How to specify a JPA named parameter surrounded by wildcards?

Question

How would I specify a JPA query like:

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


        

Answer 1

For reference, you could also use CONCAT:

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

Answer 2

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.

Answer 3

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