Обсуждение: ORDER the result of a query by date
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 | 230201 | 7237 | 1953 | 2 | 1 | 530201 | 7237 | 1953 | 3 | 1 | 030201 | 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

Do you have any suggestion? 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. > > Best regards > ---------- > Javier > > ---------------------------(end of broadcast)--------------------------- > TIP 5: Have you checked our extensive FAQ? > > http://www.postgresql.org/users-lounge/docs/faq.html > ================================================================== Achilleus Mantzios S/W Engineer IT dept Dynacom Tankers Mngmt Nikis 4, Glyfada Athens 16610 Greece tel: +30-10-8981112 fax: +30-10-8981877 email: achill@matrix.gatewaynet.com mantzios@softlab.ece.ntua.gr
