ROW number based on order of Insertion - response (3) by bala2121

Hi Vlad,
Thanks for your response. Will try that. Meanwhile, Is there any option to acheive the same thing within the scope of Row_number() function. I wanted to convert an existing sybase code into Teradata.
 
In sybase  'select rowid(a) from table1 as a' displays row number based on the order of insert. Will it work similarly in Teradata too? I tried but in vain. Is there any other option  that can be used along with Row_number() function to get the row number based on the order of insert.
 
Regards,
Bala.
