mysql 聯表查詢

1、注：今天聯表操作做個記錄
select a.*, b.section_name from article_batch_generate a inner join section_info b  on (a.article_category=b.section_id)  WHERE 1=1  ORDER BY task_id DESC

與

select a.*, b.section_name from article_batch_generate a, join section_info b  WHERE 1=1 AND a.article_category=b.section_id ORDER BY task_id DESC是同等的。
