Have you considered bulk loading the new data into a temp table and then

Rather than inserting an ancestor, why not define an interface
(this enforces implementation) and if there is a great level of
commonality you can implement it (the interface) by delegation in
your own 'subjobject' which is passed it's owner (as the base class)
at construction, easy to

Interesting, Mainly it was a practical method of making the ANSI join syntax
'scannable'
Mostly (like everybody I suspect) I use inner (or natural if MS SQL
supported them!)
so I can see the field's selected and the list of tables they are from, I'd
prob
use a more heavily indented style

also clearer if you use ansi join syntax (which we all should do), means if
you have any NULL
FK (ie project manager has not been appointed) you can use and OUTER join
SELECT
p.project_name, s.staff_name, m.staff_name
FROM
project p JOIN
staff s ON s.staff_id = s.staff_id JOIN

Have a look at this
http://www.delphizine.com/features/2000/04/di24rl_f/di24rl_f.asp
it uses rtti to converts enum sets to strings and back
so you could for TSomeTime = set of (stOne, stTwo, stThree),
var
SomeType: TSomeType;
SomeType := [stOne, stTwo]
Store it in the db as

BCD stores 2 decimal digits per byte (one in each nibble)
hence your 13 digit number fits in a 7 Byte BCD (with one nibble unused)
conversion would be rlatively simple assuming a byte (2 digit BCD) then
i := ord(b or 00FFH) + (10*ord(b shl 4))
