Easy....

select rownum+minlinenbr-1 from user_objects where rownum <= maxlinenbr-minlinenbr
minus
select linenbr from table

Replace the words with bind variables or whatever is appropriate for your application. Oh, and be sure to test it for accuracy - I'm typing without testing and could be "out by one" on some of the maths.

Regards,

Mark.

                      ORACLE-L

Hello Listers,

I need some SQL help.
Not sure if this is possible in plain SQL or not, but here it is: I have a table with two columns:
EMPNBR LINENBR
------ -------

   100         1
   200         4
   300         8
   400         9
   500        14

How would I find out the missing linenbrs (2,3,5,6,7) if I was given minlinenbr as 1 and
maxlinenbr as 10 that would be passed as variables (using &).

Thanks.

Kirti
