Entity Framework 5, Code First, Full Text Search but IQueryable via CreateQuery?

由 旧巷老猫 提交于 2019-12-12 16:01:49
问题 I am using .NET 4.5 and EF 5 with Code First approach and now I need to implement Full Text Search. I have already read a lot about it and so far my conclusions are: Stored procedures nor Table Value Functions can not be mapped with Code First. Still I can call them using dynamic sql dbContext.Database.SqlQuery<Movie>(Sql, parameters) But this returns IEnumerable and I want IQueryable so that I can do more filtering before fetching the data from db server. I know I can send those parameters

hibernate中只选取某些列的写法

由 喜欢而已 提交于 2019-12-09 13:59:06
在普通的sql中，为了选取某些列，其实是很简单的，就select 列名就可以了，但在hibernate中，一般 都是sql="from user ....";但这样其实某些时候，效率还是很低的，在hibernate做的时候，要这样了，如下： String hql="select new map(t.title as title,t.id as id,t.link as link,t.linktitle as linktitle) from Article as t where t.category="+categoryid+" order by t.uploadtime desc"; Query query= getSessionFactory().getCurrentSession().createQuery(hql); query.setFirstResult((pageNo - 1) * pageSize); query.setMaxResults(pageSize); List<Map> list = query.list(); for(Map article : list) { String title = (String)article.get("title"); System.out.println("文章标题是"+title); } 下面再介绍下相关的知识： 1

Can't find CreateQuery() method

I'm a new beginner to the entity framework . and i can't find the following method CreateQuery() why i can't find this method ?!! Since ESQL was considered an advanced use case, there is no straightforward API from DbContext . You can access the ObjectContext that backs your DbContext to do what you want: ((IObjectContextAdapter)context).ObjectContext.CreateQuery<Person>("esql..") Related: http://thedatafarm.com/blog/data-access/accessing-objectcontext-features-from-ef-4-1-dbcontext/ As suggested there, you can also add a method ( or property) ObjectContext to your context class: public class

Is there possible to use createQueryBuilder for insert/update? If not, what function should I use?

由 主宰稳场 提交于 2019-11-27 12:28:02
问题 For now I succeded to create a function that retrieves data from the database using Doctrine's function createQueryBuilder. Does anybody know if there is a similar function to insert or update the database? Or how can i use createQueryBuilder? 回答1: Doctrine 2 ORM does not support INSERT via DQL or the DQL query builder. For a complete syntax, check the EBNF of DQL. To handle inserts in ORM, you always manually instantiate an entity and persist it with the entity manager: $user = new \My
