Test code:
public void test() {
CriteriaQuery<ColumnImpl> cri = cb.createQuery(ColumnImpl.class);
Root<VirtualTableImpl> tbl = cri.from(VirtualTableImpl.class);
Join<VirtualTableImpl, ColumnImpl> col = tbl.join("columns");
Join<ColumnImpl, ColumnFormatImpl> format = col.join("formats", JoinType.LEFT);
cri.where(cb.equal(format.get("formatName"), "ABC"));
cri.select(col);
em.createQuery(cri).getResultList();
}
Generated SQL:
SELECT t1.id, t1.PARENT_ID
FROM VirtualTableImpl t0 INNER JOIN ColumnImpl t1 ON t0.id = t1.PARENT_ID INNER
JOIN ColumnFormatImpl t2 ON t1.id = t2.PARENT_ID
WHERE (t2.formatName = ? AND 1 = 1)
As you can see the secong JOIN is INNER instead of LEFT OUTER
