Question

我有这样的功能代码：

$data_temp = $this->import_m->getPresensi()->result_array();


    $tbl = "tb_kehadiran";    
    $tbl_temp = "tb_kehadiran_temp";
    $db_mysql = $this->load->database('default',TRUE);
    $db_mysql->trans_start();

    foreach($data_temp as $k => $v){

        $dataTemp = array(

            'colUserID' => $v['userID'],
            'colDate' => $v['tanggal'],
            'colJamMasuk' => $v['jam_masuk'],
            'colJamKeluar' => $v['jam_keluar'],
            'colTerlambat' => $v['late'],
            'colLemburPagi' => $v['lembur_pagi'],
            'colLemburSore' => $v['lembur_sore']

            );  

        $sql = "INSER INTO $tbl (
                    'colUserID',
                    'colDate',
                    'colJamMasuk',
                    'colJamKeluar',
                    'colTerlambat',
                    'colLemburPagi',
                    'colLemburSore'
                 ) VALUES (
                    $v[userID],
                    $v[tanggal],
                    $v[jam_masuk],
                    $v[jam_keluar],
                    $v[late],
                    $v[lembur_pagi],
                    $v[lembur_sore]
                ) ON DUPLICATE KEY UPDATE
                    'colJamMasuk' = $v[jam_masuk],
                    'colJamKeluar' = $v[jam_keluar],
                    'colTerlambat' = $v[late],
                    'colLemburPagi' = $v[lembur_pagi],
                    'colLemburSore' = $v[lembur_sore]
                ";
        $db_mysql->query($sql);

    }

    $db_mysql->trans_complete();
    $db_mysql->close();

结果错误：错误号码：1064

您的SQL语法有错误;查看与MariaDB服务器版本对应的手册，以便在

附近使用正确的语法

'INSER INTO tb_kehadiran ( 'colUserID', ' at line 1

如果数据不存在，我希望我的源代码插入数据如果数据存在则不更新。
请帮助我。

Answer 1

代码必须像那样

插入table_name set id =“some_id”， name ='some_name' 重复密钥更新 name ='some_name'

还必须将id字段定义为主键

如果不存在则插入到mysql中，如果是exsist则不要更新
