Spring JPA Method name for a 2 table query using #Query

EDITTED
Curious... I have a custom Spring JPA query which I'm not sure how to write.
I'm extending PagingAndSortingRepository
The #Query: select * from Table1 tb1 JOIN Table2 tb2 on tb1.id = tb2.tb1_id
where tb2.personId = :personId and tb1.mainId=:mainId and tb2.status in (:statusList)
I'm not sure how to create the method name for this as it keeps giving me an error saying it can't find status in the Table1.
I figured something like:
public Page findByMainIdAndStatusInAndPersonId(#Param("mainId") Integer mainId, ..........); would work but it's telling me it can't find status. Which is understandable since status is in the Table2 object which I'm trying to join on.
**Table1**
id
column1
column2
mainId
List<Table2> table2List
**Table2**
id
table1_id
status
person_id
table 1 and 2 are linked via table2's table_id column. however in the Table1 JPA repository, I need to fetch all of Table1 based on criteria in Table2.
I checked "property expressions" but I'm not catching how to write the jpa method name
Thanks guys :)

After a while of looking around and trying different things... ANSWER:
When you want to query on Table2, you need to add it to the method as:
findBymainIdAndTable2List_StatusInAndTable2List_personId
So essentially add the list name followed by underscore and the column name in that table. If anyone wants to add more, def feel free :D This is how I got it to work

How to execute a JPA Bulk Update statement which takes a List as a parameter value

I have an Update Query that looks like this
UPDATE
table_name
SET
column_name = ?
WHERE
column_name = ? AND id in (?)
So the JPA transaction is
em.createNativeQuery(Update_QUERY)
.setParameter(1, updatedStatus)
.setParameter(2, currentStatus)
.setParameter(3, ids)
.executeUpdate();
The Input to the method is List id, currentStatus, and updatedStatus
How do I pass the List as a single parameter, if I convert the List to a comma-separated String I get the error Specified text is not number as strings is not allowed in the In clause.

How do I pass the List as a single parameter
An example approach:
String jpql = "UPDATE NameEntity ne " +
"SET ne.valstring = :updated_status " +
"WHERE ne.valstring = :current_status AND ne.id IN :ids";
em.createQuery(jqpl)
.setParameter("updated_status", updatedStatus)
.setParameter("current_status", currentstatus)
.setParameter("ids", Arrays.asList(ids))
.executeUpdate();
Three simple rules:
Use native SQL for bulk update / delete on tables that are not mapped to entities.
Native SQL queries work directly on database tables bypassing the persistence context (a set of managed entities), so it is safe to use such queries if a given database table has no corresponding entity.
Use JPQL for bulk update / delete on tables that are mapped to entities
In case of a given database table is mapped by an entity, using a SQL update / delete will lead to inconsistency between persistence context and the underlying database, so use JQPL counterparts instead and the persistence provider will take care of consistency.
Bulk update / delete should be executed as the first operation within the transaction or ideally in its own transaction.

Setting a List parameter
The JPA Query interface setParameter method that accepts an Object parameter:
Query setParameter(String name, Object value)
can take a List as the parameter value.
This works in the same way for JPQL, Criteria API, or bulk update and delete queries:
List<Post> posts = entityManager.createNativeQuery("""
UPDATE
post
SET
status = :newStatus
WHERE
status = :oldStatus AND
id IN :ids
""", Post.class)
.setParameter("oldStatus", PostStatus.PENDING)
.setParameter("newStatus", PostStatus.APPROVED)
.setParameter("ids", List.of(1L, 2L, 3L))
.executeUpdate();

Convert Postgresql query to Hibernate

In my Java Web application I use Postgresql and some data tables are filled automatically in server. In the database I have a STATUS table like below:
I want to select the data related to a vehicle between selected dates and where the vehicle stayed connected. Simply I want to select the data which are green in the above table which means I exactly want the data when firstly io1=true and the data when io1=false after the last io1=true. I have postgresql query statement which exactly gives me the desired data; however, I have to convert it to HQL because of my application logic.
working postgresql query:
WITH cte AS
( SELECT iostatusid, mtstrackid, io1,io2,io3, gpsdate,
(io1 <> LAG(io1) OVER (PARTITION BY mtstrackid
ORDER BY gpsdate)
) AS status_changed
FROM iostatus
WHERE mtstrackid = 'redcar' AND gpsdate between '2014-02-28 00:00:00' and '2014-02-28 23:59:59'
)
SELECT iostatusId, mtstrackid, io1, io2, io3,gpsdate
FROM cte
WHERE status_changed
OR io1 AND status_changed IS NULL
ORDER BY gpsdate ;
How should I convert the above query to HQL or how could I retrieve the desired data with HQL?

