3.6.10 was January 2009. 9 months ago. Perhaps there's an easy way to get a later version. > But, I have tried .dump by following the instructions on > <http://www.sqlite.org/sqlite.html>. > > I created a new database by using > $ echo '.dump' | sqlite3 hq.db | gzip -c > hq.dump.gz Unzip the .gz file into a text file and look through it. See if you can see anything strange about it, especially in table firmsret11.

I think you have come up against one of the known bugs in 3.6.10. But I don't know enough about SQLite to be sure. However, I'd recommend you update just in case the bug I'm thinking of, or a later bug is causing your problem. And anyone trying to cure your bug will definitely want to start from the current version of SQLite, not one nine months old.
