Subj:   Re: Format statement and floating point numbers
 
From:   John Hall

If the employee number is no larger than 15 digits, then you're back to concatenating 5 zeroes to satisfy the 20-digit requirement:

     sel '00000' || sth_employee_id (decimal(15,0), format '9(15)')
       from aeo_devlworkdb.flat_tlog
       where sth_employee_nbr is not null;

You won't need the CAST to DECIMAL if your sth_employee_id field contains the leading zeroes.

Once again, you can't use FLOAT (even as a CAST). The process of converting any value to a floating value will involve rounding errors for certain numeric values. You can imagine how popular your extract will be if the employee numbers aren't reliable (or accurate).
