How can I write a queryDSL query for the following MySQL query:
SELECT
u.id as user_id,
count(*) as total_completed
date(o.created_at) date
FROM
users u
LEFT JOIN orders o ON o.user_id = u.id
WHERE o.status='COMPLETED'
GROUP BY date(o.created), u.id
I am mainly interested in implementing the date(timestamp_field) so that I can use it for aggregating over entire dates.
This is my OrderEntity:
...
#Table(name = "orders")
public class OrderEntity extends BaseEntity {
#Id
#Column(nullable = false)
private String id;
private Instant createdAt;
...
}
This is in QOrderEntity
public final DateTimePath<java.time.Instant> createdAt = createDateTime("createdAt", java.time.Instant.class);
Basically, how can I truncate/type cast the SQL Timestamp field to DATE in the SELECT query. It needs to be done on the WHERE clause, GROUP BY clause, and SELECT clause
I tried this link here: QueryDSL - select rows with date from timestamp column
You can either use between or a custom expression if you use Querydsl SQL
Something like this
DateExpression<Date> converted = DateTemplate.create(Date.class, "convert(date, {0})",
The API doesn't have create() method, maybe it was removed.
I have the following piece of code:
#Query(value = "select * from james_mail where encode(header_bytes, 'escape') like '%Message-ID: :messageId%'", nativeQuery = true)
List<JamesMail> findByMessageIdFromHeader(#Param(value = "messageId") String messageId);
The expected behavior is to execute the query with bind parameter (e.g. messageID)
Actual behavior is that the query is executed as it is, without biding
What is the solution for actually biding, or there is an workaround for my problem?
Technology stack:
Spring Boot, JPA, Hibernate
here you are trying to encode header_bytes which is contained table james_mail right
and you want to find rows which contains value matching to messageId and contains Message-ID
#Query(value = "select * from james_mail where encode(header_bytes, 'escape') like '%Message-ID%' and encode(header_bytes, 'escape') like %:messageId%", nativeQuery = true)
List<JamesMail> findByMessageIdFromHeader(#Param(value = "messageId") String messageId);
Try to correct your query in this way:
#Query(value = "select * from james_mail where encode(header_bytes, 'escape') like '%Message-ID: ' || :messageId || '%'", nativeQuery = true)
List<JamesMail> findByMessageIdFromHeader(#Param(value = "messageId") String messageId);
I've read the documentation on inserting method parameters into queries and other questions however they all suggest that this should work.
#Query(value = "SELECT * FROM period WHERE time LIKE \":day%\" AND id IN (SELECT id FROM booking)", nativeQuery = true)
List<Booking> findAllBookingsOnDay(#Param("day") String day);
Results in:
Hibernate: SELECT * FROM period WHERE time LIKE ":day%" AND id IN (SELECT id FROM booking)
I've tried removing quotations and percentage but that just results in.
Hibernate: SELECT * FROM period WHERE time LIKE ? AND id IN (SELECT id FROM booking)
The correct way to do this is to just use an unescaped placeholder in the query, and the bind the LIKE wildcard expression to it from the Java side.
#Query(value = "SELECT * FROM period WHERE time LIKE :day AND id IN (SELECT id FROM booking)", nativeQuery =true)
List<Booking> findAllBookingsOnDay(#Param("day") String day);
Usage:
String day = "%friday%"; // or whatever value would make sense here
findAllBookingsOnDay(day);
I want to send parameter from property file in JPQL using #Query
Suppose I have a query,
#Query(value= "Select * from myTable where id = ?1 AND last_modified_date between DATE_SUB(NOW(), INTERVAL ?2) AND NOW()", nativeQuery = true)
List<MyTableClass> getAllData(Long id, String stringSetFromPropertyFile);
Here the "stringSetFromPropertyFile" is sent from the Service class.
When I do the above thing it gives a query error where ?2 as a parameter is not set blank.
try
#Query(value= "Select * from myTable where id = ?1 AND last_modified_date between DATE_SUB(NOW(), INTERVAL ?2) AND NOW()",nativeQuery = true)
List<MyTableClass> getAllData(Long id, String stringSetFromPropertyFile);
I'm using Spring Data JPA, and when I use #Query to to define a query WITHOUT Pageable, it works:
public interface UrnMappingRepository extends JpaRepository<UrnMapping, Long> {
#Query(value = "select * from internal_uddi where urn like %?1% or contact like %?1%",
nativeQuery = true)
List<UrnMapping> fullTextSearch(String text);
}
But if I add the second param Pageable, the #Query will NOT work, and Spring will parse the method's name, then throw the exception No property full found. Is this a bug?
public interface UrnMappingRepository extends JpaRepository<UrnMapping, Long> {
#Query(value = "select * from internal_uddi where urn like %?1% or contact like %?1%",
nativeQuery = true)
Page<UrnMapping> fullTextSearch(String text, Pageable pageable);
}
You can use pagination with a native query. It is documented here: Spring Data JPA - Reference Documentation
"You can however use native queries for pagination by specifying the count query yourself:
Example 59. Declare native count queries for pagination at the query method using #Query"
public interface UserRepository extends JpaRepository<User, Long> {
#Query(value = "SELECT * FROM USERS WHERE LASTNAME = ?1",
countQuery = "SELECT count(*) FROM USERS WHERE LASTNAME = ?1",
nativeQuery = true)
Page<User> findByLastname(String lastname, Pageable pageable);
}
A similar question was asked on the Spring forums, where it was pointed out that to apply pagination, a second subquery must be derived. Because the subquery is referring to the same fields, you need to ensure that your query uses aliases for the entities/tables it refers to. This means that where you wrote:
select * from internal_uddi where urn like
You should instead have:
select * from internal_uddi iu where iu.urn like ...
