If I recall correctly, when I used Sybase (about 12 years ago) I used to do it like this:
my $SQL = <<EOSQL;
begin
insert into foo (col1, uniquecol) values (?, ?);
select id from foo where uniquecol=?;
end
EOSQL
my $ST = $DB->prepare($SQL);
$ST->execute('abacus', 'S/N5842', 'S/N5842');
while (my $hr = $ST->fetchrow_hasharray) {
print "ID is $$hr{ID}\n";
}
Since it's executed in a transaction, there isn't a race condition. However, you *do* need to be able to uniquely identify the row without using it's ID--by using a unique (group of) column(s).

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).
