SQL Server兼容性問題

Question

我有一個相當老而且很長的查詢，寫在SQL Server 2000的石器時代。您可能會懷疑它使用了像c.address_id =* b.address_id這樣的舊聯接。

當我嘗試運行它時，彈出錯誤消息，我必須將兼容性級別設置為80才能啟用這種類型的聯接。 我已經嘗試過這種方式：

ALTER DATABASE SandBox
SET compatibility_level = 80

但這似乎被忽略了。 該腳本大約有800行-那么有什么方法可以在MSSQL 2008中運行該查詢而無需重寫它？

它需要每周運行兩次，過夜，所以這次我不會在意腳本的性能，等等。

歡迎任何建議。

Answer 1

我會重寫它。

話雖如此，這對我有用。

ALTER DATABASE ScratchPadDB
SET compatibility_level = 80

Select * from

Where
d.DepartmentUUID =* e.ParentDepartmentUUID

不確定目前為止您嘗試了什么，但是不一定要在當前腳本中執行它。 如果仍然難以設置兼容性級別，請嘗試打開一個新的查詢窗口並僅運行該部分。
