Is it possible to put one left outer join within other left outer join

Question

Can I put a left outer join inside another left outer join? Like this:

SELECT * FROM table1 
LEFT OUTER JOIN table2 ON (LEFT OUTER JOIN table 3 ON (Join Conditions))
WHERE
....(where conditions)

Answer 1

To group multiple joins, the syntax is as follows (untested on db2)

SELECT *
FROM table1 t1
LEFT JOIN (
  table2 t2 INNER JOIN table3 t3 ON t3.someId = t2.someId
) ON t2.someId = t1.someId

Same syntax for left join inside LEFT JOIN(), but please read comment by @X-Zero

SELECT *
FROM table1 t1
LEFT JOIN (
  table2 t2 LEFT JOIN table3 t3 ON t3.someId = t2.someId
) ON t2.someId = t1.someId
