Answer 1

此选择查询是用SQL Server编写的。我不知道MySql的语法。您可以从此查询中获取LOGIC。试试这个，

select * 
    ,Datediff(dd,CreatedDate,ClosedDate) as D
    ,Datediff(hh,CreatedDate,ClosedDate) as H
    ,Case When Datediff(dd,CreatedDate,ClosedDate) > 0
            Then Datediff(hh,CreatedDate,ClosedDate) - (15 * Datediff(dd,CreatedDate,ClosedDate))
            else Datediff(hh,CreatedDate,ClosedDate)
    End [Time for closure]
