I seem to be getting correct results but my answer is not being accepted as correct

What am i doing wrong in the code?

Question: Create a report from the customers table that shows their first initial of their first name and alias it as initial. Select their last name too. Type in your command below.

My answer:

select upper(substr(first_name, 1, 1)) || " " || last_name as "initial" from customers;

Hello Mazen,

Please provide your code & a link to the code challenge you're on. This can really help us to understand what is wrong in your code :)

Be careful about assuming your "correct" results are not being accepted. If you misunderstand the instructions, you will also be likely to misinterpret the results.

But just looking at your query, I have a few guesses:

  • are you sure this task involved concatenation?
  • is it possible that the alias "initial" was only intended to apply to the first character?
  • are you sure the task required you to apply upper-case conversion?

If I haven't guessed the issue, please provide the link to the challenge page for a more accurate analysis.

The thing that is driving me crazy is this error message that pops up Bummer! Expecting results like 'L Chalkley' not 'L Chalkley'.

Done I fixed it. After multiple attempts it seemed like it didn't want the first and last names concatenated. Oh well now I will continue my coding journey. Thank you for your support.

By the way one last question, if I already know HTML, CSS, JS & Java but I don't want to go through the whole courses again can I do something to earn the badges and points?

If you truly know the material, you can complete a course by taking just the quizzes and challenges. You'll get the badges and most of the points — all except the individual video points.
