Summary
In this lesson, you learned several new SQL statements. CREATE TABLE is used to create new tables, ALTER TABLE is used to change table columns (or other objects like constraints or indexes), and DROP TABLE is used to completely delete a table. These statements should be used with extreme caution, and only after backups have been made. As the exact syntax of each of these statements varies from one DBMS to another, you should consult your own DBMS documentation for more information.
