Database A is located directly in the IsolatedStoreFile root folder (the local folder). I am trying to attach database B to A. B is located in a subdirectory:
Attach query on A:
"ATTACH '/subdir/B.sqlite' as AttachedDB"
This query fails with the return code "DatabaseOpenError". This problem does not occur if B is locates in the same folder as A:
"ATTACH 'B.sqlite' as AttachedDB"
But how can I attach a db that is located in a different folder? How to specify the path correctly?
