well.thanks.that's nice.
but i want to do in the simple pl.sql block.
I will get the user input like '10,21,6,11,19,3'
then i will rearrange the same as 3,6,10,11,19,21
something like this.I will part this series
in return.I really thank you for your approach.
But if u could try only with pl.sql
block not going for a procedure.Is it really
possible to do what i really want.
Hope u can understand what i am asking.
thanks for the help.
