Mysql列表表和大小 - 按大小排序

Question

在mysql中按大小按数据库顺序列出所有表的查询是什么？

Answer 1

试试这个...

SELECT TABLE_NAME, table_rows, data_length, index_length, 
round(((data_length + index_length) / 1024 / 1024),2) "Size in MB"
FROM information_schema.TABLES WHERE table_schema = "schema_name"
ORDER BY (data_length + index_length) DESC;

问候.

Answer 2

在 mysql 客户端中运行以下查询

SELECT table_name AS "Tables", 
round(((data_length + index_length) / 1024 / 1024), 2) "Size in MB" 
FROM information_schema.TABLES 
WHERE table_schema = "$DB_NAME"
ORDER BY (data_length + index_length) DESC;
