项目数据批量维护

推荐用存储过程更新数据，不会的话可以用以下方法。

项目中某个表中的数据需要维护，数据量巨大。

1.首先将要维护的数据筛选出来，编写脚本执行变量的sql更新操作。

2.csv文件中去批量更新数据，保存文件。

<?php
//ImportCsv.php
set_time_limit(60);

$link = mysql_connect("localhost","root","orbit");
mysql_select_db("wms_site_ks01");
$filePath_unite = "./job_item_id.csv";

if (is_file($filePath_unite)) {
	$handle_unite = @fopen($filePath_unite,"r");
	$key=0;
	while ($data_unite = fgetcsv($handle_unite, 1000, ",")) {
		if($key>0){
			echo "update stock_moves set job_item_id='".$data_unite['9']."' where stock_mv_id=".$data_unite['0'].";"."<br/>";
			//mysql_query("update stock_moves set job_item_id='".$data_unite['9']."' where stock_mv_id=".$data_unite['0']) or die("Invalid query: " . mysql_error());
		}
		$key++;
		//print "<pre>";print_r($data_unite);die;
	}

	fclose($handle_unite);
}else {
	die("File does not exist");
}
?>

 例子二 加处理条数限制防止程序内存溢出或处理超时，再加页面自己刷新即可解决，新建导入字段，导入后更新，导完后删除字段import即可

<?php
set_time_limit(0);
$sql = "select * from core_catalog where level=3 and import=0 limit 30";
$result = Yii::app()->db->createCommand($sql)->queryAll();
foreach ($result as $var3 => $key3) {
    $url = "http://wbmall.bama555.com/api//props?cid=" . $key3['id'] . "&app_key=5318260b3d8f0036";
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // 获取数据返回
    curl_setopt($ch, CURLOPT_BINARYTRANSFER, true); // 在启用 CURLOPT_RETURNTRANSFER 时候将获取数据返回
    $output = curl_exec($ch);
    $data = json_decode($output, true);
    foreach ($data as $info) {
        $sql = "insert into core_catalog_standard(id, catalog_id, pid, level, name,title,sort)
                    values({$info['id']}, {$info['gcat_id']}, 0, 1, 'stand_{$info['id']}', '{$info['name']}', {$info['listorder']});";
        Yii::app()->db->createCommand($sql)->execute();
    }
    $sql = 'update core_catalog set import=1 where id=' . $key3['id'];
    Yii::app()->db->createCommand($sql)->execute();
    echo 'complate' . $level . "共：" . count($data);
    echo "<script>setTimeout(window.location.href=window.location.href, 3000);</script>";
    exit;
}
