关于查询的Cakephp有可能吗？

Question

我有一个关于cakephp的问题$ this-＆gt;查询是否可以组合三个查询并使其成为一个，？这样的例子

$this->Training->query(Select sample.* from sample where sample.name like "me")
$this->Training->query(Select sample2.* from sample2 where sample2.name like "you")
$this->Training->query(Select sample3.* from sample3 where sample3.name like "us")

这是一个搜索功能组合，2个选择框和1个文本框

Answer 1

只需使用UNION子句，

$this->Training->query(Select sample.* from sample where sample.name like "me"
                 UNION Select sample2.* from sample2 where sample2.name like "you"
                 UNION Select sample3.* from sample3 where sample3.name like "us")
