createcriteria

I have a problem similar to this . But I want a does not contain functionality. Like I have a Post domain. A Post hasMany User. What I'd like to do, using createCriteria, is something like this: def c = Post.createCriteria() def l = c.list (max: maxVar) { notContains("users", thisUser) } I tried using ne But no luck. def l = c.list (max: maxVar) { users { ne('id', thisUser.id) } } To be clear, how can I get list of all the Post whose users field which is a collection does not contain thisUser ? You can use HQL for this List<Post> posts = Post.executeQuery("select distinct p from Post p where

How can I write the following SQL using CreateCriteria: SELECT * FROM FooBar fb WHERE EXISTS (SELECT FooBarId FROM Baz b WHERE b.FooBarId = fb.Id) Here is how you can do it: var fooBars = Session.CreateCriteria<FooBar>() .Add(Restrictions.IsNotEmpty("Bazs")).List<FooBar>(); ...assuming there is a collection property (one-to-many) "Bazs" in the FooBar object. Alternatively you could use detached criteria like that: DetachedCriteria dCriteria = DetachedCriteria.For<Baz>("baz") .SetProjection(Projections.Property("baz.FooBarId")) .Add(Restrictions.EqProperty("baz.FooBarId", "fooBar.Id")); var

My Question is exactly like Grails Projections not returning all properties and not grouped I have a following criteria def sharedDocumentsInstanceList SharedDocuments.createCriteria().list(params){ createAlias('receiver', 'r') createAlias('author', 'a') eq("r.id",session.uid) projections{ groupProperty("a.id") property("a.firstName","firstName") property("a.lastName","lastName") property("a.emailAddress","email") } } Where sharedDocuments is defined as follows class SharedDocuments { Users author Users receiver Documents file } What I have seen is that sharedDocumentsInstanceList always has

I have a domain object (Cat) like this: class Cat { String name static hasMany = [ nicknames: String ] } (A cat has a name, and also has many nicknames (which are Strings)) And I am trying to query all the cats with certain nicknames. I've tried this: PagedResultList getCatsByNickname(String nickname, Map params) { PagedResultList results = Cat.createCriteria().list(params) { 'ilike'('nicknames','%'+nickname+'%') } return results } But it never returns any results. (If I change the query to just use the simple name attribute, it works finding all cats with that name, but I want to query

It seems that in Grails 2.x, if you have a domain class association, and you try to run a createCriteria using or on that relation + another query, the or will ignore the other query and just use the results of the nested association. I realize this may be a little confusing, so here is an example: class Passenger { Long id Boolean isDriving } class Car { Long id Passenger passenger Boolean isMoving static constraints = { passenger nullable: true } } and a test: class CarIntegrationTests { @Test void testCar() { Passenger passenger1 = new Passenger(isDriving: true) passenger1.save() Car car1 =
