The information in this article applies to: - Microsoft SQL Server version 4.2 for OS/2 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.
