I am using Spring Data JPA with postgresql as data base.Want to search a pattern using user given keyword
#Query(value = "SELCET * FROM table_name WHERE column_name LIKE (CONCAT('%',:pattern,'%'))")
List<Class> findPattern(String pattern);
but :pattern is not replacing with pattern value
You may try binding the entire LIKE expression to a single placeholder:
#Query(value = "SELECT * FROM table_name WHERE column_name LIKE :pattern")
List<Object[]> findPattern(String pattern);
The usage would be something like this:
String value = "blah";
String pattern = "%" + value + "%";
List<Object[]> rs = repo.findPattern(pattern);
Since like %pattern% is the same as contains pattern, your use case doesn't even need a query coded:
List<MyClass> findByColumnNameContaining(String pattern);
i created domain in postgres:
create domain arrayofids as numeric[];
Now i want to use the domain in spring data like this:
String fakeQuery = "unnest(CAST (:ids AS arrayofids))";
Query nativeQuery = entityManager.createNativeQuery(fakeQuery);
BigInteger[] arrayOfids = new BigInteger[] {new BigInteger("1"),new BigInteger("2)} //or It can be List. It is not important
nativeQuery.setParameter("ids", arrayOfids);
List resultList = nativeQuery.getResultList();
Of course i get Error:
org.postgresql.util.PSQLException: ERROR: cannot cast type bytea to arrayofIds
Before i used https://dalesbred.org/docs/api/org/dalesbred/datatype/SqlArray.html and it worked fine or did custom types in JDBC myself. Hibernate doesn't allow use my domain easy.
Query like that:
select * from mtTbale where id in :ids
is not interested. I should use the domain with unnest and CAST
Make :ids as a text representation of an array of numbers, i.e. "{1, 2}" and add SELECT to the query.
Try this:
String fakeQuery = "SELECT unnest(CAST (:ids AS arrayofids))";
Query nativeQuery = entityManager.createNativeQuery(fakeQuery);
String arrayOfids = "{" + 1 + ", " + 2 + "}"; // obtain the string as is relevant in your case
nativeQuery.setParameter("ids", arrayOfids);
List resultList = nativeQuery.getResultList();
and the second query should look like this:
select * from mtTbale where id = ANY(CAST(:ids AS arrayofids));
You may also use Postgres shorthand (and more readable) cast syntax.
Instead of CAST(:ids AS arrayofids) use :ids::arrayofids.
I have a table with a JSONB column. In my project I am using Spring JPA and to query that column I want to use nativeQuery. My problem is to inject varibale into the query like below:
#Query(nativeQuery = true, value = "SELECT * FROM items WHERE item_json -> 'attributes' #> '{\"Param1\": \"" + :param + "\"}' ")
List<Items> findByParameter(#Param("param") String param);
The above query does not work as param is not considered as JPA parameter. I am wondering if anyone knows how to do this? or I should do it in another way?
Using spring data JPA, I am trying to make this sort of query (it is more complex, this is a simple case)
#Query(nativeQuery = true,
value = "SELECT * FROM events WHERE typeId IN (?1)")
List<Event> findEventsByType(List<Integer> types);
When I launch the query, an exception raises:
org.postgresql.util.PSQLException: Can't infer the SQL type to use for an instance of java.util.ArrayList. Use setObject() with an explicit Types value to specify the type to use.
I have tried List < Integer >, Integer[], Object[] and String but it is not working...
Can't I pass list of values?
Which is the best approach to make this sort of queries?
Thanks!
Try taking away the #Query and make the method name:
public List<Event> findByTypeIn(List<Integer> types);
See table 2.2 in the link: http://docs.spring.io/spring-data/jpa/docs/1.2.0.RELEASE/reference/html/
I tried like below and it works for me.
#Query(value = "select * from events where type_id in :types", nativeQuery = true)
List<Event> findEventsByType(#Param("types") List<Integer> types);
#Query(value = "SELECT c from Company c where " +
"c.companyName IN (:company_names)")
List<Company> findCompaniesByName(#Param("company_names") List<String> companyNames);
This is the solution to your problem.
Here I am passing List which contains company names and I am querying DB and storing result in List.
Hope this hepls!
Use JPQL. A native query is or should be passed to the database exactly as you have created the SQL string, and unless your driver can take a serialized collection and understand that the single parameter needs to be interpreted as many, it just won't work. The collection you pass in needs the SQL expanded from (?) to (?, ?,...) based on the number of elements in a collection, and JDBC drivers just are not able to do this, and JPA providers are required to execute the string as is.
A JPQL query allows the JPA provider to create the SQL it needs dynamically based on the list passed in, so it can expand the collection for you.
Try this. It will work for Native Query in SpringBoot JPA:
#Query(value = "SELECT * FROM table WHERE columnName IN (:inputList)" ,
nativeQuery = true)
List<Object> findByObjectList(#Param("inputList") List<Object> inputList);
And also in case of JPA, try the below :
List<Object> findByObjectList(List<Object> inputList)
I know this is a little bit out of context (we use Update and not Select), but this can be usefull for others :
/**
* Update the state of list of entities using their ids
* #param ids request ids
* #param state new state
* #return
*/
#Modifying
#Query(value = "UPDATE AbstractRequest SET state = :state WHERE id IN (:ids)")
int updateStates(#Param("ids") List<Long> ids, #Param("state") InternalRequestStep state);
pass array this way inside IN Clause
#Query(value = "select name from teams where name in :names", nativeQuery = true)
List<String> getNames(#Param("names") String[] names);
Call this way
String[] names = {"testing team","development team"};
List<String> teamtest = teamRepository.getNames(names);
Remove brackets around (?1) parameter. Your query value should look like that:
#Query(value = "SELECT * FROM events WHERE typeId IN ?1")
try querying like this:
#Query(nativeQuery = true,
value = "SELECT * FROM events WHERE typeId = ?1")
List<Event> findEventsByType(List<Integer> types);
did it work?
This relates to taking data from a Google Fusion table.
When I first set up my site, GF tableid was a numeric value, (var tableid = 123456;) and I built a query like this:
layer.setQuery("SELECT 'Latitude' FROM " + tableid + " WHERE 'Name' contains etc etc
Now tableid is something like var tableid = '12DFty24'; and I'm having trouble converting the setQuery to handle it.
I've tried adding an extra single quote around tableid, but that doesn't work. Nor do backslashes.
Ideas would be gratefully received!

You are using the old syntax that can't work with encrypted ID, numeric ID's are deprecated.
You have to change your code using the new syntax; here is the documentation
Example:
new google.maps.FusionTablesLayer({ query: {[FusionTablesQuery object]}});
And here's the one that works...need to be careful with parentheses and commas!
function searchAddress()
{
var searchString = document.getElementById('searchAddressString').value.replace("'", "\\'");
// layer.setQuery("SELECT 'Latitude' FROM " + tableid + " WHERE 'Address' contains ignoring case '" + searchString + "'");
var layer = new google.maps.FusionTablesLayer({
query: {
select: 'Latitude',
from: tableid,
where: 'Address' contains ignoring case '" + searchString + "'"
}
});
layer.setMap(map);
}
