mysql - 如何在IN

Question

我有一个名为JSON的{​​{1}}列的表格。我使用它存储和数组，现在我想在related内使用这个数组。我怎么能这样做？

e.g。 IN

和SELECT * FROM products WHERE id IN (select related FROM products WHERE id = 1);返回SELECT related FROM products

Answer 1

您可以使用功能

更新2 :(已测试）：

SELECT
`id`,
`related`
 FROM
`products`
 WHERE
    JSON_SEARCH((SELECT `related` FROM `products` WHERE `id` = 4) ,'one', `id`)
             IS NOT NULL;
