SELECT DISTINCT with JOIN

Hi,
how Do I write this select in rigth way in ABAP
SELECT ska1ktopl AS ktopl ska1saknr AS saknr
    t370k_t~eartx AS eartx
    INTO TABLE lt_ska1 FROM ska1
    JOIN (SELECT DISTINCT damage_gl FROM zzpm_cost_elem ) ON ska1saknr = zzpm_cost_elemdamage_gl.
The problem with the select "SELECT DISTINCT damage_gl FROM zzpm_cost_elem " which I have to put table name instead of it
What should I do ?
Thx

Hi Friend ,
Please see this example how you can use the select DISTINCT statement
DATA: ITAB TYPE STANDARD TABLE OF SPFLI,
      WA LIKE LINE OF ITAB.
DATA: LINE(72) TYPE C,
      LIST LIKE TABLE OF LINE(72).
LINE = ' CITYFROM CITYTO '.
APPEND LINE TO LIST.
SELECT DISTINCT (LIST)
       INTO CORRESPONDING FIELDS OF TABLE ITAB
       FROM SPFLI.
IF SY-SUBRC EQ 0.
LOOP AT ITAB INTO WA.
    WRITE: / WA-CITYFROM, WA-CITYTO.
ENDLOOP.
ENDIF.

Need help with select distinct with group by

I am trying achieve having a select distinct with a order by and after looking on the internet and trying different examples, I have been unsucessful.

Select Distinct and join in ODI

Hi,
I have following task to perform: I am loading metadata into Planning dimension from Oracle database. I have two tables
1. "Sales"
Columns: Name, Number, Value
Sample Data:
Product 1, 10, 200
Product 2, 30, 100,
Product 1, 15, 500
2. P&R
Columns:
Name, Alias
Product 1, SampleSoda1
Product 2, SampleSoda2,
Resource 1, CanForSoda,
Resource 2, CO2
What I need to do is: I have to select name and alias from second table of all products that were sold.
So I need to select distinct Name from Table 1, naxt join it with Table 2 (so I have Name and Alias) and load it to planning.
I am a little confused how to do it.
Any help would be great!
Best regards,
Greg

Hi Greg,
What you can do is either :
- Create a yellow interface with your table Sales as source. Map the name column directly in the target. In the flow tab, click on your target and select "Distinct rows".
- Create a second interface, with your first interface as source. Select the "Use Temporary Interface as Derived Table (Sub-Select)" checkbox.
- Add your second datastore and join it. Or you can use a lookup table.
OR
- Create an interface with Sales and P&R as source (or set P&R as a lookup table).
- Go on the flow tab and select "Distinct rows".
If you've a lot a data in the first table, I would go for the first solution.
Hope it helps.

JeromeFr

SELECT DISTINCT With OPEN cursor FOR

Hello.
I have the following procedure. All it does is open a cursor for an SQL string passed into it, and return the open cursor.
PROCEDURE sp_execute_dynamic (hold_input_string IN CLOB,
hold_cursor OUT hold_cursor_type) IS
BEGIN
OPEN hold_cursor FOR TO_CHAR(hold_input_string);
END sp_execute_dynamic;
It works fine except when I perform SELECT DISTINCT. I get the following error.
SQL> declare
2 TYPE hold_cursor_type IS REF CURSOR;
3 hold_cursor hold_cursor_type;
4 hold_object_name VARCHAR2(1024);
5 hold_object_type VARCHAR2(1024);
6 begin
7 dynamic_sql_pkg.sp_execute_dynamic('select distinct object_name from user_objects where object_
name in (''PLAN_TABLE'',''DBA_OBJECTS'')',hold_cursor);
8 loop
9 fetch hold_cursor into hold_object_name, hold_object_type;
10 exit when hold_cursor%NOTFOUND;
11 dbms_output.put_line('Object Name = '||hold_object_name||' Object Type = '||hold_object_type);
12 end loop;
13 end;
14 /
declare
ERROR at line 1:
ORA-01007: variable not in select list
ORA-06512: at line 9
It does the same thing with SELECT UNIQUE or SELECT with a GROUP BY. Can anyone tell me why this happens and what I could to to work around it?
Thanks
Chris

see at line 7 you are selecting only one column and at line 9you are fetching into two variables
7 dynamic_sql_pkg.sp_execute_dynamic('select distinct object_name from user_objects where object_
name in (''PLAN_TABLE'',''DBA_OBJECTS'')',hold_cursor);
8 loop
9 fetch hold_cursor into hold_object_name, hold_object_type;

