每个商店都有自己的数据库（我同意这是不好的做法），我需要从符合特定条件的所有个人数据库中获取数据。到目前为止，我已经想出了这个，但是我得到了错误

  

Msg 102，Level 15，State 1，Line 81
  '）'附近的语法不正确。

我认为这将展示我需要实现的目标，动态SQL是执行此任务的最佳方式吗？如果是这样，我该怎么做才能消除我的错误。如果没有，那么更高级的SQL用户可以提供什么想法/想法/重写。

而不是等等，你可以用一个更新语句来做。

 insert into #FullOnFrontalData 
     select Sinf.storeid, tab, fod, lott, 1 from (
     select storeid, sum(tobaccosales) tab ,  sum(foodsales) fod, sum(lotterysales)  lott
     from #storeA 
     group by  storeid
     union all 
      select storeid, sum(tobaccosales) ,  sum(foodsales), sum(lotterysales) 
     from #storeB 
      group by  storeid
      union all 
      select storeid, sum(tobaccosales) ,  sum(foodsales), sum(lotterysales) 
     from #storeC
      group by  storeid
      union all 
      select storeid, sum(tobaccosales) ,  sum(foodsales), sum(lotterysales) 
     from #storeD
