This Is my coding for mapping data and filter it by subs class:
Hi i have a problem where is my list is null after it mapping the data so can you help me for this solution
void onUserJobListData(Event e) {
Map data = Map.from(e.snapshot.value);
data?.forEach((a, b) {
print("key " + a);
// int i = _jobs.indexWhere((j) => j.jobId == a);
int i = _jobs == null ? 0 : _jobs.indexWhere((j) => j.jobId == a);
if (i >= 0) {
if (b['notification_date'] != null) {
_jobs[i].matchDetail.notificationDate = b['notification_date'];
}
if (b['status_date'] != null) {
_jobs[i].matchDetail.statusDate = b['status_date'];
}
if (b['event_status'] != null) {
_jobs[i].matchDetail.eventStatus = b['event_status'];
}
if (b['notification_status'] != null) {
_jobs[i].matchDetail.notificationStatus = b['notification_status'];
}
if (b['status'] != null) {
_jobs[i].matchDetail.status = b['status'];
}
}
});
print("Apa apa jerr");
jobState.setJobList(_jobs, JobState.USER_JOB);
}`

I have recently added the following code above method:
i.Measure_ID == && i.Measure_ID== (Measureid == 0 ? i.Measure_ID : Measureid)
When adding the highlighted code to this method I am getting following error:

I have tried lot of ways but not working. So, Can anyone help me?
i got stuck on this query that calculate the new column.
i cannot explain briefly just see the snippet code below.
from user in context.Table
select new
{
Total = user.Total,
Paid = user.Paid,
Balance = //should be Total - Paid to assign result
}
i have tried this query
var result = from a in context.EnrollmentRequests
where a.SchoolYear == SchoolYear
select new
{
a.StudentID,
Name = a.Student.FirstName + " " + a.Student.MiddleName + " " + a.Student.LastName,
Tuition = context.Miscs.Where(m => m.YearLevel == a.YearLevel && m.SchoolYear == SchoolYear && m.Term == a.Term && m.CourseID == a.CourseID)
.Select(ms => new { Amount = ms.Amount })
.Union(context.StudentCharges
.Where(s => s.YearLevel == a.YearLevel && s.SchoolYear == SchoolYear && s.Term == a.Term && s.CourseID == a.CourseID && s.StudentID == a.StudentID)
.Select(ss => new { Amount = ss.Amount }))
.Union(context.StudentSubjectTakes
.Where(st => st.StudentID == a.StudentID && st.SchoolYear == a.SchoolYear && st.Term == a.Term && st.YearLevel == a.YearLevel && st.EducationalLevel == a.Student.StudentAdvanceEducations.FirstOrDefault().EducationLevel)
.Select(st => new
{
Amount = context.SubjectOfferedFees
.Where(f => f.SubjectsOfferedID == st.SubjectsOfferedID).Sum(w => (decimal?)w.Cost ?? 0)
}))
.Select(f => f.Amount).Sum(),
PaymentMade = context.Payments.Where(p => p.SchoolYear == SchoolYear && p.Term == a.Term && p.StudentID == a.StudentID && p.PaymentDes == "Tuition Fee").Sum(sm => (decimal?)sm.Amount),
Balance = Tuition - PaymentMade //Does not exist on current context
};
but doesn't work it says that does not exist on current context.
how could this possible.
thanks. this will be helpful to anyone.
Balance = user.Total - user.Paid
I'm new to JPA with the CriteriaBuilder and want to reduce some lines of code.
cb.and is usefull to add predicate's, but what if they are null?
How can I reduce these lines of code? Thanks!
I'm worried about the readability of the code...
CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery cq = cb.createQuery(OrganizationEntity.class);
Root<OrganizationEntity> root = cq.from(OrganizationEntity.class);
Predicate predicateFrom = null;
Predicate predicateTo = null;
if (from != null) {
predicateFrom = cb.ge(root.get(OrganizationEntity_.id), from);
}
if (to != null) {
predicateTo = cb.le(root.get(OrganizationEntity_.id), to);
}
if(predicateFrom != null && predicateTo != null) {
cq.where(cb.and(predicateFrom,predicateTo));
} else if (predicateFrom != null && predicateTo == null) {
cq.where(predicateFrom);
} else if (predicateFrom == null && predicateTo != null) {
cq.where(predicateTo);
}
TypedQuery<OrganizationEntity> query = em.createQuery(cq);
list = query.getResultList();
return list;
what you could do is create your predicate list
List<Predicate> predicates = new ArrayList<>();
if (from != null) {
predicates .add(cb.ge(root.get(OrganizationEntity_.id), from));
}
if (to != null) {
predicates .add(cb.le(root.get(OrganizationEntity_.id), to));
}
if (predicates.size()>0{
cq.where(cb.and(predicates.toArray(new Predicate[predicates
.size()])));
}
First, I would like to know if this query is Lazy loading or Eager loading. I Read a lot on both, and not sure if I understand the difference between each other.
2- I Get this query, This query take a lot of time to execute. Anybody have some suggest when you see this query. I'll do all modification needed to speed up this query.
Note: I just want your opinion about this query and method.
Thanks a lot.

Lazy loading is deferring initialization of an object until the point at which it is needed. If you returned your ListLocation back to its caller, as you've written above, with no .ToList() (or other), then you'd be consuming this lazily.
Eager loading is having the results of your query gathered at the time that the query is defined. In this case it'd be retrieving the results of your LINQ query all at once (at the time that the query is constrcuted). Usually a .ToList() or .Single() or other will do this for you.
I suspect you're consuming the results your LINQ query (var ListLocation) later in your code. Your code above is using a lazy-loaded approach.
You're showing that you're calling .ToList(), so you're indeed using eager-loading; even though it's on a different statement/line of code.
Performance: I'm not 100% on this being your perf problem, but I'd refactor your LINQ into something like this, using an extension method .WhereIf(). It's a heck of a lot easier to read and write.
var ListLocation = from s in _db.Locations
.Where(p => p.IsDelete == false)
.WhereIf(IsActive >= 0, p=> IsActive == (p.IsActive == true ? 1 : 0))
.WhereIf(LocationTypeID >= 0, p=> LocationTypeID == p.LocationTypeID
.WhereIf(City!=null, p=> p.Address.City.CityName.Contains(City)) //etc
If you're using this, and it works, then you're probably lazy loading, since you don't have any calls to .Include().
