Re: SEQUENCES- How do I make use of them?

First of all sequence is not a table it is an object. They posses to pseudo columns with them
nextval and currval.

Select seq.nextval will give you the next higher value and
Select seq.currval will give you the current value of the sequence

You can generate a unique key for a table using sequence

e.g.
insert into dept(deptno) as select dept_seq.nextval from dept. Also using sql*ldr you can load the data into a table wth a unique key
