一、查询语句上加binary
SELECT a.DOCU_CODE '单一窗口编号', b.DOCU_CODE '本地编号',a.DOCU_NAME '单一窗口名称',b.DOCU_NAME '本地名称' from licensedocu a,licensedocu_copy b where binary a.DOCU_CODE = b.DOCU_CODE and a.DOCU_NAME != b.DOCU_NAME
二、建表时加binary
create table t { code varchar(10) binary }
ALTER TABLE t_order CONVERT TO CHARACTER SET utf8 COLLATE utf8_bin;
