Answer / madhu t

if empno is a primary key then the records in table are
stored in ascending order of empno. hence we can use empno
< 5 to fetch the first 4 records of table.
There is also a standar query to fetch the first 10/100/200
records as below...
select empno,sal from emptble fetch first 100 rows only;

Answer / mr. cooooool

Hi.............

No. you cann't use this.
this query will display records less than 5.
not to for first 4 records.

For exm.
Suppose i have duplicate records like
Empno
1
2
1
1
3
4
then it display all the above records.
b'coz these all r less than 5.

Thanks.

I dont think records are stored in the sorted order of primary key in DB2. It happens only in VSAM!
