SQL Server Management Studio — znajdowanie wszystkich niepustych tabel

Możesz spróbować użyć sysindexes i INFORMATION_SCHEMA.TABLES :)

SELECT 'Table Name'=convert(char(25),t.TABLE_NAME),
      'Total Record Count'=max(i.rows)
FROM sysindexes i, INFORMATION_SCHEMA.TABLES t
WHERE t.TABLE_NAME = object_name(i.id)
      and t.TABLE_TYPE = 'BASE TABLE'
GROUP BY t.TABLE_SCHEMA, t.TABLE_NAME
HAVING max(i.rows)>0
ORDER BY 'Total Record Count' DESC
