    3. COPlease can you clarify the following: "Without use db route, because I need all auth database and select to get in a specific database all other is set in my UserProfile database name, and I I try to use router but doesn't work." - am I correct in thinking that you have 2 databases, one which contains all the auth data and one which contains all the other data, including the UserProfile?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
