Unit:ZDbcGenericResolver. procedure TZGenericCachedResolver.

[DestinyR]

Code: Select all

procedure TZGenericCachedResolver.DefineCalcColumns(Columns: TObjectList;
  RowAccessor: TZRowAccessor);
var
  I: Integer;
begin
  for I := 1 to Metadata.GetColumnCount do
  begin
    if RowAccessor.IsNull(I) and (Metadata.GetTableName(I) <> '')
      and (Metadata.GetDefaultValue(I) <> '') then
    begin
      Columns.Add(TZResolverParameter.Create(I,
        Metadata.GetColumnName(I), Metadata.GetColumnType(I),
        True, Metadata.GetDefaultValue(I)));
    end;
  end;
end;

It is bug? Or why TableName used through ColumnCount.

Not 100% sure, but I believe this is just to make sure the tablename of the column is known before retrieiving a default value. If not, there's no way zeoslib can fill a column in the database anyway.
