MySQL 提供精确的预先指定的 ORDER BY 子句

Question

我将如何执行以下查询:

SELECT
    *
FROM
    main_items
WHERE 
    group_id IN ('985ce7', 'fc154', 'f387cd', 'd3d27')
GROUP BY
    group_id 
ORDER BY                                   
    ('985ce7', 'fc154', 'f387cd', 'd3d27') # this is the line I'm referring to

基本上，我希望按照我上面指定的确切顺序订购商品。我该怎么做？

Answer 1

尝试以下任一方法:

ORDER BY FIELD(group_id, '985ce7', 'fc154', 'f387cd', 'd3d27')

或

ORDER BY FIND_IN_SET(group_id, '985ce7,fc154,f387cd,d3d27')

如果 group_id 的值包含逗号，则第一个选项将成为唯一选项。
