Subject int64 (numeric(18,0)) 64-bit numeric range
Author Kenneth Foo
Hi

How do I create a new column whose type is int64 and capable of handling
full 64-bit number range?

Numeric(18,0) handle values from 0 to 72057594037927936 (I think), giving me
a 56 bit range.
I need 64-bit for some kind of unique ID generation.

Thanks.

Regards
Ken
