这是我的表:
ID Q1 Q2 Q3 Q4
----------------------------------------------------------------
20130712 NULL 728.63 NULL NULL
20130712 8881.55 9673.68 2629.566 6251.984
20130713 1813 1813 84.49 1728.51
20130714 3632.65 3632.65 1209.412 2423.238
20130714 70.758 2637.43 70.758 0
20130714 1601.578 3569.73 204.745 1396.833
20130714 728.63 728.63 0 728.63
20130714 1401.629 2251.39 94.418 1307.211
20130715 583.956 5089.19 583.956 0
20130805 6317.277 8958 2629.566 3687.711
我想要输出如下.(列可能会动态更改,需要按行计算Sum)
ID Q1 Q2 Q3 Q4 SUM(Q1:Q4)
---------------------------------------------------------------------------
20130712 NULL 728.63 NULL NULL 728.63
20130712 8881.55 9673.68 2629.566 6251.984 27436.78
20130713 1813 1813 …这是我在表格中的行:
Id | FromDate | ToDate | prod_Id ------|---------------------------|--------------------------|------- 1 | 2012-08-13 07:00:00.000 | 2012-08-14 18:59:00.000 | 10 1 | 2012-08-13 07:00:00.000 | 2012-08-15 18:59:00.000 | 10 1 | 2012-08-13 07:00:00.000 | 2012-08-16 18:59:00.000 | 10
我想得到如下结果:
Id | FromDate | ToDate | prod_Id ----|-----------------------------|---------------------------|--------- 1 | 2012-08-13 07:00:00.000 | 2012-08-16 18:59:00.000 | 10
怎么做？
