hi all,

i have another sorting problem.  i have data that
looks like...

sm2
sm101

i have a lot more data like this, but i want to keep
it simple.  the first two alphas represent an area and
the foloowing digit(s) represent a unique id.

the data is currently held in a text field.

i'm using (this is trimmed down)...

$sql_ipc_defect_code = 'SELECT code, code || \' - \'
|| description FROM defect ORDER BY LOWER(code) ASC';

this will list sm101 prior to sm2, which i think it
expected given my current order scheme.  but it isn't
what i want.

is there a way to sort this so that sm2 will come
before sm101?  do i need to change my data types?

tia...
