如何使用codeigniter编写此查询？

Question

如何编写与活动记录类似的选择查询？

SELECT * FROM test_tbl WHERE date BETWEEN '$start' and '$end' ORDER BY ID 

问候

Answer 1

AFAIK， BETWEEN没有内置支持

你可以这样做

$this->db->where("date BETWEEN '$start' AND '$end'");
$this->db->get("test_tbl");  

或者编写一个看起来像这样的辅助函数

function where_between($field, $min, $max){
     $CI = get_instance();
     return $CI->db->where("`$field` BETWEEN '$min' AND '$max'");
}  

稍后，您可以通过调用它来使用该函数，如where_between('test_tbl', $start, $end)
