Direct database request and session variable value

Question

Hi,
I have a problem by doing the following : idea is to have report with a list of all tables in user schema (which are not all in repository physical layer).
By clicking on the name of any, should bring answer report which is done as direct database request doing basically select * from table_clicked (this will be basically the same table with sufix _err holding error rows).
What I'm trying to do is having some kind report for error rows which can be in different tables in my database. So i had in mind to construct name of table i need , and pass it to database request through session variable. Am i doing right by doing direct database request like this :
select * from 'VALUEOF(NQ_SESSION.TestVar2)'
Is there another easyer way of doing this? I know this can be done by gourl by passing parameters but not sure how when i can't filter columns in direct database request (this can be different tables with different names of columns). I hope i didn't complicated this too much.
Thnx in adwance

Answer 1

Hi,
I know this is a hack, and would be much more easy to create one table with dimension and measures, but this is intended to be used with code generator, which can produce different error tables with different column names in different time: It is not conviniet for somebody to add them to repository every 5 minutes. For example : i run my workflow and for first run I have errors in table1(let us say customer table with 30 columns) and if click on the table name in some answer report, i want to see all the bad records in the table. Tomorrow after the run, there are bad records in table1 and in table2 (lets say products) so I would have choice to pick table 1 or table2 and see al the bad records in any of these tables. This means that I can not now which tables will I have tomorrow, and as it is generic, I can manually add some tables in my model, and would have to add err table also as a possibility to have error rows?
I saw post saying that you can pass parameter value by using go url functionality, by modifying configinstance file, but didn't suceed - http://gerardnico.com/wiki/dat/obiee/logical_sql/obiee_session_variable_go_url . Maybe some mistake or any better solution? I created session variable TestVar2, also modified instanceconfig.xml by adding this before </ServerInstance>
<ParamList>
<Param name="NQ_SESSION.TestVar2" source="url" nameInSource="SETVAR"/>
</ParamList>
and used go url in column formula : ''||"Physical Targets"."Physical Table"||''
Can I use @1 for using first column value?
Thnx
