Tsql 使用CTE连接两个表

我有两个查询返回以下输出：T1和T2

现在，我想连接T1.CMonth和T2.DueMonth字段上的两个表

最终输出应如png中所示

T1的查询：

选择WorkManagementAsset.AssetCategory、CONVERTCHAR4、WorkItem.CompleteDate、100+CONVERTCHAR4、WorkItem.CompleteDate、120作为cm月， COUNTCONVERTCHAR4，WorkItem.CompleteDate，100+CONVERTCHAR4，WorkItem.CompleteDate，总计120 从WorkManagementAsset内部联接 WorkManagementAsset.Oid上的WorkOrder=WorkOrder.Asset内部联接 WorkOrder.Oid上的WorkItem=WorkItem.WorkOrder内部联接 WorkItem.DefectItem上的InspectionDefectItem=InspectionDefectItem.Oid和WorkItem.Oid=InspectionDefectItem.WorkItem 其中不包括InspectionDefectItem.DefectGroupName，如N'Re%' 按WorkManagementAsset.AssetCategory分组，CONVERTCHAR4，WorkItem.CompleteDate，100+CONVERTCHAR4，WorkItem.CompleteDate，120 具有WorkManagementAsset.AssetCategory=N'SealedLoads'且不具有CONVERTCHAR4、WorkItem.CompleteDate、100+CONVERTCHAR4， WorkItem.CompleteDate，120为空

T2的查询：

选择WorkManagementAsset.AssetCategory，CONVERTCHAR4， WorkItem.DueDate，100+CONVERTCHAR4，WorkItem.DueDate，120 AS 上个月， COUNTCONVERTCHAR4，WorkItem.DueDate，100+CONVERTCHAR4，WorkItem.DueDate，120作为WorkManagementAsset内部联接到期的总金额 WorkManagementAsset.Oid上的WorkOrder=WorkOrder.Asset内部联接 WorkOrder.Oid上的WorkItem=WorkItem.WorkOrder内部联接 WorkItem.DefectItem上的InspectionDefectItem=InspectionDefectItem.Oid和WorkItem.Oid= InspectionDefectItem.WorkItem，其中不包括 InspectionDefectItem.DefectGroupName类似于N'Re%'分组依据 WorkManagementAsset.AssetCategory，CONVERTCHAR4，WorkItem.DueDate， 100+CONVERTCHAR4，WorkItem.DueDate，120具有 WorkManagementAsset.AssetCategory=N'sealedroads'和 CONVERTCHAR4，WorkItem.DueDate，100+CONVERTCHAR4， WorkItem.DueDate，120“0”

任何帮助都将不胜感激。 谢谢

请注意，这是一个效率极低的查询，原因有很多

感谢您的快速回复，查询生成了所需的输出。您能否指出效率低下的原因，以便我可以提高我的知识和查询效率well@FazalT像AND NOT CONVERTCHAR4、WorkItem.CompleteDate、100+CONVERTCHAR4、WorkItem.CompleteDate、120为NULL这样的奇怪信息也没有帮助。这与WorkItem.CompleteDate不为NULL有点类似吗？
