[SOLVED] Using LIKE % in Hibernate

Using LIKE % in Hibernate

How do I use LIKE % in Hibernate. I want to use a SQL with LIKE % in my hbm.xml file. I have 2 queries which I am consolidating to 1.

The query looks like this:

select * from PAY_GROUP_VW where CASE_SID=? AND CASE_TLE like %?%

I also tried %?%. I have used like clause without % and it works. But % does not work.

Wrapped exception:

org.springframework.dao.InvalidDataAccessResourceUsageException: could not execute query; nested exception is org.hibernate.exception.SQLGrammarException: could not execute query
    at org.springframework.orm.hibernate3.SessionFactoryUtils.convertHibernateAccessException(SessionFactoryUtils.java:630)
    at org.springframework.orm.hibernate3.HibernateAccessor.convertHibernateAccessException(HibernateAccessor.java:412)
    at org.springframework.orm.hibernate3.HibernateTemplate.doExecute(HibernateTemplate.java:424)
    at org.springframework.orm.hibernate3.HibernateTemplate.executeFind(HibernateTemplate.java:343)

This is how I pass the parameters:

q.setParameter(0, csId);
q.setParameter(1, csTle);
return q.list();

Tried like % || ? and got the following exception:

org.springframework.dao.InvalidDataAccessResourceUsageException: could not execute query; nested exception is org.hibernate.exception.SQLGrammarException: could not execute query
    at org.springframework.orm.hibernate3.SessionFactoryUtils.convertHibernateAccessException(SessionFactoryUtils.java:630)

Solution

Maybe the user_id is not a char/varchar? You have to convert the user_id with str() to character data first!

Example:

SELECT *
FROM abc.def_vw a
WHERE user_id = ?
AND str(user_id) LIKE '%' || ?
