Question

我有以下存储过程：

ALTER PROCEDURE [dbo].[spRptFundsTransferSchoolProfileSelect]          
(          
    @SessionID int ,      
    @DateRangeStart DateTime,       
    @DateRangeEnd DateTime       
)          
AS          
BEGIN        
 SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED     


    --set @SessionID = 1175      

    SELECT  tss.school_id,           
            ts.school_code,          
            tss.id,           
            ts.school_name,           
            ta.address,           
            ta.city,           
            ta.zip,            

    FROM T_School ts           

    Execute [dbo].[spRptFundsTransferPaymentSummarySelect]     @SessionID ,      
                                                               @DateRangeStart ,       
                                                               @DateRangeEnd       
END

以及关于返回输出的以下模型：

namespace FundTr.de
{
    public class FundTrans : ModelBase
    {
        public string school_name { get; set; }

        public string school_code { get; set; }

        public int school_id { get; set; }

        public long id { get; set; }

        public string address { get; set; }

        public string city { get; set; }

        public string zip { get; set; }

        public string Date_Added { get; set; }//from dbo.spRptFundsTransferPaymentSummarySelect procedure

    }
}

contolller：

public ActionResult GetFundTransferReportTemplate(DateTime DateRangeStart, DateTime DateRangeEnd)
        {
            return SmartJson(ReportService.GetFundTransferReportTemplate(DateRangeStart, DateRangeEnd));

        }

服务：

 public static FundTransferReportTemplate GetFundTransferReportTemplate(DateTime DateRangeStart, DateTime DateRangeEnd)
        {
            long SessionID = 1175;// SmartState.session.schoolSession.SessionId;
            var repo = GetRepository<FundTransferReportTemplate>();
            var da = repo.GetSingleObject("spRptFundsTransferSchoolProfileSelect", new { DateRangeStart, DateRangeEnd, SessionID });
            return da;

        }

当我点击控制器时，除了最后一个＆＃34; Date_Added＆＃34;（来自程序dbo.spRptFundsTransferPaymentSummarySelect的此字段），我得到所有值。我的意思是说我没有获得dbo.spRptFundsTransferPaymentSummarySelect的输出值。我可以得到访问在主程序中执行的程序的输出值？

SP从上到下执行，从某种意义上说，它将执行SELECT语句，然后执行SP spRptFundsTransferPaymentSummarySelect 。假设SP spRptFundsTransferPaymentSummarySelect 返回单个值，即 date_added

您需要先调用 spRptFundsTransferPaymentSummarySelect 并将值存储在变量@Date_Added中，然后在SELECT语句中使用它。

ALTER PROCEDURE [dbo].[spRptFundsTransferSchoolProfileSelect]
(
    @SessionID int,
    @DateRangeStart DateTime,
    @DateRangeEnd DateTime
)
AS
BEGIN
    SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
    DECLARE @Date_Added DateTime

    Execute @Date_Added = [dbo].[spRptFundsTransferPaymentSummarySelect] @SessionID,
                                                                @DateRangeStart,
                                                                @DateRangeEnd

    --set @SessionID = 1175

    SELECT tss.school_id,
        ts.school_code,
        ts.id,
        ts.school_name,
        ta.address,
        ta.city,
        ta.zip,
        @Date_Added AS Date_Added
    FROM T_School ts
END

如何从正在另一个内部执行的存储过程返回或获取输出值
