In the customers table there's an email column. Write a query that will retrieve all email addresses but will replace the @ symbol with <at> so they all look like andrew<at>teamtreehouse.com. Alias it as obfuscated_email .
My answer: SELECT REPLACE(<email>, <"@">, <at>) FROM <customers> AS "obfuscated_email"
I am not quite getting this. Can someone explain what I am doing wrong please

First of all, there are a few problems with the angle brackets
<>. The only purpose of the angle brackets in this query should be as a part of the string "<at>" that we're using to replace the "@" symbol. Everything other place in this query we don't need angle brackets.
In the REPLACE function:
- First argument: The column isn't called
<email>, it's just
- 2nd argument: we just want the
@symbol in parens
"@", not enclosed in angle brackets.
- 3rd argument: this is where we want the angle brackets, but the argument still needs to be wrapped in quotes because it's a string:
Also, the table name is just
<customers>. And we need to alias the column right after the WHERE function, not later.
SELECT REPLACE(email, "@", "<at>") AS "obfuscated_email" FROM customers;
