在一个查询中使用MySQLI计算总用户数和家族数

Question

我希望从我的数据库返回2值，

这是我在2个查询中所做的：

$con = mysqli_connect("127.0.0.1",$user_database,$password_database,$nama_database) or die(" User atau Password Database tidak Valid ");
$select_total_user=mysqli_fetch_array(mysqli_query($con, "SELECT count(`acct_username`) from `pvpgn_BNET`"));
$total_user=$select_total_user[0];
$select_total_clan=mysqli_fetch_array(mysqli_query($con, "SELECT count(`name`) from `pvpgn_clan`"));
$total_clan=$select_total_clan[0];

我想要返回的值是Total Users和Total Clans 在单个查询中 感谢

Answer 1

在单个查询中，可以像

一样完成

select
( SELECT count(`acct_username`) from `pvpgn_BNET`) as total_user,
( SELECT count(`name`) from `pvpgn_clan` ) as total_clans ;

您可以按索引名total_user和total_clans

执行查询和获取数据

Answer 2

select count(acct_username) AS c1, count(name) AS c2 FROM `pvpgn_BNET`, `pvpgn_clan`;
