If it just about displaying the data twice then no need to insert duplicate data in your table simply follow the guidelines below

C#

OleDbConnection  con = new OleDbConnection ();
con.ConnectionString = "your connection string here";
con.Open();
OleDbCommand cmd=new OleDbCommand();
cmd.CommandText = "Select * from dbo_NR_HMSWD50SQ_01_147";
OleDbDataAdapter adp = new OleDbDataAdapter(cmd.CommandText , con);
            
//Create two datatables

DataTable ds = new DataTable();
DataTable  ds1 = new DataTable();
           
//Fill them with same data

 adp.Fill(ds);
adp.Fill(ds1);

//merge them to one datatable

ds.Merge(ds1);

//and display in your gridview

dataGridView1.DataSource = ds;

I hope this helps you........
