Hi,

We are trying to replicate the way Oracle handles transaction isolation in
SAP-DB.

Our scenario is

- we have long transactions where large numbers of rows get loaded into
table(s).
- the consistency of these transactions across the tables is important.
- users query these tables constantly
- we want the user query to return data in the table ignoring any
transactions that may be in progress.
- we want the user query to return effectively immediately - ie not wait for
any transactions to complete or be rolled back.

What we have observed when trying different isolation levels is that
basically the user waits until the transaction(s) is/are complete, except if
we use the READ UNCOMMITTED option - which then returns data that we don't
the user to see.

Oracles behaviour is exactly what we want - essentially items in
transactions are hidden from users select statements.

Does anyone know if SAP-DB can mimic this behaviour.


Cheers
