Hi all,
I'm a little confused about my little mod_perl web site at the moment.
I'm doing an SQL query, then punting the results into a dataset to
display via the web page.
When I do the query directly on the SQL server, I see:
SELECT COUNT(*) FROM printers;
30
When I do the same in code via the web page, I get:
$sth = $dbh->prepare("SELECT COUNT(*) FROM printers");
$vars->{"count"} = $dbh->selectcol_arrayref($sth, undef);
'count' => [ 29 ]
Even trying a slightly different approach:
$sth = $dbh->prepare("SELECT COUNT(*) FROM printers");
$sth->execute();
$vars->{"count"} = $sth->fetchrow_hashref();
count' => { 'COUNT(*)' => 29 }
This table is only ever updated manually - so there is no possible way
that the contents are being updated during these runs - however I also
note that the data returned in something like `SELECT * FROM printers`
is different than what I get by running the query directly.
Annoyingly, even after restarting apache, restarting mariadb, and even
restarting the entire machine, I still see this issue.
That leaves me completely stuck - how can old data be returned - even
after a full machine reboot?
Am I missing something kinda obvious?
The system is Fedora 37 with the following versions:
mariadb-10.9.4-1
mod_perl-2.0.12-5
httpd-2.4.54-5
perl-DBD-MariaDB-1.22-3
perl-DBD-MySQL-4.050-15
I've tried both the dbi:mysql and dbi:MariaDB - and the same occurs.
