ok, i solved-up the problem ! tnx to Nabil who helped me.
I've had already tried nesting two SELECTs, but without results... now your
answer made me think deeper at this solution, and i came to this solution (i
think it's quite self-explanatory even if you donnow Zope):
<dtml-in "dbpower_save.sql_search_real_time()" size=3 orphan=0>
<dtml-in "dbpower_save.sql_search_real_time_ts({
'now': ZopeTime().strftime('%Y-%m-%d'),
'real_time_ts.id_real_time': id_real_time })"
size=1 orphan=0>
bye
have a nice day
