mysql将多条结果拼接成一条结果

1,实际数据

SELECT resource_id, resource_type FROM res_resource_mount 

2,拼接之后数据

SELECT
    c.resource_id,
    GROUP_CONCAT(c.resource_type)
FROM
    (
        SELECT
            resource_id,
            resource_type
        FROM
            res_resource_mount 
    ) c
GROUP BY
    c.resource_id
