Convert SQL Query to Criteria Query in Spring Boot

I'm relatively new to Spring JPA CriteriaQuery. Im trying to convert my old native query in my program to criteria query and haven't been successful on join query for multiple table with conditions. I need help converting native SQL query into Criteria Query for these query below :
select * from student s inner join (
select distinct on (student_id) * from class where status = 'Active' order by
student_id,date_register desc) c on s.id = c.user_id
inner join teacher t on t.subject_id = c.subject_id
where t.status = 'Active' and s.status='Active' order by s.name desc
Update :
Below code is as far as I can go cause I dont really know much. Am i in the right direction? I'm opting for Expression because i dont know how to use Join.
CriteriaQuery<Student> query = cb.createQuery(Student.class);
Root<Student> sRoot= query.from(Student.class);
query.select(sRoot);
Subquery<Integer> subquery = query.subquery(Integer.class);
Root<Class> cRoot= subquery.from(CLass.class);
Expression<Integer> max = cb.max(cRoot.get("dateRegister"));
subquery.select(max);
subquery.groupBy(cRoot.get("student"));
query.where(
cb.and(
cb.in(cRoot.get("dateRegister")).value(subquery)
)
);
Thanks in advance!

Flexible Search Issue SAP Hybris

I have a problem with a Flexible Query. This is my query:
Select
{pp.productCode} as 'Code',
{p.descriptionCics} as 'Desc CISC',
{bs.uid} as 'Store',
{evo.code} as 'Status',
{p.department} as 'Department',
{pca.name} as 'Category',
{p.grm} as 'GRM',
{p.buyerCode} as 'Code Buyer',
{p.buyerids} as 'Buyer',
{ps.planogramCode} as 'Code Planogram',
{pca.categoryCode} as 'Category Planogram',
{s.puvmBlock} as 'Blocked',
(CASE WHEN ({p.productDetailTypeList} is not null )THEN 'YES' else
'NO' END) as 'IMAGE'
from
{
Product as p
JOIN PlanogramProducts as pp on {p.code} = {pp.productCode}
JOIN StockLevel as s on {pp.productCode} = {s.productCode}
JOIN EnumerationValue as evo on {p.status} = {evo.pk}
JOIN PlanogramCategory as pc on {pp.planogramCode} =
{pc.planogramCode}
JOIN PlamnogramCategoryAnag as pca on {pc.categoryCode}=
{pca.categoryCode}
JOIN BaseStore as bs JOIN PlanogramStore as ps on {bs.storeRef} =
{ps.storeRef} AND {bs.bramchOffice} = {ps.branchOffice}
}
WHERE 1=1
and this my error when I execute it:
Can someone help me? Thanks a lot.

Your statement contains errors. You join basestore with planogramStore. But neither planogram store, nor basestore is joined with any other part of your query. You need to join basestore or planogramstore with one of the other tables.
Now you have 2 detached parts in your from statement, which is why you are getting errors
Product as p
JOIN PlanogramProducts as pp on {p.code} = {pp.productCode}
JOIN StockLevel as s on {pp.productCode} = {s.productCode}
JOIN EnumerationValue as evo on {p.status} = {evo.pk}
JOIN PlanogramCategory as pc on {pp.planogramCode} =
{pc.planogramCode}
JOIN PlamnogramCategoryAnag as pca on {pc.categoryCode}=
{pca.categoryCode}
and
JOIN BaseStore as bs JOIN PlanogramStore as ps on {bs.storeRef} =
{ps.storeRef} AND {bs.bramchOffice} = {ps.branchOffice}
you need to have a join between these 2 parts to get the correct data

remove duplicate Data after Execute SelectQuery in mutliple Tables

i have Three tables [users,projects,scenarios] i need to get latest update projects details based on modified Date column with out duplicate values
the tables are:
users Table :
project table
scenario Table
and i try below query but its return duplicates values if am using group by then old values came but i need latest values
With out Group by query
SELECT
p.`PROJECT_NAME`,
p.`CREATED_DATE`,
s.`MODIFIED_DATE`
FROM
`projects` p
JOIN `scenarios` s ON
s.`PROJECT_ID` = p.`PROJECT_ID`
WHERE
P.`USER_ID` =(
SELECT
USER_ID
FROM
users
WHERE
EMAIL = 'test#gmail.com'
)
ORDER BY
s.`MODIFIED_DATE`
DESC
out put:
with Group by Query :
SELECT
p.`PROJECT_NAME`,
p.`CREATED_DATE`,
s.`MODIFIED_DATE`
FROM
`projects` p
JOIN `scenarios` s ON
s.`PROJECT_ID` = p.`PROJECT_ID`
WHERE
P.`USER_ID` =(
SELECT
USER_ID
FROM
users
WHERE
EMAIL = 'test#gmail.com'
)
group by p.PROJECT_NAME
ORDER BY
s.`MODIFIED_DATE`
DESC
output:

