Want to Avoid Loop for all entries with select query !!

Question

Hi Guru's  !
This is my following code . I want to avoid loop  to improve the performance of program.
data: lt_cuhd type HASHED TABLE OF /sapsll/cuhd WITH UNIQUE key guid_cuhd,
      ls_cuhd type /sapsll/cuhd.
data: lt_comments type STANDARD TABLE OF zss_comments,
      ls_comments type zss_comments.
data: lv_objkey type string.
select * from /sapsll/cuhd into table lt_cuhd.
loop at lt_cuhd  into ls_cuhd.
  CONCATENATE ls_cuhd-corder '%' into lv_objkey. " Example 'Mum%'
  select * from zss_comments into table lt_comments
            where objkey like lv_objkey
             AND guid_cuhd = ls_cuhd-guid_cuhd
              AND event_id <> ''.
endloop.
I want
New code should be...using all entries no loop required.
  *select * from zss_comments into table lt_comments
            where objkey like lv_objkey
             AND guid_cuhd = ls_cuhd-guid_cuhd
              AND event_id <> ''.*

Answer 1

why dont you add the object key also to  lt_cuhd and once you fetch the data to lt_cuhd loop it and add the '%'
when looping use field symbols so that you dont have to use  modify.
then use for all entries using lt_cuhd
i don't you can find a better way to add the % mark apart from looping but by this way only one select query will be done for
zss_comments
Thanks
