changing cases of a string

here is my code but seem not working:

SELECT first_name||UPPER(last_name)|| AS full_name, library_

This query code seems to be truncated, I assume "library_" was meant to be "library_id" but it is also missing a FROM clause.

But there's also two issues with the SELECT:

  • there's an extra concatenation operator between the field and the AS
  • the names need a space added to separate them

U need not to add || after last_name and use library_id instead of library_ Hope that help
