I think We can use average column a + average column (estimating), because of VARCHAR2 in our table, then we determine can determine how many records inside our database.
I think we can not ignore the overhead bit inside our tablespace, my Guru said leave 1 row space between PCT_USED and PCT_FREE I forgot to ask why. Sorry I am not good enough to help you, I have to go find my old notes.... sorry.

Dear Listers,

I've download a presentation talking about Calculating PCT_USED . the formula is quite simple :
PCT_USED + PCT_FREE < 100
PCT_USED = PCT_FREE + 1 row size

but I have no idea to calculate the size of 1 row in a table .

is there anyone who knows to calculate it ? or any alternative formula to calculate PCT_USED ?

Thanks a lot in advance : )