SELECT DISTINCT with LINQ

Hey,
I am trying to perform a SELECT DISTINCT COL1, COL2, COL3 FROM VIEW WHERE CONDITION using LINQ with ODAC 112030 but I get different results.
C#:
var s1 = context.Select(v=>new { v.COL1, v.COL2, v.COL3}).Where(...).Distinct();
Any ideas?

Hey,
I think this way works - with anonymous types:
context.Entity.Where(...).Select(ent => new { col1 = ent.COL1, ... }).Distinct();.
You can also do context.Entity.Select("distinct it.COL1, it.COL2").Where("..."); but one should be careful to add all necessary columns in select statement.

If I run it without a where clause at all I get some values repeat itself up to 4 times. Does anyone have a clue what is wrong with my query?

You are joining a parent table (OBJEKTI) with three child tables (the other three: PON, TEH, OPR).
Whenever you do that, you will always get duplication of child-rows, if there are multiple child-rows for a parent-row in any of the three child tables.
For example, let P be a parent table, with two child tables, say C1 and C2.
Contents:
Table P:
p1
Table C1 (has two rows for row p1):
1 p1
2 p1
Table C2 (has three rows for row p1):
10 p1
20 p1
30 p1If you now do this:
select P.*,C1.*,C2.*
from P, C1, C2
where [join P with C1] and [join P with C2]Then your result set will look like this:
P.p1 C1.1 C1.p1 C2.10 C2.p1
P.p1 C1.1 C1.p1 C2.20 C2.p1
P.p1 C1.1 C1.p1 C2.30 C2.p1
P.p1 C1.2 C1.p1 C2.10 C2.p1
P.p1 C1.2 C1.p1 C2.20 C2.p1
P.p1 C1.2 C1.p1 C2.30 C2.p1As you can see every C1 row is duplicated three times in the resultset (due to join with C2).
And every C2 row is duplicated two times in the resultset (due to join with C1).
This is simply what happens if you join a parent table with multiple child tables...
Question now is: what is the expected result that you are looking for?

Help! Howto use the join function in a query with select distinct ?

Hi!
I have 2 tables. I want to select only 1 painting of each artists.
select distinct idartist
from tbl_artworks
where blah blah blah
order by rand()
how does the "join" function work for add: name, lastname, title, image and much more... i try... but i fail...
tbl_artists
idartist
name
lastname
1
Paul
Gaugain
2
Vincent
Van Gogh
3
Pablo
Picasso
tbl_artworks
idartwork
idartist
title
image

sunflower
image2.jpg
3
3
Dora maar au chat
image3.jpg
4
2
Sky
image4.jpg
5
3
La vie
image5.jpg

Getting a single random image for each probably requires a combination of sql and cf. It would take someone smarter than me to do it with sql alone. I would probably try something like this:
1. Run a database query that gets all the images from all the artists.
2. Run a Q of Q that gets a distinct list of artist ids.
3. Loop through that list and run a Q of Q to get all the images for that artist.
4. Still in that loop, use randrange (1 to the recordcount) to select a random record from your Q of Q

Select distinct problem with muliple join tables, help needed

Hi,
I have two main tables. Each has its of sub joined tables.
guest_id_for_reservation connects two major tables. This has
to be that way
because my guest may change the room status from single to
double (and the
similar exceptional requests).
guests reservation
guest_id_for_reservation
countrytable hoteltable
delegationtable roomtype
I form a query. I want to select distinct those results. But
it does not
work.
If I do not include any table related to reservation table
and its sub
joined tables (disregarding guest_id_for_reservation), it
works.
Is there a specific syntax for select distinct of this type
or any
workaround.?
Thank you
Hakan

Hi I'm still battling with this - have connected the AX to my Imac via ethernet and it shows up fine in Airport Utility. Status light is green and it says its set up to connect to my existing wireless network using wireless connection. Security in Network Preferences is the same for both: WPA2 Personal.
So I don't think there's a problem with the AX, and my current wireless network (BT Home Hub) is working fine.
And when I restore factory settings Airport Utility can see the AX before updating settings so the wireless side of AX must work too.
I'm figuring it must be something about the settings that mean AU can't see it anymore. But I can't work out what, since security is the same.
Any ideas would be great!

