I know this was stated for V6 as well but when I actually looked at the data in the blocks, this was NOT the case. The trailing null columns each had the length indicator with value 0, not what I expected. Has anyone verified that this is working in Oracle 7 by actually looking at the data block? Does anyone know why V6 didn't do this?
