Question

我在SQL Server 2000的石器时代编写了一个相当古老而且很长的查询。您可能怀疑这会使用像c.address_id =* b.address_id这样的旧连接

当我尝试运行它时，会弹出一条错误消息，我必须将兼容级别设置为80以启用此类型的连接。我试过这种方式：

ALTER DATABASE SandBox
SET compatibility_level = 80

但似乎这被忽略了。该脚本大约有800行 - 所以有没有办法在MSSQL 2008中运行此查询而不重写它？

需要每周运行两次，所以这次我不会关心脚本的性能等。

欢迎任何建议。

我会改写它。

话虽如此，这对我有用。

ALTER DATABASE ScratchPadDB
SET compatibility_level = 80

到目前为止您还没有完全确定您尝试了什么，但在当前脚本中执行它不一定有效。如果仍然难以设置兼容级别，请尝试打开新的查询窗口并仅运行该部分。
