Can't set up database library

Hi,
I want to set up database library, but I can’t. So how it should set up?
I try several tutorial on this forum, also from cdwilson.dev
However, It fails.

I edit the kicad_dbl file, several connection string. And finally no error message at library reload. However, the table didn’t shown

Here the edited files
VendorsDB.kicad_dbl (3.9 KB)
VendorsDB.sqlite (136 KB)

I didn’t change the database content yet.

Here the entry of library tables:

However, it didn’t show on library search using nickname:
vendor search as nickname

Also I try table name and item name, but nothing.

Solved. The Database library not shown on symbol editor. Only on symbol library browser or place component. Looks like this is the best option because DB library is not editable from KiCAD.
