復制代碼 代碼如下:

#! /usr/bin/perl
use DBI;
my $driver="DBI:mysql";
my $database="perl_test";
my $user="root";
my $host="localhost";
my $passwd="root";
my $rules="alert_rules";
my $dbh = DBI->connect("$driver:database=$database;host=$host;user=$user;password=$passwd")
or die "Can't connect: " . DBI->errstr;
my $sth=$dbh->prepare("select app_name,receivers from $rules ");
$sth->execute() or die "Can't prepare sql statement". $sth->errstr;
my $sth=$dbh->prepare("select app_name,receivers from $rules ");
$sth->execute() or die "Can't prepare sql statement". $sth->errstr;
# 打印獲取的數據
while(@recs=$sth->fetchrow_array){
print $recs[0].":".$recs[1]."/n";
}
$sth->finish();
$dbh->disconnect();
