INNER JOINS

[Former Member]

Hi,

I have a code to modify for its performance issues.

I found some queries in it containing FOR ALL ENTRIES and INNER JOIN .

Is it ok to blindly change these lines with something or some other reasons are there with the code for performance issues.

If something is to be done with FOR ALL ENTRIES, then please suggest an alternative for the following lines.

SELECT gpart vkont

INTO TABLE t_bpca

FROM fkkvkp

FOR ALL ENTRIES IN t_respart

WHERE gpart = t_respart-partner

AND opbuk NE c_siebel

AND vkpbz = 'AC'.

What is an alternative for INNER JOINS ?

You can check the below code -

SELECT BUKRS BELNR GJAHR AUGDT

FROM BSEG

INTO TABLE I_BSEG

WHERE BUKRS = ....

SELECT BUKRS BELNR BLART BLDAT

FROM BKPF

INTO TABLE I_BKPF

FOR ALL ENTRIES IN I_BSEG

WHERE BUKRS = I_BSEG-BUKRS

AND BELNR = I_BSEG-BELNR

AND BLDAT IN SO_BLDAT.

look another example

what is the use of FOR ALL ENTRIES

1. INNER JOIN

DBTAB1 <----

---

> DBTAB2

It is used to JOIN two DATABASE tables

having some COMMON fields.

2. Whereas

For All Entries,

DBTAB1 <----

---

> ITAB1

is not at all related to two DATABASE tables.

It is related to INTERNAL table.

3. If we want to fetch data

from some DBTABLE1

but we want to fetch

for only some records

which are contained in some internal table,

then we use for alll entries.

*----

1. simple example of for all entries.

2. NOTE THAT

In for all entries,

it is NOT necessary to use TWO DBTABLES.

(as against JOIN)

3. use this program (just copy paste)

it will fetch data

from T001

FOR ONLY TWO COMPANIES (as mentioned in itab)
