Description
Warning: PSStartTransaction is deprecated. Please use IProviderSupportNG.
Starts a transaction that encapsulates all activity until a call to PSEndTransaction.
The provider component applies updates within a transaction, if possible. To do so, it calls PSStartTransaction to start a transaction before applying updates, and calls PSEndTransaction when all updates are applied or too many errors are encountered.
Note: TDataSetProvider only starts a transaction (Using PSStartTransaction) if the PSInTransaction method indicates that there is no transaction already established. That is, it does not assume nested transaction support is available.
