Need help with REPLACE function question (challenge task 1 of 1) in Reporting with SQL course.

Hi ,

I'm running into a problem with the REPLACE function challenge task in the Reporting with SQL course. Here's the question:

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 . Type in your command below.

I've experimented with it, but I can't solve this question. This is my query:

SELECT email AS obfuscated_email FROM customers WHERE REPLACE (email, "@", "<at>") = "<at>";

Here's the error message I received:

Bummer! Try again! I didn't receive any error message below my query (usually, you'll see a more specific message).

Any suggestions?

Thanks,

Jan

Hi Jan,

You don't need to have a WHERE condition here.

Instead of selecting the email column unaltered like you're currently doing, you can put your REPLACE function there.

This way, when it retrieves the email column it will do the replacement and you'll have the correct values you want for that column.

Hi Jason,

Thanks for the suggestion. Is this what you meant? Here's my new version of the query:

SELECT REPLACE(email, "@", "<at>") AS obfuscate_email FROM customers;

Unfortunately, I got the following error:

Bummer! Expecting results like Lauren.Chalkley<at>example.com not Lauren.Chalkley<at>example.com.

It listed a table below. The title was "obfuscate_email". Underneath the title, it listed a bunch of email addresses such as "Lauren.Chalkley<at>example.com".

I'm not sure what I"m missing. On the error message (starts with "Bummer! Expecting....), I'm not sure why it's repeating the same email address. The error message doesn't make any sense to me. Any ideas?

Thanks,

Jan

Yes that looks good except you have a small typo on the alias. It should be obfuscated_email

Unfortunately the error message wasn't helpful here.
