Java 如何在子查询中添加排序依据或排序？

这是一个甚至包含分页的查询，我需要按照我指定的特定列进行排序

DECLARE @RowsPerPage INT = 100, @PageNumber INT =1 
SELECT DISTINCT * FROM 
(SELECT DISTINCT a.*,b.WorkflowId bWorkflowId,b.TRF_CompanyCoverage,
b.TRF_OrgID,b.TRF_Fundb_RepoNumber,b.TRF_WSC_PPI,b.TRF_BucketID,b.TRF_GAAPCode,b
.TRF_MarketCapUSD,b.TRF_OrgName,b.TRF_AutomationFlag,b.TRF_SmartPriority,b.TRF_I
ndustryName,b.TRF_ExchangeCountryCode,b.TRF_ExchangeCountryName,b.TRF_UserGroup,
Tasks.TaskId,Tasks.WorkflowId cworkFlowId,Tasks.TRFTaskId,Tasks.TaskName,
ROW_NUMBER() OVER (ORDER BY Tasks.WorkflowID) AS RowNum 
FROM  CCC_Filling_Metadata a,Fundamentals_Metadata b,Tasks 
WHERE a.WorkflowID=b.WorkflowID AND b.WorkflowID=Tasks.WorkflowID AND
Tasks.CreateDateTime >= '2015-01-01' 
AND  Tasks.CreateDateTime <= '2015-12-01' AND Tasks.Owner =  '0326271' AND 
Tasks.TaskStatus = 'open') AS SOD
WHERE SOD.RowNum BETWEEN ((@PageNumber-1)*@RowsPerPage)+1
AND @RowsPerPage*(@PageNumber) 
order by Tasks.TargetDate, Tasks.SmartPriority, Fundamentals_Metadata.TRF_MarketCapUSD desc

请帮助我了解如何在此查询中使用“Order by…”。

您的外部查询是：

选择DISTINCT*
从（…）到SOD
其中SOD.RowNum介于（（@PageNumber-1）*@RowsPerPage）+1和@RowsPerPage*（@PageNumber）之间
按Tasks.TargetDate、Tasks.SmartPriority、Fundamentals\u Metadata.TRF\u MarketCapUSD desc排序

因此，

任务

和

基础知识\u元数据

是未知的限定符。删除它们，因为您只有一个名为

SOD

的“视图”，所以不需要限定

---

当然，您需要将

Tasks.TargetDate

和

Tasks.SmartPriority

添加到内部查询中，以便对它们进行排序。

Msg 1033，级别15，状态1，第15行ORDER BY子句在视图、内联函数、派生表、子查询和公共表表达式中无效，除非还指定了TOP或FOR XML。当我被添加到课程的内部查询中时，会出现此错误。正如错误所说，您不能在内部查询中指定orderby，我没有告诉您这样做。我告诉过您从ORDERBY子句中删除限定符，并将缺少的列添加到内部查询的SELECT子句“以便它们可用于排序”。

ORDER BY items must appear in the select list if SELECT DISTINCT is specified.
