TLiteConnection.StartTransaction Method

Begins a new user transaction.

Class

TLiteConnection

Syntax

procedure StartTransaction; overload; override;

Remarks

Call the StartTransaction method to begin a new user transaction against the database. Before calling StartTransaction, an application should check the status of the InTransaction property. If InTransaction is True, indicating that a transaction is already in progress, a subsequent call to StartTransaction without first calling Commit or Rollback to end the current transaction raises EDatabaseError. Calling StartTransaction when connection is closed also raises EDatabaseError. Updates, insertions, and deletions that take place after a call to StartTransaction are held by the database until an application calls Commit to save the changes, or Rollback to cancel them.
