The problem does not occur anymore after i did a backup of the db on ib
5.6 and restored it on firebird, which i didn't do before.
Still dialect 1 now but it seems to work ok again.

Hi all

We have moved to Firebird 1.5 yesterday from interbase 5.6 and i
encouter similar problems as Jason S.has
I have a TIB_Query containing a sql like this:
select
pn_id,
pn_nam,
(select f_dectotime(sum(rud_totaaldec))
from rudpx
where (rud_per = j2w_pnpx.pn_id)
and (rud_soort = 'U')
and (rud_verlof = 1)
and f_striptime(rud_dat)>= :datum) as verlof
from j2w_pnpx
where (pn_id = :persoon)

If i don't do the select with the sum the parameter :persoon is
recognised as a varchar(4) which is correct.
If i include it the parameter :persoon is recognised as a Timestamp,
which i can't understand.

This is a major problem.
If i execute the sql in ibexpert on the firebird db it works fine, i
don't know why TIB_Query thinks :persoon is a Timestamp and i see no way
to force it to accept it as a varchar(4)
On Interbase 5.6 the parameters were recognised correctly.

D7ent with ibobjects 4.3.A on firebird 1.5

Any help will be most appreciated

Franky

If you assign the param values in code, do it like this:

MyQuery->ParamByName( "DATE1" )->AsDateTime = ...
