Well I tried with DBD-SQLite-1.27 initially and ran into the problem. I
then removed it and installed DBD-SQLite2-0.33 so I only have 1

I understand that the sqlite versions are incompatible but I thought I
was using only 1 at a time.
Are you saying that DBD-SQLite-1.27 can do both v2 and/or v3? How do I
tell it which to use?
DBD-SQLite-1.27 can do *only* SQLite v3 databases.
Also note that the problem ONLY occurs when the script is accessed via
mod_perl from the apache webserver. If I run it (using DBD-SQLite-1.27)
from the command line it all works perfectly. Something is different
when run via the webserver.
The reason I mentioned the v2/v3 incompatibility was because you said you used
both DBD::SQLite2 (v2) and DBD::SQLite (v3), and your example code was SQLite2.
Make sure you are using just DBD-SQLite2-0.33 *or* DBD-SQLite-1.27 in all places
for the same database, and make sure you create the database file with the same
version as all places you are using it.
Make sure that the Perl you are running in mod_perl is the same one as you're
running on the command line or that both have the same DBD::SQLite.
To help troubleshoot, first put your old database aside, then make sure your
programs are all using the same DBD::SQLite, then create a *new* database using
one of those and make sure both can use it without problems. After this is all
known to be working, *then* try to use your older/existing database, and if the
problem returns then the database may be incompatible with the DBD::SQLite you
have installed.
If you have a choice, use just DBD-SQLite-1.27 and *not* DBD-SQLite2-0.33; the
latter is a legacy project and the former is the new version that everyone
should use given a choice.
If your existing SQLite database has important data, it can be converted to the
SQLite 3 if it is SQLite 2, so you can have your whole system current.

Mike, off-hand it looks like you're trying to use SQLite 2.x and
SQLite 3.x on the same database. You can't do this as these 2 SQLite
major versions are incompatible with each other, with different file
formats, and SQLite 3 won't work with SQLite 2 files. Make sure you
are using just DBD::SQLite2 (SQLite 2) or DBD::SQLite (SQLite 3) with
the same database on both the command-line and in your web app. Note
that the reason the DBD::SQLite which does SQLite v2 and v3 have
different Perl package names is so that you can use both in the same
program at once, if you wanted to such as to do a conversion, though
for conversion using the SQLite command-line utility for dump and then
load works well, perhaps best, also. -- Darren Duncan

I've developed a small app that uses a webpage to insert/delete data
into a sqlite database. The script work find when I run them from the
command line but not when run from the webpage.
For example, using the following code:
$db =
DBI->connect("dbi:SQLite2:dbname=/home/oracle/bugpush/bugpush.db",
"", "", { RaiseError => 1, AutoCommit => 1 }) || die( $DBI::errstr .
"\n" );
$sth = $db->prepare("select api_key, bugno, last_update_date, analyst
from tracked_bugs order by bugno");
if(! defined($sth) || ! ($sth)) {
print "Failed to prepare SQL statement:\n";
print "$DBI::errstr\n";
goto END;
}
In the apache error_log I see the following:
[Tue Dec 01 06:49:21 2009] [error] DBD::SQLite::db prepare failed:
not an error
at /home/oracle/bugpush/tracking.cgi
Oddly enough if I use the DBD::SQLite2 module this works just fine
(although the underlying db that is created is sqlite v2.x).
I have verified that this is not a permission problem as I have
copied the database file to /tmp/bugpush.db and set the permissions
as 777 but still get the same result.
Any ideas as to why this is failing to run with DBD-SQLite-1.27 but
works fine with DBD-SQLite2-0.33?
