Parameter in like clause JPQL

Question

I am trying to write a JPQL query with a like clause:

LIKE \'%:code%\'

I would like to have code=4 and find

455
554
646
...
         


        

Answer 1

If you do

LIKE :code

and then do

namedQuery.setParameter("code", "%" + this.value + "%");

Then value remains free from the '%' sign. If you need to use it somewhere else in the same query simply use another parameter name other than 'code' .
