MySQL：SQL查看表占用空间

SELECT table_schema AS '数据库', table_name AS '表名', table_rows AS '记录数',
TRUNCATE(data_length / 1024 / 1024, 2) AS '数据容量(MB)',
TRUNCATE
	(index_length / 1024 / 1024, 2) AS '索引容量(MB)'
FROM
	information_schema.tables
WHERE
	table_schema = '填写要查询的数据库名称'
ORDER BY
	data_length DESC,
	index_length DESC;
