SELECT * FROM gdp WHERE y1970 NOT NULL AND y1971 NOT NULL
AND .... y2005 NOT NULL
It sounds like a bad table design,
because i think you need an field "f_year" and "value_of_f_year" then
there would be entries like
f_year;value_of_f_year
1970 'NULL'
1970 dfgsd
1971 'NULL'
1971 ....
where f_year IS NOT NULL and value_of_f_year IS NOT NULL
My table design is - due to some import/update reasons - surely not
the best one, but pretty simple:
id y1970 y1971 y1972 ......
1 23 25 28
2 NULL NULL 5
3 NULL 94 102
What do you think?

Betreff: [SPAM] [GENERAL] Alias "all fields"?
Hi there,
I guess I am demanding too much.... But it would be cool to have some
kind of alias for "all fields".
What I mean is this here:
Instead of this:
SELECT * FROM gdp WHERE y1970 NOT NULL AND y1971 NOT NULL
AND .... y2005 NOT NULL
I would like to have this:
SELECT * FROM gdp WHERE all-fields NOT NULL
This is, because my tables have different - and a different number of
fields.
In principal, I actually just want to have the number of fields which
are NOT NULL...
Thanks for any advice.
Stef
