Perl, MySQL and the work done

[mogul]

I'm using DBI to access a MySQL database. I do updates.

Is it possible to get both the number of rows matched and the number of rows changed? The MySQL CLI easily reports both like:

Rows matched: 1  Changed: 0  Warnings: 0

I have tried to change mysql_client_found_rows, but that only let me choose which one I get. I need both!

I think you want $info = $dbh->{'mysql_info'}; I don't have anything to test it, but I assume it maps to this: http://dev.mysql.com/doc/refman/5.0/en/mysql-info.html

#!/usr/bin/perl
use warnings;
use strict;

use Data::Dumper;
use DBI;

my %attr = (
    'RaiseError' => 1,
    'FetchHashKeyName' => 'NAME_lc',
    'AutoCommit' => 0,
    'mysql_enable_utf8' => 1,
);
my $dbh = DBI->connect("dbi:mysql:database=xxx_db;host=127.0.0.1;port=
+3306", 'xxxx_db', 'xxxxx', \%attr);
$dbh->do('drop table if exists mca_test');
$dbh->do('create table mca_test (field varchar(20))');
$dbh->do("insert into mca_test(field) values ('sepp')");
$dbh->do("insert into mca_test(field) values ('kuno')");
$dbh->do("insert into mca_test(field) values ('seppl')");
$dbh->commit;
my $sql = "update mca_test set field = 'seppl' where field like 'sepp%
+'";
my $num = $dbh->do($sql);
print Dumper($dbh->{'mysql_info'}), "\n";
print "Rows: $num\n";

$dbh->commit;
$dbh->do('drop table if exists mca_test');
$dbh->disconnect;

$dbh->{'mysql_info'}; seems to work for me, test code below, credit to kschwab for pointing this out

use strict;
use warnings;

use DBI;

my $database = 'test';

my $dsn = "DBI:mysql:$database;mysql_read_default_file=$ENV{HOME}/.my.
+cnf";
my $dbh = DBI->connect($dsn,undef,undef,{ RaiseError => 1 });

$dbh->do("update foo set bar=1");

my $info = $dbh->{'mysql_info'};

my ( $matched, $changed, $warnings ) = $info =~ /Rows matched: (\d+)  
+Changed: (\d+)  Warnings: (\d+)/;

print "Matched: $matched\nChanged: $changed\nWarnings: $warnings\n";
