[PERFORM] NUMERIC x VARCHAR

[Er Galvão Abbott]

Greetings. I have a question regarding performance of certain datatypes: I have a field where I will store my clients phone numbers. I know that this field will never exceed 15 characters, and I will store only numbers here (no dashes, dots, etc...), so I was wondering: Wich type is faster: NUMERIC(15,0) or VARCHAR(15)? Are there any storage differences between them? TIA, -- Er Galvão Abbott Desenvolvedor Web http://www.galvao.eti.br/ [EMAIL PROTECTED]
