If the 'statistics' table contains circulation information about items
that are no longer on the DB it will raise a warning. This patch
makes the updatedatabase.pl script use the deleteditems and deletedbiblioitems
tables to get information for those items on the statistics table.
To reproduce:
- Have your sample DB contain some circulation data on the statistics table
- Make sure some of them have NULL itemtype:
> UPDATE statistics SET itemtype = NULL WHERE type='return';
- Check the upgrade query catches them:
> SELECT s.itemnumber, i.itype, b.itemtype FROM ( SELECT DISTINCT itemnumber FROM statistics WHERE ( type = "return" OR type = "localuse" ) AND itemtype IS NULL ) s LEFT JOIN ( SELECT itemnumber,biblionumber, itype FROM items UNION SELECT itemnumber,biblionumber, itype FROM deleteditems ) i ON (s.itemnumber=i.itemnumber) LEFT JOIN ( SELECT biblionumber, itemtype FROM biblioitems UNION SELECT biblionumber, itemtype FROM deletedbiblioitems ) b ON (i.biblionumber=b.biblionumber);
+------------+-------+----------+
| itemnumber | itype | itemtype |
+------------+-------+----------+
| 732 | BK | BK |
| 731 | BK | BK |
+------------+-------+----------+
2 rows in set (0.00 sec)
- Delete the items, and some biblio too.
- Re-run the query
=> SUCCESS: Same results
- Go reset to NULL the itemtypes
> UPDATE statistics SET itemtype = NULL WHERE type='return';
- Run the updatedatabase.pl script:
$ sudo koha-shell koahdev ; cd kohaclone
$ perl installer/data/mysql/updatedatabase.pl
=> SUCCESS: No warnings
Note: It is possible that on production sites, if the sysadmin is cleaning the
deleted{items|biblioitems|biblio} tables, there will be warnings. This is expected
as they need to know some data lacks information.
