Using Sequence to populate ID(SOLVED)

I have never used sequences in pl sql before, so I am just wondering if it is best practice to use seq.nextval or seq.currval?

I do not know if using .currval will use the current number, and then the next time it is used ti will use the next number in line, or if .currval will keep using the same number over and over again.

Thanks for any advice

edit - I know I can easily answer this question by testing it out, but I am also looking for any best practice tips for using sequences since I have never used one.

you have to use nextval to retrieve the unique sequence value.

After that, curval will return the value created by that nextval call.

curval only works after you have called nextval.
