Hello list
While browsing old sources by a former employee I realised that he always
did comma seperated joins and then a "where"
FROM
tablea a, tableb b, tablec c
WHERE
a.id=b.id and b.nr=c.nr
whereas I learned to do
FROM
tablea a
LEFT JOIN table b USING (id)
LEFT JOIN table c USING (nr)
Is one of the two ways preferred about the other? I like my way as it is
easier to read and understand but would use anything to gain some speed
in my 5+ hour selects...
bye,
-christian-
