php使用mysql分批大量插入数据

之前由于误删数据,需要恢复,但是不能影响线上服务:

public function insertData()
{
    $number = 11020095;
    $interval = 500000;
    $file_name = ' /tmp/table_name_12220095.sql';
    for ($i = 1; $i < 100; $i++) {
        $samll = $number - $interval * $i;
        if ($samll > 0) {
            $big = $samll + $interval;
            echo sprintf('mysqldump -h db_host -u db_user -p db_password table_name --where="id>=%s and id<%s" >%s', $samll, $big, $file_name) . PHP_EOL;
            sleep(1);
        }
    }
}

批量检查遗漏的ID:

public function checkNotExist()
{
    // 每次调用之前清空之前的数据
    file_put_contents(LOG_ROOT . '/Log/not_exist.txt', '');
    $number = 12270095;
    $intrval = 10000;
    for ($i = 0; $i < $number; $i++) {
        $small = $i * $intrval;
        $big = $small + $intrval - 1;
        $arr = range($small, $big);
        if ($big > $number) {
            return $this->writeJson(sprintf('已完成,大值%s,小值%s', $big, $small));
        }
        $ids = XxModel::create()->where('id', [$small, $big], 'between')->column('id');
        $str = '';
        if (empty($ids)) {
            $str = implode(',', $arr);
        } elseif (count($ids) != $intrval) {
            $str = implode(',', array_diff($arr, $ids));
        }
        if ($str) {
            file_put_contents(LOG_ROOT . '/Log/not_exist.txt', $str . PHP_EOL, FILE_APPEND);
        }
        // usleep(100);
    }
}
