TFloDataSource.CommitTran

This commits a new database transaction that you started with StartTransaction against the Data Definition. Any transactions you start with StartTransaction will need to be finalised by you with either CommitTran or RollbackTran.

Database transactions are handled automatically so you do not normally need to use this function unless you want specific control over database transactions.

Declaration: Function CommitTran : boolean

This example shows the relationship between CommitTran and RollbackTran.

procedure OnMapEvent(var Value:Variant);
begin
 //Check whether the transaction has started
 if Not Source.CommitTran then
 begin
 //If it fails to commit then you need to rollback
    LogError('Unable to commit transaction');
    Source.RollbackTran;
 end;
end;
