How to write this linq query with Criteria or QueryOver API

由 ﹥＞﹥吖頭↗ 提交于 2019-11-28 05:37:28
问题 Is it possible to convert this code at below, written by using Query(linq) api to Criteria or QueryOver API in NHibernate? I'm using this to format data into DTO's also it works with just one round-trip to db. Note: I tried transformers.aliastobean but I can only use one transformer at a time. Is it possible to use multiple transformer in one query? from entityType in Provider.GetSession().Query<crmEntityType>() .Fetch(x => x.Association) .Fetch(x => x.Fields) .AsEnumerable() where

Adding conditions to outer joins with NHibernate ICriteria/QueryOver query

由 强颜欢笑 提交于 2019-11-28 02:06:59
问题 Is there a way to specify additional conditions on outer joins in NHibernate when querying using QueryOver or ICriteria? I need some extra conditions on the outer join-ed table, but NHibernate always adds them to the WHERE clause at the end - which does not get the correct behaviour (see http://weblogs.sqlteam.com/jeffs/archive/2007/05/14/criteria-on-outer-joined-tables.aspx). I can't seem to find any way to do this using Criteria or the QueryOver syntax... Thanks 回答1: You probably figure out

I'm trying to create a rowcount-query from a regular query, but the resulting SQL seems to lack the GROUP BY resulting in a wrong count. Does anyone know what I'm doing wrong. First the queries: var query = Session.QueryOver<InkoopFactuurListItem>() .Where(i => i.KlantId == Klant.Id) .AndRestrictionOn(i => i.Status).IsIn(statussen) .SelectList(list => list .SelectGroup(h => h.Id).WithAlias(() => dto.Id) .SelectGroup(h => h.Banknummer).WithAlias(() => dto.Banknummer) .SelectGroup(h => h.CrediteurNaam).WithAlias(() => dto.CrediteurNaam) .SelectGroup(h => h.DienstType).WithAlias(() => dto

问题 I'm in the process of learning QueryOver, but I can't for my life figure out how to do simple many to many queries.

Basically I have Product > ProductCategory < Category ProductCategory just has ProductId / CategoryId, and I'm trying to select all the products in a

queryover and (x like 'a' or y like 'a')

Hi Is there any elegant way of combining 'like' and 'or' when i'm using queryover API? for 'like' there is something like: query.WhereRestrictionOn(x=>x.Code).IsLike(codePart) for 'or' i can do something like: query.Where( x=>x.Code == codePart || x.Description== codePart) but how can I create a query like this: select * from n where code like '%abc%' or description like '%abc%' query.Where(Restrictions.On<Type>(x => x.Code).IsLike(codePart) || Restrictions.On<Type>(x => x.Description).IsLike(codePart)) You could use the NHibernate Disjunction class to do this in a more elegant (IMHO) fashion:
