Hi there,
if I order a given year in DESCending ORDER, so that the highest
values (of a given variable) for the countries are displayed at the
top of the list, then actually the NULL values appear as first. Only
below, I find the values ordered correctly.
Is there any way to
a) make the countries with NULL values appear at the bottom of
the list
b) neglect the NULL values by still allowing the countries to be
displayed
?
My SQL looks like this:
SELECT
SUM(CASE WHEN year=2002 THEN value ELSE NULL END) AS "y_2002",
SUM(CASE WHEN year=2001 THEN value ELSE NULL END) AS "y_2001",
SUM(CASE WHEN year=2000 THEN value ELSE NULL END) AS "y_2000",
c.name AS name
FROM
aquacult_prod_marine AS d
LEFT JOIN
countries AS c ON c.id = id_country
GROUP BY
name
ORDER BY
y_2000 DESC
Thanks for any info...
Stef
