Digikam not displaying photos after computer reinstall

Hi,

I was wondering if MariaDB might work! I had a brief look at the v7 to
v8 upgrade scripts and noticed that it uses "IF EXISTS". That isn't
supported in MySQL (only supported in MariaDB 10.0 upwards). I guess
that means that upgrades are not supported for MySQL at all.

I think that practically any user with a pre v8 database (I think that
means a database created in digikam 4.x or earlier) is best advised to
migrate the old database into a new database. The digikam 5.x
MySQL/MariaDB changes corrected a lot of previous problems and will give
you a database that should work correctly.

There can be some issues migrating an existing database due to previous
bugs/features.

I provided some mysql commands to help cleanup the data in bug 355831
https://bugs.kde.org/show_bug.cgi?id=355831
specifically
https://bugs.kde.org/attachment.cgi?id=99906

Recently I've suggested some changes to the migration that ignore the
bad data during migration. That is not included in digikam yet.
https://bugs.kde.org/show_bug.cgi?id=382732

I would really sugggest that you try a migration to a clean database. I
have done that with my databases to ensure minimal problems at a later date.

Regards

Richard
