SQL查询返回正确的行号

Question

以下查询返回RowNumber_ps = 101，RowNumber_ps是行计数，但是它应该返回RowNumber_ps = 1，因为我只有一行包含0个文档。任何人都可以告诉我RowNumber_ps没有返回1的查询有什么问题吗？

SELECT *
FROM 
    (SELECT 
         ROW_NUMBER() OVER(Order By ParentID) AS RowNumber_ps,
         UPPER(HostApplicationLocalData.ParentID) asParentID,
         COUNT(Document.ID) AS Documents 
     FROM 
         HostApplicationLocalData 
     LEFT OUTER JOIN 
         Document ON HostApplicationLocalData.ID = Document.HostApplicationLocalData_ID
     WHERE 
         HostApplicationLocalData.TransactionType_ID = 1
         AND HostApplicationLocalData.Company_ID = 9000
     GROUP BY 
         HostApplicationLocalData.ParentID) q
WHERE
     Documents = '0'

Answer 1

您应该在子查询中放置'WHERE'条件。
