As a computer language, the SQL is used to give instructions to an internal program called an interpreter. You must make sure you give precise instructions. SQL is not case-sensitive.

If you are creating a web site, you can write the necessary code. Once your code is ready, you can pass it to a OleDbCommand object you would have created. This would be done as follows:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.OleDb;

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
        using (OleDbConnection connection =
            new OleDbConnection("Provider=Microsoft.Jet.OLE.4.0;" +
                    "Data Source=" + Server.MapPath("App_Data/exercise.mdb")))
        {
            OleDbCommand CommandToExecute = new OleDbCommand(SQL Code, connection);
        }
    }
}

In this example, the SQL Code factor represents a SQL statement you would write and pass it as a string.

After passing the SQL code to a command, to execute it, you can call the ExecuteNonQuery() method of your OleDbCommand object. This would be done as follows:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.OleDb;

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
        using (OleDbConnection connection =
            new OleDbConnection("Provider=Microsoft.Jet.OLE.4.0;" +
                    "Data Source=" + Server.MapPath("App_Data/exercise.mdb")))
        {
            OleDbCommand command = new OleDbCommand(SQL Code, connection);

            connection.Open();
            command.ExecuteNonQuery();
        }
    }
}
