Msg 245，Level 16，State 1，Line 1
  将nvarchar值'50310H'转换为数据类型int时，转换失败。

Answer 1

我的钱是加入或where子句作为你的问题。我会提供可能有用的调试建议，因为我无法发表评论。 识别：如果您知道50310H是什么，如果是货号或其他什么，您可以更快地找到它并比较两个表中的字段。另一个选择是只比较表属性并查看字段是什么。可能有两个表正在尝试匹配的值，但一个是int，一个是nvarchar。 要解决：最终的解决方案是 cast（whateverintfield as nvarchar） 一旦你确定了罪犯，就阻止它与你争论。祝好运。
