mysql 如何将两条sql的结果合并到一列，

想要达到这样的效果
两条sql 只有一个 card.type 条件不一样 0,于1 的区别 , 最后希望结果等于
comp.comp_info_id,
comp.comp_name,
card.school_info_id,
count(card_info_id) stu ，
count(card_info_id) tea
第一条s'q'l
SELECT
comp.comp_info_id,
comp.comp_name,
card.school_info_id,
count(card_info_id) stu

FROM
t_comp_info comp
LEFT JOIN t_card_info card ON comp.comp_info_id = card.school_info_id
AND card.state = 2 AND card.type = 0
WHERE
comp.state = 1
GROUP BY
comp.comp_info_id
ORDER BY count(1 )

    第二条sql 

SELECT
comp.comp_info_id,
comp.comp_name,
card.school_info_id,
count(card_info_id) tea

FROM
t_comp_info comp
LEFT JOIN t_card_info card ON comp.comp_info_id = card.school_info_id
AND card.state = 2 AND card.type = 1
WHERE
comp.state = 1
GROUP BY
comp.comp_info_id
ORDER BY count(card.card_info_id ) desc

把两个查询作为子查询关联起来，用他们相同的字段 oncode 作为连接条件来关联

添加一个辅助列，比如 cc = 1 然后 join on cc

如果查询结果一样，试试union all
