我一个月前创建了此脚本，以一种固定的格式提取数据，以供另一个脚本中使用，以重新导入到另一个表中。

它对我来说非常完美，但是现在我得到了模棱两可的错误，我什至不明白为什么！服务器上似乎没有任何更改。我确实更改了localadmin，但这又回到了原来的状态！

我建议您不要对列别名使用a，b等随机字母。使用表缩写，例如TransactionType tt和TransactionHistory th。

按照书面规定，您的查询将完全不会运行。造成列错误的常见原因是列不合格。但是所有人都合格。另一方面，此表达式：

sum (a.Quantity  (Case when b.TransactionTypeID =15 then 1 Else 0 end ))

完全无效。表达式之间也许应该有一个*。

我的猜测是，在移动代码提问时，您限定了一个或多个在原始查询中不合格的列名。

找不到列“ a”或用户定义的函数或聚合“ a.Quantity”，或者名称不明确
