Try it both with and without the LIMIT 1 and see if your results are any different.
If they are--with that query written as is--I owe you a latte.
You only use LIMIT when your query is going to return more records than you want.
And in any case, a LIMIT used *WITHOUT* and ORDER BY clause is worse than useless.
