Question

I have a simple CMS running PHP/MySQL and I’m looking for the most efficient way to update LONGTEXT fields across multiple tables when I change the title/url for a page.

For example:
I change the page “/contact” to “/contact-us” and I want any LONGTEXT fields across multiple tables containing

...<a href="/contact">...

to update to

...<a href="/contact-us>"...

I know I could just do a SELECT, match records and replace, but I’m thinking there has to be some method that’s lighter on the MySQL…

Answer 1

I found this:

UPDATE table SET some_column = REPLACE(some_column, 'href="/contact', 'href="/contact-us')

Which appears to do exactly what I’m looking for.
