Eine Liste nicht leerer Tabellen in einer bestimmten MySQL-Datenbank erhalten?

Um eine Liste nicht leerer Tabellen in einer bestimmten MySQL-Datenbank zu erhalten, lautet die Syntax wie folgt:

SELECT table_type,table_name, table_schema from information_schema.tables
where table_rows >= 1 and table_schema = 'yourDatabaseName';

Implementieren Sie die obige Syntax für Ihre Datenbank. Hier ist unsere Datenbank „test“. Die Abfrage lautet wie folgt -

mysql> select table_type,table_name ,table_schema from information_schema.tables
−> where table_rows >= 1 and table_schema = 'test';

Die folgende Ausgabe zeigt die nicht leeren Tabellen in der Datenbank „test“ -
