存储过程返回到 C# .Net 中的 DataSet [英] Stored procedure return into DataSet in C# .Net

问题描述

我想从存储过程返回虚拟表，我想在 c# .net 的数据集中使用它.我的程序有点复杂，找不到如何返回表并将其设置在数据集中

I want to return virtual table from stored procedure and I want to use it in dataset in c# .net. My procedure is a little complex and can't find how to return a table and set it in a dataset

这是我修改的程序:

ALTER PROCEDURE [dbo].[Procedure1] 

    @Start datetime, 
    @Finish datetime,
    @TimeRange time
AS
BEGIN

    SET NOCOUNT ON;

    declare @TimeRanges as TABLE (SessionStart datetime, SessionEnd datetime);

     with TimeRanges as (
  select @Start as StartTime, @Start + @TimeRange as EndTime
  union all
  select StartTime + @TimeRange, EndTime + @TimeRange
    from TimeRanges
    where StartTime < @Finish )
  select StartTime, EndTime, Count( Test.ScenarioID ) as TotalPeaks
    from TimeRanges as TR left outer join
      dbo.Test as Test on TR.StartTime <= Test.SessionStartTime and Test.SessionCloseTime < TR.EndTime
    group by TR.StartTime, TR.EndTime   
END

推荐答案

试试这个

    DataSet ds = new DataSet("TimeRanges");
    using(SqlConnection conn = new SqlConnection("ConnectionString"))
    {               
            SqlCommand sqlComm = new SqlCommand("Procedure1", conn);               
            sqlComm.Parameters.AddWithValue("@Start", StartTime);
            sqlComm.Parameters.AddWithValue("@Finish", FinishTime);
            sqlComm.Parameters.AddWithValue("@TimeRange", TimeRange);

            sqlComm.CommandType = CommandType.StoredProcedure;

            SqlDataAdapter da = new SqlDataAdapter();
            da.SelectCommand = sqlComm;

            da.Fill(ds);
     }
