I'm trying to save a nested object using hibernate and I receive could not execute statement; SQL [n/a] Exception
CODE
#Entity
#Table(name = "listing")
#Inheritance(strategy = InheritanceType.JOINED)
public class Listing implements Serializable {
#Id
#Column(name = "listing_id")
private String listingId;
#Column(name = "property_type")
private PropertyType propertyType;
#Column(name = "category")
private Category category;
#Column(name = "price_currency")
private String priceCurrency;
#Column(name = "price_value")
private Double priceValue;
#Column(name = "map_point")
private MapPoint mapPoint;
#Column(name = "commission_fee_info")
private CommissionFeeInfo commissionFeeInfo;
}
public class MapPoint implements Serializable {
private final float latitude;
private final float longitude;
}
public class CommissionFeeInfo implements Serializable {
private String agentFeeInfo;
private CommissionFeeType commissionFeeType;
private Double value;
private Double commissionFee;
}
public enum CommissionFeeType implements Serializable { }
Using RazorSQL I saw that hibernate defines MapPoint and CommissionFee as VARBINARY
What I can't understand, is the fact that hibernate manages to save it when commissionFeeInfo is not present. It has no problem with saving MapPoint
Does anyone have an idea about what I do wrong?
UPDATE
I found out that if all attributes of CommissionFeeInfo excepting agentFeeInfoare null, the object will be saved without problems. If one of the other attributes is != null, the errors occur.
UPDATE 2
I changed the type of all attributes of CommissionFeeInfo into String and the object will be saved without problem, but I can't let the attributes as String.
I solved the problem by adding setting
#Column(name = "commission_fee_info", columnDefinition = "LONGVARBINARY")
as annotation for the field commisionFeeInfo in the class Listing
For me,
#Column(columnDefinition="text")
solves my problem.
That solution could help for a different reason. One other reason could be Column length. Check your column length. I had the same error the reason was my data exceed the size of the column.
setSignInProvider("String length > 15 ")
Before
#Column(name = "sing_in_provider", length = 15)
and then
#Column(name = "sing_in_provider", length = 100)
I was also facing the same issue . and then I solved the problem
spring.jpa.hibernate.ddl-auto=update
For me I'm using current_date for a field in my sql table. but this is a keyword in SQL so I can't use this name. I changed the field name to current_date_and_time it works for me. also I added the column name on my entity class.
#Column(name = "current_date_and_time")

I am currently working on a Java project with Hibernate entities (more below). In order to test my data access object layers, I am using H2 database to populate an in-memory database and throwing queries at it. Until this point, everything is fine.
However, the problem comes when simulating the #EmbeddedId annotation.
#Entity
#Table(name = "BSCOBJ")
public class BasicObject extends AbstractDomainObject {
#EmbeddedId // This annotation here
private RestrainPK restrain;
#Embeddable
public static class RestrainPK implements Serializable {
private static final long serialVersionUID = 1L;
#Column(name = "CODI", nullable = false)
private String coDi;
#Column(name = "COGA", nullable = false)
private String coGa;
#Column(name = "TYOR", nullable = false)
private String tyOr;
public RestrainPK() {
}
... // Getters and setters
}
}
"Simply" creating the table BSCOBJ and populating it gives no value when fetching data (of course, I checked that the request would give result "normally"). How do I represent this nested class in a SQL table creation / value insertion request ? Is that even possible ?
Thanks in advance,
EDIT
As requested, here is some samples about the SQL / Hibernate ran.
Creation request:
CREATE TABLE BSCOBJ (CODI VARCHAR(5) NOT NULL, COGA VARCHAR(5) NOT NULL, TYOR VARCHAR(5) NOT NULL);
Insertion request:
INSERT INTO BSCOBJ (CODI, COGA, TYOR) VALUES
('HELLO', 'MAT', 'REF'),
('BONJ', 'SOME', 'DAIL'),
('SOPA', 'KDA', 'RATIO');
Request given by Hibernate when trying to run the test code:
select r.restrain.tyOr from mypackage.BasicObject r where r.restrain.coDi = :coDi and r.restrain.coGa = :coGa
With the following values:
coDi = "BONJ";
coGa = "SOME";
Throws a NoResultException. I am expecting DAIL, from the second line of the INSERT request.
I have used #EmbeddedId only one time, but I think that you need #AttributeOverrides under your #EmbeddedId
#EmbeddedId
#AttributeOverrides({
#AttributeOverride(name = "idpk", column = #Column(name="IDPK", nullable = false),
#AttributeOverride(name = "code", column = #Column(name="CODE")
})
and remove your #Column annotations from FormulePK
I want to get some data from db using custom query.
