How can I select records from a DB table with intervals?

Question

Hello,
    Suppose my DB table is  having 20 lakh records. I need to fetch 50000(for eg, this number may change ) records intially then the next 50000 records and so on , so that I never get a runtime error "memory low".
I can select the first 50000 records using "select up to " statement but once i select the first 50000 records how can i fetch the remainning records as parts.
Please help.Urgent.

Hi,
Use packaze size statement in select statement.
EX: This is syntax.
SELECT ... INTO|APPENDING [CORRESPONDING FIELDS OF] TABLE <itab> [PACKAGE SIZE <n>] ...
1. If you want first 50000 records and do the required functionality with those and refresh the 50000 records and go for next 50000 means  use
SELECT CARRID CONNID
FROM   SPFLI
INTO   CORRESPONDING FIELDS OF TABLE ITAB
      PACKAGE SIZE 50000.
ENDSELECT.
2. If you want to append all records means
SELECT CARRID CONNID
FROM   SPFLI
INTO   APPENDING FIELDS OF TABLE ITAB
      PACKAGE SIZE 50000.
ENDSELECT.
