Question

$this->db->select('*');
    $this->db->from('draw');
    $this->db->where('Bond#' >= $data['from']);
    $this->db->where('Bond#' <= $data['to']);
    return $this->db->get();

这是我的查询，但它显示了此输出：

数组（[list] =＆gt; CI_DB_mysqli_result对象（[conn_id] =＆gt; mysqli对象（[affected_rows] =＆gt; 0 [client_info] =＆gt; mysqlnd 5.0.11-dev - 20120503 - $ Id：76b08b24596e12d4553bd41fc93cccd5bac2fe7a $ [client_version] =＆gt; 50011 [connect_errno] =＆gt; 0 [connect_error] =＆gt; [errno] =＆gt; 0 [错误] =＆gt; [error_list] =＆gt;数组（）[field_count] =＆gt; 8 [ host_info] =＆gt; localhost通过TCP / IP [info] =＆gt; [insert_id] =＆gt; 0 [server_info] =＆gt; 5.7.17 [server_version] =＆gt; 50717 [stat] =＆gt;正常运行时间：1930线程： 1个问题：1153慢查询：0打开：135刷新表：1打开表：122每秒查询平均值：0.597 [sqlstate] =＆gt; 00000 [protocol_version] =＆gt; 10 [thread_id] =＆gt; 101 [warning_count] = ＆gt; 0）[result_id] =＆gt; mysqli_result对象（[current_field] =＆gt; 0 [field_count] =＆gt; 8 [length] =＆gt; [num_rows] =＆gt; 0 [type] =＆gt; 0）[result_array ] =＆gt; Array（）[result_object] =＆gt; Array（）[custom_result_object] =＆gt; Array（）[current_row] =＆gt; 0 [n um_rows] =＆gt; [row_data] =＆gt; ））

Answer 1

您应该使用where子句中的逗号（，）来分隔列名和数据。

像这样更改查询。

$this->db->select('*');
    $this->db->from('draw');
    $this->db->where('Yourfieldname >=', $data['from']);
    $this->db->where('Yourfieldname  <=', $data['to']);
    return $this->db->get();

Answer 2

根据文档，您必须使用列名替换Bond＃并更改您的查询：https://www.codeigniter.com/user_guide/database/query_builder.html#looking-for-specific-data

$this->db->select('*');
$this->db->from('draw');
$this->db->where('Bond# >=', $data['from']);
$this->db->where('Bond#', $data['to']);
return $this->db->get();

Bond＃必须是查询中列的名称。
