Getting multiple variables in URL for JSON - mysql

Question

I am trying to retrieve multiple variables in the URL, so I could send a query to database to select a specific object, but it seems that it picks up the first object and others are null.
#RequestMapping(value = "getGroup/{Name}/{StartDate}/{EndDate}/{Status_GroupID}", method = RequestMethod.GET)
public #ResponseBody List<GroupsDetails> getGroupList(
#PathVariable String Name, String StartDate, String EndDate,
Integer Status_GroupID) {
return musicStoreService.getGroupList(Name, StartDate, EndDate, Status_GroupID);
}
The error I am recieving:
Hibernate: select groupsdeta0_.Status_GroupID as Status1_1_, groupsdeta0_.GroupsID as GroupsID1_, groupsdeta0_.EndDate as EndDate1_, groupsdeta0_.Name as Name1_, groupsdeta0_.StartDate as StartDate1_ from Groups groupsdeta0_ where groupsdeta0_.Name=Gamma and (groupsdeta0_.StartDate is null) and (groupsdeta0_.EndDate is null) and (groupsdeta0_.Status_GroupID is null)

SEVERE: Servlet.service() for servlet [SpringDispatcher] in context with path [/ATS] threw exception [Request processing failed; nested exception is org.hibernate.exception.SQLGrammarException: could not execute query] with root cause
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'Gamma' in 'where clause'
The table is named Groups and it has rows : Name, StartDate, EndDate, Status_GroupID and GroupsID
Update:
I am trying to retrieve a primarykey by giving the rows details, but it is not working.
#Override
public List<GroupsDetails> getGroupList(String Name, String StartDate, String EndDate, Integer Status_GroupID) {
SessionFactory sessionFactory=HibernateSessionManager.getSessionFactory();
Session session=sessionFactory.getCurrentSession();
Transaction transaction=session.beginTransaction();
try{
transaction.begin();
#SuppressWarnings("unchecked")
List<GroupsDetails> groupList=session.createSQLQuery("FROM Groups WHERE Name=" + Name + " AND StartDate=" + StartDate + " AND EndDate=" + EndDate + " AND Status_GroupID=" + Status_GroupID).list();
return groupList;
}finally{
session.close();
}
}
But it throws the exception that is badly syntax, even tho I can not see the error in syntax.
The error is :
Hibernate: FROM Groups WHERE Name=Gamma AND StartDate=01-06-2014 AND EndDate=01-09-2014 AND Status_GroupID=1

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM Groups WHERE Name=Gamma AND StartDate=01-06-2014 AND EndDate=01-09-2014 AND' at line 1

Answer 1

As per the error details :
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version for the right syntax to use near
'FROM Groups WHERE Name=Gamma AND StartDate=01-06-2014 AND EndDate=01-09-2014 AND' at line 1
it clearly shows that you are missing quotes, eg: Name=Gamma should be Name='Gamma'
Alternatively you can create the Query by using Parameters for example:
query = sess.createSQLQuery("SELECT * FROM Groups
WHERE NAME=:name AND StartDate=:startDate AND EndDate=:endDate
AND Status_GroupID=:status_GroupID").addEntity(Groups.class);
query.setString("name", name);
query.setDate("startDate", StartDate);
query.setString("endDate", EndDate);
query.setString("status_GroupID", Status_GroupID);
List<GroupsDetails> groupList = query.list();

Answer 2

You need to have #PathVariable infront of all parameters. Like
public #ResponseBody List<GroupsDetails> getGroupList(
#PathVariable String Name, #PathVariable String StartDate, #PathVariable String EndDate,
#PathVariable Integer Status_GroupID)
