Hi Paul,
In the case of mysql, it would be UUID and the value would look like this:
22ea1df1-3c40-11df-ab7a-200cd91e08cf
and the case of postgresql,
A0EEBC99-9C0B-4EF8-BB6D-6BB9BD380A11
{a0eebc99-9c0b-4ef8-bb6d-6bb9bd380a11}
a0eebc999c0b4ef8bb6d6bb9bd380a11
which is 36 CHAR length (including dashes not braces) and is not quite
like identity insert (autoincrement). You could store it as
binary(16) - in mysql - but you'll need to implement UDFs to convert
between binary & char. Is that what you're using? or Are you using an
INT type?

Tommy
