需要按RAND排序此SQL结果

Question

I have the following sql and need to sort the results in random order. I tried adding ORDER BY RAND() but was unsuccessful. I may be missing the syntax on it.

$items = Goods_Model_Good::findByCop(array(
       'where' => new JO_Db_Expr(
             'good.id IN (SELECT id
                            FROM good
                            WHERE copId LIKE ' . Helper_Db::quote($cop['copId']) .
     ')')));

Answer 1

在PHP中，您可以使用shuffle来对数组进行混洗：

shuffle($items);