Considering that the UrnMapping class is mapped to the internal_uddi table, I would suggest this:
#Repository
public interface UrnMappingRepository extends JpaRepository<UrnMapping, Long> {
#Query(value = "select iu from UrnMapping iu where iu.urn like %:text% or iu.contact like %:text%")
Page<UrnMapping> fullTextSearch(#Param("text") String text, Pageable pageable);
}
Please note that you might have to turn off native queries with dynamic requests.
With #Query , we can use pagination as well where you need to pass object of Pageable class at end of JPA method
For example:
Pageable pageableRequest = new PageRequest(page, size, Sort.Direction.DESC, rollNo);
Where,
page = index of page (index start from zero)
size = No. of records
Sort.Direction = Sorting as per rollNo
rollNo = Field in User class
UserRepository repo
repo.findByFirstname("John", pageableRequest);
public interface UserRepository extends JpaRepository<User, Long> {
#Query(value = "SELECT * FROM USER WHERE FIRSTNAME = :firstname)
Page<User> findByLastname(#Param("firstname") String firstname, Pageable pageable);
}
Please reference :Spring Data JPA #Query, if you are using Spring Data JPA version 2.0.4 and later. Sample like below:
#Query(value = "SELECT u FROM User u ORDER BY id")
Page<User> findAllUsersWithPagination(Pageable pageable);
Declare native count queries for pagination at the query method by using #Query
public interface UserRepository extends JpaRepository<User, Long> {
#Query(value = "SELECT * FROM USERS WHERE LASTNAME = ?1",
countQuery = "SELECT count(*) FROM USERS WHERE LASTNAME = ?1",
nativeQuery = true)
Page<User> findByLastname(String lastname, Pageable pageable);
}

Rewrite your query to:
select iu from internal_uddi iu where iu.urn....

I found it works different among different jpa versions, for debug, you'd better add this configurations to show generated sql, it will save your time a lot !
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true
for spring boot 2.1.6.RELEASE, it works good!
Sort sort = new Sort(Sort.Direction.DESC, "column_name");
int pageNumber = 3, pageSize = 5;
Pageable pageable = PageRequest.of(pageNumber - 1, pageSize, sort);
#Query(value = "select * from integrity_score_view " +
"where (?1 is null or data_hour >= ?1 ) " +
"and (?2 is null or data_hour <= ?2 ) " +
"and (?3 is null or ?3 = '' or park_no = ?3 ) " +
"group by park_name, data_hour ",
countQuery = "select count(*) from integrity_score_view " +
"where (?1 is null or data_hour >= ?1 ) " +
"and (?2 is null or data_hour <= ?2 ) " +
"and (?3 is null or ?3 = '' or park_no = ?3 ) " +
"group by park_name, data_hour",
nativeQuery = true
)
Page<IntegrityScoreView> queryParkView(Date from, Date to, String parkNo, Pageable pageable);
you DO NOT write order by and limit, it generates the right sql
I had the same issue - without Pageable method works fine.
When added as method parameter - doesn't work.
After playing with DB console and native query support came up to decision that method works like it should. However, only for upper case letters.
Logic of my application was that all names of entity starts from upper case letters.
Playing a little bit with it. And discover that IgnoreCase at method name do the "magic" and here is working solution:
public interface EmployeeRepository
extends PagingAndSortingRepository<Employee, Integer> {
Page<Employee> findAllByNameIgnoreCaseStartsWith(String name, Pageable pageable);
}
Where entity looks like:
#Data
#Entity
#Table(name = "tblEmployees")
public class Employee {
#Id
#Column(name = "empID")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
#NotEmpty
#Size(min = 2, max = 20)
#Column(name = "empName", length = 25)
private String name;
#Column(name = "empActive")
private Boolean active;
#ManyToOne
#JoinColumn(name = "emp_dpID")
private Department department;
}
When using nativeQuery that is having (nativeQuery = true), you may do the pagination yourself in the query by adding (LIMIT :sizeValue OFFSET :page)
Note:
Your page value passed to this method should be offset * size
Example
#Query(value = "SELECT * FROM person " +
"LIMIT ?1 OFFSET ?2", nativeQuery = true)
Optional<List<TDriverJob>> findPersons(int size, int page);
I tried all above solution and non worked , finally I removed the Sorting from Pagination and it worked
the following tutorial helped me
-> https://www.baeldung.com/spring-data-jpa-query
At this point 4.3. Spring Data JPA Versions Prior to 2.0.4
VERY IMPORTANT to add \ n-- #pageable \ n
Without this I was wrong
Also the pagination setting must be without ordering
PageRequest paginaConf = new PageRequest ((param1 - 1)
, param2);
Finally to convert the Page <Object []>
Page <Object []> list = myQueryofRepo ();
List <XXXModel> lstReturn = myConversor (list.getContent ());
Page <XXXModel> ret = new PageImpl <XXXModel> (lstReturn, pageConf, param2);
This bugged me for a while but I managed with a very smooth solution.
The challenge is JPA did not automatically detect the count query so I resolved to use the countName which according JPA docs Returns the name of the javax.persistence.NamedQuery to be used to execute count queries when pagination is used. Will default to the named query name configured suffixed by .count.
So I created a named query
#NamedNativeQuery(
name = "[queryName].count",
query = [your count query],
resultSetMapping = "[query resultSetMapping name]"
)
}
As indicated, the count query should be suffixed with .count
Count query returns Long so add the resultSetMapping as
#SqlResultSetMapping(
name="[query resultSetMapping name]",
columns={#ColumnResult(name="count", type = Long.class)})
Then in your repository, use the count query as indicated below
#Query(countName ="[queryName].count" , nativeQuery = true)
Page<Object> [mainQuery](...params)
Hope this helps!
