左加入hibernate

Question

我试图在hibernate查询下运行。但它给我一个错误，因为＆＃34; org.hibernate.QueryException：外部或完全连接必须后跟路径表达式＆＃34;

有人可以告诉我这个查询有什么问题吗？

select P from Package P left join PkgBid PB 
where P.pid = PB.pid 
and P.bemsid = 2148862 
and P.packagestatus= 1 
and PB.pid is null 
order by P.pid

Answer 1

您的加入需要on条款。确切的语法取决于您的实现，但可能类似于：

select P.*
from Package P
left join PkgBid PB 
    on P.pid = PB.pid 
where P.bemsid = 2148862 
and P.packagestatus = 1 
and PB.pid is null 
order by P.pid
