Summary: misc/cronjobs/update_totalissues.pl problem with
multiple items

misc/cronjobs/update_totalissues.pl when issuing statistics table has a problem
for biblio with multiple items.
The first SQL query gets the biblios linked to items with issues in statistics
:
SELECT biblio.biblionumber, COUNT(statistics.itemnumber) FROM biblio LEFT JOIN
items ON (biblio.biblionumber=items.biblionumber) LEFT JOIN statistics ON
(items.itemnumber=statistics.itemnumber) WHERE statistics.type = 'issue' $limit
GROUP BY biblio.biblionumber
The second SQL query is :
SELECT biblio.biblionumber, 0 FROM biblio LEFT JOIN items ON
(biblio.biblionumber=items.biblionumber) LEFT JOIN statistics ON
(items.itemnumber=statistics.itemnumber) WHERE statistics.itemnumber IS NULL
GROUP BY biblio.biblionumber
The problem is that this second query will set to 0 where ANY item has no entry
in statistics table.
I think the best fix is to use "WHERE statistics.type = 'issue'" inside que
JOIN :
LEFT JOIN statistics ON (items.itemnumber=statistics.itemnumber AND
statistics.type = 'issue')
