SELECT 
ORDINAL_POSITION, COLUMN_NAME, DATA_TYPE, TABLE_NAME 
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'テーブル名'
ORDERBY ORDINAL_POSITION

出力例

1	ticket_id	bigint	t_ticket
4	ticket_status	tinyint	t_ticket
7	ticket_price	int	t_ticket
10	ticket_create_time	datetime	t_ticket
11	ticket_update_time	datetime	t_ticket

主キーも取得する場合の例

SELECT T1.ORDINAL_POSITION as no, T1.COLUMN_NAME as field, T1.DATA_TYPE as type, T1.TABLE_NAME as tbl, 
 CASE WHEN T2.COLUMN_NAME IS NULL THEN '' ELSE 'PRI' END as 'key'

FROM INFORMATION_SCHEMA.COLUMNS T1
LEFT JOIN INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE T2 
	ON T1.TABLE_NAME=T2.TABLE_NAME AND T1.COLUMN_NAME=T2.COLUMN_NAME 
WHERE T1.TABLE_NAME = 'テーブル名'
ORDER BY T1.ORDINAL_POSITION

出力例
