NUMERIC x VARCHAR

<font face="Verdana">Greetings.<br /><br /> I have a question regarding performance of certain datatypes:<br /><br /> I
havea field where I will store my clients phone numbers. I know that this field will never exceed 15 characters, and I
willstore only numbers here (no dashes, dots, etc...), so I was wondering:<br /><br /> Wich type is faster:
NUMERIC(15,0)or VARCHAR(15)? Are there any storage differences between them?<br /><br /> TIA,<br /></font> <pre
