Pregunta HSQLDB Ordenar por con múltiples columnas


Estoy realizando una consulta utilizando hsqldb e hibernar. Tengo un pedido por declaración: -

Query query = em
    .createQuery("SELECT DISTINCT new com.mytransferobject.QuickSearchResultTO(m.id, m.firstName||' '||m.surname, '')  " +
        "FROM Member m, ClassC c, ClassCm cm " +
        "WHERE  c.id = cm.clubId AND m.id = cm.memberId " +
        "AND c.lft >= :lft AND c.lft <= :rgt " +
        "AND (firstName LIKE :memberName OR surname LIKE :memberName) " +
        "AND m.deleted = false " +
        "AND c.deleted = false " +
        "ORDER BY m.firstName, m.surname");

query.setParameter("lft", lft);
query.setParameter("rgt", rgt);
query.setParameter("memberName", memberName + "%");

Esto funciona bien en MYSQL, pero falla en mi código de prueba (usando hsqldb 2.2.6). Intenté concatenarlos juntos y funciona bien, pero esta es una consulta muy utilizada, así que me gustaría evitar operaciones innecesarias.

Estoy recibiendo una excepción: -

Probablemente, tiene una excepción "orden inválida por expresión" porque especifica una columna en ORDER BY (en su caso, m.firstName y m.surname) que no están explícitamente en la cláusula SELECT. Algunas bases de datos, como SQL Server y MySQL no necesitan esto, pero otras como HSQLDB y DB2 no pueden hacer esto ORDENADO sin los campos en SELECT también.

Creo que tu código funcionará si usas:

Query query = em
    .createQuery("SELECT DISTINCT new com.mytransferobject.QuickSearchResultTO(m.id, m.firstName, m.surname, m.firstName||' '||m.surname, '')  " +
        "FROM Member m, ClassC c, ClassCm cm " +
        "WHERE  c.id = cm.clubId AND m.id = cm.memberId " +
        "AND c.lft >= :lft AND c.lft <= :rgt " +
        "AND (firstName LIKE :memberName OR surname LIKE :memberName) " +
        "AND m.deleted = false " +
        "AND c.deleted = false " +
        "ORDER BY m.firstName, m.surname");

Tuve el mismo problema, lo solucioné utilizando GROUP BY en lugar de DISTINCT, devolvía el mismo resultado. Tu código funcionará si usas:

Query query = em
.createQuery("SELECT new com.mytransferobject.QuickSearchResultTO(m.id, m.firstName||' '||m.surname, '')  " +
    "FROM Member m, ClassC c, ClassCm cm " +
    "WHERE  c.id = cm.clubId AND m.id = cm.memberId " +
    "AND c.lft >= :lft AND c.lft <= :rgt " +
    "AND (firstName LIKE :memberName OR surname LIKE :memberName) " +
    "AND m.deleted = false " +
    "AND c.deleted = false " +
    "GROUP BY m.idORDER BY m.firstName, m.surname");
