Googlebot envokes error message.

Posted:31 Oct 2009 (20:24 UTC)
Through the Admin email I get the following message:

ERROR CODE: Errno: 1054 Message: Unknown column 'poveepqqcilnin' in 'order clause'

Running 2.7 rc1. Can somebody explain this please?

poveepqqcilnin is probably being supplied as a part of the page request. Order by provided as an selectable option, so without knowing what the actual page request was it's difficult to comment. Personally I see a lot of sql errors caused by 'hacking attempts' although I suspect this one may simply be the bot blindly creating all possible combinations of links from a page and getting some simply wrong.

The next day, I received another email with the same message but different seemingly random order clause.
Is it unavoidable? Is it harmless? Would prefer not receiving those kind of messages.

A fix might be to augment the logic to check for valid "order by" values and return 404 on a bad request such as these.

        1. ERROR CODE: Errno: 1054 Message: Unknown column 'lc.gmap_id' in 'order clause'
Its clear these are bugs. Indeed, there isn't any column gmap_id in the bwliberty_content table. Filed a report.
