在Kohana数据库中列的BETWEEN

Question

如何指定

NOW() BETWEEN col1 AND col2

使用Kohana数据库？

$this->where(new Database_Expression('NOW()'), 'BETWEEN', array('col1', 'col2'));

显然将值视为字符串文字，而不是列名

Answer 1

你试过吗

$this->where(DB::expr('NOW() BETWEEN col1 AND col2'));

编辑：

$this->where('NOW()', 'BETWEEN', DB::expr('col1 AND col2'));

Answer 2

阅读一些代码并获得它：

$this->where(null, null, new Database_Expression('NOW() BETWEEN col1 AND col2'));
