Answer 1

是不是很简单：

Select 
    ROW_NUMBER() OVER (ORDER BY CASE 
                                   WHEN VGID = 165 then 1    
                                   WHEN VGID = 158 then 2 
                                   WHEN VGID = 159 then 3 
                                   WHEN VGID = 157 then 4 
                                   WHEN VGID = 156 then 5 
                                END) AS RowNumber
    , * 
    from T_EMS_VGDM_RULEMST 
    where VGID in (156,157,158,159,165) 
    ORDER BY CASE 
     WHEN VGID = 165 then 1    
     WHEN VGID = 158 then 2 
     WHEN VGID = 159 then 3 
     WHEN VGID = 157 then 4 
     WHEN VGID = 156 then 5 
    END

Answer 2

    Select 

ROW_NUMBER() OVER (ORDER BY vgid desc) AS RowNumber, 
 * from T_EMS_VGDM_RULEMST where VGID in (156,157,158,159,165) 
ORDER BY CASE 
 WHEN VGID = 165 then 1    
 WHEN VGID = 158 then 2 
 WHEN VGID = 159 then 3 
 WHEN VGID = 157 then 4 
 WHEN VGID = 156 then 5 
END
