获取 0 到 100 之间的记录而不使用 between in mysql

Question

我想在 mysql 中获取 0 到 100 之间的记录而不使用 between 子句，因为当我使用这样的查询时

$this->db->having('distance between 0 and 100');

我收到如下错误：

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near between0 and 100

您会看到 0 前面没有 space，因此该语句会产生错误。

如何确保 space 保留在 0 之前，否则：如何在查询中排除 between

Answer 1

怎么样

$this->db
    ->group_start()
        ->where('distance <=', 100)
        ->where('distance >=', 0)
    ->group_end();

如果你删除组语句以防万一你不需要它就完全没问题了

Answer 2

使用

$this->db->having(array('distance >=' => 0, 'distance <=' => 100));
// Produces: HAVING distance => 0, distance <= 100

Answer 3

获得这个的两种简单方法

$this->db->select("*");
$this->db->from("table-name");
$this->db->where('distance >=', 0)
$this->db->where('distance <=', 100);
$query = $this->db->get();
return $query->result();

或

$query = $this->db->query("SELECT * FROM table-name WHERE distance <= 100 AND distance >= 0");
return $query->result(); //or $query->result_array();
