Как посмотреть размер всех таблиц

Question

Я по ошибке создал таблицу в своей базе данных, в которой нет строк, и я хочу знать системный c способ узнать эту таблицу. Я знаю, что мы можем использовать sp_spaceused, чтобы получить количество строк, но как я могу сделать это для всех таблиц.

Вставьте вывод следующего запроса в новый SQL редактор и проведите визуальное сканирование вывода

SELECT *
FROM (
    SELECT 1000 * ROW_NUMBER () OVER (ORDER BY name) rk,
        ' sp_spaceused ' + name spused
    FROM sys.Tables
    UNION ALL
    SELECT 1 + 1000 * ROW_NUMBER () OVER (ORDER BY name), ' go'
    FROM sys.Tables
) a
ORDER BY a.rk
