Hi all,

I have a table acct as (username, terminatedate, terminatecause)
I would like to build a query which returns three columns orderd by data like:

date_trunc( 'day', terminatedate ) | count(cause1) | count(cause2)

where cause1/2 are two type of termination cause from the field
terminatecause.

for example acct table could be:

user1|01/01/2004 01:01:01| error
user2|01/01/2004 01:02:01| error
user1|01/01/2004 02:00:01| normal
user3|02/01/2004 10:00:01| normal
user2|02/01/2004 10:10:01| error

I would like to obtain:

date          |normal| error
01/01/2004|      1  |   2
02/01/2004|      1  |   1

Thanks in advance.

Roberto Fichera.
