WCF和MVC：从Web MVC应用程序调用存储过程

Question

I've done a wcf service that deals with a database. In that WCF service i've created some stored procedures. That service is now accessible from my network (http: //myIP/MysService.csv/) and my stored procedures are accessible that way : http: //myIP/MysService.csv/MyProcedure?myParam=XXX.

I've a MVC4 application that is working with some local data (by local I mean a local database and a local WCF service, called that way for requests by example :

public int getClientID(string login)
    {
        var context = new MyLocalService.MyLocalEntityEntities(new Uri(http://localhost:12345/MyWCF.svc/));
        var persons = context.PERSON.ToList();

        var cli = from person in persons
                     where person.LOGIN == login
                     select person.CLIENT_ID;

        int cliID = (int) cli.First();
        return cliID;
    }

Now, I'd like to plug the 2 : delete all the part that works with local data (var context=...) and replace it by a call to the stored procedure of my WCF service. How to do it ?

I've try to add my service using right click-> add as a service reference -> http: //myIP/MysService.csv/ for address by I cannot access to stored procedures. Is it the right way to work and if not, how to do it ? Thanks !

Answer 1

If you're going to use Stored Procedures then look at the SqlCommand class that will allow you to execute stored procedures on the database.

The other idea would be to consider what kind of Object-Relational Mapping tool you are using that may allow for SQL commands to be executed directly since you already seem to be using some LINQ in your code.

You'd pair the SqlCommand class with a SqlConnection class that have a direct connection to the database, presuming the stored procedure is MS-SQL Server or SQL Express where you want to execute the procedure in the DB. Unless you have a very different configuration than what I've seen, most calls to stored procedures are done by wrapping some using statements for the connection and command to run the procedure. Calling stored procedure from C# code has an example if you need it.
