Sql server 该列必须在编译时出现

由于您的

ALTER

语句（即DDL语句）将列

group\u id

添加到

#tmpImportData

，该列不能在同一批中的

UPDATE

语句中使用。

因为不能执行添加列的DDL查询，然后执行在同一批中使用该列的DML查询

这里有一篇文章更详细地回答了这个问题，尽管它来自一个与你的问题相反的问题：

具体而言：

SQL在执行批处理之前编译批处理。（批处理是GO命令之间的所有内容）。编译时，如果命令引用表中存在的列，则该列必须在编译时出现

DDE是否代表动态数据交换？还有，你应该知道。alter语句不会将列添加到tmp表中。我必须返回并突出显示它，然后运行它以添加它们。@CodeFlava--DDE应该是DDL。我已经修好了。另外，您的alter语句确实添加了列：

altertable#tmpImportData add group_id INT

我之所以这么说是因为它运行之后。选择不会导致显示任何结果。因此，如果我突出显示select*和f5，它将显示没有添加列的表。所以我突出显示alter语句，然后点击f5。然后运行select。他们现在在那里。。。我希望StackOverflow能让我们添加视频…DDE代表动态数据交换吗？还有，你应该知道。alter语句不会将列添加到tmp表中。我必须返回并突出显示它，然后运行它以添加它们。@CodeFlava--DDE应该是DDL。我已经修好了。另外，您的alter语句确实添加了列：
