,n.title,n.createTime,c. [name], c.idascaIdfromnewsninnerjoincategoryconn.caId=c.idorderbyn.createTimedescEND

When executing the stored procedure, the stored procedure built in the database is handed over to the interface layer and then passed to the Dal layer for processing. As long as commandtype=StoredProdure is set, the database can handle the stored procedure.

PublicDataTabletest (stringProcName) {DataTabledt=newDataTable (); Cmd=newSqlCommand (procName,GetConn ()); (open connection, pass in stored procedure) cmd.CommandType=CommandType.StoredProcedure; (difference between executing sql statement and stored procedure) using (sdr=cmd.ExecuteReader (CommandBehavior.CloseConnection)) {Dt.load (sdr);} Returnsdr;}
