Session variable problem : equality comparisons

ADBDec 10 2008 — edited Dec 11 2008
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

Hi Andy,

first of all, I don't really understand your SQL query. Nevertheless, I am wondering why you have used Row-Wise Initialization for this session variable, if you only want value "ALL" or the name of the region for the TEST session variable.

in case a user has 'all' regions dedicated, I want to see all the organisations otherwise I only want to see the organisations linked to the specific region.

As I can't use a 'LIKE' (see error that you can only use =) into the session variable, I've worked something out returning the column name (user has 1 region) or 1 (user has all regions).

I hope it's more clear now.

So a user is joined to one or all regions and an organizations is joined to a region. Why don't you create one query, in which you join all the required tables?

[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')
ADB
Even after trying to create a view of the query and using this view within my session variable i have the same error.

My query is
select 'PARAM', organisatienummer
from vw_org
where upper(gebruiker) = upper(':USER')

It makes me desperate, so all help is welcome!

Kr,

I think your query should look like this:

SELECT 'ORGANISATIE', o.organisatie_nummer
FROM st_organisatie o, st_gebruikers g
WHERE o.regio_nummer = g.regio_nummer AND g.gebruiker = 'UPPER(VALUEOF(NQ_SESSION.USER))'

:-) I know it should look like that, but that's the problem.

I don't have organisation for id = -1, that's why a make a translation of it towards a %

And even whenI put my values into a table I receive this error.....I'm lost...

Hi...

For your view approach post..
As per my knowledge... USER is the keyword for ORACLE, so it will n't accept it as bind variable.. as you are using...
So try give other name..

Thanks & Regards

Hi kishore,

txs but as I have the same prob when using a table, I guess there's something else;

Also when using valueof(nqsession.user) i have probs :-(

hi....

I am not sure this.. but try using content filter of particular logical table source...

Thanks & Regards

In my opinion this is not an OBIEE problem but a SQL / data problem.
I would advise you to fill your regio table with all correct combinations of regio and gebruiker and create the query as mentioned before.

Stijn
