Hi, I have created DataTable “dt1” programmatically and enter query results in that datatable “dt1”.
Below is the code:
string strquery = "SELECT Name, Phones FROM Directory";
SqlCommand cmd = new SqlCommand(strquery, connection);
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd;
DataTable dt1 = new DataTable();
da.Fill(dt1);
---------------------------------------------------------------------
Now, I want to run Distinct query on one of the column “Phone” or Name and result should get store in another datatable.

How it can be done?

Regards,

Hi

// Get the distinct values applied on the column
string[] columns = {"Phone"};
DataTable distinctTable = dataTable.DefaultView.ToTable(true, columns);
