Mysql wpdb&x27；加载数据文件'；

我正在使用wpdb类来运行加载数据本地填充。它工作正常，数据插入正确-但它仍然返回0，因此在示例中回显“No Update”。这是基于负载数据方法的预期结果吗？如果是这样，是否有其他方法可以知道进程运行并确实插入了行

多谢

global $wpdb;
$filename = 'file.csv';
$sql = "LOAD DATA LOCAL INFILE '" . $filename . "'
INTO TABLE Stock_Item
FIELDS TERMINATED BY ',' ENCLOSED BY '\"' ESCAPED BY '\"' LINES TERMINATED BY '\n' IGNORE 1 ROWS
(stock_item_code, stock_item_name)"; 

$result = $wpdb->query($sql);           
if ($result === false) { echo 'Query Fail'; }
if ($result === 0) { echo 'No update'; }
if ($result > 0) { echo 'Success'; }

我是这样做的

global $wpdb;
        $datafile= $_FILES['file']['tmp_name'];
        $file=$upload_dir['basedir'].'/'.$_FILES['file']['name'];
        $fileurl=$upload_dir['baseurl'].'/'.$_FILES['file']['name'];
        if (!move_uploaded_file(
        $_FILES['file']['tmp_name'],
        $file)) {
        print_r('Failed to move uploaded file.');
        }
        $sql="
        LOAD DATA LOCAL INFILE '".$fileurl."' INTO TABLE ".CRSSEARCH_TABLE."
        FIELDS TERMINATED BY ',' 
        LINES TERMINATED BY '\r\n'
        (ucn,name, course_number, standard, accredition,attended_course_form,attended_course_to,status,validity,location);
        ";
        $query = $wpdb->query($sql);

对我来说工作很好，就像魅力一样
