Opis

Advanced Database Cleaner is a complete WordPress optimization plugin that helps you clean up database clutter and optimize database performance by removing unused data such as old revisions, auto drafts, spam comments, expired transients, unused post meta, duplicated post meta, unused user meta, etc.

It is designed to help you improve website speed by reducing database bloat and ensuring a lean, efficient WordPress installation. It also provides detailed previews, powerful filters, and automation tools to safely control what gets cleaned.

With the ✨Premium version✨, you can unlock even more advanced features, such as detecting and cleaning orphaned options, orphaned tables, orphaned post meta, orphaned user meta, orphaned transients, and orphaned cron jobs. It also gives you clear insights into how your database evolves over time through built-in analytics, lets you monitor plugin and theme activity to better understand when new data is created or when leftovers appear, and much more.

Dlaczego warto używać Advanced Database Cleaner❓

👉 Get a clear overview: see how many tables, options, transients, cron jobs, metadata… records you have, and identify which are unused or orphaned.

👉 Save time: configure what to clean, how far back to keep data, and how often to run automations. The plugin will then handle recurring cleanups for you.

👉 Save space and improve performance: removing unnecessary data reduces database size, makes backups faster, and can improve query performance, especially on busy or older sites.

Najczęściej zadawane pytania

Dlaczego powinienem „czyścić moją bazę danych”?

As you use WordPress, your database accumulates a large amount of unnecessary data such as revisions, spam comments, trashed comments, and more. This clutter slowly increases the size of your database, which can make your site slower and make backups take longer. Cleaning this data keeps your site lighter, faster, and easier to maintain.

Czy czyszczenie bazy danych jest bezpieczne?

Yes, it is safe. The plugin does not run any code that can break your site or delete posts, pages, or approved comments. It only removes items that WordPress considers unnecessary. However, you should always back up your database before performing any cleanup. This is required, not optional! Backups ensure you can always restore your site if something unexpected happens.

Dlaczego powinienem „optymalizować moją bazę danych”?

Optimizing your database reclaims unused space and reorganizes the way data is stored inside your tables. Over time, tables become fragmented, especially on active websites. Optimization reduces storage usage and improves the speed at which your database responds. This process is safe and can significantly improve performance on large or busy websites.

Czy czyszczenie zadań cron (zadań zaplanowanych) jest bezpieczne?

Cron jobs allow WordPress and plugins to run tasks automatically (like checking for updates or sending emails). When a plugin is removed, some of its cron jobs may remain behind. These leftover tasks serve no purpose and can slow down wp-cron events. Cleaning unnecessary cron jobs is safe as long as you know which ones should be removed. If you are unsure, it is safer not to delete any cron jobs manually.

Czym są „wersje”? Jaki kod SQL jest używany do ich czyszczenia?

WordPress stores revisions for each saved draft or update so you can review older versions. Over time, these accumulate and take up space.
SQL used by the plugin to delete revisions:
DELETE FROM posts WHERE post_type = 'revision’

Czym są „auto-szkice”? Jaki kod SQL jest używany do ich czyszczenia?

WordPress automatically creates auto-drafts while you are editing posts/pages. If those drafts are never published, they remain in the database.
SQL used by the plugin to delete auto-drafts:
DELETE FROM posts WHERE post_status = 'auto-draft’

Czym są „oczekujące komentarze”? Jaki kod SQL jest używany do ich czyszczenia?

Pending comments are comments waiting for your approval. If you have many bots submitting comments, this list can grow quickly.
SQL used by the plugin to delete pending comments:
DELETE FROM comments WHERE comment_approved = '0′

Czym są „komentarze spamowe”? Jaki kod SQL jest używany do ich czyszczenia?

Spam comments are comments flagged as spam by you or by an anti-spam plugin. They can safely be deleted.
SQL used by the plugin to delete spam comments:
DELETE FROM comments WHERE comment_approved = 'spam’

Czym są „komentarze w koszu”? Jaki kod SQL jest używany do ich czyszczenia?

Trash comments are deleted comments moved to the trash. They are no longer visible and can be permanently removed.
SQL used by the plugin to delete trash comments:
DELETE FROM comments WHERE comment_approved = 'trash’

Czym są „trackbacki”? Jaki kod SQL jest używany do ich czyszczenia?

Trackbacki to przestarzały system WordPress, który umożliwia jednej stronie internetowej powiadomienie innej o umieszczeniu odnośnika do jej treści. Gdy strona otrzyma trackback, pojawia się on jako rodzaj komentarza do wpisu. Ponieważ trackbacki można wysyłać ręcznie, stały się one bardzo nadużywane przez spamerów, którzy wykorzystują je do publikowania niechcianych odnośników witrynach internetowych.
Kod SQL używany przez wtyczkę do usuwania trackbacków:
DELETE FROM comments WHERE comment_type = 'trackback’

Czym są „pingbacki”? Jaki kod SQL jest używany do ich czyszczenia?

