I am using queryDSL to fetch the inner collection of data and failed to do so. My entities are

}
and in querydsl i am trying below query and always failing to retrieve inner collection towns
List<Expression> childGroup = new ArrayList<>();
query.from(countries);
childGroup.addAll(Arrays.asList(countries.name, countries.data, countries.stateJoin));
query.join(countries.stateJoin, State);
childGroup.add(Projections.bean(State.class, name, count, town)
.as((Path) countries.stateJoin));
OR
childGroup.add(Projections.bean(State.class, name, count, list(town)).as((Path) countries.stateJoin));
query.select(fields);
query.where();
final Map<? extends Number, ? extends Object> t =
(Map<? extends Number, ? extends Object>)
query
.limit(pageRequest.getPageSize())
.offset(pageRequest.getOffset())
.distinct()
.transform(
GroupBy.groupBy(groupByPath)
.as(Projections.bean(Countris.class, childGroup.toArray(new Expression[0]))));
while executing the above line exactly i am getting always SQLSyntax error as i see the underlying SQL is with
. as towns
Can some one help me how to read the nested collection formed by JPA join?
I'm setting an API endpoint that updates an existing user detail, to do that I try to fetch an existing user from the database by id, when I start the application and test with postman it runs the query on my console but displays TransientPropertyValueException: object references an unsaved transient instance - save the transient instance before flushing and fails to make the intended updates.

when I am running eclipse in debug mode then my breakpoint is stuck in delete method. I am using
PostgreSQL 9.6.24 on x86_64-pc-linux-gnu, compiled by Debian clang version 12.0.1, 64-bit
version, and for pool connection Hikari-CP-3.2.0.
And If I let my debug running after long time (~45min) I am getting below error.
marked as broken because of SQLSTATE(08006), ErrorCode(0)\norg.postgresql.util.PSQLException: An I/O error occurred while sending to the backend.
Thanks in advance.
There are two possible reasons for this.
Either your delete statement actually takes a really long time, or it is stuck on a lock.
45 min, is certainly a lot for simple delete and could only be expected when you are working on huge amounts of data, like many millions of rows. Use the explain plan to validate that the expected indexes are used.
I consider locks the more likely reason for the problem. You'll need to check what locks are present and where they are coming from. This wiki page about lock monitoring in PostgreSQL seems to be a good starting point.
When i save the job entity i was expecting that the child under job should also reflect in the db. The problem is that the ref_id and revision does not contain any value from the db.
here is the result from mysql db (removed confidential data)
This is my Job entity class
#Entity
#Table(name = "job")
public class Job implements Serializable {
private static final long serialVersionUID = -2075866246194059832L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "id")
private long id;
#Column(name = "ref_id")
private String refId;
#Column(name = "revision")
private int revision;
#Column(name = "appname")
private String appName;
#Column(name = "vendor")
private String vendor;
#Column(name = "version")
private String version;
#Column(name = "locale")
private String locale;
#Column(name = "platform")
private String platform;
#Column(name = "tier")
private String tier;
#Column(name = "category")
private String category;
#Column(name = "functional_tag")
private String functional;
#Column(name = "job_start_date")
private Date jobStartDate;
#Column(name = "author")
private String author;
#Enumerated(EnumType.STRING)
private Status status;
#Column(name = "release_version")
private String releaseVersion;
#OneToMany(mappedBy = "job", cascade = CascadeType.PERSIST)
private List<Task> tasks;
}
And here is the child
#Entity
#Table(name = "task")
public class Task implements Serializable {
private static final long serialVersionUID = -7395753611385528546L;
#Id
#Column(name = "id")
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
#Column(name = "module_name")
private String moduleName;
#Column(name = "start_time")
private Date startTime;
#Column(name = "end_time")
private Date endTime;
#Enumerated(EnumType.STRING)
private Status status;
#Column(name = "machine_ip")
private String machineIp;
#Column(name = "data_center")
private String dataCenter;
#Column(name = "description")
private String description;
#ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.PERSIST)
#JoinColumns({#JoinColumn(name = "ref_id", referencedColumnName = "ref_id"),
#JoinColumn(name = "revision", referencedColumnName = "revision")})
private Job job;
}
Here is the code that persist the entity
#Service
public class QReaderService {
#Autowired
private JobRepository jobRepository;
#Autowired
private TaskRepository taskRepository;
public boolean addJob(Job job) {
Job previousJob = jobRepository.findByJobRefId(job.getRefId());
if (previousJob == null) {
**jobRepository.save(job);**
return true;
} else {
switch (job.getStatus()) {
case FAILED:
case EXCEPTION:
int revision = 0;
revision += previousJob.getRevision();
previousJob.setStatus(Status.FAILED);
jobRepository.save(previousJob);
break;
}
}
return true;
}
}
This is how i build the job entity
Job job = new Job();
job.setRefId("f78d9as7f98dsa7f97a97f98sda9f7");
job.setAppName("appname");
job.setLocale("locale");
job.setPlatform("platform");
job.setCategory("category");
job.setReleaseVersion("1.1");
job.setStatus(Status.PROCESSING);
job.setAuthor("author");
job.setFunctional("functional");
job.setJobStartDate(new Date());
job.setVersion("1.1");
job.setTier("tier1");
job.setVendor("vendor");
Task task = new Task();
task.setDescription("description");
task.setDataCenter("dataCenter");
task.setStartTime(new Date());
task.setStatus(Status.PROCESSING);
task.setMachineIp("ip");
task.setModuleName("module");
job.setTasks(new ArrayList<Task>(Arrays.asList(task)));
jobRepository.save(job);
To persist child entities when you call save on parent entity, both sides of the relations should be set.
job.setTasks(job.setTasks(new ArrayList<Task>(Arrays.asList(task)));
//Missing line //Important for persistence of child
task.setJob(job);
Hope this helps.
