SQL MIN returns null ( = a row without data) as a default value if there is no data to calculate the MIN value of. Pretty much all aggregate functions return a default value (count() returns 0 for example).
You would only get no result at all if your query uses a GROUP BY clause and no group exists, e.g. SELECT MIN(value) FROM table GROUP BY data HAVING data = 'non existent data'. *Also, if you are not familiar with it, you should definitely read up SQL injection.* -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
