存储过程到Web服务

Question

I would like to know if there is an automatic (or effortless) way to map SQL Server stored procedures to web services?

The problem is, I need to allow a third party application to interact/integrate data with an ERP system. This ERP provides several stored procedures to do that. Those stored procedures also contain validation and tons of business logic.

But, this external app prefers to go through web services.

So, the first approach is to create a web service and map each stored procedure to a method (or may be split in different endpoints) but, I don't know is there is some tool, if it can be done using Entity Framework, etc.

Answer 1

You could write something yourself using SMO (Sql management objects), if we are talking about 2 stored procs it may not be worth it but if its 100...

this is a demonstration to use SMO. the same idea could be used for writing out your service contract etc.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.SqlServer.Management.Common;
using Microsoft.SqlServer.Management.Smo;


    class Program
    {
        static void Main(string[] args)
        {

            Server srv = new Server("serverName");
            Database db = srv.Databases["myDBName"];

            foreach (StoredProcedure proc in db.StoredProcedures)
            {

                StringBuilder methodWriter = new StringBuilder();

                methodWriter.Append("public void " + proc.Name + "(");

                foreach(Parameter param in proc.Parameters)
                {
                    string csharpData = string.Empty;

                    if (param.DataType == DataType.DateTime) { csharpData = "DateTime " + param.Name; }
                    //...

                    methodWriter.Append(csharpData + ", ");

                }

                methodWriter.Append("){}");

            }

        }
    }
