Question

我有一组数据，其中有六行小数，我想总结一下，它们是按帐户代码分组的。我有一个存储的proc，它是将数据带入实体的视图，但我不确定按照我的逻辑。

List<NominalSums> _nominalSums = new List<NominalSums>()
foreach (var items in _nominalData)
{
      using (var db = new ConsolidatedSage50Entities())
      {
                    var accRef = items.ACCOUNT_REF;

                    var clientIdParameter1 = new SqlParameter("@AccountRef", SqlDbType.NVarChar);
                    clientIdParameter1.Value = accRef;

                    var clientIdParameter2 = new SqlParameter("@SortOrder", SqlDbType.NVarChar);
                    clientIdParameter2.Value = 321;

                    var clientIdParameter3 = new SqlParameter("@CATEGORY", SqlDbType.BigInt);
                    clientIdParameter3.Value = 5;

                    var result = db.Database.SqlQuery<sp_fuel_sumbalances_Result>("sumbalances @AccountRef, @SortOrder, @CATEGORY", new object[] { clientIdParameter1, clientIdParameter2, clientIdParameter3 }).ToList();


                    foreach (var groupData in result)
                    {       
                        _nominalSums.Add(new NominalSums()
                        {
                            ACCOUNT_REF = groupData.ACCOUNT_REF,
                            BALANCE_MTH11 = groupData.BALANCE_MTH1,
                            SortOrder =(int) groupData.SORT_ORDER,
                            Category = (int) groupData.CATEGORY

                        });
                    }
                }

            }
            return _nominalSums;
        }

上面的代码会为每个结果打印一行新的一行，因为我只想一行结合存储的proc的结果总数，可以有人在这里向我指出正确的方向。

编辑2 我的主要问题是因为我的存储过程如下所示，我将如何对该存储过程进行组和运算呢？因为我只想从主查询中返回一行，而对于一组特定的critera，该行有六行。

ALTER PROCEDURE [dbo].[sumbalances] 
    -- Add the parameters for the stored procedure here
    @AccountRef varchar(500),
    @SortOrder int,
    @CATEGORY int
    as
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    SELECT        NOMINAL_LEDGER.ACCOUNT_REF, NOMINAL_LEDGER.NAME, NOMINAL_LEDGER.ACCOUNT_TYPE, NOMINAL_LEDGER.BALANCE, NOMINAL_LEDGER.QUICK_RATIO, NOMINAL_LEDGER.SOFA_ID, 
                         NOMINAL_LEDGER.PRIOR_YR_MTH1, NOMINAL_LEDGER.PRIOR_YR_MTH2, NOMINAL_LEDGER.PRIOR_YR_MTH3, NOMINAL_LEDGER.PRIOR_YR_MTH4, NOMINAL_LEDGER.PRIOR_YR_MTH5, 
                         NOMINAL_LEDGER.PRIOR_YR_MTH6, NOMINAL_LEDGER.PRIOR_YR_MTH7, NOMINAL_LEDGER.PRIOR_YR_MTH8, NOMINAL_LEDGER.PRIOR_YR_MTH9, NOMINAL_LEDGER.PRIOR_YR_MTH10, 
                         NOMINAL_LEDGER.PRIOR_YR_MTH11, NOMINAL_LEDGER.PRIOR_YR_MTH12, NOMINAL_LEDGER.PRIOR_YR2_MTH1, NOMINAL_LEDGER.PRIOR_YR2_MTH2, NOMINAL_LEDGER.PRIOR_YR2_MTH3,
FROM            CATEGORY left JOIN
                         NOMINAL_LEDGER ON CATEGORY.CompanyID = NOMINAL_LEDGER.CompanyID
                         WHERE ACCOUNT_REF=@AccountRef AND SORT_ORDER=@SortOrder and CATEGORY=@CATEGORY

END

这是一些sudo代码，我不确定您要总结哪些字段，我想您是用accountID说的。因此，您需要做两件事才能使此工作通过accountID取得总和：

将SUM（FieldsYouWantToSumUpByAccountID）作为FieldNameYouWantToCallIt添加到您的选择中
在我添加的“分组依据”中，您将对您希望在选择列表中进行的所有字段进行分组（未进行汇总）。 SO ID，Ref等。

t

SELECT   SUM(FieldYouWantSummed),     NOMINAL_LEDGER.ACCOUNT_REF, NOMINAL_LEDGER.NAME, NOMINAL_LEDGER.ACCOUNT_TYPE, NOMINAL_LEDGER.BALANCE, NOMINAL_LEDGER.QUICK_RATIO, NOMINAL_LEDGER.SOFA_ID, 
                             NOMINAL_LEDGER.PRIOR_YR_MTH1, NOMINAL_LEDGER.PRIOR_YR_MTH2, NOMINAL_LEDGER.PRIOR_YR_MTH3, NOMINAL_LEDGER.PRIOR_YR_MTH4, NOMINAL_LEDGER.PRIOR_YR_MTH5, 
                             NOMINAL_LEDGER.PRIOR_YR_MTH6, NOMINAL_LEDGER.PRIOR_YR_MTH7, NOMINAL_LEDGER.PRIOR_YR_MTH8, NOMINAL_LEDGER.PRIOR_YR_MTH9, NOMINAL_LEDGER.PRIOR_YR_MTH10, 
                             NOMINAL_LEDGER.PRIOR_YR_MTH11, NOMINAL_LEDGER.PRIOR_YR_MTH12, NOMINAL_LEDGER.PRIOR_YR2_MTH1, NOMINAL_LEDGER.PRIOR_YR2_MTH2, NOMINAL_LEDGER.PRIOR_YR2_MTH3,
    FROM            CATEGORY 
    LEFT JOIN NOMINAL_LEDGER ON CATEGORY.CompanyID = NOMINAL_LEDGER.CompanyID
    WHERE ACCOUNT_REF=@AccountRef 
    AND SORT_ORDER=@SortOrder 
    AND CATEGORY=@CATEGORY
    GROUP BY Account_REF (AND ALL other fields that you want duplicated)

如果您可以提供要选择的字段列表和要累加的字段，如果不清楚，我可以为您更新上述声明。

将结果集汇总为一行
