NonUniqueDiscoveredSqlAliasException when two table has same column names

I have two tables `Item` and `Nikasa` - whose definitions looks like: `Item { id, name, spec}` and `Nikasa {id, date, item_id}.` Here `item_id` represents `Item.id`. I did a simple native SQL join to select only `Item.id` and `Nikasa.id` as: ``` Session s = getSession(); SQLQuery sq = s.createSQLQuery("SELECT it.id, nik.id FROM item it LEFT JOIN nikasa nik ON (it.id = nik.item_id)"); List result = sq.list(); ``` But I am getting exception `NonUniqueDiscoveredSqlAliasException : Encountered a duplicated sql alias [ID] during auto-discovery of a native-sql query` at line `List result=sq.list();`: Stack-trace : ``` org.hibernate.loader.custom.NonUniqueDiscoveredSqlAliasException: Encountered a duplicated sql alias [ID] during auto-discovery of a native-sql query at org.hibernate.loader.custom.CustomLoader.autoDiscoverTypes(CustomLoader.java:594) at org.hibernate.loader.Loader.getResultSet(Loader.java:1986) at org.hibernate.loader.Loader.doQuery(Loader.java:829) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:289) at org.hibernate.loader.Loader.doList(Loader.java:2463) at org.hibernate.loader.Loader.doList(Loader.java:2449) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2279) at org.hibernate.loader.Loader.list(Loader.java:2274) at org.hibernate.loader.custom.CustomLoader.list(CustomLoader.java:331) at org.hibernate.internal.SessionImpl.listCustomQuery(SessionImpl.java:1585) at org.hibernate.internal.AbstractSessionImpl.list(AbstractSessionImpl.java:224) at org.hibernate.internal.SQLQueryImpl.list(SQLQueryImpl.java:156) ``` Can you please suggest what's wrong going on?
