That resulted in TONS of 404 errors and gaps in the posts that looked rather ugly.So, I needed to replace every instance of oldname.com with newname.com in the posts field without wrecking the posts themselves (that would be a disaster).Your script enabled me to do that with ease and it updated 6,486 rows with the correct domain name :-)I knew it could easily be done with SQL but I didn't know how until I came across your site - thank you!

I think this should work: update posts set content = replace(content,'replace this string','with this one');Or is that not what you meant? Yes. I think this should work: update posts set content = replace(content,‘replace this string’,‘with this one’);

Or is that not what you meant?

For example: i have the word "Jo" `name`table and i want to replace it with "hello". But `name`table i also have the word "John". I haven't tried it but i think this will result in replacing "Jo" with "hello", but will also replace "John" with "hellohn". is there a way of replacing the exact words?
