Sets the lock bias for the PSQL operation specified in the VAOperation property of the VACommand control.

PSQL supports both single and multiple record locking. If record locking is used, a record is locked when it is read. The VALockBias property has no effect if Open, Close, Insert, Update, or Delete operations are specified in the VAOperation property.

Single record locks are released whenever another record is read, or a record is inserted, updated, or deleted. Multiple record locks may be released on individual records or on all locked records by invoking the Unlock method for the control.
