下例为如何使用KingbaseES Perl DBI 建立与KingbaseES数据库的连接以及获取结果集：
#!/usr/bin/perl
use DBI;
use DBD::KB;
printf("before connect\n");
$dbh = DBI->connect("DBI:KB:dbname=TEST;host=192.168.4.8", 'SYSTEM',
'MANAGER');
printf("after connect\n");
$sth = $dbh->prepare("select 123 as a, 456 as b");
$sth->execute();
while(@row = $sth->fetchrow_array())
{
print "row = @row\n";
}
