I try to get orders of user by query :
#Query(value = "SELECT * FROM ORDERS WHERE USER_ID = ?1 AND CAST(CREATE_AT AS NVARCHAR(100)) LIKE ?2 OR CAST(GRAND_TOTAL AS NVARCHAR(100)) LIKE ?2 OR CAST(STATUS AS NVARCHAR(100)) LIKE ?2" , nativeQuery = true)
Page<Order> getOrdersByUserSearch(int userID, String searchS, Pageable pageable);
But it always return empty list. i run this code in SQL server and it work (?1 =2. ?2 = '2021-06-26').
If I try to change "NOT LIKE" instead of "LIKE" It run.
I dont want using query ( not native), Named query or specification method because it get more error.
Any advice?.
SQL like query requires % along with the value for a match. In case of ordered parameters in queries we can use:
#Query("SELECT m FROM Movie m WHERE m.rating LIKE ?1%")
List<Movie> searchByRatingStartsWith(String rating);
Click here for more info.
In your case the query string should be like this:
SELECT * FROM ORDERS WHERE USER_ID = ?1 AND CAST(CREATE_AT AS NVARCHAR(100)) LIKE %?2% OR CAST(GRAND_TOTAL AS NVARCHAR(100)) LIKE %?2% OR CAST(STATUS AS NVARCHAR(100)) LIKE %?2%

Since limit is not supported in #query of spring, we need alternative way for this other than pagination query param
#Query(" select something so where so.id>50 order by so.created desc")
#QueryHints(#QueryHint(name = "org.hibernate.annotations.FETCH_SIZE" , value = "1"))
optionam<something> findlatestSomething();
#Query(" select something s where s.id = select max(so.id) something so order by so.id desc")
optionam<something> findlatestSomething();
this is my native SELECT Query in Repository
#Modifying
#Query(value = "SELECT * FROM tasks WHERE title LIKE '%Java%' ORDER BY id DESC ", nativeQuery = true)
List<Task> listAllTasks();
this works ok, but when I use custom column name instead of *, like this
#Modifying
#Query(value = "SELECT title FROM tasks WHERE title LIKE '%Java%' ORDER BY id DESC ", nativeQuery = true)
List<Task> listAllTasks();
I have this error :
org.postgresql.util.PSQLException: The column name id was not found in this ResultSet.
any Help?
The resultset doesn't have the "id" in it, you have to provide it.
You should change the way you are declaring your SQL:
SELECT t.title, t.id FROM tasks t WHERE t.title LIKE '%Java%' ORDER BY t.id DESC
Check out this sort example:Native Queries
Select * from Entity -> returns a List of Entity
Example:
#Query(select * from tasks)
List<Task> findAllTasks();
Select column from Entity -> returns a List of Types of the entity.
Example:
#Query(select t.title from tasks t)
List<String> findTitle_AllTasks();
title is of the type String
Select multiple columns from Entity -> returns an Object[] holding the data
Example:
#Query(select t.id, t.title from tasks t)
List<Object[]> findIdTitle_AllTasks();
So, you are retrieving String type data - title and asking to return a List of Task type. This is causing the problem. You can actually check the hibernate docs under HQL and JPQL to understand this.
Plus, you are doing a SELECT (DQL operation). #Modifying is rudimentary here as it is used for DML operations using Data JPA - UPDATE/DELETE.
I have a search form containing 4 dropdown lists
and I want to create an HQL Query that search for the object list depending on the values selected in those dropdown lists
I hope that I was clear ><
like :
private static final String QUERY_SEARCH_USERS = "SELECT u FROM User where param = ... ";
or I don't know how it should be ^^'
Is it possible ?
The correct HQL/JPQL query:
SELECT u FROM User u
WHERE u.id IS NULL OR u.id = :param1 AND u.name IS NULL OR u.name = :param2
I have the following named query
#NamedQuery(name = "UserFlight.getUserFlightDetails",
query = "SELECT new com.foobar.UserFlightDetails(uf.flight.divertedAirport, uf.flight.number) " +
"FROM UserFlight uf WHERE uf.user.id=?1 AND uf.flight.id=?2")
The UserFlightDetails constructor is as follows
public UserFlightDetails(Airport airport, String flightNumber) {
this.setDivertedAirport(airport);
this.setFlightNumber(flightNumber);
}
divertedAirport is a foreign key in the flight table, path=(uf.flight.divertedAirport)
My problem is when divertedAirport is null (it's a nullable foreign key), my HQL query returns null as the result (The code doesn't even trigger the constructor above), so I don't get the flightNumber which is never null.
If the divertedAirport isn't null, I get both the airport and the flight number fine (and the above constructor gets executed just fine).
What could be causing this and how could I resolve it? I tried some null functions like nullif and coalesce but nothing helped.
I'm using spring boot 1.2.7, hibernate-core 4.3.11.Final
Probably, the problem is the uf.flight.divertedAirport. This expression do a JOIN between flight and divertedAirport but, as you say, divertedAirport is a fk and can be null.
So, you need to use the LEFT JOIN.
I would rewrite your query like this:
#NamedQuery(name = "UserFlight.getUserFlightDetails",
query =
"SELECT new com.foobar.UserFlightDetails(divertedAirport, flight.number)
FROM UserFlight uf
JOIN uf.flight flight
LEFT JOIN flight.divertedAirport divertedAirport
JOIN uf.user user
WHERE user.id = ?1 AND flight.id = ?2 ")
I remove the references like uf.user.id for a explicit JOIN (JOIN uf.user user plus user.id), because is more legible and this kind of problem that generated your question is more easy to find using this way to write JPQL queries.
Query:
select *
from easquestionsinfo
where questionname in(select questionname
from easresponseinfo
where isconflict = 'yes')
This query works fine and returns me the records from table 'easquestioninfo' when questionname is equal to the one returned by the inner query which returns set of questionname where isconflict='yes'.
JPA supports JPQL, SQL, and Criteria.
You can execute this SQL directly using createNativeQuery().
For JPQL, it depends on your object model, perhaps something like,
Select q fom QuestionInfo q where q.name in (Select r.name from ResponseInfo q2 where r.isConflict = 'yes')
