Question

下面定义的是存储过程，它有两个insert语句。

 USE [RHK_HIS]
 GO
 /****** Object:  StoredProcedure [dbo].[createuser]    Script Date: 01/23/2014      11:50:09 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO




 ALTER PROCEDURE [dbo].[createuser]
-- Add the parameters for the stored procedure here
  ( @User_Id varchar(15),
  @Password varchar(15),
  @Name varchar(30),
  @Role_Id varchar(10),
  @Department_Id varchar(10),
   @Active varchar(1)
  )
 AS
 BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
insert into User_M (User_Id,Password,Name,Role_Id,Department_Id,Active) values   (@User_Id,@Password,@Name,@Role_Id,@Department_Id,@Active)
insert into User_Dept_Map(User_Id,Dept_Id) values (@User_Id,@Department_Id)
 END

通过下面指定的函数在Connection.cs中调用存储过程

    public int create_user(UserMaster ua)
{
    SqlConnection Con = new SqlConnection(str);
    Con.Open();
    SqlCommand Cmd = new SqlCommand("createuser", Con);
    Cmd.CommandType = CommandType.StoredProcedure;
    try
    {
        log.Debug("Inside Create user");
        Cmd.Parameters.AddWithValue("@User_Id", ua.UserName);
        Cmd.Parameters.AddWithValue("@Password", ua.Password);
        Cmd.Parameters.AddWithValue("@Name", ua.Name);
        Cmd.Parameters.AddWithValue("@Role_Id", ua.Role);
        Cmd.Parameters.AddWithValue("@Department_Id", ua.Department);
        Cmd.Parameters.AddWithValue("@Active", ua.Active);
        log.Debug("Inside Create_User: New User created having ID: " + ua.UserName);
        log.Info("user created");
        return Cmd.ExecuteNonQuery();
    }
    catch (Exception e)
    {
        log.Debug("Error: Inside catch block of Create User");
        log.Error("Error msg:" + e);
        log.Error("Stack trace:" + e.StackTrace);

        throw e;
    }
    finally
    {
        Cmd.Dispose();
        Con.Close();
        Con.Dispose();
    }


 }

此代码工作正常，将值插入两个不同的表，现在我的问题是I have two select statement of two different table in one stored procedure how to return the values in the function??是否应该使用object返回？如果是这样，如何创建object。任何帮助表示赞赏

您可以将DataTable形式的select语句结果集合并到Dataset。

以下代码段使用SqlDataAdapter＆amp; DataSet，在适用的地方更改值

C＃代码

System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlConnection("<SQL Server Connection string>");
System.Data.SqlClient.SqlDataAdapter adptr = new System.Data.SqlClient.SqlDataAdapter("exec <Stored Proc name>", conn);
System.Data.DataSet dataset = new System.Data.DataSet();
adptr.Fill(dataset);

System.Data.DataTable table = new System.Data.DataTable();
table = dataset.Tables[0];
//do something for table-1

table = dataset.Tables[1];
//do something for table-2

返回数据访问对象中存储过程的两个select语句中的值
