I am stuck at the moment while trying to write the next query as a spring-data JPA query:
with recursive s as (
select *
from t
where file_id = '12345'
union all
select dfs.*
from t dfs
join s on s.file_id = dfs.parent_folder_id
)
select * from s;
I have tried the next:
#Query(value = "with recursive subfiles as (
select * from t where file_id=?1
union all
dfs.* from t dfs join subfiles s
on s.file_id = dfs.parent_folder_id)
select file_id from subfiles", nativeQuery = true)
But I get the next error:
Method threw 'org.springframework.dao.InvalidDataAccessResourceUsageException' exception.
could not extract ResultSet; SQL [n/a]
org.hibernate.exception.SQLGrammarException: could not extract ResultSet
org.postgresql.util.PSQLException: ERROR: syntax error at or near "dfs"
The query should list all direct or indirect dependent children for a specific id. (a similar post here)
I have managed to fix it using the next format:
#Query(nativeQuery = true,
value = "with recursive subfiles as " +
"(select * " +
"from t " +
"where file_id=?1 " +
"union all " +
"select dfs.* " +
"from t dfs " +
"join subfiles s " +
"on s.file_id = dfs.parent_folder_id) " +
"select file_id from subfiles")
List<String> listAllByParentId(String folderId);

I have a native query like the following one:
#Query(value = "SELECT * FROM (" +
" SELECT result.*, ROWNUM rn FROM (" +
" SELECT tmp.* FROM (" +
" SELECT " +
" e.id, " +
" e.employee_number, " +
" d.name, " +
" d.surname " +
" FROM employee e INNER JOIN detail d ON e.id_detail = d.id " +
" WHERE e.status = :status " +
" ) tmp " +
" ORDER BY :sortColumn :sortDirection " +
" ) result " +
" WHERE ROWNUM <= (:pageIndex + :pageSize) " +
") " +
"WHERE rn > :pageIndex "
, nativeQuery = true)
ArrayList<Object> getEmployeeDetails( #Param("status") EmployeeStatus status,
#Param("pageSize") int pageSize,
#Param("pageIndex") int pageIndex,
#Param("sortDirection") String sortDirection,
#Param("sortColumn") String sortColumn);
and I'm getting the following errors:
org.springframework.dao.InvalidDataAccessResourceUsageException: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet
// ...
Caused by: org.hibernate.exception.SQLGrammarException: could not extract ResultSet
// ...
Caused by: java.sql.SQLSyntaxErrorException: ORA-01745: invalid host/bind variable name
What I tried is different return type (and didn't manage to find out which one to use eventually), inserting params with #Param() annotations.
The query itself does work - I tried it directly in the database, but I'm experiencing problems with handling it in Spring.
The query itself for easy debugging:
SELECT * FROM (
SELECT result.*, ROWNUM rn FROM (
SELECT tmp.* FROM (
SELECT
e.id,
e.employee_number,
d.name,
d.surname
FROM employee e INNER JOIN detail d ON e.id_detail = d.id
WHERE e.status = 'status'
) tmp
ORDER BY tmp.name desc
) result
WHERE ROWNUM <= (0 + 5)
)
WHERE rn > 0
EDIT:
I've updated the question with comment suggestions of removing all of the \n's and checking for missing whitespaces.
Plain query, without using any parameters also work, but as I start to insert parameters through #Param() annotations or binds (?1) it stops working giving the errors I updated above.
if EmployeeStatus is enum you have to use this in your query
WHERE e.status = :#{#status.name()}
I am trying to write a query like the below on unrelated entities A and B
Select a.x,a.y,a.z FROM A a ,B b Where
b.Parameter_Name='APPLICABLE_RULE_TYPE' And b.Parameter_KEY='MC' AND
b.Parameter_Value=a.rule_type And a.Rule_Status='ON' Order By Rule_Priority;
I am not able to figure out how this should be written in the Repository class of a Spring boot application.
Can someone please suggest a way do this
Thanks in advance.
Edit:
I have tried it as a native query like
#Query(value = "Select Rule_Id, Rule_Sql,S_System,S_Entity, s_table_name,Rule_Sql_Type "
+ "FROM rule_master TRM ,T_SYSTEM_CONFIG TSC Where"
+ " Tsc.Parameter_Name='APPLICABLE_RULE_TYPE' "
+ " And Tsc.Parameter_KEY= :systemType"
+ " AND Tsc.Parameter_Value=trm.rule_type "
+ " And Rule_Status='ON'"
+ " Order By Rule_Priority", nativeQuery = true)
public List<RuleMaster> findByRuleStatus(#Param("systemType" String systemType);
but getting this error
o.h.engine.jdbc.spi.SqlExceptionHelper : SQL Error: 17006, SQLState: null
o.h.engine.jdbc.spi.SqlExceptionHelper : Invalid column name
org.springframework.orm.jpa.JpaSystemException: could not execute query; nested exception is org.hibernate.exception.GenericJDBCException: could not execute query
I was able to solve this by using native query itself.
