why not just filter them in sql?

[shabnix]

I initially attempted to filter it in SQL using the following query:

CREATE VIEW updatesView AS
SELECT
    mangas._id AS mangaId,
    mangas.title AS mangaTitle,
    chapters._id AS chapterId,
    chapters.name AS chapterName,
    chapters.scanlator,
    chapters.read,
    chapters.bookmark,
    chapters.last_page_read,
    mangas.source,
    mangas.favorite,
    mangas.thumbnail_url AS thumbnailUrl,
    mangas.cover_last_modified AS coverLastModified,
    chapters.date_upload AS dateUpload,
    chapters.date_fetch AS datefetch
FROM mangas JOIN chapters
ON mangas._id = chapters.manga_id
LEFT JOIN excluded_scanlators  -- added
ON mangas._id = excluded_scanlators.manga_id -- added
AND chapters.scanlator = excluded_scanlators.scanlator --added
WHERE favorite = 1
AND date_fetch > date_added
AND excluded_scanlators.scanlator IS NULL -- added
ORDER BY date_fetch DESC;

I couldn’t get the query to work, so I filtered in code instead.
