Good clarification. Any downside to using an auto increment number?
```
fiKeyID INTEGER GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY
```

It is a field you create. Which is why I wrote "Where is the
table in question, and is a suitable column (eg a timestamp)
to determine what the newest record
Is a field I create, or is it part of all records?

Yes, you do
One table contains history. The old history is never replaced. New
history is added. What is relevant is the most recent history. Is there a
way to find the newest records without the KeyID?

That depends on what you're trying to achieve,
I added the KeyID so I could sort from newest to oldest. Was it necessary
to add this KeyID, or is there another way to find the newest records
without the KeyID?

Marcin, Minor tweak => works! I also added DESC to retrieve the newest
records using the field key name (number is an auto increment).
`
"SELECT FIRST " + stNumOfRecordsToRetrieve + " * FROM " + stTableName +
" ORDER BY " + fstKeyID + " DESC";
`
