Why?

Because as I said above that rowset for the euro1 area is perfect because in the location column there are lines for the euro1, SUBAREA1 and SUBAREA2 area. is exists, whereas if we see that there are no lines for AREA2 with the value SUBAREA2 in the place, even regarding the Domain3, there is no line that has the value of the SUBAREA1 location and even for AREA4, there is no line as location = AREA4. It is a table which is having all the names of place with nested values; for example, we can see that vill7 is exist in zone2 including SUBAREA1 (COLUMN NAME) = "SUBAREA1" AND SUBAREA2 (COLUMN NAME) = "SUBAREA2", but I would like to know location = SUBAREA2 then it will say no line, I want to generate all the lines that is to have no value in the column location for said AREA/SUBAREA1/SUBAREA2 column. Table is sorted by ID. Total column lines are 45800.

SQL> select * from vill where area='AREA1' and location='SUBAREA1';

        ID AREA                 SUBAREA1             SUBAREA2             LOCATION
---------- -------------------- -------------------- -------------------- --------------------
         2 AREA1                SUBAREA1             SUBAREA2             SUBAREA1

SQL> select * from vill where area='AREA2' and location='SUBAREA1';

        ID AREA                 SUBAREA1             SUBAREA2             LOCATION
---------- -------------------- -------------------- -------------------- --------------------
         9 AREA2                SUBAREA1             SUBAREA2             SUBAREA1

It is also ok, but if said

SQL> select * from vill where area='AREA2' and location='SUBAREA2';

no rows selected

< <-Yes, this line I want to generate, because there should be a line whose location = "SBUAREA2" but why? Because otherwise how do I know what is the hierarchy of the SUBAREA2; While vill 5,6,7 and 8 were SUBAREA2 as "SUBAREA2".

I'm not sure how I am clear in my question, please let me know if I need to provide more details.

Thank you.

Sorry, I don't understand that one line. Was it a mistake? I think I understand all the other lines that you want to, but I do not understand why you want the one above. Did you mean

ID AREA                 SUBAREA1             SUBAREA2             LOCATION
---------- -------------------- -------------------- -------------------- --------------------
131 my state             my city              street 2             street 2

If this is not the case, why you don't want the row immediately above? Why don't you also:

`       ID AREA                 SUBAREA1             SUBAREA2             LOCATION
---------- -------------------- -------------------- -------------------- --------------------
       131 my state             new city             new city             street 2

Assuming it was just a mistake, the following Gets the results you want

WITH     rows_needed     AS
(
     SELECT     area
     ,     area          AS subarea1
     ,     area          AS subarea2
     ,     area          AS location
     FROM     vill
     WHERE     area           != subarea1
     OR     area          != subarea2
     OR     area          != location
    UNION
     SELECT     area
     ,     subarea1
     ,     subarea1     AS subarea2
     ,     subarea1     AS location
     FROM     vill
     WHERE     subarea1     != subarea2
     OR     subarea1     != location
    UNION
     SELECT     area
     ,     subarea1
     ,     subarea2
     ,     subarea2     AS location
     FROM     vill
)
SELECT     (
          SELECT     MAX (id)
          FROM     vill
     ) + ROWNUM          AS id
,     area, subarea1, subarea2, location
FROM     rows_needed
WHERE     (area, subarea1, subarea2, location)
           NOT IN (
                   SELECT  area, subarea1, subarea2, location
                   FROM    vill
                 )
;

except that it is for an indefinite period including the ID will assign to what line. I guess that doesn't matter, as long as 130 to 137 numbers are used (or 131 to 138, if that is what you really want).

When I run your code on the table he returned me the desired output, but when I run it on my actual table that is having 45800 lines, then he messed up some results, because I think that in your code, I should mention the clause ORDER BY ID somewhere... Therefore, in this example I mention different IDS while inserting the lines. Your code worked very well because it is having only 25 rows with ID Ordered, while my actual table is to have 45800 lines in the table, there is no guarantee of ID ordered... so I think that its a problem with the order by clause, ID... but I don't know where I should put this clause

What is the significance of id? Is this just a unique key? That's, I guess that each line must have an id and two rows can have the same id, but, aside from that, it doesn't matter what line has which id.
The query I posted yesterday assumes that subarea1 and subarea2 were functionally dependent on the area. as in the example of data you posted yesterday. I see your last post that's not true, and which explains erroneous results.

As I said yesterday, if you are actually setting up new lines in the table, you must use a sequence to generate identifiers.
