Hi again,
Sorry for delay.
Guillaume, I read your answer for first question but It's not clear to me. The table has a column and index also use that column. so in that example, I think table size and index size should be equal. Why these are not equal?
Your answer for second question is pretty clear. Thanks for your both of answers.
Steven, thanks for your response. I got a new information thanks to you.
Regards,
Gunce Kaya
