create algorithm=temptable view aj as select
sporter.sporter_id,name,grade.itemid,itemname,mark from sporter inner join grade on
sporter.sporter_id=grade.sporter_id
inner join item on item.itemid=grade.itemid
where location='一操场';

mysql> select * from aj;
ERROR 1267 (HY000): Illegal mix of collations (utf8_general_ci,IMPLICIT) and (gbk_chinese_ci,COER
CIBLE) for operation '='
