Question

Have a MySQL database table with 2 columns:
id, url

The url column has values like ‘http://www.example.com/’.

I need to add a string like ‘http://www.x.com?redirect=’ to the beginning of all the column values – i.e. to change the values like this:
http://www.example.com/ ===> http://www.x.com?redirect=http://www.example.com/

Anyone has some clues to how I can do that?

I have looked into using CONCAT(), but so far I haven’t been able to make it work 🙁

Thanks a lot for your help,
Louisa

Answer 1

Using concat it would be like this:

update table set url=concat('http://www.x.com?redirect=',url);
