This is from Help:
A HAVING clause without a GROUP BY clause acts like a WHERE clause. You can use local aliases and field functions in the HAVING clause. Use a WHERE clause for faster performance if your HAVING clause contains no field functions. Note that the HAVING clause should appear before an INTO clause or a syntax error occurs.
