Question

这有什么问题？

如果我将查询剪切并粘贴到SSMS中的脚本中（并将其正确地格式化为查询），则代码将在SQL中执行而不会出现错误。所以问题出在答复中。

'yourordernumber'在hbm.xlm映射中定义为字符串，并作为varchar从SQL Server返回。

我想我还有两个问题。为什么错误异常消息不能包含对查询脚本进行简单剪切和粘贴的文本？而且，为什么错误文本实际上不能简单地告诉我它有什么问题？

- 更新我想到了。我正在执行的查询中有一个额外的疑难解答'select'语句。因此，proc实际上返回了两个记录集;一个非常普遍和可识别的情况（也是一个不是问题的情况）但执行文本中的情况是否已确定？

我明白了。我正在执行的查询中有一个额外的故障排除'select'语句。因此，proc实际上返回了两个记录集;一个非常普遍和可识别的情况（也是一个不是问题的情况）但执行文本中的情况是否已确定？
