Hi, 
im facing problem that i have digikam db in mysql and all databases share one database called digikam and i dont want to backup thumbs for example, but only unsefull data. Is there some tool or command(s) that create databases and move existing tables to right databases as described for example > https://docs.digikam.org/en/getting_started/database_intro.html# where every DB has own DB ( btw default setting button do that digikam has same name for all databases, not as described on the image. )
