使用另一个表的数据更新mysql表

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

是否可以使用子select在mysql 5.0上运行更新命令。

The command I would like to run is this:

我想运行的命令是:

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

ISBN13 is currently stored as a string.

ISBN13目前存储为一个字符串。

This should be updating 10k+ rows.

它应该更新10k+行。

Thanks,

谢谢,

To update a table from data in other table

从其他表中的数据更新表

UPDATE table1, table2 SET table1.field1 = table2.field1 where table1.id = table2.id

更新表1，表2设置表1。field1 =表二。field1表1。id = table2.id

EX.UPDATE transaction, member SET transaction.Memberid = member.memberId WHERE transaction.CardId = member.CardId;

更新事务，成员设置事务。Memberid =成员。memberId地方事务。CardId = member.CardId;
