我正在将一些发现从cakephp2转换为cakephp3。 我需要搜索存储在不同列上的导师表上的名字和姓氏。根据文档,我需要在表格之间加入左连接。我已经使用了2个字段的条件,但是如果两个参数都有一个值,那么它和'和'条件一样。 我的问题是在CakePHP 3中生成OR SQL语句
q1) I cant get the data with just the first name only , and the surname is null.
q2) I need to pass both first name and surname to get just those data with that name.
Not sure how to do this in cakephp3.
eg $a5='fred'; //just want all first names like fred
$a6=null; //sometimes this will be filled
$a3='2015-05-30';
$a4='2016-06-01';
$query3 = $this->Lessons->find()
->contain(['Tutors'])
->select(['lessons.id','lessons.lesson_date','tutors.id','tutors.first_name','tutors.last_name' ])
->where(['Lessons.lesson_date >' => $a3,'Lessons.lesson_date <' => $a4,
'OR' => [['tutors.first_name like' => '%'.$a5.'%'], ['tutors.last_name like' => '%'.$a6.'%']],
]);
foreach ($query3 as $row) {
debug($row->toArray());
}
我不明白这一点的文档。 http://book.cakephp.org/3.0/en/orm/query-builder.html#advanced-conditions
更新 - 尝试这一点,这也只是给所有的数据与'at'或'to',但它应该是任何名称都'at'和'to'在他们。
$query3 = $this->Lessons->find()
->contain(['Tutors','Subjects', 'TutoringTypes','Terms','Students'])
->select(['lessons.id','lessons.lesson_date','tutors.id','tutors.first_name','tutors.last_name',
'subjects.id','subjects.name','terms.id','terms.title'])
->where(['Lessons.lesson_date >' => $a3,'Lessons.lesson_date <' => $a4])
->orWhere(function ($exp) {
return $exp->and_([
'tutors.first_name like' => '%an%',
'tutors.last_name like' => '%to%',
]);
});
