Hi:
Thanks for your reply but...

mysql> select obs_id, obs_URI, obs_source, beg_date, beg_time from
observation where beg_date between 19990120 and 19990530;
Empty set (0.21 sec)

and you can see that there is data within this range:

mysql> select obs_id, obs_URI, obs_source, beg_date, beg_time from
observation where beg_date between '1999-01-20' and '1999-05-30';
+--------+------------------------------------+------------+------------+----------+
| obs_id | obs_URI                            | obs_source | beg_date   |
beg_time |

6 rows in set (0.01 sec)

The quotes are not the problem because the string is translated to a date
format when using the equal (=) sign. I think is something with the
implementation of the between clause, dates and numbers.
