Case Insensitive search in hibernate

Question

I want to perform a hibernate named query but its giving hibernate syntax exception. In SQL it's running properly..chart will come as a query parameter and query value = 'chart' ?

SELECT * FROM faq WHERE UPPER(answer) LIKE UPPER('%chart%')

select f from Faq f where lower(f.question) like lower('%:query%') or lower(f.answer) like lower('%:query%')

@NamedQuery(name = "findQuesAnsByQuery", query = "select f from Faq f where lower(f.question) like lower('%:query%') or lower(f.answer) like lower('%:query%')")

Trace:

[0] = {java.lang.StackTraceElement@16677}"org.springframework.orm.hibernate3.SessionFactoryUtils.convertHibernateAccessException(SessionFactoryUtils.java:679)"
[1] = {java.lang.StackTraceElement@16678}"org.springframework.orm.hibernate3.HibernateAccessor.convertHibernateAccessException(HibernateAccessor.java:412)"

I think your problem is in using the '%:query%'.. in the query.. Change to this:

@NamedQuery(name = "findQuesAnsByQuery"
  , query = "select f from Faq f 
        where lower(f.question) like lower(CONCAT('%', :query, '%')) 
           or lower(f.answer) like lower(CONCAT('%', :query, '%'))")

or

@NamedQuery(name = "findQuesAnsByQuery"
      , query = "select f from Faq f 
            where lower(f.question) like lower(:query) 
               or lower(f.answer) like lower(:query)")

and then set the param:

.setString("query", "%" + query+ "%")
