我有这个查询,我一直在试图找出如何转换为LINQ:
select bjbecd, bjbesk, areotx
from insku
inner join iniwre on bjcomp=a7comp and bjbecd=a7becd and bjbesk=a7besk
inner join initem on bjcomp=arcomp and bjbecd=arbecd
where a7comp=1 and
a7wcde in (1,10) and
a7ohdq>0 and rtrim(a7becd) + rtrim(a7besk) not in
(select skucode from eoditems)
到目前为止,这是我的LINQ:
(from i in db.INSKUs
join w in db.INIWREs on
new { i.BJCOMP, i.BJBECD, i.BJBESK }
equals
new { w.A7COMP, w.A7BECD, w.A7BESK }
join t in db.INITEMs on
new { i.BJCOMP, i.BJBECD }
equals
new { t.ARCOMP, t.ARBECD }
where w.A7COMP == 1
where w.A7WCDE == 1 || w.A7WCDE == 10
where w.A7OHDQ > 0
where !(from z in db.EODItems
select z.SkuCode).Contains(w.A7BECD.TrimEnd() + w.A7BESK.TrimEnd())
select new { i.BJBECD, i.BJBESK, t.AREOTX }
);
我在第一次连接时收到一条错误消息,指出“join子句中某个表达式的类型不正确。在'Join'调用中类型推断失败。”
我所做的所有搜索都与类型匹配错误有关,但是我在联接中检查了所有类型的四倍,它们是相同的。
答案 0 :(得分:5)
尝试做这样的事情:
join w in db.INIWREs on
new { i.BJCOMP, i.BJBECD, i.BJBESK }
equals
new { BJCOMP = w.A7COMP, BJBECD = w.A7BECD, BJBESK = w.A7BESK }
应该工作。
