Re: if else query help

hi Brian,

BCD> SELECT table2.date, count(table2.name) as count

BCD> AND table2.submitdate > 2 weeks

BCD> So i Guess my real questions is how do I determine the age of an entry to

Try this :

Select table2.date,count(table2.name) as count
from table1 as t1, table2 as t2
where t1.itemid=t2.itemid -- to link the tables
and t1.startdate>now()-14
and t2.submitdate>now()-14;

Someone corrects me if I'm wrong, I come from the Oracle world...

Dates (or I should say TimeStamps) are stored as floating point values
: the integer part is the number of days since a certain date
(epoch or 01/01/1970 on unix-based databases) and the fractionnal part is the
portion of the day (although I don't know --yet-- how to convert
date2-date1 to an integer, trunc does not work).
