ADO .NET OUT變量Oracle 10G與11G

Question

問題： 過程的OUT變量未返回。

背景： 我最近更新了一個從Oracle 10g到Oracle 11G的應用程序。我們正在使用Oracle客戶端的12c版本。

該應用程序在.NET 3.5上運行。

Database db = CreateDatabase(connectionName); 
      var dbCmd = db.GetStoredProcCommand(procedureName); 

      ConvertParams(ref dbCmd, parameters); 

      try 
      { 
       iReturn = db.ExecuteNonQuery(dbCmd, _transaction); 
       if (transaction == null) //if a transaction hasn't been passed, it isn't intended to has control over commit/rollback out of method, so app can do it 
        _transaction.Commit(); 
      } 
      catch (Exception ex) 
      { 
       if (transaction == null) 
        _transaction.Rollback(); 
       throw ex; 
      } 
      finally 
      { 
       DebugSpCommand(procedureName, parameters); 
       GetOutputParams(ref parameters, dbCmd); 
       if (transaction == null) 
       { 
        if (_transaction.Connection != null) 
         _transaction.Connection.Close(); 
        _transaction.Dispose(); 
       } 
      } 
     } 
     catch (OracleException ex) 
     { 
      Framework.ErrorHandling.ErrorHandler.HandleException(ex, "DATA_LAYER_POLICY"); 
      Framework.Logging.Logger.Write(ex.Message, LogCategories.Debug); 
      iReturn = ex.Code; 
     } 
     catch (Exception ex) 
     { 
      Framework.ErrorHandling.ErrorHandler.HandleException(ex, "DATA_LAYER_POLICY"); 
      Framework.Logging.Logger.Write(ex.Message, LogCategories.Debug); 
     }

您可以使用out變量在存儲過程
