I want to query openbravo to filter clients with their phone number. I have two tables BusinessPartner and BusinessPartnerLocation. BusinessPartnerLocation has phone field and businessPartner field that is the id of BusinessPartner object.
I tried like this http://server.opentix.es:3013/openbravo/org.openbravo.service.json.jsonrest/BusinessPartner?_where=e%20IN%20(%20SELECT%20DISTINCT%20bp%20FROM%20BusinessPartner%20RIGHT%20JOIN%20BusinessPartnerLocation%20ON%20BusinessPartner.id=BusinessPartnerLocation.businessPartner%20WHERE%20BusinessPartnerLocation.phone='5555555')
without %20 s or without e In () still it didn't work. How can I build query for this. Thanks
you should use below code that help to get both location geographical and businesspartner location without write hql.
bPartner = OBDao.getOBObjectListFromString(BusinessPartner.class,
strcBpartnerId);
List<Location> ls = bPartner.getBusinessPartnerLocationList();
if (!ls.isEmpty()) {
org.openbravo.model.common.businesspartner.Location Location lcbpartner = ls.get(0);
org.openbravo.model.common.geography.Location lcgeo = lcbpartner.getLocationAddress();
org.openbravo.model.common.businesspartner.Location lcbp = lcbpartner;
}

I have currently a query with a bunch of filters, which makes sense to use the Criteria API, unfortunately I have this query that uses a Join which uses a string value instead of a relationship. This is an example of the query:
SELECT ua.id,
COALESCE(uf.status, f.status) AS status,
r.name,
ua.companyname,
ua.firstname,
ua.lastname,
ua.usergroup,
ua.email,
ua.country,
ua.continent
FROM useraccount ua
JOIN userrole ur on ua.id = ur.userid
JOIN role r on ur.roleid = r.id and r.eventgroupid = 1
JOIN feature f on f.name = 'Locked'
LEFT JOIN userfeature uf on uf.featureid = f.id AND uf.userid = ua.id;
As you can see the problem of the query is that I want to use COALESCE operation to get a UserFeature status if present, if not use the default status from the Feature table.
The feature table is just a simple one with id, name and the status, it is only related to UserFeature and UserFeature at the same time is related to the UserAccount.
As you might guess the CriteriaAPi doesn't allows a Join<> by a regular string value. I have tried to get my mind around to get how can I change the select statement to be more aligned with what CriteriaAPI offers, but I haven't found anything on this.
I'm using PostgreSQL and Hibernate 5.4.32 (by using the spring starter jpa)
Hi I am using a Jqwidgets Grid to display my data. It has a build in possibility to use filters but if you filter your records on the server side you have to build your own query. As I am working with Linq I thought to use the Dynamic Linq Library for Asp net core. Problem is there are not many examples or explanations how to do this. But I am busy for days now and not getting very far.The way I am setup; I have a normal Linq query:
var Mut = from M in _DB.Mutations
join S in _DB.Shifts on M.ShiftId equals S.ShiftId
join U in _DB.RoosterUsers on M.UserId equals U.RoosterUserId
join D in deps on M.UserId equals D.UserId
join DD in _DB.Departements on D.DepartementID equals DD.DepartementId
select new MutationModel
{
MutId=M.MutationId,
Naam=U.FirstName + " " + U.LastName,
UserId=M.UserId,
Departement= DD.DepartementName,
MutationType = S.publicName,
MutationGroup = S.ShiftType.ToString(),
DateTot =M.DateTill,
TijdVan=M.DateStartOn,
TijdTot=M.DateTill,
Status=CreateStatus(M.Tentative, M.ApprovedOn, M.Processed, M.CancelRefId, M.Deleted)
};
This query is running OK and gives me all the data I need for the Grid.
Then for the filter I would like to add a dynamic Linq Query using the System.Linq.Dynamic.Core library
But this is as far as I get things working until now:
var outQuery = Mut.Where("Status = #0 and UserId = #1", "Nieuw", "KLM22940").Select("Status");
My questions now :
1. In the where clause If I make the fieldname variable I get an error. how to do this??
2. In the Select Clause, how to add multiple Columns? (actually I just like to output all columns.)
Best would be to see an example. has somebody used Dynamic Linq to build a dynamic linq query for the JQWidgets Grid?
