                                                                        "a.eventId = b.eventId AND" +
                                                                        "a.nameTransferId = b.nameTransferId AND" +
                                                                        "a.boRowNo = b.boRowNo AND" +
                                                                        "RANK = '1')";

Please have a glance and suggest me if any wrong syntax

Answer 1

The (first) error is actually in the message...

Error: Caused by:  org.hibernate.queryexception: **in** expected  [hql query]

An IN is expected.

I don't really understand your join. Your JOIN on the second subselect, is that supposed to be where IN?
