How to insert into db in spring-data? - spring

Question

I want to make a request that inserts data into my database. The table has 4 columns: ID_DOCUMENT (PK), ID_TASK, DESCRIPTION, FILEPATH
Entity
...
#Column(name = "ID_TASK")
private Long idTask;
#Column(name = "DESCRIPTION")
private String description;
#Column(name = "FILEPATH")
private String filepath;
...
Repository
#Modifying
#Query("insert into TaskDocumentEntity c (c.idTask, c.description, c.filepath) values (:id,:description,:filepath)")
public void insertDocumentByTaskId(#Param("id") Long id,#Param("description") String description,#Param("filepath") String filepath);
Controller
#RequestMapping(value = "/services/tasks/addDocument", method = RequestMethod.POST)
#ResponseBody
public void set(#RequestParam("idTask") Long idTask,#RequestParam("description") String description,#RequestParam("filepath") String filepath){
//TaskDocumentEntity document = new TaskDocumentEntity();
taskDocumentRepository.insertDocumentByTaskId(idTask,descriere,filepath);
}
When I run my test, I get this error:
Caused by: org.hibernate.hql.ast.QuerySyntaxException: expecting OPEN, found 'c' near line 1, column 32 [insert into TaskDocumentEntity c (c.idTask, c.descriere, c.filepath) values (:id,:descriere,:filepath)]
I tried to remove the alias c, and still doesn`t work.

Spring data provides out of the box save method used for insertion to database - no need to use #Query. Take a look at core concepts of springData (http://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.core-concepts)
thus in your controller just create object TaskDocumentEntity and pass it to repository
#RequestMapping(value = "/services/tasks/addDocument", method = RequestMethod.POST)
#ResponseBody
public void set(#RequestParam("idTask") Long idTask,#RequestParam("description") String description,#RequestParam("filepath") String filepath){
// assign parameters to taskDocumentEntity by constructor args or setters
TaskDocumentEntity document = new TaskDocumentEntity(idTask,descriere,filepath);
taskDocumentRepository.save(document);
}

There is a way to do this but it depends on the db you're using. Below worked for me in Oracle (using Dual table):
#Repository
public interface DualRepository extends JpaRepository<Dual,Long> {
#Modifying
#Query("insert into Person (id,name,age) select :id,:name,:age from Dual")
public int modifyingQueryInsertPerson(#Param("id")Long id, #Param("name")String name, #Param("age")Integer age);
}
So in your case, it would be (if Oracle):
#Modifying
#Query("insert into TaskDocumentEntity (idTask,description,filepath) select :idTask,:description,:filepath from Dual")
public void insertDocumentByTaskId(#Param("idTask") Long id,#Param("description") String description,#Param("filepath") String filepath)
I'm not sure which db you're using, here's a link which shows at the bottom which db's support select stmts without a from clause : http://modern-sql.com/use-case/select-without-from
