how to query from Calibre database?
質問
as you know calibre has a database called metadata.db
and made of SQLite,
I want to query from all books with this columns :
bookId Title Date Size Rating Tags Publisher PublishedDate Author Cover
------ ----- ---- ---- ------ ---- --------- ------------- ------ -----
but, that database contains this tables :
Books Table
-----------
Name
id
title
sort
timestamp
pubdate
series_index
author_sort
isbn
lccn
path
flags
uuid
has_cover
last_modified
Authors Table
-------------
Name
id
name
sort
link
Publishers Table
----------------
Name
id
name
sort
there is no relationship between them, how can I get my query?
