query join issue

I have a query that joins 3 tables, TRAIN_MOD,TRAIN_COMP and TRAINING_COURSE,

There could be many training_course records for each of the other 
tables. I want to get all records from the Train_mod and Train_comp 
table even if there are no training course records available. This is 
the query I'm trying and I get nothing. The data I'm trying this on 
has no training_course records but does have records in the other 
tables. What am I doing wrong.


SELECT *
FROM TRAIN_MOD LEFT OUTER JOIN TRAINING_COURSE ON 
TRAIN_MOD.TRM_SEQ_NO=TRAINING_COURSE.TC_TRM_SEQ
LEFT OUTER JOIN TRAIN_COMP ON TRAIN_MOD.TRM_TRC_SEQ=TRAIN_COMP.TRC_SEQ_NO
where TC_PUB_ED  IS TRUE OR  TC_SEQ_NO IS NULL
