mysql 如何查看表的大小

mysql 查看表的大小方法:

1.查看所有数据库容量大小selecttable_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.tablesgroup by table_schemaorder by sum(data_length) desc, sum(index_length) desc;2.查看所有数据库各表容量大小selecttable_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.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selecttable_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selecttable_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;以上就是mysql 如何查看表的大小的详细内容,更多请关注小潘博客其它相关文章!
