Question

我有以下表

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 

，我需要的是

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

我曾嘗試此查詢，但它並沒有帶來結果的結果，需要調整

返回的結果

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