Is it possible to run an UPDATE command on mysql 5.0 with a sub select.
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 is currently stored as a string.
This should be updating 10k+ rows.
Thanks,
William
UPDATE table1 t1, table2 t2
SET t1.field_to_change = t2.field_with_data
WHERE t1.field1 = t2.field2;
UPDATE book_details AS bd, book_details_old AS old
SET bd.live=1
WHERE bd.isbn13=old.isbn13
AND old.live=1;
Just a litle change and you got it:
UPDATE book_details
SET live = 1
WHERE ISBN13 in (SELECT ISBN13 FROM book_details_old WHERE live = 1);
To update a table from data in another table:
UPDATE table1, table2
SET table1.field1 = table2.field1
WHERE table1.id = table2.id;
For example:
UPDATE transaction, member
SET transaction.Memberid = member.memberId
WHERE transaction.CardId = member.CardId;
To Update data From Other Table
UPDATE tab t1, tab t2
SET t1.company_name = t2.company_name
WHERE t1.id = t2.id
