DataException: The new column name or alias... [message #646002]

Hi all,

what does this error message means?

"The new column name or alias abc is already used by the column at index x"

I get this message several times when I run my report against another database, not the one used to create the report. The tables are identical but the column order is different.

I'm using Birt 2.5.2.

Please help

Regards
Helmut

Does the dataset have an alias on the columns?

Hi Jason!

No, the query ist really simple:

select *
from hsverf_dreh
where hsv_f_pan = ?
and hsv_geloescht = 0
order by hsv_sort

In the meantime I found a workaround. I listed all columns in the select clause instead of using *. Now the column order is always the same. But using * is more convenient. I would think of a bug in BIRT 2.5.2.

This sounds like a bug. Can you log it?

Found walk around.
Copy and Paste the same Date Source.
Then Double click the Data Set.
Go to Date Source Tab.
Change it to New Date Source.
Save.
Again Double click the Data Set.
Go to Date Source Tab.
Change it to Old Date Source.
Save.
Report worked for me.
