无法以铁路的神秘结果获取信息
原标题:Cannot get information in mysql result with rails

I m 使用有活性污染物的铁路。 我想从我的智慧数据库中挑选一些信息。

sql = ActiveRecord::Base.connection();
s="SELECT word FROM dics WHERE word LIKE  tung% ";
ten = sql.execute(s);

但是,当我用“天线”印制屏幕时,它表明:

#<Mysql2::Result:0x4936260>

How can I get the information of records?

最佳回答

我建议你不要直接使用<代码>活性记录:Base.linkion。 与ARel syntax做勾划,在大多数情况下,你的例子似乎好像是edge。

如上述评论所述,努力做到如下:

dics = Dic.select(:word).where(["word LIKE ?", "tung%"]).all

为了压缩某些特殊物体领域,而不是物体本身,使用<条码> pl/条码>而不是<条码>。

# instead of .pluck(:word) use real field identifier
dics = Dic.where(["word LIKE ?", "tung%"]).pluck(:word)