#Query("select new com.myProject.UserConfDTO(cd.id, us.lastDeactivationTime, true) from UserConfig us " +
"join us.codes as cd where cd in :codes and us.userEnabled = 1 and us.state= 'ACTIVE'")
List<UserConfDTO> getAllEnabledUsersWithConf(#Param("codes") List<Codes> codes);
Codes.java:
#AllArgsConstructor
public class Codes{
private Integer id;
private String name;
}
UserConfDTO.java:
#AllArgsConstructor
public class UserConfDTO{
private Integer id;
private String name;
private Instant lastDeactivationTime;
private Boolean userEnabled;
}
UserConfig.java:
#Id
#GeneratedValue
private Long id;
#ElementCollection
#Builder.Default
private Set<Integer> codes = new HashSet<>();
private Instant lastDeactivationTime;
#Column(nullable = false)
private State state;
I would like to pass all Codes objects - check some things in db, and return prepared UserConfDT object. Unfortunately, It doesn`t work. I get exception:
IllegalArgumentException: Parameter value element [Codes(id=1234, name=test1)] did not match expected type [java.lang.Integer (n/a)]
I have UserConfig class/table with relation one-many with class/table Codes. One UserConfig can have more then one codes.
I want to pass List as parameter and fetch from UserConfig data (by each Codes ID property) --> next create via (select new..) UserConfDTO object.
Do you know how to do it?
I have a flink project that will be inserting data in a cassandra table as a batch job. I already have a flink stream project where it is writing a pojo to the same cassandra table, but cassandraOutputFormat needs the data as a Tuple (hope that is changed to accept pojos like CassandraSink does at some point). So here is the pojo that I have that:
#Table(keyspace="mykeyspace", name="mytablename")
public class AlphaGroupingObject implements Serializable {
#Column(name = "jobId")
private String jobId;
#Column(name = "datalist")
#Frozen("list<frozen<dataobj>")
private List<CustomDataObj> dataobjs;
#Column(name = "userid")
private String userid;
//Getters and Setters
}
And the dataset of tuple I am making from this pojo:
DataSet<Tuple3<String, List<CustomDataObj>, String>> outputDataSet = listOfAlphaGroupingObject.map(new AlphaGroupingObjectToTuple3Mapper());
And here is the line that triggers the output as well:
outputDataSet.output(new CassandraOutputFormat<>("INSERT INTO mykeyspace.mytablename (jobid, datalist, userid) VALUES (?,?,?);", clusterThatWasBuilt));
Now the issue that I have is when I try to run this, I get this error when it tries to output it to the cassandra table:
Caused by: com.datastax.driver.core.exceptions.CodecNotFoundException:
Codec not found for requested operation: [frozen<mykeyspace.dataobj> <-> flink.custom.data.CustomDataObj]
So I know when it was a pojo, I just had to add the #Frozen annotation to the field, but I don't know how to do that for a tuple. What is the best/proper way to fix this? Or am I doing something unnecessary because there is actually a way to send pojos through the cassandraOutputFormat I just haven't found?
Thanks for any and all help in advance!
EDIT:
Here is the code for the CustomDataObj class too:
#UDT(name="dataobj", keyspace = "mykeyspace")
public class CustomDataObj implements Serializable {
#Field(name = "userid")
private String userId;
#Field(name = "groupid")
private String groupId;
#Field(name = "valuetext")
private String valueText;
#Field(name = "comments")
private String comments;
//Getters and setters
}
EDIT 2
Including the table schema in cassandra that the CustomDataObj is tied to and the mytablename schema.
CREATE TYPE mykeyspace.dataobj (
userid text,
groupid text,
valuetext text,
comments text
);
CREATE TABLE mykeyspace.mytablename (
jobid text,
datalist list<frozen<dataobj>>,
userid text,
PRIMARY KEY (jobid, userid)
);
Add UDT Annotation on CustomDataObj class
#UDT(name = "dataobj")
public class CustomDataObj {
//......
}
Edited
Change jobid Annotation to #Column(name = "jobid") and dataobjs Frozen Annotation to #Frozen
#Table(keyspace="mykeyspace", name="mytablename")
public class AlphaGroupingObject implements Serializable {
#Column(name = "jobid")
private String jobId;
#Column(name = "datalist")
#Frozen
private List<CustomDataObj> dataobjs;
#Column(name = "userid")
private String userid;
//Getters and Setters
}
I believe I have found a better way than having to provide a tuple to the cassandraOutputFormat, but it technically still doesn't answer this question so I won't mark this as the answer. I ended up using cassandra's object mapper so I can just send the pojo to the table. Still need to validate that data got to the table successfully and that everything is working properly with the way it is implemented, but I felt this would help anyone who is facing a similar problem.
Here is the doc that outlines the solution: http://docs.datastax.com/en/developer/java-driver/2.1/manual/object_mapper/using/
I am trying to use hibernate annotations for getting data from a MySQL database table which doesn't have a primary key defined.
However the fact is 2 columns of that table together are unique in the table. How can I achieve the same using hibernate annotation?
This is my code
#Entity
#Table(name = "coc_order_view")
public class CoCOrderDetailsTest {
#EmbeddedId
private MyJoinClassKey key;
#Column(name = "coupon_code")
private String couponCode;
some other columns and their getters and setters .....
#Embeddable
public class MyJoinClassKey implements Serializable {
private static final long serialVersionUID = -5L;
#Column(name = "product_id")
private int productId;
#Column(name = "order_id")
private int orderId;
gettes and setters....
And here is my criteria query
Criteria criteria = getHibernatetemplate().getSession().createCriteria(CoCOrderDetailsTest.class);
criteria.add(Restrictions.eq("status", "New"));
ArrayList<CoCOrderDetailsTest> orderDet = (ArrayList<CoCOrderDetailsTest>) getHibernatetemplate().get(criteria);
I am unable to get all the values from db. Kindly suggest some solutions.
After reading through your question again not sure this will help. You can't have a table without primary key(s). Read the first couple of paragraphs in this article
That said, if you can alter the table and add primary keys on those fields you need to add #IdClass annotation to your class signature for CoCOrderDetailsTest and then get rid of the #embeddable and #embeddedId notation in your classes.
Another alternative, if you can add a field to the table, would be to use an #GeneratedValue on that added primary key field and of course annotate it with #Id.
If you can't alter the table then you can't use JPA and you'll have to use JDBC.
See http://docs.oracle.com/javaee/5/api/javax/persistence/IdClass.html
A working example:
#Entity
#Table(name = "player_game_log")
#IdClass(PlayerGameLogId.class)
public class PlayerGameLog {
#Id
#Column(name = "PLAYER_ID")
private Integer playerId;
#Id
#Column(name = "GAME_ID")
private String gameId;
....
and the id class (note there are no annotations on the id class)....
public class PlayerGameLogId implements Serializable {
private static final long serialVersionUID = 1L;
private Integer playerId;
private String gameId;
Try:
String hql = "FROM CoCOrderDetailsTest WHERE status = :status";
Query query = session.createQuery(hql);
query.setParameter("status","New");
List results = query.list();
I usually use EntityManager rather than session so I'm not familiar with this syntax - and I have typically added a type to the list to be returned - like:
List<CoCOrderDetailsTest> results = query.list();
I have a domain object and annotated as follows
#Entity
#Table(name = "REQUEST")
public class Request {
/**
* Unique id for this request
*/
#Id
#GeneratedValue
#Column(name = "EQ_ID")
private long requestId;
/**
*
*/
#Column(name = "EMAIL_ID")
private String emailId;
/**
*
*/
#Column(name = "REQUEST_DATE")
private Date requestDate;
/**
*Getters/setters omitted
*/
}
The column Request_date cannot be null and as per the DDL the default value is sysdate (oracle DB). How do I annotate this field so that if the requestDate property is null,hiberanate automatically inserts sysdate.? Currently it throws error when the field is null,which is very obvious as it cannot be null as per the DB constraints. How do I go about this?
One alternative is to mark this field as transient and the inserts work fine. But the negative aspect is that, I will not be able to retrieve the value (of request_date column).
This is a missing feature in hibernate annotations. Also there exist some workaround as Yok has posted. The problem is that the workaround is vendor dependent and might not work for all DB. In my case,Oracle, it isn't working and has been reported as a bug.
You can put the default value in a columnDefinition. An example would look like:
#Column(name = "REQUEST_DATE", nullable = false, columnDefinition = "date default sysdate")
Using #ColumnDefault (Work for DDL update).
hibernate.hbm2ddl.auto=update
import org.hibernate.annotations.ColumnDefault;
....
#ColumnDefault(value="'#'")
#Column(name = "TEMP_COLUMN", nullable = false)
public String getTempColumn() {
return tempColumn;
}
DDL Generate:
Alter Table YOUR_TABLE add TEMP_COLUMN varchar2(255) default '#' not null;
Assign a default value to the field:
private Date requestDate = new Date();
If you mark your entity with #DynamicInsert e.g.
#Entity
#DynamicInsert
#Table(name = "TABLE_NAME")
public class ClassName implements Serializable {
Hibernate will generate SQL without null values. Then the database will insert its own default value. This does have performance implications See Dynamic Insert.
Make the default in Oracle for the column SYSDATE:
ALTER TABLE APP MODIFY (REQUEST_DATE DEFAULT SYSDATE);
Then, from Hibernate's perspective it can be nullable.
Hibernate will save a NULL to the database. Oracle will convert that to SYSDATE. And everyone will be happy.
I resolved assigning a value to the variable like this private Integer active= 0;
#Entity
#Table(name="products")
public class ServiziTipologia {
#Id
#GeneratedValue
private Integer id;
private String product;
private String description;
private Integer active= 0;
