dataadapter填表（as400）

首先对不起我的糟糕英语。dataadapter填表（as400）

现在在这个问题上，我有一个数据集包含2个表，每个表都有一个hundread字段有没有办法将所有数据插入到数据表中而不必分配每个字段？

我听说dataadapter可以实现这一点，但由于源是另一个数据，我一直无法将其归档，或者我坚持要为每个字段赋一个变量？

此刻我强烈地将源映射到插入。

 try 
     { 
      connection.Open(); 
      DateTime fecha1 = Convert.ToDateTime(ds.Tables[0].Rows[0][4].ToString()); 
      DateTime fecha2 = Convert.ToDateTime(ds.Tables[0].Rows[0][12].ToString()); 
      DateTime fecha3 = Convert.ToDateTime(ds.Tables[0].Rows[0][61].ToString()); 
      query = "INSERT INTO HDZSNC.RELTRM VALUES ('" + ds.Tables[0].Rows[0][0] + "','" 
      + ds.Tables[0].Rows[0][1] + "'," + ds.Tables[0].Rows[0][2] + ",'" + ds.Tables[0].Rows[0][3] + "'," 
      + String.Format("{0:yyyyddMM}", fecha1) + "," + ds.Tables[0].Rows[0][5] + ",'" + ds.Tables[0].Rows[0][6] + "',"

     catch (Exception ex)

      MessageBox.Show("No se puede abrir la coneccion a 400 " + ex, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); 
      return; 
     }

编辑：来源是我试图将数据复制到AS400数据库，现在我很想念如何与所有的数据表遍历一个访问文件。

你的英语是没有问题的，但目前还不清楚你想要达到的目标。它是一个强类型数据集，源是什么，源和目标是相同的方案？ –

@Tim Schemelter：多年来我一直没有和编程联系，是的数据集是强类型的，源有不同的方案（老实说，他们告诉我它是相同的，但事实并非如此）。 – Enrique

我不知道@ValiRossi的解决方案;我从来没有这样做过。但我不会创建你的INSERT这样的陈述。这可能会导致SQL注入问题。

它应该被参数化。不幸的是，我的好例子是在工作，但它看起来是这样的：

public void CreateNewLeaveRequestDate(DayRequested dayRequested) 
    { 
     /* 
      INSERT INTO MPRLRREQDP 
      (REQUEST_ID, DATE_OF_LEAVE, TIME_OF_LEAVE, HOURS_REQUESTED, REQUEST_TYPE, RELATIONSHIP, NATURE_OF_ILLNESS, 
       ADDED_TO_TIMESHEET, EMPLOYEE_ID, TIMESHEET_CODE) 
      VALUES(NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL)         
     */ 

     StringBuilder sb = new StringBuilder(); 
     sb.Append("INSERT INTO MPRLRREQDP "); 
     sb.Append("(REQUEST_ID, DATE_OF_LEAVE, TIME_OF_LEAVE, HOURS_REQUESTED, REQUEST_TYPE, RELATIONSHIP, NATURE_OF_ILLNESS, "); 
     sb.Append("ADDED_TO_TIMESHEET, EMPLOYEE_ID, TIMESHEET_CODE) "); 
     sb.Append("VALUES(@REQUEST_ID, @DATE_OF_LEAVE, @TIME_OF_LEAVE, @HOURS_REQUESTED, @REQUEST_TYPE, @RELATIONSHIP, @NATURE_OF_ILLNESS, "); 
     sb.Append("@ADDED_TO_TIMESHEET, @EMPLOYEE_ID, @TIMESHEET_CODE)"); 

     using (iDB2Connection conn = new iDB2Connection(ConfigurationManager.ConnectionStrings["IbmIConnectionString"].ConnectionString)) 
     { 
      using (iDB2Command cmd = new iDB2Command(sb.ToString(), conn)) 
      { 
       cmd.Parameters.Add("@REQUEST_ID", iDB2DbType.iDB2Decimal).Value = dayRequested.RequestId; 
       cmd.Parameters.Add("@DATE_OF_LEAVE", iDB2DbType.iDB2Date).Value = Convert.ToDateTime(dayRequested.DateOfLeave).Date; 
       cmd.Parameters.Add("@TIME_OF_LEAVE", iDB2DbType.iDB2Time).Value = Convert.ToDateTime(dayRequested.TimeOfLeave).ToString("HH.mm.ss"); 
       cmd.Parameters.Add("@HOURS_REQUESTED", iDB2DbType.iDB2Decimal).Value = dayRequested.HoursRequested; 
       cmd.Parameters.Add("@REQUEST_TYPE", iDB2DbType.iDB2Decimal).Value = dayRequested.RequestType; 
       cmd.Parameters.Add("@RELATIONSHIP", iDB2DbType.iDB2Char).Value = dayRequested.Relationship; 
       cmd.Parameters.Add("@NATURE_OF_ILLNESS", iDB2DbType.iDB2Char).Value = dayRequested.NatureOfIllness; 
       cmd.Parameters.Add("@ADDED_TO_TIMESHEET", iDB2DbType.iDB2Decimal).Value = false; 
       cmd.Parameters.Add("@EMPLOYEE_ID", iDB2DbType.iDB2Decimal).Value = dayRequested.EmployeeId; 
       cmd.Parameters.Add("@TIMESHEET_CODE", iDB2DbType.iDB2Char).Value = dayRequested.TimesheetCode; 
       conn.Open(); 
       cmd.ExecuteNonQuery(); 
       conn.Close(); 
      } 
     } 
    }

@Enrique我已经将示例更新为来自我的应用程序的副本和粘贴示例。 –

我不知道这是否有帮助，但我最近有类似的问题。我从一种类型的数据库中获取数据，并希望将其插入另一个数据库中。我需要的是datarow.setadded（）方法来实际插入行。

foreach（DataRow dr in dt.Rows） dr.SetAdded（）; }

da.Update（dt）;

我从来没有尝试过......我必须尝试一段时间。 –

@ValiRossi Nvm我把你带到这里，有趣的方式，但遗憾的是，如果没有这种完美的方式，这个方案会有点不同。 – Enrique
