显示“空”

Question

我在SQL Express 2016中遇到问题。 我在一个表中有打印跟踪数据，显示了：

1. 设备序列号（DeviceModel）
2. 部门成本代码（UserCostCode）
3. 用户名（UserLogon）
4. 作业打印时间（StartDateTime）
5. 页数（Tr​​ackingPageCount）
6. 如果打印是彩色的（JobIsColour）
7. 如果打印是双面打印（JobIsDuplex）
8. 相关工作成本（价格）

现在，我正在尝试获取一个结果表，显示按设备序列号分组打印的总页数，然后是部门成本代码，最后是用户名。

输出理想情况如下：

Device Serial   Cost Code  User Name      ColSpx   ColDpx   MonSpx   MonDpx   Price

CH238713498     2665473    Angela Rippon   43       22        245     566      £ 20
CH238713498     2665473    Warwick Davis    2        0       1000     230      £ 30
CH238713498     2623379    Carl Carlson    53        0       2145    1566      £ 55
CH238713498     2664443    Warwick Davis    2        0       1000     230      £ 30

我一直在使用的查询（并且没有成功更改）是：

DECLARE @ColourSimplex bigint SELECT TrackingPageCount
FROM TrackingTable    
WHERE JobIsColor = 1 AND JobIsDuplex = 0 AND JobType < 4 AND TrackingState = 2 AND (UserLogon NOT LIKE '%name%' AND UserLogon NOT LIKE '%name%' AND UserLogon NOT LIKE '%SYSTEM%') AND TrackingPageCount > 0

DECLARE @ColourDuplex bigint SELECT TrackingPageCount
FROM TrackingTable
WHERE JobIsColor = 1 AND JobIsDuplex = 1 AND JobType < 4 AND TrackingState = 2 AND (UserLogon NOT LIKE '%name%' AND UserLogon NOT LIKE '%name%' AND UserLogon NOT LIKE '%SYSTEM%') AND TrackingPageCount > 0

DECLARE @MonoSimplex bigint SELECT TrackingPageCount
FROM TrackingTable    
WHERE JobIsColor = 0 AND JobIsDuplex = 0 AND JobType < 4 AND TrackingState = 2 AND (UserLogon NOT LIKE '%name%' AND UserLogon NOT LIKE '%name%' AND UserLogon NOT LIKE '%SYSTEM%') AND TrackingPageCount > 0

DECLARE @MonoDuplex bigint SELECT TrackingPageCount
FROM TrackingTable
WHERE JobIsColor = 0 AND JobIsDuplex = 1 AND JobType < 4 AND TrackingState = 2 AND (UserLogon NOT LIKE '%name%' AND UserLogon NOT LIKE '%name%' AND UserLogon NOT LIKE '%SYSTEM%') AND TrackingPageCount > 0

SELECT  DeviceModel,
        UserCostCode,
        UserLogon,
        SUM(@ColourSimplex) AS 'Colour Simplex',
        SUM(@ColourDuplex) AS 'Colour Duplex',
        SUM(@MonoSimplex) AS 'Mono Simplex',
        SUM(@MonoDuplex) AS 'Mono Duplex',
        SUM(Price) AS 'Cost'

FROM TrackingTable

WHERE   StartDateTime BETWEEN '2017-05-31 23:59:00' AND '2017-08-31 23:59:00'

GROUP BY DeviceModel,
        UserCostCode,
        UserLogon

ORDER BY DeviceModel, UserCostCode, UserLogon

以下是我得到的结果示例：

L7L3Y01090  100951      MARINA SIRBU            NULL    NULL    NULL    NULL    0.84
L7L3Y01090  A01016-DE06 MADELEINE MCALLISTER    NULL    NULL    NULL    NULL    0.168
L7L3Y01090  A02026-DE06 DANIEL POULTER          NULL    NULL    NULL    NULL    0.448

如何解决这个问题的任何帮助都将非常感激。

SELECT  DeviceModel,
        UserCostCode,
        UserLogon,
        SUM(CASE WHEN JobIsColor = 1 AND JobIsDuplex = 0 AND JobType < 4 AND TrackingState = 2 AND (UserLogon NOT LIKE '%name%' AND UserLogon NOT LIKE '%name%' AND UserLogon NOT LIKE '%SYSTEM%') AND TrackingPageCount > 0 THEN TrackingPageCount  ELSE 0 END) AS 'Colour Simplex',
        SUM(Price) AS 'Cost'

FROM TrackingTable

WHERE   StartDateTime BETWEEN '2017-05-31 23:59:00' AND '2017-08-31 23:59:00'

GROUP BY DeviceModel,
        UserCostCode,
        UserLogon

ORDER BY DeviceModel, UserCostCode, UserLogon
