Inner join driving table

Hi,
we have 2 dimension tables and 1 fact table. So our physical query looks like the below:
Select a, b, c....
from
BC_CTR T89740,
M_CTR T49296,
BC_M_FCT T59920
where
T49296.CTR = T59920.M_CTR and
T89740.CTR = T59920.BC_CTR
The problem we face is that BC_CTR table has 300,000 rows. We want OBI to first query on BC_M_FCT and M_CTR tables and then query on BC_CTR table. So query should do something like the below:
Select a, b, c....
from
BC_CTR T89740 inner join
(M_CTR T49296 inner join BC_M_FCT T59920 on T49296.CTR = T59920.M_CTR) on T89740.CTR = T59920.BC_CTR
I tried setting Driving table in BMM to the fact table but this is not changing the query. How can I force the query to be changed ?
Thanks,
Sheela

In the property of a dimension level, you have a field "number of elements at this level" (a count).
Check here :
http://download.oracle.com/docs/cd/E12103_01/books/admintool/admintool_BusModSetup20.html
and serach "number of elements"
It's an equivalent to the number of rows. Therefore if you fill in in the lowest level, it's the number of rows in your table.
The documentation said that :
"This number is used by the Analytics Server when picking aggregate sources. The number does not have to be exact, but ratios of numbers from one logical level to another should be accurate"
But if you think that a table is an aggregate source at the lowest level, it can MAY BE influence the query.
I never try.
But I repeat the best way to improve your query is to gather your database statistics :
http://gerardnico.com/wiki/database/oracle/oracle_db_statistics
because the database will rewrite your sql in any way and you will see no improvement.

How to use Inner join of table as Source in Merge statement in SQL

Hi All,
I am trying to make source as multiple tables output using Join while coding there is no any syntax error but when i am executing this statement is giving following error
Following is the query

How to 'inner join' internal table or cluster table ??

Hi,
when i inner join table BSEG it said is a cluster table can't be inner joined .
i wonder how i can "inner join" bseg with a internal table such as
data: begin of i_bseg_trans,
        bukrs like bseg-bukrs,
        gjahr like bseg-gjahr,
        belnr like bseg-belnr,
        total_runtimes like i_runtimes-total,
        already_runtimes like i_runtimes-already,
        left_runtimes like i_runtimes-left,
      end of i_bseg_trans.
and similar things trouble me when considering several internal tables .
thanks for any help!!

Hi,
but if there's more than 2 tables, for example
data: begin of it_bseg occurs 0,
        bukrs like bseg-bukrs,
        else_1 type i,
     end of it_bseg.
data: begin of t occurs 0,
        bukrs like bseg-bukrs,
      end of t.
data: begin of r occurs 0,
        bukrs like bseg-bukrs,
        else type c,
      end of r.
select bukrs from bkdf into table t.
select bukrs from bkdf into corresponding fields of table it_bseg.
select bseg~bukrs      "else_1
from bseg      "it_bseg
into table r
for all entries in t
where bseg~bukrs = t-bukrs.
      " and it_bseg-bukrs = t-bukrs.
in the select clause i mean whether there's a method similar to the way just drop the " in my code.
now my solution is to use another loop on it_bseg, but i think when table amount is large this is really a boring solution.

INNER JOIN 4 tables only 2 share 1 column?

Hey guys,
It's been a while since I have used SQL but I am getting back into it. Currently I am trying to link 4 tables, but two of the tables share one piece of information, in this case it is the (Royalty) column. I have a lot of columns listed in my SELECT, but
for this example I will just show you the basic problem. I am receiving this error when I Execute the script:
"Msg 209, Level 16, State 1, Line 24 Ambiguous column name 'royalty'."
When I remove the (Royalty) from my SELECT group and just leave my other columns in there, the problem goes away.
SELECT
royalty
FROM
stores
INNER JOIN sales
ON stores.stor_id=sales.stor_id
INNER JOIN titles
ON sales.title_id=titles.title_id
INNER JOIN roysched
ON titles.title_id=roysched.title_id
stor_id and title_id are two keys that I found that have a relationship between these 4 tables. Are you able to link keys or can you only link columns together?

