Hi Simon,
yes, I know. But I thought that the "alter table / drop table / add column..." statements were a regular feature of your application (which seems a bit unusual to frequently add columns and then later delete them, but I thought that was how your application was designed...).
In that case it would make sense to have the table table name which crashed the database of 7.9, because very similar statements should also be in the sysddhistory for 7.8.
But maybe my assumptions were wrong...
Regards,
Thorsten
