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?

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)
