only select columns of the a psql table could receive data

Something very bizarre have been happening. I have a very simple Entity recipe like so
#Data
#Entity
#Table(name = "recipe", schema = "public")
#AllArgsConstructor
#NoArgsConstructor
public class Recipe {
#Id
#GeneratedValue(
strategy = GenerationType.IDENTITY
)
#Column(name = "id", updatable = false, nullable = false)
private long id;
#Column(name = "name")
private String name;
#Column(name = "instructions")
private String instructions;
#Column(name = "date_added", nullable = false)
private String dateAdded;
#Column(name = "last_edited", nullable = false)
private String lastEdited;
}
and I have this post service that should post the 4 string attribute to the database
public void postRecipe(Recipe recipe){
var sql = """
INSERT INTO public.recipe ("name","instructions","date_added","last_edited")
VALUES (?, ?, ?, ?)
""";
jdbcTemplate.update(
sql,
recipe.getName(),
recipe.getInstructions(),
recipe.getDateAdded(),
recipe.getLastEdited()
);
}
However when the following jason is sent using postman, I get the null value error.
{
"name":"test",
"instructions":"don't eat",
"date_added":"03/04/2017",
"last_edited":"03/04/2017"
}
ERROR: null value in column \"date_added\" of relation \"recipe\" violates not-null constraint\n Detail: Failing row contains (3, null, don't eat, null, test)
The strangest thing is that only the "name" and "instruction" columns receive their data and not the other columns. I have tried adding another String attribute to the Entity class and it also cannot get data from the jason.
Edit 1:
I have tried adding the data directly through pgadmin and it worked fine
INSERT INTO recipe (name, instructions, date_added, last_edited)
VALUES ('test', 'test instruction', '2020/03/05', '2020/05/08');

It looks like your deserialization is broken - transforming your JSON into the Java entity, which results in some null values present. Most likely because date_added != dateAdded (field name), and Jackson cannot properly set a value.
I recommend having a look at Jackson guide: https://www.baeldung.com/jackson-annotations, #JsonProperty specifically. And overall do not mix entities and DTOs

After many trials and errors I was able to come up with a solution but still have no clue as to why this is happening. It turns out the under score in the annotation is the problem.
//won't work
#Column(name = date_added)
//works
#Column(name = dateadded)
This is pretty strange because I am fairly certain that the under score is generated by hibernate.
if anyone know why this is happening please let me know... for now I will just stay away from the under scrolls.

Primary key not returned in OneToOne join fetch in eclipselink

I have an issue join fetching in case of OneToOne relation in the same class. Example follows:
class Data {
...
#Id
#Column(name = "DATA_ID")
Long id;
#Column(name = "DATA_OWNER_ID")
#ForeignKey(entityClass = Owner.class)
Long ownerId;
#Column(name = "DATA_RELATED_ID")
#ForeignKey(entityClass = Data.class)
Long relatedDataId;
#OneToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "DATA_RELATED_ID", referencedColumnName = "DATA_ID", insertable = false, updatable = false)
Data relatedData;
}
I want to select data based on some conditions, while also fetching/initialising the "relatedData", all in one JPQL query:
SELECT owner.something1, data
FROM Data data
JOIN Owner owner on data.ownerId = owner.id
JOIN FETCH data.relatedData
WHERE data.something2 = :expectedSomething2
Executing that JPQL query throws an exception:
Query: ReadObjectQuery(name="relatedData" referenceClass=Data)|Exception:
javax.persistence.PersistenceException: Exception [EclipseLink-6044] (Eclipse Persistence Services - 2.6.2.v20151217-774c696): org.eclipse.persistence.exceptions.QueryException
Exception Description: The primary key read from the row [DatabaseRecord(
DATA_X => something
DATA_Y => something2
...
)] during the execution of the query was detected to be null. Primary keys must not contain null.
Which is somewhat true, as there is no DATA_ID column listed. Changing JOIN FETCH to LEFT JOIN FETCH returns both owner.something1 and data, but the relatedData object is null (relatedDataId is not null).
I can see, that the id for relatedData is returned from DB, but eclipselink trims it in valueFromRowInternalWithJoin and trimRowForJoin methods.

