Anyone knows how to write join fetch query with jooq ?
my code :
int oid=5;
Select<?> selectQuery = DSL_CONTEXT.select().from(TABLE_A)
.join(TABLE_B).on(TABLE_A.PID.eq(TABLE_B.ID))
.where(TABLE_A.OID.eq(oid))
.orderBy(UPDATED.asc(), ID.asc())
.seekAfter(val(offsetDateTime), val(id))
.limit(50);
this results in : select * from table_a join table_b type of query. How to make it create a query of following type :
select * from table_a join fetch table b ...
Any help is appreciated.
The closest you can get with jOOQ 3.11 out of the box functionality is using ResultQuery.fetchGroups(). On your query, call:
Map<TableARecord, Result<TableBRecord>> result = select.fetchGroups(TABLE_A, TABLE_B);
I am trying to write a query to fetch list as this query is native sql query, all I need is to transform to spring jpql in which I am failing badly. if there is any link related to this please let me know
I am supposed to get list from this query. as this query is working fine with postgres console but when I even tried this with spring jpa as native query
it is showing results in console but not fetching in service layer [edit:] I mean not calculating any result set.
I am sure I am missing some important/small thing here.
below is the native postgres query
selcet t.id,count(*), count(*) filter (where t.status = 'DONE') from table t where t.id in ([list]) group by t.id
what Im trying is
SELECT t.id, count(t), count(t.id) where staus = 'DONE' from Table t where t.id in ([list]) group by t.id
edit: with constructor based query this is not even working
I am not even sure how to start this query
while being new to this I am not even able to start how to solve this.
Any hint, insight will be useful
SELECT recipe.name,SUM(salesdetails.quantity::integer),recipe.price As Quantity
FROM (salesinfo JOIN salesdetails ON salesinfo.sessionid=salesdetails.salesinfo_sessionid)
JOIN recipe ON salesdetails.recipe_id=recipe.id group by salesdetails.recipe_id,recipe.name,recipe.price
ORDER BY SUM(salesdetails.quantity::integer) DESC;
Can anyone give me the hql query for this?
If you are not acquainted with the HQL and want to use the same query ,then you can do it using the native query feature of the Hibernate like this :
#QUERY(value="SELECT recipe.name, SUM(salesdetails.quantity::
INTEGER),recipe.price AS Quantity
FROM (salesinfo
JOIN salesdetails ON salesinfo.sessionid=salesdetails.salesinfo_sessionid)
JOIN recipe ON salesdetails.recipe_id=recipe.id
GROUP BY salesdetails.recipe_id,recipe.name,recipe.price
ORDER BY SUM(salesdetails.quantity:: INTEGER) DESC", nativeQuery = TRUE)
But I would recommend that you first try to convert the same in into HQL query and then if any issue then you should ask it here instead of directly asking for the converted query. Meanwhile this can help.
I'm trying to recreate the following SQL query in QueryDSL. The following is my SQL query which is currently working as inteded.
SELECT * FROM room x WHERE unit_id = (SELECT unit_id FROM room WHERE unit_id = x.unit_id GROUP BY unit_id HAVING(SUM(sqft) > 0))
I'm trying to write a QueryDSL query that does the same thing but honestly can't come any further than the bottom query.
JPASubQuery subQuery = new JPASubQuery();
subQuery.from(qRoom).groupBy(qRoom.unit).having(qRoom.sqft.sum().goe(0));
JPAQuery unitquery = from(qRoom)
.where(qRoom.building.eq(building)).where(qRoom.unit.eq(subQuery));
return unitquery.list(qRoom);
The above query isn't working and i'm having trouble using subqueries in QueryDSL. What should I add/change to make this query working?
Fixed it.
I just needed to change .where(qRoom.unit.eq(subQuery)); too .where(qRoom.unit.in(subQuery.list(qRuimte.unit)));
I have a native SQL query I would like to express with a JPA2 criteria query.
This query already works, but I haven't been able to get it using just JPA2.
I think mostly because I lack experience on this.
I paste the SQL here, maybe you experts can help me to figure it out:
SELECT * FROM
OWNING_POINTS o1
JOIN
(SELECT conversationId, count(*) as nOfMsg
FROM OWNING_POINTS
GROUP BY conversationId) as o2
ON o1.conversationId = o2.conversationId
LEFT JOIN
(SELECT id, created as newerUnreadMessage
FROM OWNING_POINTS
WHERE `read`=0) as o3
ON o1.id = o3.id " +
WHERE o1.owner_user_id=?
ORDER BY newerUnreadMessage DESC, nOfMsg DESC
Thank you very much.
