Answer 1

或者你可以PIVOT（假设你不需要动态）

示例

Select *
 From  (
        Select bdate
              ,B.*
         From  YourTable A
         Cross Apply ( values (replace(th_name,' ','')+'amt',amt)
                             ,(replace(th_name,' ','')+'NetSale',NetSale)
                             ,(replace(th_name,' ','')+'GST',GST)
                             ,(replace(th_name,' ','')+'Occupancy',Occupancy)
                     ) B(Item,Value)
       ) src
 Pivot (max(Value) for Item in ([Screen1amt],[Screen1NetSale],[Screen1GST],[Screen1Occupancy],[Screen2amt],[Screen2NetSale],[Screen2GST],[Screen2Occupancy],[Screen3amt],[Screen3NetSale],[Screen3GST],[Screen3Occupancy],[Screen4amt],[Screen4NetSale],[Screen4GST],[Screen4Occupancy]) ) pvt

<强>返回

我认为最简单的方法是条件聚合：

select bdate,
       max(case when th_name = 'Screen 1' then amt end) as screen1_amt,
       max(case when th_name = 'Screen 1' then netsale end) as screen1_netsale,
       max(case when th_name = 'Screen 1' then gst end) as screen1_gst,
       max(case when th_name = 'Screen 1' then occupancy end) as screen1_occupancy,
       max(case when th_name = 'Screen 2' then amt end) as screen2_amt,
       max(case when th_name = 'Screen 2' then netsale end) as screen2_netsale,
       max(case when th_name = 'Screen 2' then gst end) as screen2_gst,
       max(case when th_name = 'Screen 2' then occupancy end) as screen2_occupancy,
       . . .
from t
group by bdate;
