mysql - mysql分组返回结果

Question

我有下表

table x

labref   name  repeat_status
111      L          1
111      L          1
111      K          1
111      K          1
111      L          2
111      L          2
111      M          1
111      M          1

我需要的结果是

labref   name  repeat_status
111      L          1
111      L          2
111      K          1
111      M          1

我已经尝试过这个查询，但它没有带来结果，需要调整

SELECT name, repeat_status
FROM `x`
WHERE labref = '111'
GROUP BY repeat_status;

建议！
