    TCustomConnection.Open

    Makes the connection to the server.

    Declaration

    Source position: db.pas line 2268

    public 
procedure TCustomConnection.Open;

    Description

    Open establishes the connection with the server if it was not yet connected. Calling this method first triggers the BeforeConnect event. If an exception is raised during the execution of that event handler, the connect process is aborted. If LoginPrompt is True, the OnLogin event handler is called. Only after this event, the connection is actually established. After the connection was established, the AfterConnect event is triggered.

    Calling the Open method is equivalent to setting the Connected property to True.

    Errors

    If an exception is raised during the BeforeConnect or OnLogin handlers, the connection is not actually established.
