update table in oracle db	Can't Post

I have the function below that is supposed to update an existing table. I do not get any errors when I execute the script, however when I go back and try to verify that the update was successful, the entry is not in the table. I am connecting to an oracle database using the DBI module.

Thanks

sub update_cmds {

my $name = shift;

my $value = shift;

my $sth = undef;

my $sql_statement = "UPDATE SET_CMDS SET SET_VALUES=\'$value\', LAST_ACK_TIME=NULL WHERE SET_NAME=\'$name\' ";

unless ($sth=$dbh->prepare($sql_statement)) {

$dbh->rollback;

log_off_oracle($dbh);

exit;

}

unless ($sth->execute()) {

$dbh->rollback;

log_off_oracle($dbh);

exit;

}

}

Try to check your AutoCommit property in your code.

Code

my $dbh = DBI->connect( "dbi:Oracle:$db", $username, $passwd ) ||           die( $DBI::errstr . "\n" ); 
$dbh->{AutoCommit}    = 0;

AutoCommit: when set to 1, DBI issues a commit after each successful SQL statement. This is very dangerous and on by default. Setting it to 0 is a good idea.
If you set it to '0' then you need to commit every successful SQL statement.
