Good Mornig Malik1122 We cant know what is the Problem until we see the code, another thing that can be easly done on the SQL. e.g

INSERT INTO TABLE2
SELECT COL1,COL2 FROM TABLE1
WHERE COL1 IS NOT NULL

Always try to keep the sql side in SQl , because these things can be achieve at ease that side than trying to loop through a datatable. Please explain clearly what is your problem.

int colm = 0; if (objBUS.busDataSet.Tables["tblSwapedColumns"].Columns.Count > 0) { for (int X = 0; X < objBUS.busDataSet.Tables["tblSwapedColumns"].Columns.Count; X++) { if (objBUS.busDataSet.Tables["tblSwapedColumns"].Columns[X].ToString() == objBUS.busDataSet.Tables["tbl"].Columns[colm].ToString()) { if (colm == 0) { for (int Q = 0; Q < objBUS.busDataSet.Tables["tbl"].Rows.Count; Q++) { objBUS.busDataSet.Tables["tblSwapedColumns"].Rows.Clear(); DataRow DRow = objBUS.tblSwapedColumns.NewRow(); DRow[objBUS.busDataSet.Tables["tblSwapedColumns"].Columns[X]] = objBUS.busDataSet.Tables["tbl"].Rows[Q][colm].ToString();//here code //give exception "Column 'FIRST NAME' does not belong to table tblSwapedColumns" //'FIRST NAME' is the column name which is previously present in the table. objBUS.tblSwapedColumns.Rows.Add(DRow); } colm++; } else { for (int Q = 0; Q < objBUS.busDataSet.Tables["tbl"].Rows.Count; Q++) { objBUS.busDataSet.Tables["tblSwapedColumns"].Rows[X][Q] = objBUS.busDataSet.Tables["tbl"].Rows[X][colm].ToString(); objBUS.busDataSet.Tables["tblSwapedColumns"].AcceptChanges(); } colm++; } } } }

The column of 'tbl' are 1. FIRST NAME 2. LAST NAME 3. DATE OF BIRTH 4. AGE 5. GENDER And that of 'tblSwapedColumns' are 1. GENDER 2. DATE OF BIRTH 3. AGE 4. LAST NAME 5. FIRST NAME

The Problem might be the names of your Columns in SQl it would be fine. Try not to name your Field names with Spaces , when Defining your Column names use something like th First_Name or Firstname Last_Name or LastName please Fix that and try to run your code again

I'm not using any SQL Query to fill datatable. I'm just coying data from one datatable to an other datatable without the use of any Query.

Hi Malik. Just Assign one table to other like DataTable dt=datatable; if one table already contains some records and you don't want to loss that then use the following code.

//copy tbl1 to tbl2
public DataTable MergTables(DataTable tbl1, DataTable tbl2)
{
if (tbl1.Rows.Count > 0)
{
foreach (DataRow row in tbl1.Rows)
{
DataRow newrow = tbl2.NewRow();
newrow["Col1"] = row["Col1"].ToString();
newrow["Col2"] = row["Col2"].ToString();
newrow["Col3"] = row["Col3"].ToString();
tbl2.Rows.Add(newrow);
tbl2.AcceptChanges();

            }
        }
        return tbl2;
    }
