I am getting erro while executing the query.and No proper error are there in the logs.It only says. Error in query findAllfundSalesCreditCalc.Can anybody help what wrong in it.
#NamedQuery(name="findAllfundSalesCreditCalc",query="select distinct FCM from SubFund SF" +
"join Class C on C.id = SF.id" +
"join SC_Class SCC where SCC.classId = C.id" +
"left join FundSalesCreditCalcMethod FCM where FCM.SubFundId = SF.id")
You're missing whitespaces:
#NamedQuery(name="findAllfundSalesCreditCalc",query=
"select distinct FCM from SubFund SF" +
" join Class C on C.id = SF.id" +
" join SC_Class SCC where SCC.classId = C.id" +
" left join FundSalesCreditCalcMethod FCM where FCM.SubFundId = SF.id")
// ^
// | here
Just because you put a concatenated string on a new line in Java doesn't mean that the (Java) whitespace is reflected in your SQL query.

I am trying to use this query in springboot so I can display the results in a webpage. I know that this query works because I tested it in postgresql and it gave me the right results.
But JPA is telling me that the '(' after the first FROM is an unexpected token and the query was therefore viewed as invalid.
This is my query:
#Query(
"SELECT com.example.imse22.model.TrvlA_Cust_Dto(books_query.name, count(travelA_query.customer_id)) " +
"FROM (SELECT DISTINCT customer_servant.employee_id, books.customer_id FROM customer_servant " +
"INNER JOIN books ON customer_servant.employee_id = books.customer_servant_id) AS travelA_query " +
"INNER JOIN " +
"(SELECT travel_agency.id, travel_agency.name, employee.employee_id FROM travel_agency " +
"INNER JOIN employee ON travel_agency.id = employee.travel_agency_id) AS books_query " +
"ON travelA_query.employee_id = books_query.employee_id " +
"GROUOP BY travelA_query.name")
can somebody help me out how I could rewrite the query so that JPA approves it?
Your query is native so you should declare it in that way:
#Query(
value = "SELECT com.example.imse22.model.TrvlA_Cust_Dto(books_query.name, count(travelA_query.customer_id)) " +
"FROM (SELECT DISTINCT customer_servant.employee_id, books.customer_id FROM customer_servant " +
"INNER JOIN books ON customer_servant.employee_id = books.customer_servant_id) AS travelA_query " +
"INNER JOIN " +
"(SELECT travel_agency.id, travel_agency.name, employee.employee_id FROM travel_agency " +
"INNER JOIN employee ON travel_agency.id = employee.travel_agency_id) AS books_query " +
"ON travelA_query.employee_id = books_query.employee_id " +
"GROUOP BY travelA_query.name", nativeQuery = true)

Ok so this is how I solved it:
I changed my query into a native one just like #notAPPP pointed out and then I only had to add an alias for the LEFT JOIN (also I changed INNER JOIN to LEFT JOIN).
here the code example:
#Query(value = "SELECT combined.name as name, count(combined.customer_id) as id " +
"FROM (" +
"(SELECT travel_agency.name, travel_agency.id, employee.employee_id " +
"FROM travel_agency INNER JOIN employee ON travel_agency.id = employee.travel_agency_id) as trvlEmp " +
"LEFT JOIN " +
"(SELECT books.customer_id, books.customer_servant_id, customer_servant.employee_id " +
"FROM books INNER JOIN customer_servant ON books.customer_servant_id = customer_servant.employee_id) as custBooks " +
"ON trvlEmp.employee_id = custBooks.employee_id) as combined " + // this "AS combined" got added
"GROUP BY combined.name", nativeQuery = true)
This makes sense, because after a FROM clause one should wirte the name of a table or a result table (e.g. from two joined queries like in my case). As I didnt specify an alias for the LEFT JOIN of my two subqueries, JPA obviously didnt know how to handle the result of those subqueries. Therefore always name your subqueries if they are not used in a WHERE clause, but rather with a FROM clause, like in my case. E.g. the name I gave my LEFT JOIN is "combined" as seen in the code example above.
Also I changed my INNER JOIN to a LEFT JOIN to get the value 0 of the elements that have 0 counts of what I wanted to count in the table.

