I'm using R2DBC in my project. After upgrading to Spring Boot from 2.5.* to 2.6.1 my query:
#Query("SELECT EXISTS(SELECT 1 FROM some_link links WHERE links.data_id = $1 AND links.some_id != links.source_id)")
fun existsByDataIdAndLocked(dataId: UUID): Mono<Boolean>
Throws an exception:

Once I change $1 in the query to :dataId then it works.
Why is that? As per documentation, both are valid.
i have a problem.I explain my situation: SpringBoot + Hibernate + Multitenant (DB master + DB for tenant) + Postgressql. I have two datasource configurations, one for the master and one for each client's database. I need doing a query native in JPARepository And that's the only way I can do it
In my JPARepository :
public interface IEntity extends JpaRepository<Entity, Integer> {
........
#Query(value = "ALTER SEQUENCE entity_identity_seq RESTART", nativeQuery = true)
#Modifying ///Add 1
#Transactional ///Add 2
void restarID();
}
when I first call the method, I got:
> Hibernate:
ALTER SEQUENCE entity_identity_seq RESTART
> 2019-09-10 15:41:53.919 WARN 18680 --- [nio-8080-exec-2] o.h.engine.jdbc.spi.SqlExceptionHelper : SQL Error: 0, SQLState: 02000

org.postgresql.util.PSQLException: La consulta no retornó ningún resultado.
After looking for solutions and discovered that he needed to add
#Query(value = "ALTER SEQUENCE entity_identity_seq RESTART", nativeQuery = true)
#Modifying
void restarID();
But the query is not made in hibernate and this error comes up:
> 2019-09-10 15:46:57.972 ERROR 14392 --- [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessApiUsageException: Executing an update/delete query; nested exception is javax.persistence.TransactionRequiredException: Executing an update/delete query] with root cause

I keep searching and find that I should add #Transactional. Then :
#Query(value = "ALTER SEQUENCE entity_identity_seq RESTART", nativeQuery = true)
#Modifying
#Transactional
void restarID();
But, then come back, I call the method, I got:
> Hibernate:
ALTER SEQUENCE entity_identity_seq RESTART
> 2019-09-10 15:41:53.919 WARN 18680 --- [nio-8080-exec-2] o.h.engine.jdbc.spi.SqlExceptionHelper : SQL Error: 0, SQLState: 02000

Please, will anyone have any recommendations?
I am new to hibernate. Thank you.
If someone yet have the same problem, I've resolved it, adding the next to the query:
#Modifying(clearAutomatically = true)
#Transactional
I have a Spring Boot app that is using JPA and a Postgres table with ltree data structure.
It works when I query using sql statement but not when I pass an argument.
Controller
#GetMapping("/path")
ResponseEntity<?> findAllByPath() {
List<Tree> allByPath = treeRepository.findAllByPath("A");
return ResponseEntity.ok().body(allByPath);
}
Working Code in Repository
#Query(value = "SELECT * FROM Tree WHERE path <# 'A'", nativeQuery = true)
List<Tree> findAllByPath(#Param("pathToSearch") String pathToSearch);
*Not Working Code in Repository
#Query(value = "SELECT * FROM Tree WHERE path <# '" + ":pathToSearch" +"'", nativeQuery = true)

