Hello I'm trying to read tables related with ManyToOne , i get the result when i execute the query in Navicat :
but when i try to display data in the front with angular i failed i get only the main tables
this is the query :
//like this
#Query(value = "SELECT\n" +
"\tnotification.idnotif,\n" +
"\tnotification.message,\n" +
"\tnotification.\"state\",\n" +
"\tnotification.title,\n" +
"\tnotification.\"customData\",\n" +

"\thospital.\"siretNumber\",\n" +
"\tusers.firstname,\n" +
"\tusers.\"isActive\" \n" +
"FROM\n" +
"\tnotification\n" +
"\tINNER JOIN hospital ON notification.receiver = :reciver\n" +
"\tINNER JOIN users ON notification.sender = :sender",nativeQuery = true)
List<Notification> findNotificationCustomQuery(#Param("reciver") Long reciver,#Param("sender") Long sender);
please what can i do to resolve this problem !

You are doing inner join in the native query. Follow as below. Change the return type to Object[] from Notification.
#Query(value = "SELECT\n" +
"\tnotification.idnotif,\n" +
"\tnotification.message,\n" +
"\tnotification.\"state\",\n" +
"\tnotification.title,\n" +
"\tnotification.\"customData\",\n" +
"\tnotification.\"date\",\n" +
"\tnotification.receiver,\n" +
"\tnotification.sender,\n" +
"\tnotification.\"type\",\n" +
"\thospital.\"name\",\n" +
"\thospital.\"siretNumber\",\n" +
"\tusers.firstname,\n" +
"\tusers.\"isActive\" \n" +
"FROM\n" +
"\tnotification\n" +
"\tINNER JOIN hospital ON notification.receiver = :reciver\n" +
"\tINNER JOIN users ON notification.sender =
:sender",nativeQuery = true)
List<Object []> findNotificationCustomQuery(#Param("reciver")
Long reciver,#Param("sender") Long sender);
Then you have to loop the result as below and get the attributes.
for(Object[] obj : result){
String is = obj[0];
//Get like above
}
