Question { 10739 }

what is the difference between FOR ALL ENTRIES and SELECT *
FROM ?

Answer

For all entries is used to join the one or more tables based on condition.Select * from is used to fetch the data from db
table,but don't use select * from due to performance standards. The code like this
select vbeln
erdat
ernam
vkorg from vbak into table it_vbak
where vbeln eq v_vbeln.
select vbeln
posnr
matnr
matkl from vbap into table it_vbap
for all entrie in it_vbak
where vbeln eq it_vbak-vbeln.

The sequence of fields used in select query must be same as
the sequence of fields in internal table.
