I would try doing this:
my $sqlString = 'delete from %s;';
$dbh->begin_work;
my @tables = ('table1','table2','table3');
foreach my $table (@tables) {
my $sth = sprintf($sqlString, $table);
$dbh->do( $dth );
}
$dbh->commit;
This would speed it up some, but double-check the DBI doco on cpan for the 'begin_work' function before you do it on how it will react since I think it depends on the database you use and whether it supports transactions or not.
The last thing you could try could be a drop/create where you basically drop the old table and re-create it from scratch... That will definately speed it up, but some people get twitchy when doing it :)
Something like
$dth->do("drop table0");
$dth->do("create table0 ( col1 def, col2 def.....)");
etc....

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).
