SQL with LOTR: Elven Wildcards

Deep within the fair realm of Lothlórien, you have been asked to create a shortlist of candidates for a recently vacated position on the council.

Of so many worthy elves, who to choose for such a lofty position? After much thought you decide to select candidates by name, which are often closely aligned to an elf's skill and temperament.

Choose those with tegil appearing anywhere in their first name, as they are likely to be good calligraphers, OR those with astar anywhere in their last name, who will be faithful to the role.

Elves table:

• firstname
• lastname

all names are in lowercase

To aid the scribes, return the firstname and lastname column concatenated, separated by a space, into a single shortlist column, and capitalise the first letter of each name.

 

 

Solution:

SELECT 
    INITCAP(firstname || ' ' || lastname) AS shortlist 
FROM 
    Elves 
WHERE 
    firstname LIKE '%tegil%' 
    OR lastname LIKE '%star%'

'INITCAP' converts the first letter of a word to uppercase.

 

 

 

Result:
