问题 In JPA, when executing a native query, I have to escape backslash characters to double backslash. E.g. when having a where clause like UPPER(app.NAME) like UPPER(?) escape '\' then I need to create a string which contains: UPPER(app.NAME) like UPPER(?) escape '\\' Then I run a native query using openJPA 2.2.2: final EntityManager entityManager = EntityManagerFinder.getEntityManager(); final Query query = entityManager.createNativeQuery(sql, Response.class); The SQL statement is read from XML

问题 I have i query statement like this: select t.* from T_ex_table t where regexp_like(t.note, '^(.*[^[:digit:]]+)?([condition])([^[:digit:]]+.*)?$', 'n') And if I use it in jpa with querydsl(com.querydsl) like(this is scala, and it doesn't important): @Query(value = "select t.*" + " from T_PURCHASE t" + " where regexp_like(t.note," + " '^(.*[^[:digit:]]+)?([?1])([^[:digit:]]+.*)?$'," + " 'n')", nativeQuery = true) def getByTrackingNo(trackingNo: String): Purchase While i debug test, it always

问题 I'm trying to implement Interface-based Projection but I cannot make it work with my custom type column. Below example of what I'm trying to do: Repository: @Query(value = "SELECT customType from TABLE", nativeQuery = true) List<TestClass> getResults(); Interface projection: public interface TestClass { @Convert(converter = MyCustomTypeConverter.class) MyCustomType getCustomType(); } Converter: @Converter public class MyCustomTypeConverter implements AttributeConverter<MyCustomType, String> {