The goal of hibernate is mapping database entities to java objects. This kind of complex queries are not entities themselves. This is against the spirit of hibernate.
If this query generates an entity in your application logic, I recommend putting the results into a table and applying Hibernate queries to that table.
If this query generates some kind of aggregation or summary, there are two possible ways:
One way is you compute this aggregation/summary in your application after retrieving entities from iostatus table with hibernate.
If this query has nothing to do with your application logic then you can use Native SQL interface of Hibernate and execute the query directly. (You can even use JPA if you are willing to manipulate two database connections.)
If you absolutely need to convert it to HQL, you need to eliminate the partition function. If the order of iostatusId is identical to the order of gpsdate, you can do it similar to
SELECT i2.*
FROM iostatus i1
INNER JOIN iostatus i2 ON i1.iostatusId = i2.iostatusId - 1
AND i1.io1 <> i2.io1
AND i1.mstrackid = i2.mstrackid
WHERE i2.mtstrackid = 'redcar' AND
i2.gpsdate between '2014-02-28 00:00:00' and '2014-02-28 23:59:59'
If gpsdate is no way related to iostatusId then you need something like
SELECT i2.*
FROM iostatus i1
INNER JOIN iostatus i2 ON i1.gpsdate < i2.gpsdate
AND i1.io1 <> i2.io1
AND i1.mstrackid = i2.mstrackid
WHERE i2.mtstrackid = 'redcar' AND
i2.gpsdate between '2014-02-28 00:00:00' and '2014-02-28 23:59:59' AND
NOT EXISTS (SELECT * FROM iostatus i3
WHERE i3.gpsdate > i1.gpsdate AND
i2.gpsdate > i3.gpsdate AND
i3.io1 = i1.io1 AND
i1.mstrackid = i3.mstrackid)
I guess both of the queries can be converted to HQL, but I'm not positively sure.
By the way I must warn you that, these methods might not perform better then finding the changes in your application, because they involve joining the table onto itself, which is an expensive operation; and the second query involves a nested query after the join, which is also quite expensive.

JPA/Hibernate query construction

I am fetching records from my "record" table. "record" table has many columns tow of which are
client_id, foreign key mapping to client table.
creation_date , date of record creation
I would like to do a query on this table , but I would like to fetch only one record per client(latest creation_date record has preference).
Will following work?
select r.id,r.xx,r.yy
group by(r.client_id),r.creation_date
from record r
order by creation_date desc
I tried above and seems records fetched are not of latest creation dates.
Hope my question is clear

Just keep your query and add a WHERE condition :
SELECT r.id,r.xx,r.yy
GROUP BY(r.client_id)
FROM record r
WHERE r.creation_date = (SELECT MAX(creation_date) FROM record tmp WHERE tmp.client_id = r.client_id )
Take a look at This discussion

This should give you a good starting point in HQL.
from Record as r inner join fetch r.client
where r.creation_date > (
select max(rec.creation_date) from Record rec
where rec.client.client_id = r.client.client_id
)
This of course assumes that your Record has a reference to its parent Client called client.

How to map native query to one model class?

Hi I´m using Eclipselink and I did a native query to select some fields of 2 tables. I mapped my table Logins in a model class. I would not like to map my table "B" because I need only 2 fields of this table on my sql result.. can I map this 2 fields in my Logins table to my sql result ?
My sql is this:
select l.login_id, s.lugarcerto,s.vrum, l.username, l.first_name, l.last_name, l.phone, l.fax_number, l.address, l.zip,
l.address2 as 'birth_date', l.city as 'cpf_cnpj'
from Logins l
join (select se.login_id, lugarcerto = min(case when se.service = 'IM' then '1' end), vrum = min(case when se.service = 'VE' then '1' end)
from (select distinct ad.login_id, substring(ap.Rate_code,(CHARINDEX('-', ap.Rate_code)+1),2) as 'service'
from Ad_Data.dbo.ad ad
join Ad_Data.dbo.ad_pub ap on (ad.ad_id = ap.ad_id)
where ap.ad_type =1) se
group by se.login_id) s on (s.login_id = l.login_id)
I did map Logins table and I want to map s.lugarcerto and s.vrum to my SQL query result.
There´s anyway to just add it to my Logins model ?

Not without having mappings for the attributes you want those values put into, and not without causing problems with them being cached in the entity.
Why not just return the values beside the entity, much like you would with a JPQL query such as: "Select l, subquery1, subquery2 from Logins l" ie:
Query q = em.createNativeQuery(yourQueryString, "resultMappingName");
And in the entity, include the annotation:
#SqlResultSetMapping(name="resultMappingName",
entities={#EntityResult(entityClass=com.acme.Logins.class, )},
columns={#ColumnResult(name="LUGARCERTO"), #ColumnResult(name="VRUM")}
)