The Id column name attribute value is the reason of this exception. Same issue found in eclipselink version 2.3.2 but it works fine in version 2.0.0
Try with this entry :
eclipselink.jpa.uppercase-column-names=true
OR Try with upper and lower case one by one which on will work for you.
#Id
#Column(name = "UUID") // UUID - uppercase/lowercase one by one
Long id;

I've somehow resolved this issue, but haven't had the time to correctly identify the cause. Final (working) version differences are:
I could've forgotten to add get/set for relatedData
I have specified targetEntity = Data.class in #OneToOne
Fetch is now a LEFT JOIN FETCH and appears before JOIN Owner owner

Spring JPA hibernate postgresql partion and timestamp without timezone

After searching a lot, I have a trouble to save timestamp data in PostgreSQL base using Spring JPA Hibernate.
Here my main table in PostgreSQL, it's a partitionning table :
CREATE TABLE public.archive_traffic_measure
(
measure_point_id integer NOT NULL,
measure_agregation_id integer NOT NULL,
measure_datetime timestamp without time zone NOT NULL,
measure_type_id integer NOT NULL,
any_flow integer,
f_any_flow smallint,
hgv_flow integer,
f_hgv_flow smallint,
occupation_rate smallint,
f_occupation_rate smallint,
average_speed smallint,
f_average_speed smallint,
CONSTRAINT pk_archive_traffic_measure PRIMARY KEY (measure_point_id, measure_agregation_id, measure_datetime, measure_type_id)
)
Here my main entity with spring JPA hibernate with #SQLInsert to suppress the check and don't have the problem with hibernate that no row is insert (because the row is insert in a child table) :
#Entity
#Table(name = "archive_traffic_measure")
#SQLInsert(sql = "INSERT INTO archive_traffic_measure (measure_point_id," +
"measure_agregation_id," +
"measure_datetime," +
"measure_type_id," +
"any_flow," +
"f_any_flow," +
"hgv_flow," +
"f_hgv_flow," +
"occupation_rate," +
"f_occupation_rate," +
"average_speed," +
"f_average_speed) VALUES (?,?,?,?,?,?,?,?,?,?,?,?)", check = ResultCheckStyle.NONE)
public class ArchiveTrafficMeasure implements Serializable {
#EmbeddedId
private ArchiveTrafficMeasureId id;
#Column(name = "any_flow")
private Integer anyFlow;
#Column(name = "f_any_flow")
private Integer F_AnyFlow;
#Column(name = "hgv_flow")
private Integer hgvFlow;
#Column(name = "f_hgv_flow")
private Integer F_hgvFlow;
#Column(name = "occupation_rate")
private Integer occupationRate;
#Column(name = "f_occupation_rate")
private Integer F_occupationRate;
#Column(name = "average_speed")
private Integer averageSpeed;
#Column(name = "f_average_speed")
private Integer F_averageSpeed;
}
And my id's entity with Spring JPA hibernate :
#Embeddable
#Table(name = "archive_traffic_measure")
public class ArchiveTrafficMeasureId implements Serializable {
#Column(name = "measure_point_id")
private int measurePointId;
#Column(name = "measure_agregation_id")
private int measureAgregationId;
#Column(name = "measure_datetime", columnDefinition = "timestamp without time zone")
#Temporal(TemporalType.TIMESTAMP)
private Date measureDateTime;
#Column(name = "measure_type_id")
private int measureType;
}
When I try to insert new data I have this error :
ERROR: column "measure_datetime" is of type timestamp without time zone but
expression is of type integer
The problem is the request be like :
INSERT INTO archive_traffic_measure VALUES (1,2,2018-04-18 17:00:00+01,1,40,null,null,null,null,null,null,null)
So the quote arount the timestamp is missing...
I have try to put the quote in the #SQLInsert "(?,?,'?',?,?,?,?,?,?,?,?,?)" but with that, I have the error :
The column's index is out of bound : 12, number of column : 11.
I have also try "(?,?,''?'',?,?,?,?,?,?,?,?,?)" with double quote
Or "(?,?,?::timestamp,?,?,?,?,?,?,?,?,?)" but nothing is working for far.
Can someone help me ? Thanks in advance.

First, add nullable = false for 'measure_datetime' column definition also remove composite key from #SQLInsert:
#SQLInsert(sql = "INSERT INTO archive_traffic_measure ("any_flow," +
"f_any_flow," +
"hgv_flow," +
"f_hgv_flow," +
"occupation_rate," +
"f_occupation_rate," +
"average_speed," +
"f_average_speed) VALUES (?,?,?,?,?,?,?,?,?)", check = ResultCheckStyle.NONE)
Then, when you persist ArchiveTrafficMeasure, you should set PK as ArchiveTrafficMeasureId and persist it.

