数组内的SQL LIKE%

Question

我知道如何对单个值执行SQL LIKE%查询,如下所示:

SELECT * FROM users WHERE name LIKE %tom%;

但如果我的LIKE的搜索条件来自数组,我该怎么做？例如,假设我们有一个这样的数组:

$words = array("Tom", "Smith", "Larry");

如何执行我的SQL LIKE%来搜索我的数组中的单词,如:

SELECT * FROM users WHERE name LIKE %[each_element_from_my_array]%

没有将整个查询放在foreach循环或其他内容中

编辑:我忘了提到我在cakePHP中使用cakePHP find('all')方法执行此操作,因此使事情变得复杂一点.

谢谢

Answer 1

$sql = array('0'); // Stop errors when $words is empty

foreach($words as $word){
    $sql[] = 'name LIKE %'.$word.'%'
}

$sql = 'SELECT * FROM users WHERE '.implode(" OR ", $sql);

编辑:CakePHP的代码:

foreach($words as $word){
    $sql[] = array('Model.name LIKE' => '%'.$word.'%');
}

$this->Model->find('all', array(
    'conditions' => array(
        'OR' => $sql
    )
));

Answer 2

在标准SQL的情况下,它将是:

SELECT * FROM users WHERE name LIKE '%tom%' 
                       OR name LIKE '%smith%' 
                       OR name LIKE '%larry%';

既然你使用MySQL就可以使用RLIKE(又名REGEXP)

SELECT * FROM users WHERE name RLIKE 'tom|smith|larry';
