Issues understanding what is wrong with my code

Hello, I am having issues understanding what is wrong with this code. From my understanding i would assume this would be correct as i have renamed the column and have replaced the values as they need to be replaced based on the previous lessons. could i please get some help in understanding what is wrong with this code.

select email as obfuscated_email from customers where replace(email, "@", "<at>") = "<at>";

I have also tried the code

select replace(email, "@", "<at>") as obfuscated_email from customers where replace(email, "@", "<at>") = "<at>";

this code hasnt worked any better so i am unsure as to what is the problem

Since the instructions say to replace all email addresses, you are not filtering the results and won't need a WHERE clause here. And to modify the column content, call the function as part of the SELECT clause:

SELECT replace(email, "@", "<at>") AS obfuscated_email FROM customers;
