I've an existing piece of code like follow:
Criteria crit = session.createCriteria(myClass);
crit.createAlias(TAB1, TAB1, JoinType.LEFT_OUTER_JOIN);
crit.createAlias(TAB1 + ".table2", TAB2, JoinType.LEFT_OUTER_JOIN);
crit.add(Restrictions.eq(TAB1 + ".deleted", Boolean.FALSE));
crit.add(Restrictions.eq(TAB2 + ".id", someId));
This "generates" a sql query like follow:
SELECT * FROM myClass this_
LEFT OUTER JOIN TAB1 tab1_ ON this_.id=tab1_.myClass_id
LEFT OUTER JOIN TAB2 tab2_ ON tab1_.tab2_id=tab2_.id
WHERE tab1_.deleted=0
AND tab2_.id = 1234
I need to put filters in the JOIN condition rather than in the WHERE clause.
To be clear, I need to have the following query:
SELECT * FROM myClass this_
LEFT OUTER JOIN TAB1 tab1_ ON this_.id=tab1_.myClass_id AND tab1_.deleted=0
LEFT OUTER JOIN TAB2 tab2_ ON tab1_.tab2_id=tab2_.id AND AND tab2_.id = 1234
How can I do this?
Thanks
You are using:
crit.createAlias(${table}, ${alias}, ${joinType});
You should be able to use:
crit.createAlias(${table}, ${alias}, ${joinType}, ${Criterion});
Although I could not find an example in our codebase, I would expect this to work.
Here is a decent example right from Hibernates confluence page:
public class PersonDao extends HibernateDaoSupport {
public List<Person> findByName() {
Criteria criteria = getSession().createCriteria(Person.class, "p");
criteria.createCriteria("p.names", "names", JoinType.INNER_JOIN, Restrictions.eq("name", "John"));
return criteria.list();
}
}
Produces
select this_.id as y0_ from person this_
inner join debtor_info this_1_ on this_.id=this_1_.id
left outer join person_person_name personname3_ on this_.id=personname3_.person_id and ( name1_.name=? )
left outer join person_name name1_ on personname3_.person_name_id=name1_.id and ( name1_.name=? )
With that example I believe your code should look something like
Criteria crit = session.createCriteria(MyClass.class, "mine");
crit.createAlias("mine.names", "name", JoinType.LEFT_OUTER_JOIN, Restrictions.eq("name", Boolean.FALSE));
crit.createAlias("q.id", "id", JoinType.LEFT_OUTER_JOIN, Restrictions.eq("id", someId));

Here's my Repository method that I'm trying to call.
#Query(value = "select ise from InquirySession ise " +
"inner join ise.inquiryRequest.inquiryRequestFacilities irf " +
"left outer join ise.inquiryResponses ire on ire.facilityId = ?2 " +
"left outer join ire.responseActions ira " +
"left outer join ire.acceptDates irad " +
"left outer join ire.responseReasons irr " +
"where ise.carePathItem.id = ?1 and irf.facilityId = ?2")
Set<InquirySession> getAllByCarePathItemIdAndProviderId(final Long carePathItemId, final Long providerId);
My thought process was that when this method is executed, ise.inquiryResponses would be joined to InquirySession using the additional 'on' clause defined in the JPQL. However, I think this JPQL only selects InquirySession and does separate calls to join all other entities (defined in InquirySession) as I see separate sql statements after this one joining each entity using the primary/foreign key relationship.
Here's how InquiryResponse looks inside InquirySession
#OneToMany(mappedBy = "inquirySessionId")
#OrderBy(value = "createDate")
private Set<InquiryResponse> inquiryResponses;
and vice versa,
#Column(name = "inquirySessionDatabaseKey")
private Long inquirySessionId;
Is it possible to join InquiryResponse with the additional on clause ire.facilityId = ?2 when hydrating InquirySession entity using JPQL?
Edit
JPQL equivalent SQL
select inquiryses0_.inquirySessionId as inquirySessionId1_36_, inquiryses0_.carepathitemid as CarePat12_36_, inquiryses0_.createDate as createDa2_36_, inquiryses0_.description as descript3_36_,

