mySQL and MSSQL both have autonumber fields. You simply omit the key field
from the insert statement as the database auto inserts it.

INSERT INTO <table> (FieldOne, FieldTwo) VALUES ('Wibble', 'Wobble')
but
when selecting

SELECT KeyField, FieldOne, FieldTwo FROM myTable WHERE <whatever>
ORDER BY
<something>

Oracle is the only awkward one where you have to create a separate
"Sequence" and then insert Sequence.NextVal into you field you
are using as
a primary key.

INSERT INTO <table> (KeyField, FieldOne, FieldTwo) VALUES
(sequence.NextVal,
'Wibble', 'Wobble')


Another option which should work for any type of database is

INSERT INTO <table> (KeyField, FieldOne, FieldTwo) VALUES
(MAX(KeyField+1),
'Wibble', 'Wobble')

... if the above is total bo****ks in relation to this thread please feel
free to ignore it but it is just general database stuff.
