我有工作,但實在是太慢了下面的查詢,因爲它是採用:休眠刪除與連接而不需要使用
_session.CreateQuery(@"
delete OrderItem oi
where oi in
(select i
from OrderItem i
where i.Product.Id = :productId
and i.Order.Company.Id = :companyId
and i.Order.Campaign.Id :campaignId
and i.Order.OrderStatus = :orderStatus)
")
.SetParameter("productId", productId)
.SetParameter("companyId", companyId)
.SetParameter("campaignId", campaignId)
.SetParameter("orderStatus", orderStatus)
.ExecuteUpdate();
有沒有辦法使用,你可以簡單地使用連接本機查詢方式刪除像:
DELETE posts
FROM posts
INNER JOIN projects ON projects.project_id = posts.project_id
WHERE projects.client_id = :client_id
