org.hibernate.hql.internal.ast.QuerySyntaxExceptionunexpected token: on near line 1

select d.content,count(s.status) from MesmachineStatus s , Mesmachinestatusdetail d where s.status=d.status group by s.status 正确地 

SELECT d.content,count(s.status)from Mes_machinestatus s left JOIN mes_machinestatusdetail d  on s.status=d.status GROUP BY s.status 错误的 

hql 不支持 left join on   要改成where 就可以了
