Mysql查看数据库表容量大小

Posted 2020-12-20 楔子

1）查看各数据库记录数，容量大小

SELECT
	table_schema AS \'数据库\',
	sum(table_rows) AS \'记录数\',
	sum(
		TRUNCATE (data_length / 1024 / 1024, 2)
	) AS \'数据容量(MB)\',
	sum(
		TRUNCATE (index_length / 1024 / 1024, 2)
	) AS \'索引容量(MB)\'
FROM
	information_schema. TABLES
GROUP BY
	table_schema
ORDER BY
	sum(data_length) DESC,
	sum(index_length) DESC;
