Dear dude, I have used (+) symbol for outer join, but in this project HiRDB doesn't work with (+). So I have to use 'left outer join' terms, I am however not used to it.
Here is my question: Can I use the table which is the object of 'left outer join' with another join? for example, it is cTable.
select aTable.name, bTable.address, cTable.yearlyPay from aTable left outer join cTable on aTable.company = cTable.company, bTable where bTable.position = cTable.position and aTable.workyear = bTable.workyear;
in this example above, cTable is left outer joined with aTable and used to join with bTable in where phrase. I am afraid if we can't join cTable with another table(bTable) once cTable is used to left outer join with aTable.

If you are using pure SQL, this syntax is definitely ok. If you are using HQL or something similar, it should also be ok. Why don't you just try it ;) ?
