Indicates whether actions against the dataset occur in the context of a transaction.
function PSInTransaction: Boolean; override;
virtual __fastcall Boolean PSInTransaction();
The provider component applies updates within a transaction, if possible. To do so, it first checks whether a transaction is already underway, and if not, generates one using PSStartTransaction. To determine whether a transaction is already underway, the provider calls PSInTransaction.
PSInTransaction returns true if there is a transaction underway, and false otherwise.
