I agree. In my opinion the best syntax for outer joins was brought up
by informix. Ex:
SELECT a.f1, b.f1, c.f1
FROM a, OUTER( b, OUTER c )
WHERE a.key = b.fkkey
AND b.key = c.fkkey
Where b is outer from a and c outer from b. Precedence and
hierachical order is given by the parenthesis. Same example
FROM a, OUTER ( b, c)
b and c are outer from a. I find this syntax clear and logic without
any danger of missinterpretation