Currently I have such piece of code, which doesn't work, since I have to add schema name before each table in a query(like DEV.DASHBOARDS_METADATA):
public interface DashboardMetadataDao extends CrudRepository<DashboardMetadata, Integer> {
#Query("SELECT D FROM DASHBOARDS_METADATA D " +
"INNER JOIN FAC_DASHBOARDS_LINK DL ON D.ID = DL.DASHBOARD_ID " +
"INNER JOIN FIRMS F ON DL.FAC_ID = F.FAC_UNIT_ID " +
"INNER JOIN USERS U ON U.FIRM_ID = F.FIRM_ID WHERE LOWER(U.USERID) = LOWER(:userid)")
public Set<DashboardMetadata> findByUserId(#Param("userid") String userId);
}
The problem is that schema name differs from database to database (DEV/QA/PROD). Normally I use component's method which prepend schema's name to each table during query generation. How can do this using annotations?
Thanks!
Hibernate has a variable that can be used in native queries to get schema name called: {h-schema}
https://docs.jboss.org/hibernate/orm/5.2/userguide/html_single/chapters/query/native/Native.html#sql-global-catalog-schema You can just put {h-schema}table in your query. I think you have to convert it to a native query.
Below Code Snippet worked for me
#Query(
value = "select *\n" +
"from {h-schema}TABLE-A r left join {h-schema}TABLE-B p on r.ID=p.ID\n" +
"left join {h-schema}TABLE-C pe on p.ID=pe.ID\n" +
"left join {h-schema}TABLE-D e on pe.ENT_ID=e.ENT_ID\n" +
"where r.role_type='Provisioning'",
nativeQuery = true)
I have the following code
#Query(nativeQuery = true, value = "select e.* from event e"
+ " join league l on (l.id = e.league_id)"
+ " join sport s on (l.sport_id = s.id)"
+ " join team t1 on (t1.id = e.team_one_id)"
+ " join team t2 on (t2.id = e.team_two_id)"
+ " join country c on (c.id = l.country_id)"
+ " where l.name LIKE %?1%")
Page<Event> getAllEventsFiltered(final PageRequest of, final String filter);
If execute this SQL into database I receive a lot of results but when is executed from java I receive no one result in the same SQL.
I already tried:
where l.name LIKE %?#{escape([1])} escape ?#{escapeCharacter()}
but just works to begins and I needs for both begin and end.
JDBC parameters can only be included in very specific places in a SQL statement. They are not replaced as strings in the SQL statement but they are applied. The specific valid places change from database to database, and also depend on the JDBC driver variant/version.
The general rule is that a parameter can be applied where a single value would be present. String parameters should not be enclosed in single quotes as a VARCHAR would be.
One option to make it compliant, is to place the parameter isolated from other text, for example by using the CONCAT() function. Your query could be rephrased as:
#Query(nativeQuery = true, value = "select e.* from event e"
+ " join league l on (l.id = e.league_id)"
+ " join sport s on (l.sport_id = s.id)"
+ " join team t1 on (t1.id = e.team_one_id)"
+ " join team t2 on (t2.id = e.team_two_id)"
+ " join country c on (c.id = l.country_id)"
+ " where l.name LIKE concat('%', ?1, '%')") // change here
Nevertheless, the specific syntax change can be different depending on the database you are using (that you haven't mentioned).
I use the following query:
SELECT * FROM phaseinproject as pip JOIN projectinrelease pir
ON pip.projectInRelease_id = pir.id
JOIN releaseperiod as rp ON pir.release_id = rp.id
JOIN releasestructure as rs ON rs.id = rp.releaseStructure_id
JOIN phaseinreleasestructure as pirs ON pirs.releaseStructure_id = rs.id
JOIN releasephase as rlp ON rlp.id = pirs.phase_id
AND rlp.id = pip.phase_id
This query works totally fine. I get three results (the amount I expect).
I convert this query to the following HQL query:
TypedQuery<PhaseInProjectOverview> findPhasesInRelease = em.createQuery("SELECT NEW nl.dashboard.dto.out.PhaseInProjectOverview(phaseInProject.id, phase.name, phaseInProject.startDate, phaseInProject.plannedEndDate, phaseInProject.endDate) FROM PhaseInProject phaseInProject "
+ "JOIN phaseInProject.projectInRelease projectInRelease "
+ "JOIN projectInRelease.release release "
+ "JOIN release.releaseStructure releaseStructure "
+ "JOIN releaseStructure.phaseInReleaseStructures phaseInReleaseStructure "
+ "JOIN phaseInReleaseStructure.phase phase "
+ "WHERE release.id = :releaseId ORDER BY phaseInReleaseStructure.position, phaseInProject.startDate", PhaseInProjectOverview.class);
findPhasesInRelease.setParameter("releaseId", releaseId);
return findPhasesInRelease.getResultList();
No matter what I try: I get 6 results, because HQL does not seem to support the "JOIN ... ON ... AND ..." sql syntax.
Does anyone know how to solve this problem?
edit:
I added my own answer with the used solution. Thank you all for the answers/pointers.
Try the with keyword: phaseInReleaseStructure.phase phase WITH phase.id = phaseInProject.phase_id - this should result in SQL like releasephase as rlp ON rlp.id = pirs.phase_id AND rlp.id = pip.phase_id
Alternatively just add that condition in the where clause:
... WHERE release.id = :releaseId AND phase.id = phaseInProject.phase_id ...
I solved my problem with an extra WHERE clause:
phase.id = phaseInProject.phase.id
Now I get the results I was expecting.
The 'WITH' keyword does not seem to work with multiple entities. When I try, I get an exception:
HQL error: with-clause referenced two different from-clause elements
When trying to use the 'ON' syntax like JOIN phaseInReleaseStructure.phase phase ON phase.id = phaseInProject.id, I get another error:
unexpected token: ON near line 1, column 473
Okay im getting a bit confused atm, im trying to retrieve some data from a datebase using java and mssql.
In sql i write this:
use MyChamp SELECT *
FROM [GROUP]
JOIN Team on [Group].GroupID = Team.GroupID
JOIN Match on Team.TeamID = HomeTeamID
WHERE [GROUP].GroupID = 9
and it work.
In java my string to execute looks like this:
String sql = "SELECT * FROM [GROUP]"
+ "JOIN Team on [Group].GroupID = Team.GroupID"
+ "JOIN Match on Team.TeamID = HomeTeamID"
+ "WHERE [GROUP].GroupID = 9"
+ "ORDER BY MatchRound:";
It does not work i get sql error msg saying:
Error: S0001Incorrect syntax near 'Match'.
but i cant find the error :(
Put spaces after string termination quote "
String sql = "SELECT * FROM [GROUP] "
+ "JOIN Team on [Group].GroupID = Team.GroupID "
+ "JOIN Match on Team.TeamID = HomeTeamID "
+ "WHERE [GROUP].GroupID = 9 "
+ "ORDER BY MatchRound "
If you don't your string will be generated like this.
SELECT * FROM [GROUP]JOIN Team on [Group].GroupID = Team.GroupIDJOIN Match on Team.TeamID = HomeTeamIDWHERE [GROUP].GroupID = 9ORDER BY MatchRound
