HXTT DBF
How Rollback command works at HXTT
Norberto

I have a system running on Oracle Database, that makes some integration
with DBF's files.
What happens when, for an exception in the system, it send an order for a rollback at Oracle ??
There are different connection for Oracle and HXTT, and the rollback runs
on Oracle connection.

I notice that the records inserted on DBF files are marked as "Deleted"....

I just need to understand how does HXTT works in this case..

Thanks

>I notice that the records inserted on DBF files are marked as "Deleted"....
From Isolation Levels, you can see HXTT DBF supports all levels of Connection.TRANSACTION_READ_UNCOMMITTED, Connection.TRANSACTION_READ_COMMITTED,Connection.TRANSACTION_REPEATABLE_READ, and Connection.TRANSACTION_SERIALIZABLE .

With Read uncommitted level(Connection.TRANSACTION_READ_UNCOMMITTED), all rollbacked rows are visible in Xbase applicatons as deleted rows. If you won't to see those deleted rows. you should use Connection.TRANSACTION_READ_COMMITTED,Connection.TRANSACTION_REPEATABLE_READ, or Connection.TRANSACTION_SERIALIZABLE .
