Question

I can’t understand what I am doing wrong, I can’t seem to SELECT with a prepared statement. However I can INSERT with a prepared statement.

MySqlCommand cmd = new MySqlCommand("SELECT * FROM code_post WHERE name = ?postRequired LIMIT 1",  dbcon);
cmd.Parameters.Add(new MySqlParameter("?postRequired", requestString));
cmd.ExecuteNonQuery();

DataSet ds = new DataSet();
cmd.fill(ds, "result");
try {
             thisBlog = ds.Tables["result"].Rows[0];
} catch {
             invalid();
             return;
}

Any advice on this would be greatly appreciated!

To fill a DataSet you will need a DataAdapter.

Try this:

MySqlCommand cmd = new MySqlCommand("SELECT * FROM code_post WHERE name = ?postRequired LIMIT 1",  dbcon);
cmd.Parameters.Add(new MySqlParameter("?postRequired", requestString));
cmd.ExecuteNonQuery();

DataSet ds = new DataSet();
MySqlDataAdapter dAdap = new MySqlDataAdapter();
dAdap.SelectCommand = cmd;
dAdap.Fill(ds, "result");
try {
             thisBlog = ds.Tables["result"].Rows[0];
} catch {
             invalid();
             return;
}
