Learning Advanced SQL Queries
In previous lessons, you studied the most commonly used
commands. Of course, there are many more, and
you can find them in the SQL
Manual. When studying the manual, pay special
attention to the commands IN, MIN,
MAX, GROUP BY, CONCAT,
as well as functions for working with dates.
Study the SQL Manual. Try out individual commands in your code. Simultaneously, continue moving forward through the PHP Book.
