How to specify a JPA named parameter surrounded by

Question

How would I specify a JPA query like:

Query q = 
  em.createQuery(
    "SELECT x FROM org.SomeTable x WHERE x.someString LIKE '%:someSymbol%'"
  );

followed by:

q.setParameter("someSymbol", "someSubstring");

and not triggering a

org.hibernate.QueryParameterException: could not locate named parameter [id]

Much appreciated!

Answer 1

For reference, you could also use CONCAT:

like CONCAT('%', :someSymbol, '%')

Answer 2

query.setParameter(someSymbol, "%" + someSymbol+ "%");

Answer 3

How about

Query q = 
  em.createQuery(
    "SELECT x FROM org.SomeTable x WHERE x.someString LIKE :someSymbol"
);
q.setParameter("someSymbol", "%someSubstring%");

I'm pretty sure I once solved your problem like that.
