comparison schema/updates/1310/01.import-changed.sql @ 4748:47922c1a088d
Added a 'changed' column to the import.imports table.
Changed is update each time the state changes (TODO: solve this with a trigger).
The update script takes as approximation the time of the last log entry
connected with the particular import.
