 datediff is there something like it? Hi all working my way through our views and all is going very well. We use datediff in MSSQL a bit and I read about the field1::date - field2::date to return the days numerically. Is there any way to get months and years besides guessing days / 30 for months etc?

Go to http://www.postgresql.org/docs/7.4/i...-datetime.html Check out smth like... SELECT 'Achilleus is ' || date_part('years',age(timestamp '1969-01-31')) || ' years and ' || date_part('months',age(timestamp '1969-01-31')) || ' months old'; ?column? ----------------------------------------- Achilleus is 35 years and 11 months old (1 row) > > > > Joel Fradkin > > > > Wazagua, Inc. > 2520 Trailmate Dr > Sarasota, Florida 34243 > Tel. 941-753-7111 ext 305 > > > > jfradkin@wazagua.com > www.wazagua.com > Powered by Wazagua > Providing you with the latest Web-based technology & advanced tools. > C 2004.

| Re: datediff is there something like it? Yes I am using datepart, but not seeing how with a datediff. Maybe I just need to do the date math and put a date part on the result. I will play around a bit when I hit one not looking for days.

The age function will give a difference in years-months in addition to days-hours-minutes-seconds. Depending on what you want, it may not do exactly what you want. ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to majordomo@postgresql.org) |
