Hi Juerd. I was playing around with your code using the
following MySQL database table:
+-------------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+-------------+------+-----+---------+-------+
| id | int(11) | YES | | NULL | |
| name | varchar(64) | YES | | NULL | |
| description | varchar(64) | YES | | NULL | |
+-------------+-------------+------+-----+---------+-------+
and the following client code:
use strict;
use warnings;
use DBI;
my $dbh = DBI->connect( ... );
use transactions $dbh;
$dbh->do('delete from foo');
transaction {
for (1..10) {
my $sth = $dbh->prepare('insert into foo values(?,?,?)');
$sth->execute($_, chr(ord('a')+$_), chr(ord('z')-$_));
rollback if $_ == 5;
}
};
print map "@$_\n", @{$dbh->selectall_arrayref('select * from foo')};
$dbh->disconnect;
__END__
results:
1 b y
2 c x
3 d w
4 e v
5 f u
I honestly expected there to be no output ... shouldn't
a rollback cause all 'inserted' data to be 'undone'?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
