Beginning SQL

SELECT MAX(LastName), MIN(LastName)
FROM MemberDetails
WHERE MemberId > 3;
Executing the code gives the results in the following table:
MAX(LastName) MIN(LastName)
Simons Botts
In the following SQL, the MAX() and MIN() functions have been removed, and executing the code will
show only the results set ordered using an ORDER BY clause
SELECT LastName
FROM MemberDetails
WHERE MemberId > 3
ORDER BY LastName;
You can see that MAX(LastName) is simply the last item in the list and MIN(LastName) is the first item
in the list:
LastName
Botts
Dales
Doors
Gee
Hawthorn
Hills
Jackson
Johnson
Jones
Jones
Night
Simons
Grouping and Aggregating Data
You can also see that generally ORDER BY, and therefore MAX() and MIN(), are based on alphabetical order,
although this isn’t always the case, especially when numbers and punctuation appear in strings. The next
Try It Out uses the MAX() and MIN() functions to gather birth dates for the film club’s chairperson.
