Oracle：算术运算导致溢出

Question

我的查询拉两个字符串 - 根本没有数字类型，但Oracle客户端给我上面的例外。有任何想法吗？

下面是该查询 - 所有字段都是字符串：

SELECT project_name 
     , project_title 
     , project_name as Job2 
     , project_name as Job1 
FROM PROJ 

这里是个例外：

System.OverflowException: Arithmetic operation resulted in an overflow. 
    at System.Data.Odbc.OdbcDataReader.FirstResult() 
    at System.Data.Odbc.OdbcCommand.ExecuteReaderObject(CommandBehavior behavior, String method, Boolean needReader, Object[] methodArguments, SQL_API odbcApiMethod)

拍摄，现在我还记得，我曾经见过这个。 Oracle客户端仅为32位。所以我的.NET应用程序需要x86编译。很烦人！这个消息是如此具有欺骗性。

Oracle ODBC驱动程序中的错误。它影响Oracle的版本：10.2.0.4到11.2.0.1，并且只影响64位驱动程序（不是32位驱动程序）。
