HI all.
I know u can set mysql to auto increment a column number (say an id for example)
but this involves creating a new row. Is it possible for the mysql to just have one row and keep incrementing that one number?

If not what are some solutions I could use. I need to have a unique number for certain uses in my site.

Thanks for any help.
wht if i don't know what the id has been incremented to?
then how can i find it and change it?
