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.tablesorder by data_length desc, index_length desc; 3.查看指定数据库容量大小例:查看mysql库容量大小 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.tableswhere table_schema='mysql'; 4.查看指定数据库各表容量大小例:查看mysql库各表容量大小 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.tableswhere table_schema='mysql'order by data_length desc, index_length desc; 本文讲解了如何通过MySQL查看数据库表容量大小,更多相关内容请关注php中文网。 相关推荐: 关于php str_getcsv把字符串解析为数组的使用方法的讲解
