Hello;
I've got the result of a query that appears as:
cod_variable | cod_station | year | month | day | rain
---------------------+-------------------+--------+----------+------+------
30201 | 7237 | 1953 | 1 | 1 | 2
30201 | 7237 | 1953 | 2 | 1 | 5
30201 | 7237 | 1953 | 3 | 1 | 0
30201 | 7237 | 1953 | 4 | 1 | -3
.....
(Of course, thanks to Stephan Szabo for the method to obtain this from my
strange source data. I didn't think this was possible.)
After have done this query I've realized that I need the data to be ordered
by date. Do you have any suggestion?
Best regards
----------
Javier

select <your cols>,year,month,day from <your table> order by
year,month,day.
Also take a look at date,timestamp data types.
Note that you can process your initial "strange" source
using tools as awk,perl,sh,C programs to format
your datasets in sql insert statements or
copy format.
