SQL枢轴导致from中的语法错误，我不知道为什么

Question

基本上，每当我尝试运行代码时，它都会在from中给出语法错误

SELECT * 
FROM
    (SELECT 
         Tbl_Derived_FMR_Codes.Reason, FMRList_tbl.FLEET, 
         FMRList_tbl.SUBFLEET, FMRList_tbl.[ACTIVITY DATE],   
         COUNT(FMRList_tbl.[FMR Reason Derived 1]) AS [CountOfFMR Reason Derived 1]
    FROM 
        Tbl_Derived_FMR_Codes 
    LEFT JOIN 
        FMRList_tbl ON Tbl_Derived_FMR_Codes.Reason = FMRList_tbl.[FMR Reason Derived 1]) AS Basedata
PIVOT(
  COUNT(ACTIVITY DATE)
  for FMRList_tbl in (FMRList_tbl.[ACTIVITY DATE])
) AS PivotTable
GROUP BY Tbl_Derived_FMR_Codes.Reason, FMRList_tbl.FLEET, FMRList_tbl.SUBFLEET, FMRList_tbl.[ACTIVITY DATE]
ORDER BY FMRList_tbl.[ACTIVITY DATE];
