我正在做以下事情,得到“1”我认为这意味着声明很好.但我想取而代之的是结果.
怎么了？
#!/usr/bin/perl use strict; use DBI; my $host = "test"; my $database = "dd"; my $port = 3306; my $user = "uuu"; my $pw = "ppp"; my $MysqL = DBI->connect("DBI:MysqL:database=$database;host=$host;port=$port",$user,$pw) or die "Cannot connect to MysqL server\n"; my $m = $MysqL->do(qq{select MAX(idvisit) from log_visit}); print $m;
解决方法
my $m = $MysqL->selectrow_array(qq{select MAX(idvisit) from log_visit});
