    Declaration

    Source position: db.pas line 1557

    public 
procedure TParams.CopyParamValuesFromDataset(ADataset: TDataSet; 
                                            CopyBound: Boolean);

    Description

    CopyParamValuesFromDataset assigns values to all parameters in the collection by searching in ADataset for fields with the same name, and assigning the value of the field to the Tparam instances using TParam.AssignField. By default, this operation is only performed on TParam instances with their Bound property set to False. If CopyBound is true, then the operation is performed on all TParam instances in the collection.

    Errors

    If, for some TParam instance, ADataset misses a field with the same name, an EDatabaseError exception will be raised.
