Subject Re: RowLocation lifetime

Assuming row is not deleted, the question can only be answered
knowing the isolation level.  Basically the RowLocation can only
be counted on while a lock intent level lock is held on the table.
Intent table locks may be released as soon as a statement is
completed, or may be held to end of transaction depending on
the type of statement and type of isolation level.

The thing that may move an existing row in a heap are the compress
table system procedures.

If a row is deleted then there are other factors.
