MySQL: Select multiple records in one line

Question

In a query like this one:

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

My results are displayed like so:

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

How do I write my SQL statement, to get a result like this one?:

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

Answer 1

Use GROUP_CONCAT

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

Answer 2

Try this:

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

• GROUP_CONCAT(expr)
