Hello all,
I am new at SQL Server 2005 and have been reading everything I canfind
about the new optimistic concurrency control mechanisms. As far as I
can tell, the Snapshot Isolation Level is based avoids the use of
shared locks using rowversioning instead.
To control rowversions in SQL Server 2000 I was using an extra column
in each table containing a rowversion datatype. What i do with this is
find out if a row was modified. Is it possible in SQL Server 2005 to
avoid the use of this extra column, using the new versioning features?
What I mean is, if the Snapshot Isolation already manages rowversions
in TempDB, is it possible for me to query those versions using some
stored procedures or functions given by SQL Server 2005 system? What
functionalities does SQL Server 2005 gives me for that (any
documentation pointer would help)?
This would allow me to do the exact same processing that i was doing
with the rowversion column in SQL Server 2000 without the need for
that extra column.
For all of you my thanks and best wishes
Susana Guedes
