 根据template_id 做过滤 ↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓

SELECT
    *
FROM
    (
        SELECT
            CONCAT(user_id, '_', doctor_id) u_d,
            GROUP_CONCAT(template_id) str
        FROM
            treatment_log
        GROUP BY
            user_id,
            doctor_id
    ) t

1.查询包含5 但不包含2 的分组数据

SELECT
    *
FROM
    (
        SELECT
            CONCAT(user_id, '_', doctor_id) u_d,
            GROUP_CONCAT(template_id) str
        FROM
            treatment_log
        GROUP BY
            user_id,
            doctor_id
    ) t
WHERE
    LOCATE('2', t.str) = 0
AND LOCATE('5', t.str) > 0

结果:

2.查询只包含1的分组数据

where t.str = '1'

结果：
