如何将 concat/append 多个返回行合并为一行？

Question

我想查询 return 这个结果：

+-----------------------------------------+
| product_english                         |
+-----------------------------------------+
| can of orange juice                     |
| oatmeal container                       |
| milk bottle 28 oz                       |
| chocolate powder no sugar added - 16 oz |
| instant coffee 8 oz container           |
| almonds bag 25 oz.                      |
+-----------------------------------------+

如您所见，总共 return 6 行。

我想return所有记录只在一行中。这可能吗？

下面是更好地可视化事物的查询：

SELECT product_english
FROM menuBreakfast mb
JOIN productPerMenu ppm ON ppm.menu_id = mb.breakfast_id
JOIN productList pL on ppm.product_id = pL.product_id
WHERE breakfast_id = 'B1';

提前致谢。

Answer 1

SELECT GROUP_CONCAT(product_english ', ')
FROM menuBreakfast  
WHERE breakfast_id = 'B1';

你也可以申请concat

SELECT concat(product_english ) as product_english FROM menuBreakfast  
WHERE breakfast_id = 'B1';
