Hi,

If you want to insert duplicate entries you can do it by using the extension "ALLOW DUPLICATE ENTRIES" with the INSERT command.

If you want to identify the latest record after inserting the duplicate entries then you can check with the following possibility:

Insert 2 fields in the existing table structure:

1. Record Valid From

2. Record Valid To

When ever you insert a record mark the Valid From as the current date and Valid to as 31.12.9999...

After this when you want to insert a new record with same key fields....

for the first record change the Valid To date as current date

Insert new record with Valid from date = current date and Valid from date = 31.12.9999

Before inserting new record:

Record No. Key fields Valid From Date Valid To Date .....other fields

1 XXXXXXXXXXXXXXXXX 31.08.2008 31.12.9999 XXXXXXXXXXXXXXXXXXX

After Inserting new record

1 XXXXXXXXXXXXXXXXX 31.08.2008 17.09.2008 XXXXXXXXXXXXXXXXXXXX

2 XXXXXXXXXXXXXXXXX 17.09.2008 31.12.9999 XXXXXXXXXXXXXXXXXXXX

Hope this helps.

If a bespoke Z table then you can introduce extra "counter" or "duplicate" key field as you have seen.

By default the value 0 would be given to existing entries when you modify the table structure.

Whenever you attempt to insert a duplicate you would get an error, you would then increment the counter by 1 and retry. Failing that if you expect many duplicate entries it is better to do a SELECT MAX ( counter ) using the remaining table key before attempting an insert and incrementing the result by 1.

I've had to do this in the past. It is worth adding error handling for the event when your counter field hits the limit e.g. 99 for a 2 digit domain
