在触发器中获取最新插入的 ID?

I use a trigger to insert a row and want to use the last created id for using in the subsequent query.

我怎么能这样做?

代码如下:

BEGIN
IF (NEW.counter >= 100) THEN
INSERT INTO tagCategories (name, counter) VALUES ('unnamed', NEW.counter);
// here i want to have access to the above inserted id
UPDATE tagCategories2tagPairs SET tagCategoryId = <<ID_HERE>> WHERE tagPairId = OLD.id
END IF;
END

推荐答案

你看过 LAST_INSERT_ID()?但请注意:

如果您使用 a 插入多行单个 INSERT 语句，LAST_INSERT_ID() 返回值为第一个插入的行生成仅.
