What is the datatype to be used
for Primary Key columns for most
optimised access given that
- There will be a single column primary key only
- The values will only be integers (but as
strings) at least 12 digits (characters) long
- all positions will be occupied (no leading 0's)
- Tables may have upto 1m+ rows

Hi folks,
I've got a program which has a function which uses templates to accept
parameters of any type.
Works well, but there's one certain datatype which I want to special case
and do an extra thing to. The datatype is a class I made.
Is there anyway for me to test a parameters datatype in a template using
function?
