    SELECT distinct
     CM_NAME, 
     Booking_Date,
     sum(DogRevenue) as TTL_DogREV,
     sum(Room_Revenue) as TTL_ROOM,
     sum(Car_Revenue) AS TTL_CAR,

     sum(Dog_Rev + Room + Car + Activity) as 
     TTL_BOOK

     from

       (SELECT         
            internalagentname as CM_NAME,
            resvCode AS Booking_Number,
            transactionDate AS "Transaction_Date",
            CONVERT(VARCHAR(10), initialbookingdate, 101) as Booking_Date

由于某种原因，我在尝试将预订日期转换为MM / DD / YYYY时仍然出现错误，因为它目前采用以下格式：DD-MON-YYYY（01-FEB-2018）

我不断表达缺失错误

Answer 1

在转换为varchar（10）之前先转换为日期，如下所示：

选择转换（varchar（10），强制转换（＆＃39; 01-FEB-2018＆＃39;作为日期），101）
