criteria

My application creates a dynamically generated query at runtime based on user input by creating Criterion objects e.g: ICriterion criterion = Restrictions.Eq("Name", "John"); ...... detachedCriteriaSomewhereElse.Add(criterion); How do I do this in NHLambdaExtensions? what I really need to do is ICriterion criterion = Restrictions.Eq<Person>(p=> p.Name == "John"); but this isn't valid. Is there any way to do this? With the NHLambdaExtensions you have the SQLExpression class that lets you do the following: ICriterion criterion = SqlExpression.CriterionFor<Person>(p => p.Name == "John"); 来源：

I have two entities in a @ManyToMany relationship. // Output has 4 other @ManyToOne relationships if that matters @Entity @Table public class Output { @Id public String address; @ManyToMany(targetEntity = Interval.class, cascade = CascadeType.ALL, fetch = FetchType.LAZY) @JoinTable(name = "output_has_interval", joinColumns = {@JoinColumn(name = "output_address", referencedColumnName = "address")}, inverseJoinColumns = {@JoinColumn(name = "interval_start", referencedColumnName = "start"), @JoinColumn(name = "interval_end", referencedColumnName = "end")}) Collection<Interval> intervals; @IdClass

I'm trying to set up a quick and dirty GPS lookup via LocationManager which fetches a network location (within 500 meters) every half second for ten seconds. In other words, I'm just trying to find the correct coarse Criteria settings and the correct logic to stop checking after 10 seconds of no better locations within my Handler thread. I'm thinking my main loop should look something like this: /** * Iteration step time. */ private static final int ITERATION_TIMEOUT_STEP = 500; //half-sec intervals public void run(){ boolean stop = false; counts++; if(DEBUG){ Log.d(TAG, "counts=" + counts); }

I'm trying to get my query to only return null records if a radio box on a form is ticked. If I manually include the criteria Is Null in the query it works just fine, and elsewhere things like IIf([Forms]![Reports]![Status - Active]=True,"Active") work just fine. However, IIf([Forms]![Reports]![Status - Null]=True,"Is Null") just ignores it (I assume because it's actually looking for the text "Is Null" rather than null records) and IIf([Forms]![Reports]![Status - Null]=True,Is Null) fails because it's too complex. Is there any way of achieving what I'm trying to achieve? Thanks. You could work

There are two tables in MySQL database user_table feedback The relationship between them is intuitive - one to many from user_table to feedback . I need to fetch only a list of selected columns from these tables which are From feedback feedbackId (java.lang.Long) feedbackTitle (java.lang.String) feedbackDescription (String, decorated by @Lob ) feedbackDate (org.joda.time.DateTime) testimonial (java.lang.Boolean) From user_table userId (java.lang.Long) firstName (java.lang.String) These many fields out of many others are required to get by executing a query. The criteria query is as follows.

I would like to use a hibernate criteria object as a subquery on a second criteria, like this: DetachedCriteria latestStatusSubquery = DetachedCriteria.forClass(BatchStatus.class); latestStatusSubquery.setProjection(Projections.projectionList() .add( Projections.max("created"), "latestStatusDate") .add( Projections.groupProperty("batch.id")) ); DetachedCriteria batchCriteria = DetachedCriteria.forClass(BatchStatus.class).createAlias("batch", "batch"); batch.add( Property.forName( "created" ).eq( latestStatusSubquery ) ); The problem is that adding a groupProperty automatically add that
