Question

我有以下查询错误输出操作数类型冲突：时间与浮动

不兼容

select (sum(ReceivedContacts) * CONVERT(TIME, DATEADD(s, SUM(( DATEPART(hh, AverageWaitTime) * 3600 ) + ( DATEPART(mi, AverageWaitTime) * 60 ) + DATEPART(ss, AverageWaitTime)), 0)) / Sum(ReceivedContacts)) AS total_time
from TelephonyStats

已接收联系人的数据类型为float，AverageWaitTime为时间

请帮忙

将CONVERT移至TIME并整理其余括号，它应该可以正常工作。请尝试以下查询：

SELECT 
        SUM(ReceivedContacts) * ( 
           SUM ( 
                  ( DATEPART(hh, AverageWaitTime) * 3600 ) + 
                  ( DATEPART(mi, AverageWaitTime) * 60 ) + 
                  ( DATEPART(ss, AverageWaitTime) )
               ) / SUM(ReceivedContacts)
        ) AS total_time
FROM TelephonyStats

操作数类型冲突：时间与浮动计算不兼容
