Sorting by number is not important, it was more a general question about
sequences of "variousnameXXX" and how to order them correctly with a simple
query.
Splitting in 2 fields seems the only way then. For the postcode it's just to
provide the user with an easy lookup table, but it's not *that* im
Hi,
yes, that would do, except that I don't know how many letters are in front
of the numbers.
And since they're not the same letters perhaps ORDER by 1,2 would have done
it perfectly, if only we could substring() intelligently first.

Thank you and Yes, separating the postcodes into field letters and numbers
may be the only way to be able to order a sequence like that:
CV1,CV2,..,CV10,..
It would also work since there could as many letters as needed
Anyone has a simple query for odering sequences correctly ?
Cheers,

What about:
select substring(code, 1, 1) as letter,
substring(code, 2, 2) + 0 as number
from epost
order by 2

| letter | number |
