MySQL Programming Question:

There are 4 SQL Data Definition Language (DDL) commands that are supported by "mysql". They are listed below with short descriptions:

► "CREATE dataObjectType dataObjectName" - Creates new databases, tables, views, triggers, indexes, and other data objects.
► "RENAME dataObjectType dataObjectName" - Renames existing databases, tables, views, triggers, indexes, and other data objects.
► "ALTER dataObjectType dataObjectName" - Alters properties of existing databases, tables, views, triggers, indexes, and other data objects.
► "DROP dataObjectType dataObjectName" - Drops existing databases, tables, views, triggers, indexes, and other data objects.

Here is a tutorial exercise of how to use DDL commands to create a database and a table:

>cd mysqlin
>mysql -u root

mysql> CREATE DATABASE ggl;
Query OK, 1 row affected (0.50 sec)

mysql> CREATE TABLE articles (name VARCHAR(80));
Query OK, 0 rows affected (0.25 sec)

mysql> DROP DATABASE ggl;
Query OK, 0 rows affected (0.41 sec)
