使用 CTE 连接两个表

Question

我有两个查询返回以下输出：T1 和 T2

现在我想在 T1.CMonth 和 T2.DueMonth 字段中加入这两个表。

最终输出应如 png 所示。

T1 的查询：

SELECT WorkManagementAsset.AssetCategory, CONVERT(CHAR(4), WorkItem.CompleteDate, 100) + CONVERT(CHAR(4), WorkItem.CompleteDate, 120) AS CMonth, COUNT(CONVERT(CHAR(4), WorkItem.CompleteDate, 100) + CONVERT(CHAR(4), WorkItem.CompleteDate, 120)) 作为 Total_Complete FROM WorkManagementAsset INNER JOIN WorkOrder ON WorkManagementAsset.Oid = WorkOrder.Asset INNER JOIN WorkItem ON WorkOrder.Oid = WorkItem.WorkOrder INNER JOIN InspectionDefectItem ON WorkItem.DefectItem = InspectionDefectItem.Oid AND WorkItem.Oid = InspectionDefectItem.WorkItem WHERE（不是（InspectionDefectItem.DefectGroupName LIKE N'Re%'）） 按 WorkManagementAsset.AssetCategory 分组，CONVERT(CHAR(4)，WorkItem.CompleteDate，100) + CONVERT(CHAR(4)，WorkItem.CompleteDate，120) HAVING (WorkManagementAsset.AssetCategory = N'sealedroads') AND (NOT (CONVERT(CHAR(4), WorkItem.CompleteDate, 100) + CONVERT(CHAR(4), WorkItem.CompleteDate, 120) IS NULL))

T2 的查询：

选择 WorkManagementAsset.AssetCategory, CONVERT(CHAR(4), WorkItem.DueDate, 100) + CONVERT(CHAR(4), WorkItem.DueDate, 120) AS 到期月， COUNT(CONVERT(CHAR(4), WorkItem.DueDate, 100) + CONVERT(CHAR(4), WorkItem.DueDate, 120)) AS Total_DUE FROM WorkManagementAsset INNER JOIN WorkOrder ON WorkManagementAsset.Oid = WorkOrder.Asset INNER JOIN WorkItem ON WorkOrder.Oid = WorkItem.WorkOrder INNER JOIN InspectionDefectItem ON WorkItem.DefectItem = InspectionDefectItem.Oid AND WorkItem.Oid = InspectionDefectItem.WorkItem WHERE (NOT (InspectionDefectItem.DefectGroupName LIKE N'Re%')) GROUP BY WorkManagementAsset.AssetCategory, CONVERT(CHAR(4), WorkItem.DueDate, 100) + CONVERT(CHAR(4), WorkItem.DueDate, 120) HAVING
（WorkManagementAsset.AssetCategory = N'sealedroads'）和 (CONVERT(CHAR(4), WorkItem.DueDate, 100) + CONVERT(CHAR(4), WorkItem.DueDate, 120) '0')

任何帮助将不胜感激。 谢谢

这个

WITH T1 AS
(
  SELECT 
    WorkManagementAsset.AssetCategory, 
    CONVERT(CHAR(4), WorkItem.CompleteDate, 100) + CONVERT(CHAR(4), WorkItem.CompleteDate, 120) AS CMonth, 
    COUNT(CONVERT(CHAR(4), WorkItem.CompleteDate, 100) + CONVERT(CHAR(4), WorkItem.CompleteDate, 120)) AS Total_Complete
  FROM WorkManagementAsset 
  INNER JOIN WorkOrder 
    ON WorkManagementAsset.Oid = WorkOrder.Asset 
  INNER JOIN WorkItem 
    ON WorkOrder.Oid = WorkItem.WorkOrder 
  INNER JOIN InspectionDefectItem 
    ON WorkItem.DefectItem = InspectionDefectItem.Oid AND WorkItem.Oid = InspectionDefectItem.WorkItem 
  WHERE (NOT (InspectionDefectItem.DefectGroupName LIKE N'Re%')) 
  GROUP BY 
    WorkManagementAsset.AssetCategory, 
    CONVERT(CHAR(4), WorkItem.CompleteDate, 100) + CONVERT(CHAR(4), WorkItem.CompleteDate, 120) 
  HAVING (WorkManagementAsset.AssetCategory = N'sealedroads') 
  AND (NOT (CONVERT(CHAR(4), WorkItem.CompleteDate, 100) + CONVERT(CHAR(4), WorkItem.CompleteDate, 120) IS NULL))
),
T2 AS
(
  SELECT 
    WorkManagementAsset.AssetCategory, 
    CONVERT(CHAR(4), WorkItem.DueDate, 100) + CONVERT(CHAR(4), WorkItem.DueDate, 120) AS DueMonth, 
    COUNT(CONVERT(CHAR(4), WorkItem.DueDate, 100) + CONVERT(CHAR(4), WorkItem.DueDate, 120)) AS Total_DUE 
  FROM WorkManagementAsset 
  INNER JOIN WorkOrder 
    ON WorkManagementAsset.Oid = WorkOrder.Asset 
  INNER JOIN WorkItem 
    ON WorkOrder.Oid = WorkItem.WorkOrder 
  INNER JOIN InspectionDefectItem 
    ON WorkItem.DefectItem = InspectionDefectItem.Oid 
    AND WorkItem.Oid = InspectionDefectItem.WorkItem 
  WHERE (NOT (InspectionDefectItem.DefectGroupName LIKE N'Re%')) 
  GROUP BY WorkManagementAsset.AssetCategory, 
  CONVERT(CHAR(4), WorkItem.DueDate, 100) + CONVERT(CHAR(4), WorkItem.DueDate, 120) 
  HAVING (WorkManagementAsset.AssetCategory = N'sealedroads') 
  AND (CONVERT(CHAR(4), WorkItem.DueDate, 100) + CONVERT(CHAR(4), WorkItem.DueDate, 120) <> '0')
)
SELECT *
FROM T1 
INNER JOIN T2 ON T1.CMonth = T2.DueMonth;

请注意，由于多种原因，这是一个非常低效的查询。
