使用来自另一个表的数据更新mysql表 [英] Update mysql table with data from another table

问题描述

是否可以在带有子选择的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.

我要运行的命令是这样:

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

推荐答案

只需更改一下即可，

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