Question

情景：

我在存储过程中在SQL Server 2008 R2中使用tempTable（＃temporary table），我需要使用MIN(), MAX()和...之类的聚合函数来执行一系列计算临时表的列。

但是，临时表没有任何聚合函数。现在这个问题的最佳解决方案是什么？

请试试这个。我仍然对功能有点不清楚，但我最好的猜测是你在循环中有MIN（）所以它只返回一个值。我把它移到循环之外，所以最好的情况是它将检索集合的MIN（）。您需要稍微修改此查询以与查询合并。

IF OBJECT_ID(N'tempdb..#AccountingDocsDetail') > 0

IF OBJECT_ID(N'tempdb..#TempTableToday') > 0
