AutoNumber Issue

[Materialised]

Hi All,

I am writing a program in C, which will be driving via a MS Access database.
I am relitivly new to database design, so if anyone could help me with my
issue I would be greatful.
I have defined a database field to be a primary Key, this field is set to
contain the AutoNumber data type.
I would like to know if it is possible to start the autonumber sequence from
a number other than 0.

Thanks

You can also set the Seed of the Autoincrement column using ADOX if you use
a JET 4 database format.

This SQL will alter your column assuming the column meets the
requirements for autonumber and you are using JET 4.0.

"ALTER TABLE Table1 ALTER COLUMN ID Identity (200,10)"

Notes:

(200, 10) -> seed:200; increment:10
1. You must run the SQL from an OLEDB interface (ADO is a common OLEDB
interface; in Access one can use
Application.CurrentProject.Connection.Execute; DBengine and CurrentBD
are not part of an OLEDB interface);
2. If the table already has records numbered 1,2,3,4 etc, their
autonumber will not be changed (even if you remove the autonumber
column and start over);
3. the next record appended will have an autonumber of 200; if there
already is an autonumber of 200 then the append will fail (assuming a
primary key or not allow duplicates index).
