Hi,

I have two sql servers(one of them is in my web server: server A, another one is local: server B)

I use the code bellow to copy data on a table in SQL SERVER A to another table in SQL SERVER B :
(different servers & different databases.. **the two tables are same in columns**)

ON for server A

OFF for server B

C#

string strsql = "SELECT * FROM **serverA_table**";
ONda = new SqlDataAdapter(strsql, ONcon);
ONds = new DataSet();
ONda.Fill(ONds, "serverA_table");


strsql = "SELECT * FROM serverB_table";
OFFda = new SqlDataAdapter(strsql, OFFcon);
OFFds = new DataSet();
OFFda.Fill(OFFds, "serverB_table");

DataRow[] newRow = ONds.Tables["serverA_table"].Select();

DataTable dtTarget = new DataTable();
dtTarget = OFFds.Tables["serverB_table"].Clone();

foreach (DataRow temp in newRow)
{
    dtTarget.ImportRow(temp);
}



SqlCommandBuilder cb = new SqlCommandBuilder(OFFda);
OFFda.InsertCommand = cb.GetInsertCommand();
OFFda.UpdateCommand = cb.GetUpdateCommand();
OFFda.DeleteCommand = cb.GetDeleteCommand();
OFFda.Update(OFFds.Tables["serverB_table"]);

But NOTHING happens and no row is added(imported) to my serverB_table !

please help me with this code or let me know a new way to do this action !

thanks in advance.

I used this code too, and no difference:

foreach (DataRow temp in ONds.Tables["serverA_table"].Rows)
{
OFFds.Tables["serverB_tanle"].ImportRow(temp);
}
OFFds.Tables["serverB_table"].AcceptChanges();

If table schema is same you can use Marge method in your code. than add table to your data-set.

C#

 DataTable ONdt = new DataTable();
 DataTable OFFdt = new DataTable();
string strsql = "SELECT * FROM **serverA_table**";
           ONda = new SqlDataAdapter(strsql, ONcon);
           ONds = new DataSet();
           ONda.Fill(ONdt);


           strsql = "SELECT * FROM serverB_table";
           OFFda = new SqlDataAdapter(strsql, OFFcon);
           OFFds = new DataSet();
           OFFda.Fill(OFFdt);
OFFdt.Merge(ONdt);
// Than add it to your Dataset 
OFFds.Tables.Add(OFFdt);

C#