Pingbacki to zautomatyzowany system powiadomień używany przez WordPress. Gdy jedna witryna internetowa publikuje odnośnik do wpisu na innej stronie, WordPress wysyła żądanie pingback do powiązanej witryny. Po zaakceptowaniu, pingback pojawia się jako rodzaj komentarza, potwierdzając, że inna strona odniosła się do twojej treści. Ponieważ pingbacki są zautomatyzowane, często są wykorzystywane przez boty do generowania żądań spamu.
Kod SQL używany przez wtyczkę do usuwania pingbacków:
DELETE FROM comments WHERE comment_type = 'pingback’

Czym jest „nieużywane post meta”? Jaki kod SQL jest używany do jego czyszczenia?

Metadane wpisu przechowują dodatkowe informacje o wpisach. Po usunięciu wpisu niektóre dane meta mogą pozostać. Te pozostałe „nieużywane” dane mogą z czasem zwiększać swą objętość.
Kod SQL używany przez wtyczkę do usuwania nieużywanych danych meta wpisu:
DELETE pm FROM postmeta pm LEFT JOIN posts wp ON wp.ID = pm.post_id WHERE wp.ID IS NULL

Czym jest „nieużywane comment meta”? Jaki kod SQL jest używany do jego czyszczenia?

Comment meta stores extra information for comments. When a comment is removed, some metadata may remain in the database.
SQL used by the plugin to delete unused comment meta:
DELETE FROM commentmeta WHERE comment_id NOT IN (SELECT comment_ID FROM comments)

Czym jest „nieużywane user meta”? Jaki kod SQL jest używany do jego czyszczenia?

Dane meta użytkownika przechowują dodatkowe dane o użytkownikach. Jeśli użytkownik zostanie usunięty, jego dane meta mogą nie zostać usunięte automatycznie.
Kod SQL używany przez wtyczkę do usuwania nieużywanych metadanych użytkownika:
DELETE FROM usermeta WHERE user_id NOT IN (SELECT ID FROM users)

Czym jest „nieużywane term meta”? Jaki kod SQL jest używany do jego czyszczenia?

Dane meta terminów przechowują dodatkowe informacje o terminach taksonomicznych (kategoriach, tagach itp.). Jeśli termin zostanie usunięty, jego dane meta mogą pozostać.
Kod SQL używany przez wtyczkę do usuwania nieużywanych metadanych terminów:
DELETE FROM termmeta WHERE term_id NOT IN (SELECT term_id FROM terms)

Czym są „nieużywane relacje”? Jaki kod SQL jest używany do ich czyszczenia?

Tabela wp_term_relationships łączy wpisy z kategoriami/tagami. Po usunięciu wpisów powiązane wpisy mogą pozostać w tej tabeli, zajmując niepotrzebnie miejsce.
Kod SQL używany przez wtyczkę do usuwania nieużywanych relacji:
DELETE FROM term_relationships WHERE term_taxonomy_id=1 AND object_id NOT IN (SELECT id FROM posts)

Czym są „wygasłe transients”?

Dane tymczasowe (transjenty) to tymczasowe dane buforowane przez wtyczki lub motywy. Po wygaśnięciu powinny zostać automatycznie usunięte. Jednak niektóre przestarzałe dane tymczasowe mogą pozostać w bazie danych. Można je bezpiecznie usunąć, aby zwolnić miejsce.

Czy wtyczka jest zgodna z siecią stron?

Tak, wtyczka jest kompatybilna z wieloma witrynami. Ze względów bezpieczeństwa tylko witryna główna może czyścić bazę danych w całej sieci. Witryny podrzędne nie mogą wykonywać operacji czyszczenia, aby uniknąć przypadkowego uszkodzenia.

Czy ta wtyczka jest kompatybilna z SharDB, HyperDB lub Multi-DB?

Jeszcze nie. Wtyczka nie jest obecnie kompatybilna z konfiguracjami SharDB, HyperDB ani Multi-DB. Obsługa może zostać dodana w przyszłych wersjach.

Czy ta wtyczka czyści się sama po odinstalowaniu?

Tak. Wtyczka usuwa wszystkie swoje dane i ustawienia po odinstalowaniu. Wtyczka czyszcząca, która pozostawia bałagan, nie ma sensu!

[Pro version] Staging sites count toward the activation limits

2026-09-02 1 odpowiedź
Be aware that staging sites count towards the activation limits. I’m lowering my review because of that as this has serious implications in my workflow. The developer is aware of this for some time but has yet to prioritize pushing a fix.

Casi no lo uso

2026-09-02 1 odpowiedź
Casi no uso el plugin y me pide constantemente, a través de un cuadro, que ponga mi reseña. La verdad es que es un poco (mucho) intrusivo. Se dijo lo que se tenía que decir.
