Hello

Lock in the cached update mode was added since ODAC 6.90.0.59 version. To lock records you should set the LockMode property to the lmLockImmediate or lmLockDelayed values.

Unique constrains in the cached update mode will be checked on storing records to database (on calling the ApplyUpdates method).
