显示Fields FROM Mysql Table的注释

Question

SHOW COLUMNS FROM <tablename>给出表中列的所有信息,除外Comments.

如何提取Comments信息？我知道从INFORMATION SCHEMA中提取信息的方法,但是如何将结果组合在一个结果集中？

Answer 1

您可以使用该查询

SHOW FULL COLUMNS FROM <tablename>

如果你不想使用information_schema.

Answer 2

select `column_name`, `column_type`, `column_default`, `column_comment`
from `information_schema`.`COLUMNS` 
where `table_name` = 'table-name' 
and `table_schema` = 'db-name';

Answer 3

如果您想获取表格注释：

SELECT table_comment
FROM INFORMATION_SCHEMA.TABLES
WHERE table_name = 'my_table' and 
      table_schema = 'my_database'
