How do you know it has data inside it ? A common mistake is to try to write to
databases in the read only part of an application's sandbox on the iphone.
Where in the sandbox is the database ?

You don't check the return codes here properly. sqlite3_prepare_v2() can
return SQLITE_BUSY, or SQLITE_SCHEMA, or SQLITE_MISUSE. More importantly, you
don't check if sqlite3_step() returns SQLITE_DONE which would indicate that you
have 0 rows in this table.
