MySQL选择将同一表中的多行分组

我试图创建一个查询，从同一个表中选择多行，将它们像数组一样分组。现在我使用php来选择它们，如下所示：

$tks = mysqli_query($con,"SELECT * FROM hof ORDER BY tks DESC LIMIT 5");
$top_ths = mysqli_query($con,"SELECT * FROM hof ORDER BY ths DESC LIMIT 1");
$top_tha = mysqli_query($con,"SELECT * FROM hof ORDER BY tha DESC LIMIT 1");
----

我想把它们合并到一个查询中，这样我就得到了一个关联数组。类似这样的东西：

(SELECT * FROM hol ORDER BY tks DESC LIMIT 5) AS tks
UNION
(SELECT * FROM hol ORDER BY ths DESC LIMIT 1) AS top_ths

所以tks包含所有5行，top_ths包含1行。有可能吗？谢谢
