Access update statement not working in C#

Question

I'm going crazy trying to find out the reason why the below code won't update my database. I appreciate any help.
The connection string is correct and I'm able to execute similar commands, only this one is not working for some reason. Basically what I want is to replace occurrences of the value "1" with "123" in a column that I pass to the method.

        public void removeExpired2(string column, string user)
    {
        string connectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=d:\DB.accdb";

        using (OleDbConnection conn = new OleDbConnection(connectionString))
        {
            OleDbCommand cmd = new OleDbCommand("UPDATE [Reservations] SET [" + column + "] = @Column WHERE [" + column + "] = @ID");
            cmd.CommandType = CommandType.Text;
            cmd.Connection = conn;
            cmd.Parameters.AddWithValue("@Column", "123");
            cmd.Parameters.AddWithValue("@ID", "1");
            try
            {
                conn.Open();
                cmd.ExecuteNonQuery();
            }
            catch (Exception ex)
            {
                ScriptManager.RegisterClientScriptBlock(Button1, this.GetType(), "AlertMsg", "<script language='javascript'>alert('" + ex.Message.ToString() + "');</script>", false);
            }
        }
    }

Basically what I want is to replace occurrences of the value "1" with "123"

Your query is doing just opposite.

Change this

"UPDATE [Reservations] SET [" + column + "] = @Column WHERE [" + column + "] = @ID"

to

"UPDATE [Reservations] SET [" + column + "] = @ID WHERE [" + column + "] = @Column"

---

OR

Do this:

cmd.Parameters.AddWithValue("@Column", "123");
cmd.Parameters.AddWithValue("@ID", "1");

Answer 2

I had the command executed with two other commands, so I tried to separate them and it seems to have fixed the issue.
I moved one command into its own method and the remaining two are as they were before, and it's working now. Thanks everyone.
