[Keith]

Dear All,   Someone can help me to solve the below problems   1. I create a table for a period of time, there is huge records already posted. I would like to alter table and add serial primary key on that table.  It's impossible to add serial no by hand. Please adv  how can I add the serial number automatically.   2. Is there any library to translate digit number to English, I mean translate '1234' to 'one thousand two hundred thirty four'.. Pls help.   regards
