How to fetch records between two seq uence numbers?

Question

We have thousands of records with seq uence numbers in the oracle database, we need to retrieve a number of records between two seq uence numbers, i.e. to retrieve records between 100 and 200 seq uence numbers. Could some one help me to find a query to fetch records.
I'll be waiting for your response..

Answer 1

Is this is what you are looking for?
SQL> create table tab1 (id number);
Table created.
SQL> insert into tab1 values (1);
1 row created.
SQL> insert into tab1 values (2);
1 row created.
SQL> insert into tab1 values (3);
1 row created.
SQL> commit;
Commit complete.
SQL> select * from tab1;
        ID
         1
         2
         3
SQL> select round(dbms_random.value(max(id)+1,max(id)+50)) random_number
  2  from tab1;
RANDOM_NUMBER
           43
SQL> select round(dbms_random.value(max(id)+1,max(id)+50)) random_number
  2  from tab1;
RANDOM_NUMBER
           39
SQL> select round(dbms_random.value(max(id)+1,max(id)+50)) random_number
  2  from tab1;
RANDOM_NUMBER
           13 This will generate a random number that will be greater then the maximum value in the table and lower then the maxvalue + 50. Having the range starting from maxvalue in the table you will never get a number generated which already exists in the table.
As you see in the above number genrated they are all between 4 and 53.
If you want to increase the range from where the number are generated just increase the value 50 that I used in the query.
