I am using an Oracle instant client 10.2 to access an Oracle 8i database.

My first problem is that the designer shows only 100 data tables in the schema that I specified. There should be more than 500 tables though. Is there a setting that limits the schema table count to 100?

A bigger problem is that I can only use one string parameter in the query. When I introduce a second parameter and try "Preview Results" (or anything else that tries to run the query), I get an error. Can I actually use more than one parameter in a query? This is the error I am getting:

The schemas/tables are limited in the preferences:

Window -> Preferences -> Report Design -> Data Set Editor -> JDBC Data Set

For the second issue, can you attach your design?

Thanks a lot! I suspected something like this, 100 was too straight to be accidental. Smile

As for the second issue, I have attached the design file now. I am trying to introduce a second parameter into the query, replacing the line

"and t1.MNR <= '0Z'"

by

"and t1.MNR <= ?"

Also, I add another parameter, named "BisArtikel", string type, direction input. In the value field I enter "0Z" (sans the quotes). As soon as I click on "Output columns" or "Preview Results" I get an error about a ";" (semicolon) missing.

Thanks for taking the time to look into this.

Can you try rebuilding the dataSet from scratch? If that doesn't work, you could always add/modify the where statement in your dataSet's beforeOpen script.

Hm, I tried rebuilding the data set from scratch, at first with the same problems. But when I introduced report parameters, it suddenly worked. So the problem seems to be parameters in the dataset that are not linked to report parameters.

As you can probably guess, I am fairly new to BIRT, so I have no idea if dataset parameters without report parameters make any sense at all. Although maybe they could be set in a script or so.

I tried rebuilding the dataset from scratch and got the same results. But when I introduced report parameters assigned to the dataset parameters, everything worked fine.

I am new to BIRT so I have no idea if a dataset parameter makes sense without an assigned report parameter. I can imagine that one might want to set a dataset parameter value in a script. Still, if it works with one parameter, I would assume that it should work with more than one parameter too.

Thanks for your time!

Guessing this thread is answered. Still, BIRT does work with multiple parameters even if you have to use the same param again and again.. is this problem similar ? you got to use a beforeOpen script on dataset to implement this.
