I tried to run the following SQL Query
Code:
SELECT book FROM books_custom_column_9_link
WHERE value IN
( SELECT value
FROM books_custom_column_9_link
GROUP BY value
HAVING COUNT(*) > 1 )
and got this error:
Code:
calibre, version 3.6.0
ERROR: MCS: Raw SQL Query Fatal Error: SQLError: no such table: books_custom_column_9_link
Since I changed the 9. expression in the Regular Expression tab can I use one of the other expressions and what do I write?
