根据MySql中的两列删除重复记录

Question

我想删除多余的重复记录

即。在显示的图片中有两条记录corporate_id = 5和category_id = 19，如何删除任何一行重复（此处corporate_sed_id是主键）

Answer 1

使用： -

DELETE
FROM
    corporate
WHERE
    corporate_sed_id IN(
    SELECT
        *
    FROM
        (
        SELECT
            MIN(corporate_sed_id)
        FROM
            corporate
        GROUP BY
            corporate_id,
            category_id
        HAVING
            COUNT(corporate_sed_id) > 1
    ) temp
)
