Question

我在Stackoverflow和其他地方看过很多示例和问题/答案。我不明白为什么我的C＃没有看到Oracle SP。任何帮助将不胜感激。

基本目标 -

我有一个Oracle SP（如下所示），它在返回参数＃1中返回一个游标，并在＃2和＃3中给出两个字符串参数。

我从C＃调用SP，尝试将返回的Resultset放入Class ExtractCoastalSurvey1SP的C＃List中。（如下所示）

我的代码在Nhibernate命令GetNamedQuery上爆炸。

Oracle SP，NHibernate映射XML文件，NHibernate映射代码，调用代码和运行时错误转储如下。

如果您需要更多信息，请告诉我 - gmail.com中的sblalock。

感谢您的帮助。解决这个问题，并在我眼中升到神的地位！干杯，祝福有个美好的一天！

Answer 1

将模式名称附加到过程时会发生什么？如[schema]。[procedure]。

对于我在C＃应用程序中的打包代码，我总是把光标放在最后但是对于fluent-nhibernate来说这可能不是必需的

运行时错误 - 命名查询未知 - Nibernate，Oracle，C＃
