mmm it is set as secondary key! i thought it was clear from what jonathan said!..and for your kind information i do know what 'm speaking about! i didnt see the table clearly before! but when i did, i just saw john’s post so thought snam will be knowing i made a mistake!
And david, i know you are experienced in this field and i respect that, but that doesnt give you the right to criticize others for their lack of knowledge! if you know and are willing to help then that fine! thank you! but dont be rude to others!
you have already made funny of me in my previous post! and the first time i posted you were really rude to me saying that i shouldnt use short forms! but i just mended my ways and 'm using full forms now! so you can try being gentle once a while!
