Which isolation level will allow application A to immediately read the committed value of a row that is exclusively locked by application B?
Suggested Answer:
A
Read stability (RS) locks only those rows that an application retrieves within a unit of work. It ensures that any qualifying row read during a unit of work is not changed by other application processes until the unit of work completes, and that any row changed by another application process is not read until the change is committed by that process
