正如您可能首先注意到的那样，我有fcst的长列表，因为：
表1是从系统自动生成的
表2由用户输入，表2的表结构是
| Date | fsct01 | fcst02 ........... fcst0N | -------------------------------------------------- | date | int | int ............. int |
并在每次更新时垂直填充。
现在，table1和table2的关系就像在table1的每个记录中一样，需要table2的一列。第1行与fcst01配对，第2行与fcst02配对，依此类推，使用键row_date = date。
table1在一个日期（66行）下有多个行，table2每个日期只有1行。
week aps sfcst ...
27 28 568 ...
27 26 889 ...
28 28 284 ...
28 37 948 ...
我希望按week对此进行分组，但似乎fsct正在弄乱它，因为它需要包含在分组中。
我希望它是......
week aps sfcst ...
27 sum(aps) [sum of all fcst within the week] ...
28 sum(aps) [sum of all fcst within the week] ...
29 sum(aps) [sum of all fcst within the week] ...
30 sum(aps) [sum of all fcst within the week] ...
希望我有意义， 可能有什么可以解决这个问题？

很抱歉，但你的问题并不是那么清楚。您能否通过以下链接重新发帖：
Short, Self Contained, Correct (Compilable), Example
还要给你一些思考的食物，你可以看看选项：
答案 1 :(得分：0)
终于找到了正确的逻辑。只需将table2分组并将其与table1 ON table1.week = table2.week。
连接即可以下是代码：
