select 'Customers' as tablename
, count(*) as row_count

union all
select 'Orders' as tablename
, count(*) as row_count

select 'Products' as tablename
, count(*) as row_count

如果你需要在你的数据库里的所有表上做这个查询，青年人网站提示可以从INFORMATION_SCHEMA.TABLES视图生成表清单：
select table_name
from information_schema.tables
where table_schema = 'mydatabase'
然后你可以利用这个查询的结果集和一个文本编辑器生成第一个查询。