You can separately get the latest scenario per project using a subquery then the resulting rows will then be join again to get the other columns, if needed.
SELECT p.PROJECT_NAME,
p.CREATED_DATE,
s.MODIFIED_DATE
-- all columns in s.* will have the latest row
FROM projects p
INNER JOIN scenarios s
ON p.PROJECT_ID = s.PROJECT_ID
INNER JOIN
(
SELECT project_ID, MAX(modified_date) MAX_modified_date
FROM scenarios
GROUP BY project_ID
) t ON s.project_ID = t.project_ID
AND s.modified_date = t.MAX_modified_date
INNER JOIN users u
ON P.USER_ID = u.USER_ID
WHERE u.EMAIL = 'test#gmail.com'
ORDER BY s.MODIFIED_DATE DESC
However, if you don't need to get the other columns, you can directly use MAX() and GROUP BY.
SELECT p.PROJECT_NAME,
p.CREATED_DATE,
MAX(s.MODIFIED_DATE) AS MAX_MODIFIED_DATE
FROM projects p
INNER JOIN scenarios s
ON p.PROJECT_ID = s.PROJECT_ID
INNER JOIN users u
ON P.USER_ID = u.USER_ID
WHERE u.EMAIL = 'test#gmail.com'
GROUP BY p.PROJECT_NAME,
p.CREATED_DATE
ORDER BY MAX_MODIFIED_DATE DESC

How to create mapping of composed object with Hibernate when using a complex sqlquery?

I am trying to use the below query with Hibernate's session.createSQLQuery.
The Entity object corresponding to user has an attribute called address.
The address object is created out of 5 fields from table 'user'.
If I do not use an SQLQuery it gets filled auto-magically.
However without the SQLQuery I can't get all the info I would get from the desired joins shown below.
The user entity object also attributes like accessPlan which I am filling up using
.addEntity("accessPlan", AccessPlan.class)
Query:
SELECT
user.*,
ap.*,
country.*,
auth.*,
GROUP_CONCAT(coup.code SEPARATOR ' ') coupons
FROM
user
INNER JOIN access_plan ap ON (user.access_plan = ap.id)
INNER JOIN country ON (user.country=country.code)
LEFT JOIN user_auth auth ON (user.id = auth.userid)
LEFT JOIN (
SELECT
trans.user_id,coupon.code
FROM
payments_transaction AS trans
INNER JOIN payments_coupon coupon ON (trans.payments_coupon_id=coupon.id)
) coup ON (user.id=coup.user_id)
GROUP BY user.id;
What can be the easiest way to fill up the composed address object while using the SQLQuery?
OR
Is there a way to avoid using SQLQuery for a query like this?

Please check below example from the section 'Returning multiple entities'
String sql = "SELECT ID as {c.id}, NAME as {c.name}, " +
"BIRTHDATE as {c.birthDate}, MOTHER_ID as {c.mother}, {mother.*} " +
"FROM CAT_LOG c, CAT_LOG m WHERE {c.mother} = c.ID";
List loggedCats = sess.createSQLQuery(sql)
.addEntity("cat", Cat.class)
.addEntity("mother", Cat.class).list()
In your case, cat = user, mother = address... somewhat like that.
I do not have anything to try out at the moment but I guess this will help.

Hibernate Query for equivalent sql

Can someone help me in writing equivalent hql for this query
SELECT IFNULL(oea.`organization_name`,'') FROM `consultation_appointment` ca
JOIN `organization_employee_association` oea ON ca.`consultation_id` = oea.id
JOIN professional_profile pp ON oea.`employee_profile_id` = pp.profile_id
I could able to join the first JOIN like this
select ca.name from ConsultationAppointment ca join ca.consultation oea
Because the ConsultationAppointment class having organization_employee_association variable so it easier to join, difficulty is organization_employee_association not having direct mapping to organization_employee_association class.
Even GORM criteria Query is helpful.

HQL does not allow joining two unassociated entity, you should use cartesian product instead.
String query = "SELECT ca.name FROM consultation_appointment ca JOIN organization_employee_association oea, professional_profile pp WHERE oea.employee_profile_id = pp.profile_id";
List<String> caNames = session.createQuery(query).list();
One another possibility is to use the method createSQLQuery(). It provides more flexibility to execute an arbitrary join.
String query = "SELECT ca.name FROM consultation_appointment ca JOIN organization_employee_association oea ON ca.consultation_id = oea.id JOIN professional_profile pp ON oea.employee_profile_id = pp.profile_id";
List<String> caNames = session.createSQLQuery(query).list();
