There is no such thing as ASAP ;) Assuming you know how to setup a connection to the database, the following show the basics to retrieve all records with ID 101 // ID of interest int theID = 101; // the query; not the use of the parameter SqlCommand cmd = new SqlCommand("select * from mytable where ID = @pID", myConnection); // set the command type cmd.CommandType = System.Data.CommandType.Text; // add the parameter cmd.Parameters.AddWithValue("@pID", theID); // define a table to store results DataTable tbl = new DataTable(); // execute query and populate table tbl.Load(cmd.ExecuteReader()); You need to 'include' the namespaces System.Data and System.Data.SqlClient .
