SQL中删除同一字段中重复的值_MySQL

/////////////////////目地：ZDJZ_DIS中 name字段有重复的值，删除重复的值DELETE *FROM ZDJZ_DISWHERE NAME  IN (select NAME from ZDJZ_DIS group by NAME having count(NAME) >1);上面的做法会删除掉所有的相同的值，包括你想要的，只要重复就删除 DELETE *FROM ZDJZ_DISWHERE ID  in (select min(ID) from ZDJZ_DIS group by NAME having count(NAME)>1);1有没有重复的某项值  2如果有的话，选择ID最小的那个 结合起来DELETE *FROM ZDJZ_DISWHERE NAME  IN (select NAME from ZDJZ_DIS group by NAME having count(NAME) >1)and ID not in (select min(ID) from ZDJZ_DIS group by NAME having count(NAME)>1);
