Javascript 选择的流结果将同时运行多个更新

使用mysqljs节点模块，我正在更新一个查询，该查询在MySQL中对一个超过200万行的大表进行更新，以避免锁定该表。因此，我想对结果行进行大量的选择和迭代，以单独更新它们。我不介意同步更新

以下是我尝试过的：

常数一小时=1000*60*60； const pool=mysql.createPool{ 连接限制：10， 主机：process.env.MYSQL\u主机， 用户：process.env.MYSQL\u用户， 密码：process.env.MYSQL\u PASS， 数据库：process.env.MYSQL\u DB }; const rowHandler=行=>{ pool.query` 更新成员m集 今天收到的通知= 选择COUNTid 来自 其中r.member_id=m.id

DATEDIFFNOW，r.action\u date不确定为什么要用php标记它。看起来像node.js，对吗？是的，但如果php中有一个允许并发更新的解决方案，它将被acceptedTag删除，但为了简单起见
