How to use LIKE in hibernate detached criteria for integer data type?

Question

I have to do Restrictions.like("sequenceNo", "%" + Integer.valueOf(sequenceNo.trim()) + "%").

The field sequenceNo is integer type but the sequenceNo param value is string. My problem is I get an exception java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer. For some reasons I really have to make my param a string data type. When I tried it in SQL to LIKE an integer it works.

Please help. Thanks.

You cannot add Criteria`s property restrictions for the purpose, as during fetching, property value specifiedwould be casted according to the 'field type' specified in Entity class.

However, a solution would be using SQLRestriction of criteria, to by pass casting. I have tested and this works.

yourDetachedCriteriaObj.add(Restrictions.sqlRestriction(" sequenceNo LIKE '%"+yourSequenceNumToSearch+"%' "));

To get list you would do like below

List ls = yourDetachedCriteriaObj.getExecutableCriteria(yourSession).list();
// iterate over list or do whatever.
