AND b.positiontype in(SELECT b.positiontype applypositiontype FROM teach_applyposition b group by b.positiontype having count(b.positiontype)>1) GROUP BY appposiid ORDER BY sort,a.positiontype,a.mastersort,b.positiontype

SELECT b.positiontype applypositiontype FROM teach_applyposition b group by b.positiontype having count(b.positiontype)>1的结果是
