TCustomSQLDataSet.PSStartTransaction Method

Starts a transaction that encapsulates all activity until a call to PSEndTransaction.

Pascal

procedure PSStartTransaction; override;

C++

virtual __fastcall PSStartTransaction();

Description

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.
