Microsoft SQL链接MySQL服务器 - 无法从PHP进行查询

Question

我在Microsoft SQL Server上设置了链接MySQL服务器。我可以在MSSQL Management Studio中成功运行此查询...

SELECT * FROM OPENQUERY(MYSQL, 'SELECT * FROM countries') 

当我跑这从一个PHP的网站，虽然，我得到这个错误...

Message: Failed to query SQL statement. Reason: Heterogeneous queries require the ANSI_NULLS and ANSI_WARNINGS options to be set for the connection. This ensures consistent query semantics. Enable these options and then reissue your query. 

任何想法我可以做得到这个工作？

Answer 1

解决方法是将链接服务器调用下方的“SET ANSI_WARNINGS OFF”语句转移。为了保证安全，请在sp/query结尾处应用“SET ANSI_WARNINGS ON”语句。

更新

SET ANSI_WARNINGS ON 

SET ANSI_NULLS ON 

SELECT * FROM OPENQUERY(MYSQL, 'SELECT * FROM countries')
