Oracle 在执行由 entity framework 6.0 生成的查询时抛出 ORA-00911 无效字符错误
Oracle throws ORA-00911 invalid character error while executing a query generated by entity framework 6.0
我在使用 Entity Framewrok 6.0 生成的以下查询时遇到问题。当我删除 where 子句时，查询执行得很好。但我看不到 where 子句的问题。你能帮我么？

我解决了问题。
我们在 c# 中用 StringLength 属性标记我们的 string 类型，以防止 Entity Framework 在 Oracle 上将它们创建为 NCLOB 列。然后 Entity Framework 为标有 StringLenth 属性的 c# 属性生成类型为 nvarchar 的列。
在这个查询中，where 子句由于 qoutes 而与 varchar2 一起工作（正如我从我的 Db 专业朋友那里了解到的那样。）所以我更改了列的类型并解决了。
