加入操作犯规给两个表

Question

列

嘿我想加入使用的find_by_sql轨的方法两个表，但我不明白的“fb_ppl_pages”表中的列：

"FbPage.find_by_sql("select * from fb_pages as t1 join fb_ppl_pages as t2 on t1.user_id=t2.user_id where t1.category='community'")" 

怎么办我得到两个表的列？

Answer 1

"FbPage.find_by_sql("select fb_pages.*,fb_ppl_pages.* from fb_pages as t1 join fb_ppl_pages as t2 on t1.user_id=t2.user_id where t1.category='community'")" 

选择fb_pages.*,fb_ppl_pages.*应该给你的所有属性
