Hi, I suggestion for the date/time functions in the docs: http://www.postgresql.org/docs/8.0/interactive/functions-datetime.html
I was trying to figure out how to do: update table set next=now() + interval 'table.period seconds'; I tried subqueries, the concat operator, and anything else I could think of until I rediscovered the page on the various ways to cast. Perhaps mix up the examples in the docs so other ways to do date arithmetic (and that allow expressions, fields, etc.) are obvious: date '2001-09-28' + cast((7+7)||' seconds' as interval); date '2001-09-28' + ((7+7)||' seconds')::interval); etc. Or am I missing an easier way to do date arithmetic using a table's fields as part of the equation? (I think mysql has date_add(...), date_subtract(...), etc. CSN __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
