Session variable problem : equality comparisons

Question

I have defined the following session variable returning the error *"[nQSError: 10058] A general error has occurred. [nQSError: 42040] The session variable, NQ_SESSION.TEST, is defined as Row-Wise Initialization. It is restricted to usage with equality comparisons. (HY000)"*
select 'TEST', organisatie_nummer
from st_organisatie
where (select case when regio = -1 then 1 else
regio_nummer end
from st_gebruikers
where upper(gebruiker) = upper('VALUEOF(NQ_SESSION.USER)')) =
(select case when regio = -1 then '1' else regio end
from st_gebruikers
where upper(gebruiker) = upper('VALUEOF(NQ_SESSION.USER)'))
Why this setup...a user can have access to 1 region or 'ALL' region. To make the 'ALL' available a dummy records has been inserted with a value of -1.
There's no problem to retrieve the region (another session variable), it returns '%' in case a user has all regions or the region name itself.
But i wanted to use this variable to retrieve the organisations linked to a region, but using a like statement or the query above isn't possible as it always returns the same error.
Someone any idea how to resolve this?!
Txs,
Andy

[nQSError: 10058] A general error has occurred. [nQSError: 42040] The session variable, NQ_SESSION.ORGANISATIE, is defined as Row-Wise Initialization. It is restricted to usage with equality comparisons. (HY000)
I transformed my query like this, I don't have any clue why this isn't working...if I run this sql statement it works perfect but not in OBi
select 'ORGANISATIE', organisatie_nummer
from st_organisatie
,(select gebruiker,regio from st_gebruikers) b
where case when b.regio = -1 then 1 else regio_nummer end
like
case when b.regio = -1 then '%' else b.regio end
and upper(gebruiker) = upper(':USER')
