ALTER TABLE common_member CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

最佳答案

進(jìn)入數(shù)據(jù)庫，執(zhí)行語句：
select uid from pre_ucenter_members where username in (select username from pre_ucenter_members group by convert(username using utf8mb4) collate utf8mb4_unicode_ci having count(1) > 1)
再將異常用戶改名
，如果UC表查詢無異常，上述語句中表名可以更換為（pre_common_member）
