Hello Sijo First off you need to download and install ODP from this site http://www.oracle.com/technetwork/topics/dotnet/index-085163.html After installation add a reference of the assembly Oracle.DataAccess.dll. using Oracle.DataAccess.Client; // ODP.NET Oracle managed provider using Oracle.DataAccess.Types; Class Test { string oradb = Data Source=ORCL;User Id=hr;Password=hr;; OracleConnection conn = new OracleConnection(oradb); // C# conn.Open(); OracleCommand cmd = new OracleCommand(); cmd.Connection = conn; cmd.CommandText = select department_name from departments where department_id = 10; cmd.CommandType = CommandType.Text; OracleDataReader dr = cmd.ExecuteReader(); dr.Read(); label1.Text = dr.GetString(0); conn.Dispose(); } For more details please refer : http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/dotnet/GettingStartedNETVersion/GettingStartedNETVersion.htm T hanks
