1、注：今天联表操作做个记录
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
与
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。
