Description
Indicates whether actions against the dataset occur in the context of a transaction.
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.
This method is an implementation of the IProviderSupport.PSInTransaction method and, by default, returns False, because TDataSet does not implement a provider by default. To use it, every TDataSet descendant must override it in its specific way.
