Summary:
Timestamps are an alternative to using locks to prevent one process
from wiping out the updates of another process. Timestamps are used in
browse mode because locking would cause too many delays through
contention. The timestamp column is automatically updated by SQL
Server. The WHERE clause constructed by dbqual contains the comparison
necessary to prevent updates to rows that have been changed since they
were last read. Just decide how to let the user know that the value
has changed since it was last displayed.
