Answer / ankur sehgal
Consider a dataset(ds) having two datatables or we can say
that it contains data from two tables..
System.Data.DataTable dt = new DataTable();
dt.Columns.Add("Field1", typeof(string));
dt.Columns.Add("Field2", typeof(string));
if(ds.Tables[0].Rows.Count > 0)
{
foreach(DataRow dr in ds.Tables[0].Rows)
{
DrNew = dt.NewRow();
DrNew[0] = dr["Field1"].ToString();
}
}
if(ds.Tables[1].Rows.Count > 0)
{
foreach(DataRow dr in ds.Tables[1].Rows)
{
DrNew = dt.NewRow();
DrNew[0] = dr["Field2"].ToString();
}
}
dt.AcceptChanges();

DataTable dt1 = retDT("select col1,col2 from Table1");
DataTable dt2 = retDT("select col3,col4 from Table2");

You Can Write Query :
select (databasename).(owner).(tablename1).
(datafield),select (databasename).(owner).(tablename2).
(datafield) from (databasename).(owner).(tablename1),
(databasename).(owner).(tablename2)
Example:select
LSKGROUP.dbo.addsites.state,LSKGROUP.dbo.employee.empname
from LSKGROUP.dbo.addsites,LSKGROUP.dbo.employee
and then fill the values to new dataset table.
Remember:
if database also differ put databse's name accordingly
Good Luck.....
