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,
