Sybase数据源参数的用途是什么?

标签: coldfusion sybase quoted-identifier

我对数据源中设置的参数有疑问。我支持的项目非常老,并且将Sybase与ColdFusion 11一起使用。我在本地计算机上更新了一些代码,一切正常。将相同的代码滚动到开发服务器后,我收到一条错误消息。很快,我意识到这与cfqueryparams有关。我一删除它们,代码就可以正常工作。然后,我在开发服务器上的数据源中找到了它:

jdbc:sybase:Tds:example.com:5000/devtest?SQLINITSTRING=set QUOTED_IDENTIFIER off

我想知道此参数的目的是什么?这是否使我们的系统受益于附加的安全层?团队中没有人对此一无所知,他们也不想触及该代码。我想更多地了解这一点,并了解其用途。

根据@Ageax的建议,我尝试转储cfsavecontent,这是输出:

我尝试运行上面的代码,就像在cffunction中一样,这是错误消息:

The system has attempted to use an undefined value, which usually indicates a programming error, either in your code or some system code.

Null Pointers are another name for undefined values.

我不确定原因是什么,什么原因会导致问题,因为一切似乎都非常简单。
