MySQL如何显示给定表的列信息？

Question

SHOW COLUMNS显示有关给定表的所有列的信息。但是，我如何仅显示一个特定列或某些列？

Answer 1

您可以直接使用系统表

select *
from information_schema.columns
where table_name = 'your_table'
and column_name = 'some_column_name'

Answer 2

您可以使用WHERE子句

SHOW  COLUMNS FROM `table_name` WHERE `field` ='your columns name'

或者您可以使用LIKE

SHOW  COLUMNS FROM `table_name` WHERE `field` LIKE '%your columns name%'

As docs already defined

Select columnname From table LIMIT 1
