Hi,

I have following question?

Basically making a column type as Clob - instead of varchar2(4000) - how much extra overhead (as far as bytes/size) will it add to the table size?

I have a table with 6000 rows, and about 500 of them have 1 column with more that 4000 chars, so they need to go to a clob column. now I just want to know if I make a clob column and put the bigger column into clob for all the 6000 rows, how much disk space would I waste by doing this, or would Oracle use the space efficient enough on the clobs so that I shouldn't worry about size ? Other question is it true that Clobs are generally slower even the data in them are small ?

Thanks,
--Seema
