Hi Experts,

I'm trying to retreive the data from the tables with the fields TADIR(name,srcsystem,author),TRDIR(name,subc),TRDIRT(name,text) . For this i used join condition but here in trdir name is not a primary key so i'm getting error.

So how should i retrieve the data from these tables using joins.

Thanks in Advance,

Aadi.

Hi,

Do inner join using the following fields :

TADIR - OBJ_NAME

TRDIR - NAME

TRDIRT - NAME

Hi aditya,

once try with this code

tables : tadir, trdirt .

data: begin of itab occurs 0,

obj_name like tadir-OBJ_NAME,

SUBC like trdir-subc,

SPRSL like trdirt-sprsl,

end of itab.

select tadir_{obj_name trdir}subc trdirt~sprsl

from tadir

inner join trdir on trdir_{NAME = tadir}obj_name

inner join trdirt on trdirt_{name = trdir}NAME

into table itab

up to 10 rows.

loop at itab.

write 😕 itab-obj_name,

itab-subc,

itab-sprsl.

endloop.

Thanks & Regards,

object = 'PROG' AND

author IN s_author AND

srcsystem IN s_srcsys AND

devclass IN s_packag AND

( subc = '1' OR subc = 'M' OR subc = 'F' OR subc = 'S' OR subc = 'J'

Hi Aditya,

select table1_{column1 table1}column2

from table1

inner join table2 on table2_{column1 = table1}column1

where table1~column1 = 'abcd'.

You are getting errors because the 2 tables the same column name.

Hope this helps.

Hi,

Thanks for help but how should i join all the 3 tables.

You are showing with 2 tables but is that possible to join these 3 tables.

Please let me know as soon as possible.

Thanks in Advance,

Hi,

You can join

TADIR-OBJ_NAME with

TRDIR-NAME with

TRDIRT-NAME

all of them has language fields too...

For the table TADIR, i think the PGMID is always "R3TR"

OBJECT is "PROG"

Hope this helps.

This is an example code of joining 3 table.

Follow the same for your tables.

DATA: BEGIN OF wa,

carrid TYPE spfli-carrid,

connid TYPE spfli-connid,

fldate TYPE sflight-fldate,

bookid TYPE sbook-bookid,

END OF wa,

itab LIKE SORTED TABLE OF wa

WITH UNIQUE KEY carrid connid fldate bookid.

SELECT p_{carrid p}connid f_{fldate b}bookid

INTO CORRESPONDING FIELDS OF TABLE itab

FROM ( ( spfli AS p

INNER JOIN sflight AS f ON p_{carrid = f}carrid AND

p_{connid = f}connid )

INNER JOIN sbook AS b ON b_{carrid = f}carrid AND

b_{connid = f}connid AND

b_{fldate = f}fldate )

WHERE p~cityfrom = 'FRANKFURT' AND

p~cityto = 'NEW YORK' AND

f_{seatsmax > f}seatsocc.

LOOP AT itab INTO wa.

AT NEW fldate.

WRITE: / wa-carrid, wa-connid, wa-fldate.

ENDAT.

WRITE / wa-bookid.

ENDLOOP.

NOTE: All the key fields should be used to fetch right data.

Hi,

Thanks for your kind help but i my case trdir table with name field is not a key field so its giving me an error. In the table tadir, trdirt name is the key field.

I understand what you are trying to say but is it possible in my case with 3 tables having the same field (NAME) but in only 2 tables the field is declared as key field and in another tables it is not a key field

So how should i declare the join statement .

Please let me know the example using my code which i have posted.

Thanks in Advance,

Aadi.

TRDIR is a "Database view", its not an Database table.

Where as TRDIRT is a Table.

Join both tables on NAME field i.e, on a_{NAME = b}NAME, its enough.

Follow the above inner join post which i have sent.

Hi Adithya,

Fine but i require the fields from 3 tables like

TADIR--Name, srcsystem, Author.

TRDIR---Name, Subc,

TRDIRT---Name, Text(Short description)

Actually i developed using tadir and trdir using the above fields.

But now i want to add the Text( short description) of every object at output.

Actually the code was like this. I just want to add one more field i.e., TEXT which is present in TRDIRT.

So how should i write the code.

SELECT name subc author srcsystem devclass FROM

trdir INNER JOIN tadir ON tadir_{obj_name = trdir}name

INTO TABLE int_cust_program WHERE obj_name IN s_prog AND

object = 'PROG' AND

author IN s_author AND

srcsystem IN s_srcsys AND

devclass IN s_packag AND

( subc = '1' OR subc = 'M' OR subc = 'F' OR subc = 'S' OR subc = 'J'

or subc = 'K' OR subc = 'T' OR subc = 'X' or subc = 'I') "Changed by Aditya

AND

(

name LIKE 'Y%' OR

name LIKE 'Z%' OR

name LIKE 'LY%' OR

name LIKE 'LZ%'

Re: Joins

Former Member — Fri, 23 May 2008 16:13:58 GMT

select a_{name a}text b_{srcsystem b}author c~subc

INTO CORRESPONDING FIELDS OF TABLE int_cust_program

FROM ( ( trdirt AS a

INNER JOIN tadir AS b ON a_{name = b}obj_name AND

a_{sprsl = b}masterlang )

INNER JOIN trdir AS c ON a_{name = c}name )

WHERE b~obj_name IN s_prog

AND b~object = 'PROG'

AND b~author IN s_author

AND b~srcsystem IN s_srcsys

AND b~devclass IN s_packag

AND ( c_{subc = '1' OR c}subc = 'M' OR c_{subc = 'F' OR c}subc = 'S' OR c_{subc = 'J' or c}subc = 'K' OR c_{subc = 'T' OR c}subc = 'X' or c~subc = 'I')

AND (

a~name LIKE 'Y%' OR

a~name LIKE 'Z%' OR

a~name LIKE 'LY%' OR

a~name LIKE 'LZ%'