The error was because i was selecting only part of the columns from the table. Instead i have used the below query which works fine:
#Query(value = "Select * "
+ "FROM rule_master TRM ,T_SYSTEM_CONFIG TSC Where"
+ " Tsc.Parameter_Name='APPLICABLE_RULE_TYPE' "
+ " And Tsc.Parameter_KEY= :systemType"
+ " AND Tsc.Parameter_Value=trm.rule_type "
+ " And Rule_Status='ON'"
+ " Order By Rule_Priority", nativeQuery = true)
public List<RuleMaster> findByRuleStatus(#Param("systemType" String systemType);
I am trying to write native query:
#NamedNativeQuery(name = "getUncheckedTests",
query = "SELECT t.test_name AS test_name, q.question AS question, #counter \\:= COUNT(ua.is_checked=0) AS uncheckedAnswers FROM user_answer ua" +
" JOIN result r on r.id = ua.result_id" +
" JOIN test t on r.test_id = t.id" +
" JOIN question q on ua.question_id = q.id" +
" WHERE r.is_checked = false AND q.is_open = true AND ua.is_checked = false" +
" AND r.test_id IN (SELECT t.id FROM result r" +
" JOIN test t on t.id = r.test_id" +
" JOIN user u on u.id = r.user_id" +
" WHERE r.permission = 2 AND u.id = :userId) and r.permission = 1 and #counter > 0" +
" GROUP BY ua.question_id")
However, i am getting empty result as #counter > 0 does not work properly. I can execute this query right in Workbench, however no result if it's put in Hibernate as native query
You should probably check the actual SQL Hibernate executes by enabling logging of the statements or by using log4jdbc and make sure you execute the query with the proper parameters.
I have a case similar to the one described in this question, I wrote an identical query which works, but when I try to write it as a jpql named query, I'm getting an error.
My query:
#NamedQuery(
name = "findRankingsBetween",
query = "SELECT rt FROM Rankingtable rt " +
"INNER JOIN " +
"(SELECT teamId, MAX(lastupdate) as MaxDateTime " +
"FROM Rankingtable " +
"GROUP BY teamId) grouped " +
"ON rt.teamId = grouped.teamId " +
"AND rt.lastupdate = grouped.MaxDateTime " +
"WHERE rt.lastupdate BETWEEN :from AND :to"
)
Error:
Error in named query: findRankingsBetween: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: ( near line 1, column 79
How to write the query properly in jpql?
As noted in this answer, a subquery in JPQL can only occur in select and where clauses.
Hibernate doc.
An equivalent query in JPQL is:
"SELECT rt FROM Rankingtable rt " +
"WHERE rt.lastupdate = (SELECT MAX(r2.lastupdate) " +
"FROM Rankingtable r2 " +
"WHERE r2.teamid = rt.teamid) " +
"AND rt.lastupdate BETWEEN :from AND :to"
I got this request :
TypedQuery<ParamGenerauxExternes> q = entityMgr
.createQuery("SELECT p FROM ParamGenerauxExternes p "
+ "WHERE EXISTS "
+ "(SELECT q FROM ParamGenerauxExternes q "
+ "WHERE q.key.origine = :pOrigine "
+ "AND q.key.typeParam LIKE :pTypeParametreBis "
+ "AND p.key.sousType LIKE CONCAT('%',q.libelleParam) "
+ "AND q.actif = 'Y') "
+ "ORDER BY p.libelleParam", ParamGenerauxExternes.class)
//.setParameter("pTypeParametre", "REL_TO_HOUSEHOLD")
.setParameter("pOrigine", pOrigineGrc)
.setParameter("pTypeParametreBis", "GRC_HOUSEHOLD_TYPE_P%");
But it doesn't work, I got this error message that tell a prenthesis is missing :
GRAVE: EJB Exception: : javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: ORA-00907: missing right parenthesis
The generated SQL by JPA has a parenthesis after the second select :
select
paramgener0_.CODE_PARAM as CODE1_2823_,
paramgener0_.ORIGINE as ORIGINE2823_,
paramgener0_.SOUS_TYPE as SOUS3_2823_,
paramgener0_.TYPE_PARAM as TYPE4_2823_,
paramgener0_.ACTIF as ACTIF2823_,
paramgener0_.LIBELLE_PARAM as LIBELLE6_2823_
from
FOA_PARAM_GEN_EXTERNE paramgener0_
where
exists (
select
(paramgener1_.CODE_PARAM,
paramgener1_.ORIGINE,
paramgener1_.SOUS_TYPE,
paramgener1_.TYPE_PARAM)
from
FOA_PARAM_GEN_EXTERNE paramgener1_
where
paramgener1_.ORIGINE=?
and (
paramgener1_.TYPE_PARAM like ?
)
and (
paramgener0_.SOUS_TYPE like '%'||paramgener1_.LIBELLE_PARAM
)
and paramgener1_.ACTIF='Y'
)
order by
paramgener0_.LIBELLE_PARAM
I don't know why hibernate add a parenthesis after the second select ? Please if you know what to do...
That query fails on Oracle but passes on, for example, Postgres. If you are using Oracle database, try setting Oracle SQL dialect to your JPA provider.
