使用 Mysql 检索最后插入的 id

2021-11-20 00:00:00 node.js mysql

美好的一天,

我愿意在Mysql中检索新插入行的id值.

I am willing to retrieve the id value of a freshly inserted row in Mysql.

我知道有 mysqli_insert_id 函数,但是:

I know there is mysqli_insert_id function, but:

  1. 我无法指定表格
  2. 如果同时进行查询,可能会有检索到错误 ID 的风险.
  3. 我正在使用 node.js MySQL

我不想冒险去查询最高的 id,因为有很多查询,它可能会给我错误的...

I don't want to take the risk to query the highest id since there are a lot of queries, it could give me the wrong one...

(我的 id 列是自动递增的)

(My id column is on auto-increment)
