I have tried and am unable so far to get this out of my database.
Any suggestions?
SELECT count( publications.title) AS title_number,
publications.year,
publications.affiliation=20 FROM publications GROUP BY
affiliation, year
ORDER BY year;
There is some for loop I am not getting, and am also not
getting the
= zero counts with the count(*).
You won't be able to get an sql query to return in that
format (I know
what you're trying to do, I've used the same chart software).
You won't get zero counts for data that doesn't exist, you'll need to
generate your series before hand:
?php
for ($i = 2000; $i 2006; $i++) {
$data[$i] = 0;
}
?
then later on override that value.
Thanks - but it's a dynamic dataset and I didn't want to hard code dates in.
I managed to do it by first doing a query on the years, then doing a count
query based on the year from the query above, and if no year was avaiable
count was 0.
Seems to work.

This is my MSSQL Server solution, and yep, it outputs EXACTLY like
requested. I'm not sufficiently fluent with MySQL, so this may have
some dialect translation that needs done.
Also, this IS NOT a scalable solution at all. It assumes you know the
years you want the information for, and requires that you specify the
years in two specific areas of the query. Some SQL engines have a cross
tab function that will make this a little more automatic (MSSQL is one
such engine), but they are typically extensions to the SQL spec. and are
specific to each engine (i.e. the MSSQL implementation would not work
for MySQL).
