How to write a transitive sql join in DB2?

Question

I want something like the following.

SELECT fewCols, aColFromNewTbl FROM TABLE_A AS A 
LEFT OUTER JOIN TABLE_B AS B ON A.ID = B.ID
LEFT OUTER JOIN TABLE_C AS C ON A.ID = C.ID
INNER JOIN A_NEW_TABLE AS NEWTBL ON NEWTBL.ID = B.ID;

Somehow I'm not able to achieve this functionality. Actually above query is suppose to join A with NEWTBL , but I'm joining it with B , which is already joined with A . For my results I want them to come exclusively from the join of NEWTBL and B . I don't know how I can get desired results?

Probably you need this:

SELECT fewCols, aColFromNewTbl
FROM TABLE_A AS A 
LEFT OUTER JOIN TABLE_B AS B
    INNER JOIN A_NEW_TABLE AS NEWTBL
    ON NEWTBL.ID = B.ID
ON A.ID = B.ID
LEFT OUTER JOIN TABLE_C AS C
ON A.ID = C.ID;
