Parameter in like clause JPQL
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 ...
I cannot pass :code = '%value%'
namedQuery.setParameter("%" + this.value + "%");
because in another place I need :value
not wrapped by the %
chars. Any help?
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' .
I don't use named parameters for all queries. For example it is unusual to use named parameters in JpaRepository.
To workaround I use JPQL CONCAT function (this code emulate start with):
@Repository
public interface BranchRepository extends JpaRepository<Branch, String> {
private static final String QUERY = "select b from Branch b"
+ " left join b.filial f"
+ " where f.id = ?1 and b.id like CONCAT(?2, '%')";
@Query(QUERY)
List<Branch> findByFilialAndBranchLike(String filialId, String branchCode);
}
I found this technique in excellent docs: http://openjpa.apache.org/builds/1.0.1/apache-openjpa-1.0.1/docs/manual/jpa_overview_query.html
