TypeORM subquery's

Ik hoop dat dit antwoord anderen kan helpen om TypeORM-subquery te gebruiken.

const subquery = await getManager()
    .createQueryBuilder(table4, 't4')
    .select('"t4".f')
    .addSelect('"t4".g')
    .addSelect('"t5".e')
    .addSelect('"t6".h')
    .innerJoin(table5, 't5', '"t4".g = "t5".g')
    .innerJoin(table6, 't6', '"t6".g = "t4".g')
    .where('"t4".k = 4 AND ("t6".i = 2 OR ("t6".i = 1 AND "t6".j = 1))');

  model = await getManager()
    .createQueryBuilder(table1, 't1')
    .select('"t1".a')
    .addSelect("TO_CHAR (MAX (jointable.f), 'MON YYYY')", 'f')
    .addSelect('"t3".c')
    .addSelect('"t3".d')
    .addSelect('"t1".e')
    .leftJoin('table2', 't2', '"t2".e = "t1".e')
    .innerJoin(table3, 't3', '"t3".d = "t2".d')
    .innerJoin('('+subquery.getQuery()+')', 'jointable', '"t1".e = jointable.e')
    .where('jointable.h = :h AND (:d = 3 OR "t3".d = :d)',
      { h: h, d: d })
    .groupBy('"t1".a, "t3".c, "t3".d, "t1".e')
    .orderBy('"t1".a', 'ASC')
    .getRawMany();

Ik gebruikte '('+subquery.getQuery()+')' voor het verkrijgen van de subquery select-query als een equivalent van
