This SQL statement provides correct syntax to generate the alias Annual Salary for the Calculated column SALARY*12. <br>
</p>
<p>
Incorrect Answers <br>
</p>
<p>
A: Alias can be surrounded with double quotation marks, not with single. Oracle error will be generated in this case. <br>
</p>
<p>
C: Alias needs to be surrounded with double quotation marks, it cannot just follow by the AS keyword. <br>
</p>
<p>
D: You cannot use any function as alias, so this SQL statement will fail. <br>