SQL that does not honor the 'on' clause and joins just on InquirySession.inquirySessionId
select inquiryres0_.inquirySessionId as inquirySessionId5_30_0_, inquiryres0_.inquiryresponseid as inquiryresponseid1_30_0_, inquiryres0_.inquiryresponseid as inquiryresponseid1_30_1_, inquiryres0_.createDate as createDa2_30_1_,

inquiryres0_1_.inquiryresponseactionid as RSPNS_AC1_32_1_, inquiryres1_.inquiryresponseactionid as RSPNS_AC1_34_2_, inquiryres1_.inquiryresponseactiondescription as RSPNS_AC2_34_2_
from InquiryResponse inquiryres0_
left outer join InquiryResponse_Action_Link inquiryres0_1_ on inquiryres0_.inquiryresponseid=inquiryres0_1_.inquiryresponseid
inner join InquiryResponseActions inquiryres1_ on inquiryres0_1_.inquiryresponseactionid=inquiryres1_.inquiryresponseactionid
where inquiryres0_.inquirySessionId=? order by inquiryres0_.createDate
Looking at the first SQL, it's quite evident that the JPQL does not really care about joining other entities in InquirySession as all of the select statements are for InquirySession table. It does a separate SELECT statement to join InquiryResponse and thus, no longer has the expected additional ON clause.

Hibernate is generating a number with table name,
1_, 2_ , 3_
even though while creating SQL this order is not maintained,
it is not even created in the order we give.
Since you haven't posted your mapping file, I'll explain how Hibernate orders the joins.
Hibernate uses the mapping xml file to figure out the order of joins, so if you have a relation in it (one-to-many or any other tag) for that table, just move it above the other table's tag.
You can read more about it here.
I hava query:
Hibernate: select this_.pName as y0_, this_.kNum as y1_, count(*) as y2_ from ALL_CPView this_ inner join ALL_AMView aID1_ on this_.agentid=aID1_.AgentID
and criteria,
Criteria crit = statelessSession.createCriteria(APRecord.class, "apr")
.createAlias("manageID", "ID", Criteria.INNER_JOIN);
crit.setProjection(Projections.projectionList()
.add(Projections.groupProperty("PName"), "PName")
.add(Projections.groupProperty("kNum"), "kNum")
.add(Projections.rowCount() , "count"));
results = crit.setResultTransformer(Transformers.aliasToBean(APStat.class)).list();
How can I add another projection with distinct count for aID with the inner join?
How can I solve this query with Hibernate's detached criteria? The hardest part for me is to bring the and u1.abrechnungsDatum is null into the subselect.
I want a query like this:
select *
from
patient as p
where
p.krankenstand = ?
and
? < ( select count(*) from ueberweisung u1 where p.id = u1.patient_id
and u1.abrechnungsDatum is null)
I have tried it with this
DetachedCriteria dc = DetachedCriteria.forClass(Patient.class, "patient");
dc.add(Restrictions.eq("krankenstand", true));
DetachedCriteria nab = dc.createCriteria("ueberweisungs", "nab");
nab.add(Restrictions.isNull("nab.abrechnungsDatum"));
dc.add(Restrictions.sizeGt("ueberweisungs", 0));
which gives me the following SQL-Statement
select
*
from
patient this_
inner join
ueberweisung nab1_
on this_.id=nab1_.patient_id
where
this_.krankenstand=?
and nab1_.abrechnungsDatum is null
and ? < (
select
count(*)
from
ueberweisung
where
this_.id=patient_id
)
As you can see, the and-clause for the field abrechnungsDatum is not inside the subselect. How can I achieve to get this inside?
Try this instead:
DetachedCriteria dc = DetachedCriteria.forClass(Patient.class, "patient");
dc.add(Restrictions.eq("krankenstand", true));
DetachedCriteria subquery = DetachedCriteria.forClass(Ueberweisung.class);
subquery.add(Restrictions.isNull("abrechnungsDatum"));
dc.add(Subqueries.ltAll(0, subquery));
I am trying to create a Criteria from HQL.
Simplified HQL:
SELECT
event.pkid,
add.name
FROM Event event
LEFT JOIN event.addresses adds
JOIN adds.address add
WHERE adds is null
or adds.addressType = 'EVENT'
And I use following Criteria to produce an equivalent query.
criteria.createAlias("addresses", "adds",
CriteriaSpecification.LEFT_JOIN)
.createAlias("adds.address", "add",
CriteriaSpecification.LEFT_JOIN)
.setProjection(
Projections
.projectionList()
.add(Projections.property("pkid"))
.add(Projections
.property("add.name")))
.add(Restrictions.or(Restrictions.isNull("addresses"),
Restrictions.eq(
"adds.addressType.addressType",
"EVENT")));
But it produces following query,
select
this_.pkid as y0_,
add2_.name as y1_
from event this_
left outer join event_address_map adds1_ on this_.pkid=adds1_.event_pkid
where (this_.pkid is null or adds1_.address_type=?)
Second join is not added. What am I doing wrong?
Thanks in advance.
