用另一个表中的数据更新 mysql 表

2022-01-17 00:00:00 sql-update mysql

是否可以使用子选择在 mysql 5.0 上运行 UPDATE 命令.

Is it possible to run an UPDATE command on mysql 5.0 with a sub select.

我想运行的命令是这样的:

The command I would like to run is this:

UPDATE book_details
SET live = 1 
WHERE ISBN13 = '(SELECT ISBN13 FROM book_details_old WHERE live = 1)';

ISBN13 当前存储为字符串.

ISBN13 is currently stored as a string.

这应该更新 10k+ 行.

This should be updating 10k+ rows.

谢谢，

威廉

推荐答案

稍作改动就搞定了:

UPDATE book_details
SET live = 1 
WHERE ISBN13 in (SELECT ISBN13 FROM book_details_old WHERE live = 1);