Ambigious Column Not Detected In SELECT with JOIN

I wrote the following SELECT query.
SELECT TRANS.ID, TRANS.INVISIBLE
FROM TRANS
JOIN TRANSCAT TC ON TC.ID = TRANS.TRANSCATID
JOIN TRANSTYPE TT ON TT.ID = TRANS.TRANSTYPEID
WHERE INVISIBLE = 0
AND ID IN (SELECT DISTINCT TRANSID FROM XTRANS WHERE XTRANS.DESCR LIKE '%Geri%' )
The four table are as follows.
CREATE TABLE "DBO"."TRANSCAT"

     "NAME" VARCHAR2(16 CHAR),
     CONSTRAINT "pTransCat" PRIMARY KEY ("ID") ENABLE NOVALIDATE

     "NAME" VARCHAR2(16 CHAR),
     "MESSAGE" NUMBER(1,0) NOT NULL ENABLE,
     CONSTRAINT "pTransType" PRIMARY KEY ("ID") ENABLE NOVALIDATE
CREATE TABLE "DBO"."TRANS"

     "REFERENCE" NUMBER(10,0) NOT NULL ENABLE,
     "TRANSCATID" NUMBER(19,0) NOT NULL ENABLE,
     "NAME" VARCHAR2(48 CHAR),
     "TRANSTYPEID" NUMBER(19,0) NOT NULL ENABLE,
     "SIZE" VARCHAR2(8 CHAR),
     "KEYWORD" VARCHAR2(64 CHAR),
     "PARAMCOUNT" NUMBER(3,0) NOT NULL ENABLE,
     "PARAMHELP" CLOB,
     "INVISIBLE" NUMBER(1,0) NOT NULL ENABLE,
     "SELECTFLAG" NUMBER(1,0) NOT NULL ENABLE,
     "STAMP" NUMBER(5,0) NOT NULL ENABLE,
     CONSTRAINT "pTrans" PRIMARY KEY ("ID") ENABLE NOVALIDATE,
     CONSTRAINT "fTrans_TransCatId" FOREIGN KEY ("TRANSCATID")
     REFERENCES "DBO"."TRANSCAT" ("ID") ENABLE,
     CONSTRAINT "fTrans_TransTypeId" FOREIGN KEY ("TRANSTYPEID")
     REFERENCES "DBO"."TRANSTYPE" ("ID") ENABLE
CREATE TABLE "DBO"."XTRANS"
(     "ID" NUMBER(19,0) NOT NULL ENABLE,
     "TRANSID" NUMBER(19,0) NOT NULL ENABLE,

     REFERENCES "DBO"."TRANS" ("ID") ENABLE
CREATE UNIQUE INDEX "DBO"."uXTrans_TransId_LanguageId" ON "DBO"."XTRANS" ("TRANSID", "LANGUAGEID") ;
As you can see every table has an ID column as primary key. When I run this query in SQLDeveloper, the result was zero rows. In the detail plan, Oracle seems to match TransId column of XTrans with TransType's Id column.
I am new to Oracle. In Sql Server 2005 i get an ambigious column error. Why doesn't Oracle give such an error? Is this a bug?

