Hi Monks
I am doing kind of session management for my client server based application. I use Perl DBI + SQLite to store the data into DB. I have following code,
...
$self->_loggerObj()->logInfo("Cleanup Corpse sessions from DB: ".$se
+lf->_sessionsDBFName());
# Prepare delete query to clean up corpse
try
{
#Delete all the sessions where Sessions original creation time
+ + SESSION_MAX_LIFE_TIME < NOW
$stHandle = $dbHandle->prepare( qq{
DELETE FROM TB_SESSIONS WHE
+RE ( TB_SESSIONS.creationTime + ? ) < ? ;
} );
}catch
{
$self->_loggerObj()->logError("Can not PREPARE Corpse clean up
+ DELETE for DB: ".$self->_sessionsDBFName()." , ".$dbHandle->errstr()
+.", $_ , in removeSessionDetails");
$dbHandle->disconnect();
undef $stHandle;
undef $dbHandle;
#Here the main operation is success , Corpse clean up is extra
+, do not report error from Corpse clean up, Just return main operatio
+n
# i.e removeSessionDetails's result.
return SESSION_ID_REMOVED;
};
#Run query
try
{
$self->_loggerObj()->logInfo("Execute :Corpse clean up DELETE
+from DB [removeSessionDetails]".SESSION_MAX_LIFE_TIME." ".time());
$dbHandle->do('BEGIN EXCLUSIVE TRANSACTION');
my $now = time();
print "\n NOW: $now";
my $rv = $dbHandle->do('DELETE FROM TB_SESSIONS WHERE ( TB_SES
+SIONS.creationTime + '.SESSION_MAX_LIFE_TIME.' ) < '.$now.';');
print "\n ---1.", Dumper($rv);
$rv = $stHandle->execute(SESSION_MAX_LIFE_TIME,time());
print "\n ---2.", Dumper($rv);
$dbHandle->do('COMMIT TRANSACTION');
}catch
{
$self->_loggerObj()->logError("Can not RUN Corpse clean up DEL
+ETE query for DB: ".$self->_sessionsDBFName()." , ".$dbHandle->errstr
+().", $_ , in removeSessionDetails");
$dbHandle->disconnect();
undef $stHandle;
undef $dbHandle;
#Here the main operation is success , Corpse clean up is extra
+, do not report error from Corpse clean up, Just return main operatio
+n
# i.e removeSessionDetails's result.
return SESSION_ID_REMOVED;
};
....
Essentially I am trying to remove dead sessionIDs. I expect same output for both prints but I got following output,
NOW: 1373630196
---1.$VAR1 = '0E0';
---2.$VAR1 = 4;
According to my logic, I expect '0E0' , first query output is correct. This is want I want but when I pass the same arguments via prepare + execute, code is not doing what i want. Am I making some stupid mistake??
