MySQL Query needed: I need to delete all data from a single column

Question

I have an ecommerce store that I am currently working on and there are approx 300 products which have a field named "product_url"

These fields contains an old url that I need to delete altogether.

How can I create a query that will replace all "product_url" fields with data in them witha null value?

Answer 1

This will set every product_url to NULL which is currently not null.

UPDATE table_name
SET product_url = NULL
WHERE product_url is not null;
