访问中的更新语句出错

Question

我是Access的新手，试图通过查看另一个访问表来更新其中一个访问表，但在我尝试执行下面的代码时遇到异常：

Update eb
SET 
    eb.LoadedDateTimeFrom = df.FromLoadedDateTimeD, 
    eb.LoadedDateTimeTo = df.ToLoadedDateTimeD
FROM 
    RhExceptionBuckets as eb 
INNER JOIN 
    ExceptionBucketTrancheDates as df 
    ON eb.TrancheTo = df.TrancheCode
    INNER JOIN 
        ExceptionBucketTrancheDates as df 
        ON eb.TrancheFrom = df.TrancheCode

有人可以帮助我。给出语法错误。
