Question

我不敢相信我正在这样做，但是我坚持订购查询。

DECLARE @purseprioritylist VARCHAR(512) = 'ANT,ANT,BAT,BAT'

DECLARE @PriorityListTable TABLE
                           (
                                Id INT IDENTITY (1,1),
                                PurseType CHAR(3),
                                SecondaryPurseType BIT DEFAULT(0)
                           )     

INSERT INTO @PriorityListTable (PurseType)
    SELECT Value
    FROM STRING_SPLIT(@PursePriorityList, ',')

/*******************************************************

UPDATE @PriorityListTable 
SET SecondaryPurseType = 1 
WHERE ID IN (SELECT MAX(ID) AS MaxValue
             FROM @PriorityListTable pt
             GROUP BY pt.PurseType
             HAVING COUNT(pt.PurseType) > 1)

DECLARE @TV_MCCGROUPSWITHSECONDARYFLAG TABLE

INSERT INTO @tv_purselist (pursecandoid, slotid, pursename, pursetype, EffectiveDate, expdate, enddate, extensiondate)

SELECT  
    plt.*,
    pl.SlotId, pl.PurseName, pl.PurseType,
    mg.MCCGroup, pl.PurseCanDoId, pl.EffectiveDate, pl.EndDate,
    ISNULL(mg.IsSecondaryMCC, 0)

    @TV_PURSELIST pl
LEFT JOIN 
    @TV_MCCGROUPSWITHSECONDARYFLAG mg ON mg.PurseCanDoId = pl.PurseCanDoId  
INNER JOIN 
    @PriorityListTable plt ON plt.PurseType = pl.PurseType 
                           AND plt.SecondaryPurseType = mg.IsSecondaryMCC
ORDER BY 
    plt.Id, pl.PurseName, pl.EffectiveDate, pl.EndDate

问题是顺序不正确。

此查询返回...

我想要的是...

Answer 1

我认为这可以满足您的需求

order by 1, 3, 2

我建议使用列名，但我不知道它们是什么。

Answer 2

按以下顺序删除“ plt.Id”

        SELECT  
            plt.Id, plt.PurseType, plt.SecondaryPurseType
        ,   pl.SlotId
        ,   pl.PurseName
        ,   pl.PurseType
        ,   mg.MCCGroup 
        ,   pl.PurseCanDoId
        ,  pl.EffectiveDate
        ,  pl.EndDate
        ,  ISNULL(mg.IsSecondaryMCC, 0)
        FROM @TV_PURSELIST pl
        LEFT JOIN @TV_MCCGROUPSWITHSECONDARYFLAG mg on mg.PurseCanDoId = pl.PurseCanDoId  
        INNER JOIN @PriorityListTable plt on plt.PurseType = pl.PurseType and plt.SecondaryPurseType = mg.IsSecondaryMCC
        ORDER BY pl.PurseName, pl.EffectiveDate, pl.EndDate

结果：

您可以在SQL Order语句中进行分组吗（SQL Server）
