MySQL從同一表中選擇對多行分組

Question

我正在嘗試創建一個查詢，以從同一張表中選擇多行，將它們像一個數組一樣分組。 現在，我使用php這樣選擇它們：

$tks = mysqli_query($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");

----

我想將它們合並在一個查詢中，以便得到一個關聯數組。 像這樣：

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

因此tks包含所有5行，而top_ths包含1行。 可能嗎 ？ 謝謝。

Answer 1

從最下面的組行開始，添加其他字段

(SELECT *, 1 as `group` FROM hol ORDER BY tks DESC LIMIT 5)
UNION
(SELECT *, 2 as `group` FROM hol ORDER BY ths DESC LIMIT 1)
