>>>Alessio,
>>>I see. You might add columns on the fly though. ie:
>>>

>>>select *, ;
>>>  space(10) as myAddedStringColumn, ;
>>>  {/:} as myAddedDatetimeColumn ;
>>>  from myTable ;
>>>  where .f. ;
>>> into cursor crsMyCursor readwrite
>>>

>>>Array processing is generally faster but with these types of things it might not worth to test which one is really faster. However ALTER TABLE would have a problem. If you have longname field or add one with longname than next ... ADD COLUMN ... would error.
>>>I suggest 'Select ... where .F. ...'.