JPA + Hibernate, bulk delete with IS NULL, SQL command not properly ended

I am trying to do a bulk delete.
Query queryDeleteEntries = entityManager.createQuery("DELETE from
Entry r where (r.person.emailAddress like :name) and (r.otherData is null)");
int deletedEntriesCount = queryDeleteEntries.setParameter("name",
"tester." + emailAddressSuffix).executeUpdate();
I am getting an error:
Caused by: java.sql.SQLException: ORA-00933: SQL command not properly ended
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112) ~[DatabaseError.class:Oracle JDBC Driver version - "10.2.0.2.0"]
Without "and r.otherData is null" it works, so I don't see what the problem is with that?
otherData is a list and it is defined in the Entry class that way:
#OneToMany(fetch = FetchType.EAGER)
#JoinColumn(name = "ENTRY_ID", referencedColumnName = "ID")
private List<OtherData> otherData;
OtherData (name changed) class:
#Entity
#Table(name = "OTHERDATA")
#SequenceGenerator(name = "SEQ", allocationSize = 1, sequenceName = "SEQ_OTHERDATA_ID")
public class OtherData {
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEQ")
private Long id;
...
#Column(name = "ENTRY_ID")
private Long entryId;
Can I not use "is null" on lists?
EDIT
I tried it with "size(r.otherData) = 0" and with "r.otherData IS EMPTY", but both led to the same exception.
What DOES work is this:
Query queryDeleteEntries = entityManager.createQuery("DELETE from Entry r where id in "
+ "(select id from Entry r2 where r2.person.emailAddress like :name"
+ " and not exists (select 1 from OtherData a where a.entryId = r2.id))");
int deletedEntriesCount = queryDeleteEntries.setParameter("name", "tester."+emailAddressSuffix).executeUpdate();
But I think it shouldn't be that complicated! Isn't there an easier way to do that?
Thanks in advance for any hints!

I would recommend taking the generated query and see how hibernate is translating to native Oracle query, by logging the hibernate packages or simply make add this to hibernate.cfg.xml :
<property name="show_sql">true</property>
also try to add .otherData.idOtherData just to see the behaviour.

JPA: one-to-one + self referential + bidirectional

I have an entity called 'Instructions'. Sometimes each Instructions has to keep track Instructions before and after it. For Example I have new instruction B which is continuing from existing instruction A, Instruction B has to aware that Instruction A is the previous instruction, while Instruction A also has to know that Instruction B is the next after it. Not every Instruction will have before and after Instruction.
How to implement this in JPA(EclipseLink): [one-to-one + self referential + bidirectional] relation?
So far (not working yet) i came up with this:
mysql db:
CREATE TABLE instructions (
instruction_id int(11) NOT NULL AUTO_INCREMENT,
instruction_title varchar(100) NOT NULL,
instruction_text varchar(999) NOT NULL,
instruction_previous_id int(11) DEFAULT NULL,
PRIMARY KEY (instruction_id),
CONSTRAINT instructions_ibfk_3
FOREIGN KEY (instruction_previous_id)
REFERENCES instructions (instruction_id));
entity:
#Entity
#Table(name = "instructions")
public class Instructions implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Basic(optional = false)
#Column(name = "instruction_id")
private Integer instructionId;
#Basic(optional = false)
#Column(name = "instruction_title")
private String instructionTitle;
#Basic(optional = false)
#Column(name = "instruction_text")
private String instructionText;
#JoinColumn(name="instruction_previous_id", referencedColumnName = "instruction_id", nullable = true)
#OneToOne(optional = true)
private Instructions instructionPrevious;
#OneToOne(cascade = CascadeType.ALL, mappedBy = "instructionPrevious")
private Collection<Instructions> instructionNextCollection;
// other properties, setter & getter
}
Currently no problem at create new Instruction, had error at reading
Instructions instruction = em.find(Instructions.class, instructionId);
instruction.getInstructionNextCollection().size(); //error this line

There's some confusion in your example whether each Instruction can be followed by a single Instruction or by many.
If it's a single, then don't use a collection for instructionNext.
If it's many, then the example code in JPA: How to have one-to-many relation of the same Entity type should help. You need #ManyToOne for the preceding instruction and #OneToMany for the following, rather than #OneToOne.
