Hello, I want to use my SQL select statement to select a certain number of records within a range. For example, if I use the SQL statement

select * from mychildren.

I would get a resultset containing x amount of rows, say 2000.
Now my problem is that for my program retrieveing 2000 rows from a table is both memory and time consuming. Can I just choose from row 1 to 50. then decide to select from row 51 to 100 and the like. Is this possible in SQL.

If I select incrementally the program can run a lot faster. Thanks and please let me know if this is possible or other possible solutions.

Read about FETCH, it will be database dependent, but here you have link to DB2.
