The only problem with this solution is that I have already incremented the sequence and need to use the current value?  Is there a way to assign the value to a variable and then use it in an insert statement?

This is just a hashed out example.  I am hoping it can all be done in sql statements...
Example:
        var num = select last_value from user_table_id_seq;

        insert into users ( "user_id", "user_fname", "user_lname", "user_email" )
        values ( 'num', 'Ray', 'Hunter', 'rhunter@enterasys.com' );

If I could do this is would be great...Is it possible?

Thanks,

I think you want to use nextval in this context. currval is used when you have already gotten a new sequence number and want to use it in several inserts in the same transaction.

If you make user_id a serial type, then its default value will be nextval and you could use: insert into users ( "user_fname", "user_lname", "user_email" )

  values ('Ray', 'Hunter', 'rhunter@enterasys.com' );
to add a row.
