Hi to all.

In previous post we show  how to execute query in database. now in this post we see how to get data from database. and fill in DataTable.

for this we create on function in dbhelper class which we use in previous example.

        public DataTable FillDataTable(string sQry)
        {
            try
            {
                DataTable Dt = new DataTable();
             
               //Check db connection
                if (dbConnection.State != ConnectionState.Open)
                {
                    dbConnection.Open();
                }
                //create command
                OleDbCommand cmd = new OleDbCommand(sQry, dbConnection);
                //create OleDbDataAdapter for execute and get data
                OleDbDataAdapter ad = new OleDbDataAdapter(cmd);
                //fill datatable form data adapter
                ad.Fill(Dt);
                return Dt;
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }
