I'm using subselect in hibernate to return an object that contains id on all related table instead of object.
this the dto that I defined
#Entity
#Subselect("select di.id as id, user.id as userId, client.id as clientId, controller.id as controllerId,"
+ "supplier.id as supplierId, grade.id as gradeId, packing.id as packingId, warehouse.id as warehouseId,"

+ "di.clientRef as clientRef,"
+ "di.date as date,"
+ "di.supplierRef as supplierRef,"

and in the DAO class, the method looks like below
public DeliveryView getDiById(int id) {
return (DeliveryView) getHibernateTemplate().get(DeliveryView.class, id);
}
However when I use the above method, it returned null.
When I run the method, the script that is printed to the console is

it gets the data from DeliveryView table which does not exist, what I want is to get the data from DeliveryInstruction table. Please help me to correct it, thanks
P/s: I'm using spring and hibernate and I do this way to work with jackson to prevent it load a lot of redundant information (I used jackson hibernate module, but it returned a lot of unneccessary information, instead of only id). So if you have any better idea, please tell me, thanks.
Update: I saw that the script on #subselect didn't run, it execute the default script "select * from deliveryView" when I call "get(DeliveryView.class, id)" method.
Update: This my native script that I've checked

String getManagerId();
LocalDate getExpectedDeliveryDate();
int getTotalCount();
int getOnTimeCount();
int getLateCount();
int getPendingCount();
int getNotReceivedCount();
}
getDailyDeliveryStatusSummaryByManagers works as expected.
But I need to have an opportunity to change group by section of this query on-the-fly, depending on user's input. So I decided to play with query as a plain string.
The idea is to put a query to string, and then depending on user's input, make query.replace('group placeholder', group by <needed list of fields>).
In order to archive this, I created a custom DeliveryStatusSummaryCustomRepository.
I decided not to make replace on a string so far, but to try to execute a simple query MANAGER_DELIVERY_QUERY.
public interface DeliveryStatusSummaryCustomRepository {
List<DeliveryStatusSummaryByManagerAndDate> getDailyDeliveryStatusSummaryByManagersV2();
}
#Repository
public class DeliveryStatusSummaryCustomRepositoryImpl implements DeliveryStatusSummaryCustomRepository {
private String MANAGER_DELIVERY_QUERY_TRY = "SELECT '1' AS managerId, " +
"CAST(dss.expected_delivery_date AS DATE) AS expectedDeliveryDate, " +
"0 AS totalCount, " +
"0 AS onTimeCount, " +
"0 AS lateCount, " +
"0 AS pendingCount, " +
"0 AS notReceivedCount " +
"FROM dsd.delivery_status_summary AS dss " +
"WHERE dss.expected_delivery_date >= CAST('01-01-2022' AS TIMESTAMP) AND dss.expected_delivery_date <= CAST('10-01-2022' AS TIMESTAMP)";
private final PrimaryDbConfig primaryDbConfig;
public DeliveryStatusSummaryCustomRepositoryImpl(PrimaryDbConfig primaryDbConfig) {
this.primaryDbConfig = primaryDbConfig;
}
#Override
public List<DeliveryStatusSummaryByManagerAndDate> getDailyDeliveryStatusSummaryByManagersV2() {
final LocalContainerEntityManagerFactoryBean em = primaryDbConfig.primaryEntityManager();
final EntityManager nativeEntityManager = em.createNativeEntityManager(new HashMap<>());
final Query query = nativeEntityManager.createQuery(MANAGER_DELIVERY_QUERY_TRY);
return query.getResultList();
}
}
But I got an error:

I believe that the issue is related to DeliveryStatusSummaryByManagerAndDate is not entity, this is just projection.
If so, what approach to use for writing dynamic query taking into account that MANAGER_DELIVERY query is quite complicated to be re-written with Hibernate joins?
I heard about https://www.jooq.org.
Any advice appreciated.
You need to use EntityManager.createNativeQuery() method.
Also you can just autoware EntityManager
#Repository
public class DeliveryStatusSummaryCustomRepositoryImpl {
#PersistenceContext
private EntityManager entityManager;
}
To map query results to DTO
Replace the interface DeliveryStatusSummaryByManagerAndDate with POJO with getters and setters.
Use a result transformer from Hibernate
import org.hibernate.query.Query;
Query<DeliveryStatusSummaryByManagerAndDate> query = entityManager
.createNativeQuery(sql)
.unwrap(Query.class)
.setResultTransformer(
Transformers.aliasToBean(DeliveryStatusSummaryByManagerAndDate.class)
);
return query.getResultList();
Also check this mapping Hibernate query results to custom class?
Given :
#Entity
public class entity_details {
#Id
private int id;
#column(name ="entity_id")
private int entityId;
#column(name="att_id")
private int attId;
#column(name="att_value")
private string attVal;
I want to find a equivalent query to the below one
select entity_id from entity_details where att_id=15 and att_value='test'
intersect
select entity_id from entity_details where att_id=18 and att_value='test2';
using CriteriaQuery only.
It is a complex operation, you could try something like this:
CriteriaBuilder cb = entityManager.getCriteriaBuilder();
CriteriaQuery<Long> cq = cb.createQuery(Long.class);
Root<EntityDetails> root = cq.from(EntityDetails.class);
Subquery<EntityDetails> sq = cq.subquery(EntityDetails.class);
Root<EntityDetails> rootSQ = cq.from(EntityDetails.class);
sq.where(
cb.and(
cb.and(
cb.equal(rootSQ.get("attId"),18),
cb.equal(rootSQ.get("attValue"),"test2")
),
cb.equal(rootSQ.get("id"),root.get("id"))
)
);
cq.where(
cb.and(
cb.and(
cb.equal(root.get("attId"),15),
cb.equal(root.get("attValue"),"test")
),
cb.exist(sq)
)
);
cq.multiselect(root.get("entityId"));
What would generate the following Query:
select e1.entity_id from entity_details e1
where e1.att_id = 15 and e1.att_value = "test"
and exists(
select * from entity_details e2
where e2.att_id = 18 and e2.att_value = "test2"
and e1.id = e2.id
)
I am using Spring Data JPA with native queries like below
public interface ItemRepository extends JpaRepository<ItemEntity, Long> {
#Query(value = "select * from items i where i.category = :itemCategory and i.item_code = :itemCode", nativeQuery = true)
Page<ItemEntity> search(#Param("itemCategory") String itemCategory, #Param("itemCode") String itemCode, Pageable pageable);
}
Now, my use case is
It itemCode is available, only the item with that code from that category should be returned.
But if itemCode is not available then all items in that category should be returned.
So the problem with the above category is when itemCode is passed as NULL no data is returned since it does not match anything. whereas the requirement is it should be ignored.
So is there a way to optionally add a clause to Spring Data JPA native query. I know it is possible with CriteriaQuery but can we do something similar for native queries?
Thanks
Yes, it's feasible with native query too. Very Good explanation here read this
#Approach1
#NamedQuery(name = "getUser", query = "select u from User u"
+ " where (:id is null or u.id = :id)"
+ " And :username"
:itemCode is null or i.item_code = :itemCode
#Approach2
# UserDao.java
public User getUser(Long id, String usename) {
String getUser = "select u from user u where u.id " + Dao.isNull(id)
+ " And u.username " + Dao.isNull(username);
Query query = Dao.entityManager.createQuery(getUser);
}
# Dao.java
public static String isNull(Object field) {
if (field != null) {
if (field instanceof String) {
return " = " + "'" + field + "'";
} else {
return " = " + field;
}
} else {
return " is NULL ";
}
}
How to handle null value of number type in JPA named query
Just modify the where condition
i.item_code = :itemCode
to
:itemCode is null or i.item_code = :itemCode
I have the following service method:
public Page<ProductSalesReportLineDto> getReport(
Unit unit, Organization customer, Organization supplier, Date startDate, Date endDate, Pageable pageable
){
List<ProductSalesReportLineDto> lines = new ArrayList<ProductSalesReportLineDto>();
String sql = "SELECT product.id, product.code as code, product.barcode as barcode, product_name.name__text AS name, " +
"SUM(order_line.quantity) as quantity, SUM(order_line.commissioned_price_price * order_line.quantity) as price " +
"FROM product LEFT JOIN order_line ON order_line.product_id = product.id " +

"AND (:unit is null OR :unit='' OR product.unit = :unit) " +
"GROUP BY product.id, product_name.name__text " +
"LIMIT :offset, :pageSize";
Map<String, Object> parameters = new HashMap<String, Object>();
parameters.put("offset", pageable.getOffset());
parameters.put("pageSize", pageable.getPageSize());
parameters.put("customer", customer != null ? customer.id : null);
parameters.put("supplier", supplier != null ? supplier.id : null);
parameters.put("startDate", startDate);
parameters.put("endDate", endDate);
parameters.put("unit", unit);
List<Map<String, Object>> rows = namedParameterJdbcTemplate.queryForList(sql, parameters);
for (Map<String, Object> row : rows) {
ProductSalesReportLineDto line = new ProductSalesReportLineDto();
line.productName = row.get("name") != null ? row.get("name").toString() : "";
line.productCode = row.get("code") != null ? row.get("code").toString() : "";
line.productBarcode = row.get("barcode") != null ? row.get("barcode").toString() : "";
line.quantity = row.get("quantity") != null ? Double.parseDouble(row.get("quantity").toString()) : 0;
line.price = row.get("price") != null ? Double.parseDouble(row.get("price").toString()) : 0;
lines.add(line);
}
Page<ProductSalesReportLineDto> page = new PageImpl<ProductSalesReportLineDto>(lines);
return page;
}
The parameters come from a #RestController method:
public #ResponseBody
ResponseEntity<?> get(
#RequestParam(value = "unit", required = false) Unit unit,
#RequestParam(value = "customer", required = false) Organization customer,
#RequestParam(value = "supplier", required = false) Organization supplier,
#DateTimeFormat(pattern = "yyyyy-MM-dd") #RequestParam(value = "startDate", required = false) Date startDate,
#DateTimeFormat(pattern = "yyyyy-MM-dd") #RequestParam(value = "endDate", required = false) Date endDate,
Pageable pageable
)
And Unit is an enum type field on Product:
#Enumerated(EnumType.STRING)
public Unit unit;
public enum Unit {
ROLL("ROLL", "ROLL", AbstractUnit.ONE),
METRE("METRE", Units.METRE.getSymbol(), Units.METRE),
KILOGRAM("KILOGRAM", Units.KILOGRAM.getSymbol(), Units.KILOGRAM),
PIECE("PIECE", "PIECE", AbstractUnit.ONE),
SAMPLE("SAMPLE", "SAMPLE", AbstractUnit.ONE);
I cannot retrieve products by unit using this query. With MySql the query works fine and it returns records. For example:
SELECT product.id, product.code as code, product.barcode as barcode, product_name.name__text AS name, SUM(order_line.quantity) as quantity, SUM(order_line.commissioned_price_price) as price FROM product LEFT JOIN order_line ON order_line.product_id = product.id JOIN `order` ON order_line.order_id = `order`.id JOIN product_name ON product_name.product_id = product.id WHERE product_name.name__locale = "en-US" AND (null is null OR null='' OR `order`.customer_id = null) AND (null is null OR null='' OR `order`.supplier_id = null) AND (null is null OR null='' OR `order`.date >= null) AND (null is null OR null='' OR `order`.date <= null) AND ("ROLL" is null OR "ROLL"='' OR product.unit = "ROLL") GROUP BY product.id, product_name.name__text
This query returns one row. When I run the same query via the rest interface and NamedParameterJdbcTemplate it returns no records. Can anybody tell what I am missing?
Following code also returns one row:
String sql2 = "SELECT * FROM product WHERE product.unit = :unit";
Map<String, Object> parameters2 = new HashMap<String, Object>();
parameters2.put("unit", "ROLL");
List<Map<String, Object>> rows2 = namedParameterJdbcTemplate.queryForList(sql2, parameters2);
I am trying to update certain rows in my oracle DB using id which is of RAW(255).
Sample ids 0BF3957A016E4EBCB68809E6C2EA8B80, 1199B9F29F0A46F486C052669854C2F8...
#Autowired
private NamedParameterJdbcTemplate jdbcTempalte;
private static final String UPDATE_SUB_STATUS = "update SUBSCRIPTIONS set status = :status, modified_date = systimestamp where id in (:ids)";
public void saveSubscriptionsStatus(List<String> ids, String status) {
MapSqlParameterSource paramSource = new MapSqlParameterSource();
List<String> idsHexToRaw = new ArrayList<>();
String temp = new String();
for (String id : ids) {
temp = "hextoraw('" + id + "')";
idsHexToRaw.add(temp);
}
paramSource.addValue("ids", idsHexToRaw);
paramSource.addValue("status", status);
jdbcTempalte.update(*UPDATE_SUB_STATUS*, paramSource);
}
This above block of code is executing without any error but the updates are not reflected to the db, while if I skip using hextoraw() and just pass the list of ids it works fine and also updates the data in table. see below code
public void saveSubscriptionsStatus(List<String> ids, String status) {
MapSqlParameterSource paramSource = new MapSqlParameterSource();]
paramSource.addValue("ids", ids);
paramSource.addValue("status", status);
jdbcTempalte.update(UPDATE_SUB_STATUS, paramSource);
}
this code works fine and updates the table, but since i am not using hextoraw() it scans the full table for updation which I don't want since i have created indexes. So using hextoraw() will use index for scanning the table but it is not updating the values which is kind of weird.
Got a solution myself by trying all the different combinations :
#Autowired
private NamedParameterJdbcTemplate jdbcTempalte;
public void saveSubscriptionsStatus(List<String> ids, String status) {
String UPDATE_SUB_STATUS = "update SUBSCRIPTIONS set status = :status, modified_date = systimestamp where id in (";
MapSqlParameterSource paramSource = new MapSqlParameterSource();
String subQuery = "";
for (int i = 0; i < ids.size(); i++) {
String temp = "id" + i;
paramSource.addValue(temp, ids.get(i));
subQuery = subQuery + "hextoraw(:" + temp + "), ";
}
subQuery = subQuery.substring(0, subQuery.length() - 2);
UPDATE_SUB_STATUS = UPDATE_SUB_STATUS + subQuery + ")";
paramSource.addValue("status", status);
jdbcTempalte.update(UPDATE_SUB_STATUS, paramSource);
}
What this do is create a query with all the ids to hextoraw as id0, id1, id2...... and also added this values in the MapSqlParameterSource instance and then this worked fine and it also used the index for updating my table.
After running my new function the query look like : update
SUBSCRIPTIONS set status = :status, modified_date = systimestamp
where id in (hextoraw(:id0), hextoraw(:id1), hextoraw(:id2)...)
MapSqlParameterSource instance looks like : {("id0", "randomUUID"),
("id1", "randomUUID"), ("id2", "randomUUID").....}
Instead of doing string manipulation, Convert the list to List of ByteArray
List<byte[]> productGuidByteList = stringList.stream().map(item -> GuidHelper.asBytes(item)).collect(Collectors.toList());
parameters.addValue("productGuidSearch", productGuidByteList);
public static byte[] asBytes(UUID uuid) {
ByteBuffer bb = ByteBuffer.wrap(new byte[16]);
bb.putLong(uuid.getMostSignificantBits());
bb.putLong(uuid.getLeastSignificantBits());
return bb.array();
}