I had a project needs to set up SMS gateway that works with JAVA-EE project. GAMMU 1.36.0 was selected.
backend DB is Postgresql 9.4, table inbox and sequence were created to hold in come SMS.
inbox created by use:
CREATE TABLE inbox (
"UpdatedInDB" timestamp(0) WITHOUT time zone NOT NULL DEFAULT LOCALTIMESTAMP(0),
"ReceivingDateTime" timestamp(0) WITHOUT time zone NOT NULL DEFAULT LOCALTIMESTAMP(0),
"Text" text NOT NULL,
"SenderNumber" varchar(20) NOT NULL DEFAULT '',
"Coding" varchar(255) NOT NULL DEFAULT 'Default_No_Compression',
"UDH" text NOT NULL,
"SMSCNumber" varchar(20) NOT NULL DEFAULT '',
"Class" integer NOT NULL DEFAULT '-1',
"TextDecoded" text NOT NULL DEFAULT '',
"ID" serial PRIMARY KEY,
"RecipientID" text NOT NULL,
"Processed" boolean NOT NULL DEFAULT 'false',
CHECK ("Coding" IN
('Default_No_Compression','Unicode_No_Compression','8bit','Default_Compression','Unicode_Compression')));
id is a sequence number hold in:
--CREATE SEQUENCE inbox_ID_seq;
table structure looks like:
smsd-> \d inbox
Table "public.inbox"
Column | Type | Modifiers
-------------------+--------------------------------+----------------------------------------------------------------
UpdatedInDB | timestamp(0) without time zone | not null default ('now'::text)::timestamp(0) without time zone
ReceivingDateTime | timestamp(0) without time zone | not null default ('now'::text)::timestamp(0) without time zone
Text | text | not null
SenderNumber | character varying(20) | not null default ''::character varying
Coding | character varying(255) | not null default 'Default_No_Compression'::character varying
UDH | text | not null
SMSCNumber | character varying(20) | not null default ''::character varying
Class | integer | not null default (-1)
TextDecoded | text | not null default ''::text
ID | integer | not null default nextval('"inbox_ID_seq"'::regclass)
RecipientID | text | not null
Processed | boolean | not null default false
Indexes:
"inbox_pkey" PRIMARY KEY, btree ("ID")
Check constraints:
"inbox_Coding_check" CHECK ("Coding"::text = ANY (ARRAY['Default_No_Compression'::character varying, 'Unicode_No_Compression'::character varying, '8bit'::character varying, 'Default_Compression'::character varying, 'Unicode_Compression'::character varying]::text[]))
Triggers:
update_timestamp BEFORE UPDATE ON inbox FOR EACH ROW EXECUTE PROCEDURE update_timestamp()
smsd->
Please note: column ids' position is 10 in the table.
This table is working well with GAMMU 1.36.0, send and receive SMS properly.
When I try to develop a EJB to bring the inbox information to my web application.

try {

System.out.println("Records found: "+ todaysemails.size());
todaysemails.stream().forEach((e) -> {
System.out.println(e.getTextDecoded());
});
}catch (NamingException e) {
e.printStackTrace();
}
}
Everything is work fine so far. but very strange error thrown:

Java Result: 1
BUILD SUCCESSFUL (total time: 1 second)
seems PSQL trying find "id" column in position 8 instead of position 10 and actually "id" column located in position 10 in inbox table.
Any idea and advice please! Appreciated!!
Your problem is case-sensitivity: JPA works in case insensitive mode by default (i.e. it won't quote identifiers in its queries), while PostgreSQL will convert any unquoted identifiers to lower-case (this is the way PostgreSQL tries to achieve case insensitivity). But, you defined your "ID" column in case-sensitive mode (note the quotes).
An ugly workaround is, that you define your entity in a case-sensitive way:
#Column(name = "\"ID\"")
Or, you can define your table in a case-insensitive way (which is preferred):
CREATE TABLE inbox (
ID serial PRIMARY KEY
-- ...
);
Eventually. This issue was fixed by using native SQL query
Query query = em.createNativeQuery("Select * from inbox",com.longz.smsd.model.SmsdInboxEntity.class);
return new LinkedList<SmsdInboxEntity>(query.getResultList());
Seems JSQL is not 100% works in this situation.
This one will be help some one else who have the same issue.
I am new to JPA. I am using EclipseLink 2.5.2 against Oracle database with Oracle JDBC driver. For the simple code below:
public List<DummyGrp> findByProperty(String propertyName, Object value) {
CriteriaBuilder cb = entityManager.getCriteriaBuilder();
CriteriaQuery<DummyGrp> cq = cb.createQuery(DummyGrp.class);
Root<DummyGrp> rootQuery = cq.from(DummyGrp.class);
cq.select(rootQuery);
cq.where(cb.equal(rootQuery.get(propertyName),value));
TypedQuery<DummyGrp> q = entityManager.createQuery(cq);
return q.getResultList();
}
The result is always empty. After turning on debug, I did see the SQL:
[EL Fine]: sql: 2015-01-09 12:20:51.215--ClientSession(559179052)--Connection(1008188683)--Thread(Thread[main,5,main])--SELECT ID, DATA_TYPE_IND, ENTRY_TYPE_IND, GRP_DESC, GRP_NAME, TRANS_ORIG_MM, TRANS_ORIG_YR FROM DUMMY_GRP WHERE (GRP_NAME = ?)
bind => [TG_dabfe8]
I debugged the Oracle JDBC. I was able to debug JDBC to the point that I can see the client side Oracle Statement with bind parameter and if I run the statement directly from an IDE, I can get result expected.
If I change the "equal" operator to "like" (see below):
cq.where(cb.like(rootQuery.get(propertyName),value+"%"));
I get result back.
I am sure I might be missing something simple. Can anyone enlighten me?
Thanks in advance,
Peter C.
By the way, here is the Oracle JDBC Diagnositcs log:
