Question

使用

检索表

#+begin_src sql :engine mysql :dbuser org :database grocer
show tables;
#+end_src

#+RESULTS:
| Tables_in_grocer |
|------------------|
| Customers        |
| OrderItems       |
| Orders           |
| Products         |
| Vendors          |

然后依次查看每个表

select * from Vendors; 
select * from Products;
select * from Customers;
select * from Orders;
select * from OrderItems;

是否可以将循环用作

for table in tables
    select * from table;

Answer 1

也许是这样？（如果您只需要查询）

select CONCAT('SELECT * FROM ',table_name,';')
from information_schema.tables
where table_type = 'BASE TABLE'
    and table_schema = 'your_schema_name'
order by table_schema, table_name;

如果您希望直接访问结果，我认为您可以将其提取到CSV文件（How to output MySQL query results in CSV format?）

为此，您只需修改查询生成器并执行生成的代码即可。