My intention is to match XTRANS.TRANSID with TRANS.ID not TRANSTYPE.ID. But oracle matches it with TRANSTYPE.ID. Also TRANSTYPE is not in the FROM clause, why is it the default table? I couldn't understand.
As you said, I get the expected error with following SELECT
SELECT TRANS.ID, TRANS.INVISIBLE
FROM TRANS, TRANSCAT TC, TRANSTYPE TT
WHERE INVISIBLE = 0
AND TC.ID = TRANS.TRANSCATID
AND TT.ID = TRANS.TRANSTYPEID
AND ID IN (SELECT DISTINCT TRANSID FROM XTRANS WHERE XTRANS.DESCR LIKE '%Geri%' )

Dynamic select list with display,return val & join condition issue.

hello,
I am having a dynamic select list with display, return value
say for example my select statement is
select distinct dname d, deptno r
from dept dt
right join emp e on (e.deptno=dt.deptno)
where (condition)
when i tried this query for my select list, it is not working. It saying that
" LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query. "
I am not able to understand the problem. Can anyone help me out with this issue?
thanks.

Shouldn't your join have dept as the driving table?
select distinct dname d, deptno r
from dept dt
right join emp e on (dt.deptno = e.deptno)
where (condition)
Or using older Oracle standard join
select distinct dname d, deptno r
from dept dt, emp e
where (dt.deptno (+) = e.deptno) AND (OTHER WHERE condition)
OR
(Since a right join is just getting the values from the driving table that are NOT in the associated table)
select distinct dname d, deptno r
from dept dt
WHERE dt deptno NOT IN (SELECT deptno FROM emp) AND (OTHER where condition)
Thank you,

Absolute dynamic select query with dynamic join and where

Has anyone ever tried creating an absolutely dynamic SELECT query with dynamic Join and Where conditions.
I have a requirement of creating such a query in an Utility Class, and i have written the code. But its throwing my sysntax errors.
Please let me know where am I going wrong OR is it really possible to create such a dynamic Query??
    SELECT (FIELDS) INTO TABLE IT_TABLES
      FROM ( (ME->TABLE1) inner join ( me->table2 )
      on ( on_condition ) )
      WHERE (me->where_fields).
Ags.

It worked for me in a following way:
select * into corresponding fields of table <result_table>
        from (join_string)
        where (l_where).
Where the contents of join_string were dynamically build using concatenation. So it will be something like
concatenate ME->TABLE1 'as a INNER JOIN' me->table2 'as b ON (' into join_string separated by space.
<...>
add here matching/reference colums, something like
concatenate 'a~' me->TABLE1_JOIN_COL into temp1.
concatenate 'b~' me->TABLE2_JOIN_COL into temp2.
concatenate join_string temp1 '=' temp2 into join_string separated by space.
<...>
concatenate join_string ')' into join_string separated by space.
And then use similar approach for l_where variable.

SELECT Query design with JOINS

Dear Users,
In one of our requirements, we have a SELECT query which joins a few tables together and selects a few fields from each table.
Example: Fields 1,2 and 3 from Table 1
Fields 4 and 5 from Table 2.
These fields are later displayed in the form of an ALV. However, the end user wants more fields on the output, let's say field 6 from Table 2. Due to this requirement, I have to amend the SELECT query to add field 6 of Table 2.
The above example is simple since it only involves 2 tables. However, in reality, we have a SELECT query with INNER JOINS on more than 6 tables and we don't want to change the code when someone asks for an additional field from one of these tables. Is there any way by which I can design my SELECT query (Using field symbols or dynamic selections etc) such that I don't have to amend the SELECT query and instead I should be able to maintain the field required by the user and it's source table name in a Z-Table and the SELECT automatically picks it up ? Thanks!
Vijay

better you can create a view on your 6 or more tables and select the fields .
Use Select * from <view name> every time in a select statement.
If you need a additional column then just change the view , there is no need to change of your select query.
with regards

ODI: Way to select Distinct data while doing Join of tables at Source

HI,
Our requirement is to do a join on multiple tables selecting distinct data from those table at source.
But we are not able to see the Distinct Box in flow tab.
Any thoughts to resolve our problem
Pratik

You can not put DISTINCT clause selectively .
If you choose to opt for DISTINCT then Oracle will apply the distinct to all columns present in the select list .
So at your IKM level just click the distinct check box .. run your interface and find out the query generated .
See if your requirement is getting fullfilled or not .
Thank,
