Conventions<br />
Many examples of commands, SQL statements, and code are included throughout the<br />
book. Specific keywords are written in uppercase bold. For example: A NULL value<br />
represents an unknown state. Commands are shown in lowercase bold. For example: The<br />
dir command lists all files and subdirectories on Windows®. SQL statements are shown<br />
in upper case bold. For example: Use the SELECT statement to retrieve information from a<br />
table.<br />
Object names used in our examples are shown in bold italics. For example: The flights<br />
table has five columns.<br />
Italics are also used for variable names in the syntax of a command or statement. If the<br />
variable name has more than one word, it is joined <strong>with</strong> an underscore. For example:<br />
CREATE TABLE table_name<br />
