Hi Has anyone got a blockboard 5 and blackboard 6 system which should match after a migration? Is so the following SQL script may be usefull to see if any content is missing (we use SQL 2000 on Windows 2000). select distinct bb5cm.course_id from bb_bb60.dbo.course_contents bb6cc right outer join bb50.dbo.course_contents bb5cc on bb5cc.pk1 = bb6cc.pk1 inner join bb50.dbo.course_main bb5cm on bb5cm.pk1 = bb5cc.crsmain_pk1 where bb6cc.pk1 is NULL and bb5cc.folder_ind = 'N' and bb5cm.course_id not like 'TEMP_%' order by bb5cm.course_id You need access to both databases and can modify the where clause to excluded any courses you have filtered. Please let me know if anyone finds any problems as we are currently finding content missing. Also please let me know if you find any problems or improve the SQL script.
