首先抱歉我糟糕的英语。
现在问题上，我有一个包含2个表的数据集，每个表都有一个hundread字段有没有办法在数据表中插入所有数据而不必分配每个字段？。
我听说数据适配器可以实现这个，但由于源是另一个数据，我无法存档，或者我坚持用变量对每个字段进行设置？
目前我强力将源映射到插入。
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] + "','"

编辑：源是一个访问文件我试图将数据复制到as400数据库，现在我想念如何迭代所有数据表。

我不知道@ ValiRossi的解决方案;我从来没有这样做过。但我不会像那样创建你的INSERT语句。这可能导致SQL注入问题。
应该参数化。不幸的是，我的好例子正在起作用，但看起来像是：
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();
}
}
}

我不知道这是否有帮助，但最近我遇到了类似的问题。我从一种类型的数据库中获取数据，并希望将其插入另一种数据库中。我需要的是datarow.setadded（）方法，以使行实际插入。
foreach（dt.Rows中的DataRow博士） { dr.SetAdded（）; }
da.Update（DT）;