Thank you very much.
In what way you are trying to use fieldname variable in where clause ?
If you want to output all columns you can use ToList()
like
var outQuery = Mut.Where("Status = #0 and UserId = #1", "Nieuw", "KLM22940").ToList();
If you want to get some specific columns you can use Select clause like this
var outQuery = Mut.Where("Status = #0 and UserId = #1", "Nieuw", "KLM22940").Select("new(Status,UserId )");
This Select clause creates data class which contains Status and UserId properties and returns a sequence of instances of that data class.
I am really poor at LINQ and can't figure out a simple problem. I have a MVC Web API that has a controller. I have a method inside the controller to return back data for comments entered by user for an item.
The data structure is simple - Comments and User tables with UserID column acting as the foreign key
To solve the problem, I have the following method, which has a LINQ query to do a join between Comments and User tables and return back an object in a new extended object that combines the Comments and User details. I cant seem to grab data from the User table. Can someone please help?
public IQueryable<CommentsWithUserDetails> GetReviewsWithUserByItem(int ID)
{
var query = from x in db.Comments
join y in db.Users on x.CommentsUserID equals y.UserID into z
where x.CommentsItemID.Equals(ID)
select new CommentsWithUserDetails
{
CommentsUserID = x.CommentsUserID,
CommentsText = x.CommentsText,
CommentsRating = x.CommentsRating,
CommentsDate = x.CommentsDate,
UserFirstName = y.FirstName,
UserLastName = y.LastName,
UserPictureURL = y.PictureURL
};
return query;
}
The solution is just to remove the 'into z' part from the query, yes as simple as that!

I'm using a LINQ to CRM from Advanced Developer Extension for MS CRM 4.0. It works fine with direct queries. But I've got a problem when query looks like this:
var connectionString = #"User ID=u; Password=p; Authentication Type=AD; Server=http://crm:5555/UO";
var connection = CrmConnection.Parse(connectionString);
var dataContext = new CrmDataContext(connection);
var data = from u in dataContext.Accounts
select new
{
Id = u.AccountID,
Name = u.AccountName,
};
var r = from n in data
where n.Name.StartsWith("test")
select new
{
Id = n.Id
};
r.Dump();
it throws an InvalidOperationException "Cannot determine the attribute name."
It's fine when a condition is directly in first query:
var data = from n in dataContext.Accounts
where n.AccountName.StartsWith("test")
select new
{
Id = n.AccountID,
Name = n.AccountName,
};
I cannot find any useful information about this kind of error. Is it a bug in Xrm Linq Provider?
Thanks in advance for any help.
Try eager loading the initial query with a ToList() so the latter query over your anonymous type is then evaluated locally. I get this is far from ideal if you have a lot of accounts but it'll prove the point. You essentially have a solution anyway in the last statement.
This is because the first query isn't executed at all until you call .Dump() at which point the entire expression including the second query is evaluated as one (deferred execution) by the provider which then looks for an attribute of Name.
I have the version 3.0.0.1001 nhibernate.
My objects are basically modeiling a lineup at an event. So I have a StageSet object which represents one slot in the schedule for a stage.
Each StageSet object has a Stage and an Act property.
It also has many Users - people who have favorited the set.
I'm trying to ascertain the most popular sets that have been favorited using the following linq:
var topStars = from s in Db.StageSets
group s by s.Act.Id into g
select new { SetKey = g.Key, Count = g.Count() };
However this just fails with a Could not execute query[SQL: SQL not available] error
Should I be able to do this?
w://
in case someone comes here. The following should work with NH 3.1
var topStars = from s in Db.StageSets
group s by s.Act.Id into g
select new { SetKey = g.First().Act.Id, Count = g.Count() }
You've specified the query correctly in linq. NHibernate is refusing to translate it.
I just copied your query with a slightly different domain and it worked. But that will count StageSets by Act, NOT favorites.
