Reporting with SQL - Challenge Task 2 of 2

https://teamtreehouse.com/library/reporting-with-sql/working-with-text/changing-cases-of-strings

Im being asked to select a first_name, last_name and library_id from a database. The first_name and last_name are aliased to a single column. My solution is below:

> select first_name || " " || upper(last_name) as full_name, library_id as libary_id from patrons;

full_name   libary_id
Andrew CHALKLEY MCL1001
Dave MCFARLAND  MCL1010
Alena HOLLIGAN  MCL1100
Michael POLEY   MCL1011

That appears to be the exact output they want, but my solution is not correct.

Any help would be appreciated, Chris

You just have a typo/misspelling.

You wrote "libary_id" (just one "r") instead of "library_id" (two "r"s) for the last alias.

But you don't really need an alias there at all since that's the column name.
