Oracle：算術運算導致溢出

Question

我的查詢拉兩個字符串 - 根本沒有數字類型，但Oracle客戶端給我上面的例外。有任何想法嗎？

下面是該查詢 - 所有字段都是字符串：

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

這裏是個例外：

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) 
    at System.Data.Odbc.OdbcCommand.ExecuteReaderObject(CommandBehavior behavior, String method, Boolean needReader)

拍攝，現在我還記得，我曾經見過這個。 Oracle客戶端僅爲32位。所以我的.NET應用程序需要x86編譯。很煩人！這個消息是如此具有欺騙性。

Oracle ODBC驅動程序中的錯誤。它影響Oracle的版本：10.2.0.4到11.2.0.1，並且隻影響64位驅動程序（不是32位驅動程序）。
