Question

在像这样的查询中：

SELECT * 
FROM `Keywords`
WHERE `Page` = 'food'

我的结果显示如下：

| Page   | Keyword |
--------------------
| food   | Pizza   |
--------------------
| food   | Burger  |
--------------------
| food   | Sushi   |
--------------------

如何编写我的SQL语句，以获得类似这样的结果？：

| Page | Keyword              |
-------------------------------
| food | Pizza, Burger, Sushi |
-------------------------------

Answer 1

使用GROUP_CONCAT

SELECT `Page`, GROUP_CONCAT(`Keyword` SEPARATOR ', ') AS 'foods'
FROM `Keywords` 
WHERE `Page` = 'food'
GROUP BY `Page`;

Answer 2

试试这个：

SELECT page, group_concat(Keyword separator ', ') as myList
FROM 'Keywords'
WHERE `Page` = 'food'
GROUP BY Keyword;

另见：

MySQL：在一行中选择多个记录
