Thanks again, Simon, I am using ubuntu 9.04. I installed sqlite3 by using apt-get install sqlite3 and got sqlite3 version 3.6.10. I have not updated sqlite from version 3.6.10 to version 3.6.12 yet. 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 $ zcat hq.dump.gz | sqlite3 hq3.db Then, I did pragma integrity_check and vacuum on the new database. Before I ran vacuum, the pragma integrity check returns OK. After I ran vacuum, I still got errors when I ran pragma integrity_check. Also, the number of rows of table firmsret11 reduces to 2. $ sqlite3 hq3.db SQLite version 3.6.10 Enter ".help" for instructions Enter SQL statements terminated with a ";" sqlite> pragma integrity_check; ok sqlite> vacuum; sqlite> select count(*) from firmsret11; 2 sqlite> pragma integrity_check; *** in database main *** On tree page 19 cell 20: Child page depth differs On tree page
