将案例语句转换为列标题

Question

我不是SQL的专家。我有以下查询，我想要做的是将状态作为单个列移动并计算不同的actionid。

查询：

SELECT
CONVERT (Date,[ActionTime],103) AS DATE,
COUNT(DISTINCT ActionID) AS Actions,
VehicleID AS VehicleID,
DriverID AS DriverID,
     CASE 
     WHEN ActionTypeID = 7 THEN 'Not Suitable'
     WHEN ActionTypeID = 8 THEN 'Job Acknowledged'
     WHEN ActionTypeID = 9 THEN 'Job Accepted'
     WHEN ActionTypeID = 10 THEN 'Job Rejected'
     WHEN ActionTypeID = 12 THEN 'Job Recall'
     WHEN ActionTypeID = 66 THEN 'Child Fleet Logon'
     WHEN ActionTypeID = 67 THEN 'Child Fleet Logoff'
     ELSE '' END AS Status

FROM [TaxiHistory].[dbo].[Actions]
WHERE actiontime between '2016-02-01 00:00:00' AND '2016-02-02 23:59:59'
  AND ActiontypeID IN (7,8,9,10,12,66,67)

  GROUP BY CONVERT (Date,[ActionTime],103),
CASE 
     WHEN ActionTypeID = 7 THEN 'Not Suitable'
     WHEN ActionTypeID = 8 THEN 'Job Acknowledged'
     WHEN ActionTypeID = 9 THEN 'Job Accepted'
     WHEN ActionTypeID = 10 THEN 'Job Rejected'
     WHEN ActionTypeID = 12 THEN 'Job Recall'
     WHEN ActionTypeID = 66 THEN 'Child Fleet Logon'
     WHEN ActionTypeID = 67 THEN 'Child Fleet Logoff'
     ELSE ''  END,
VehicleID,
DriverID

Answer 1

select
    CONVERT (Date,[ActionTime],103) AS DATE,
    COUNT(DISTINCT ActionID) AS Actions,
    VehicleID AS VehicleID,
    DriverID AS DriverID,
    [7] 'Not Suitable',
    [8] 'Job Acknowleged',
    [9] 'Job Accepted',
    [10] 'Job Rejected',
    [12] 'Job Recall',
    [66] 'Child Freet Logon',
    [67] 'Child Fleet Logoff'   
(
    select ActionTime, VehicleId, DriverId, ActionTypeId, count(*) as TotalType
    FROM [TaxiHistory].[dbo].[Actions]
    WHERE actiontime between '2016-02-01 00:00:00' AND '2016-02-02 23:59:59'
      AND ActiontypeID IN (7,8,9,10,12,66,67)
    group by ActionTime, VehicleId, DriverId, ActionTypeId
pivot(sum(TotalType) for ActionTypeId in ([7],[8],[9],[10],[12], [66], [67])) 
) p

内部查询是基本查询，它获取每个ActionTime，Vehicle，Deiver和ActionType的Actions数。 PIVOT的结尾基本上表示对于列出的每个ActionTypeId，总结TotalType并在结果集中放入一个名为ActionTypeId值的列。这个结果集（查询中的p）是外部选择的输入，它接受列并为其添加各种名称。

我认为这是你正在尝试做的事情。

SELECT  CONVERT (DATE,[ActionTime],103) AS [Date],
        VehicleID AS VehicleID,
        DriverID AS DriverID,
        COUNT(CASE WHEN ActionTypeID = 7 THEN 1 END)  AS [Not Suitable],
        COUNT(CASE WHEN ActionTypeID = 8 THEN 1 END)  AS [Job Acknowledged],
        COUNT(CASE WHEN ActionTypeID = 9 THEN 1 END)  AS [Job Accepted],
        COUNT(CASE WHEN ActionTypeID = 10 THEN 1 END) AS [Job Rejected],
        COUNT(CASE WHEN ActionTypeID = 12 THEN 1 END) AS [Job Recall],
        COUNT(CASE WHEN ActionTypeID = 66 THEN 1 END) AS [Child Fleet Logon],
        COUNT(CASE WHEN ActionTypeID = 67 THEN 1 END) AS [Child Fleet Logoff]
FROM    [TaxiHistory].[dbo].[Actions]
WHERE   actiontime BETWEEN '2016-02-01 00:00:00'
                   AND     '2016-02-02 23:59:59'
        AND ActiontypeID IN (7,8,9,10,12,66,67)
GROUP BY CONVERT (DATE,[ActionTime],103),
        VehicleID,
        DriverID