You need to alias the royalty column.Not sure of your table structure. Its because Royalty is available in more than 1 table, hence the the ambiguity.
SELECT
stores.royalty --if royalty is not part of stores, give the correct table name
FROM
stores
INNER JOIN sales
ON stores.stor_id=sales.stor_id
INNER JOIN titles
ON sales.title_id=titles.title_id
INNER JOIN roysched
ON titles.title_id=roysched.title_id

Inner join 4 tables

can anyone give example how to join 4 tables?
SELECT mara~matnr werks xchar mtart matkl meins trame umlmc
         INTO CORRESPONDING FIELDS OF TABLE t_mat
         FROM mara INNER JOIN marc
         ON maramatnr = marcmatnr
         WHERE mara~matnr IN matnr
           AND werks IN werks
           AND mtart IN matart
           AND matkl IN matkla
           AND ekgrp IN ekgrup
           AND mara~lvorm = lvorm.
select mblnr mjahr matnr werks
       from mseg
       into table it_mseg
       for all entries in t_mat
       where matnr = t_mat-matnr
   and werks = t_mat-werks.
select mblnr mjahr budat
       from mkpf
       into table it_mkpf
       for all entries in it_mseg
       where mblnr = it_mseg-mblnr
       and mjahr = it_mseg-mjahr.
i m adding additional field in the selection screen "BUDAT FROM MKPF'..
so look at the above code, how i wrote to get the details of bkpf.
so now i just want one select statement where it picks mara, marc fields along with mkpf-budat.

Consider these 4 tables. MARA , MARC , MARD , MAKT.
then select query will be to join all these 4 tables.
Select AMATNR AMTART BWERKS CEINME CSPEME DMAKTX
          FROM MARA AS A INNER JOIN MARC AS B ON
           AMATNR = BMATNR INNER JOIN MARD AS C ON
           BMATNR = CMATNR INNER JOIN MAKT AS D ON
           CMATNR = DMATNR INTO CORRESPONDING FIELDS OF TABLE
ITAB WHERE A~MATNR IN SO_MATNR.
Note : SO_MATNR is the variable of selection screen.
Using these select query you can get the field from all 4 tables.

Dipendra Panwar.

Hi Dipendra,
if you call a report twice after another with the same test data for data selection, then the second run should be faster, because some data are remaining in memory and needn't to be caught from database. This will be also for the following third und further runs, until the data in the SAP memory will be removed by other programs.
For performance traces you should try to test with a first run.

Need help with inner join and distinct rows

Hey Guys,
i have
1) BaseEnv Table
2) Link Table
3) BaseData Table
Link table has three columns Id,BaseEnvId,BaseDataId
the BaseEnvID is unique in the table where as BaseDataId can be repeated i.e multile rows of BaseEnv Table can point to same BaseData table row
Now i want to do BaseEnvTable inner join Link Table inner join BaseData Table and select 5 columsn ; Name,SyncName,Version,PPO,DOM from the BaseData table.. the problem is that after i do the inner join I get duplciate records..
i want to eliminate the duplicate records , can any one help me here

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums. Now we have to guess and type, guess and type, etc. because of your bad manners.
CREATE TABLE Base_Env
(base_env_id CHAR(10) NOT NULL PRIMARY KEY,
Think about the name Base_Data; do you have lots of tables without data? Silly, unh?
CREATE TABLE Base_Data
(base_data_id CHAR(10) NOT NULL PRIMARY KEY,
Your Links table is wrong in concept and implementation. The term “link” refers to a pointer chain structure used in network databases and makes no sense in RDBMS. There is no generic, magic, universal “id” in RDBMS! People that do this are called “id-iots”
in SQL slang.
We can model a particular relationship in a table by referencing the keys in other tables. But we need to know if the relationship is 1:1, 1:m, or n:m. This is the membership of the relationship. Your narrative implies this:
CREATE TABLE Links
(base_env_id CHAR(10) NOT NULL UNIQUE
REFERENCES Base_Env (base_env_id),
base_data_id CHAR(10) NOT NULL
REFERENCES Base_Data (base_data_id));
>> The base_env_id is unique in the table where as base_data_id can be repeated I.e multiple rows of Base_Env Table can point [sic] to same Base_Data table row. <<
Again, RDBMS has no pointers! We have referenced an referencing tables. This is a fundamental concept.
That narrative you posted has no ON clauses! And the narrative is also wrong. There is no generic “name”, etc. What tables were used in your non-query? Replace the ?? in this skeleton:
SELECT ??.something_name, ??.sync_name, ??.something_version,
??.ppo, ??.dom
FROM Base_Env AS E, Links AS L, Base_Data AS D
WHERE ?????????;
>> I want to eliminate the duplicate records [sic], can any one help me here?<<
Where is the sample data? Where is the results? Please read a book on RDBMS so you can post correct SQL and try again.

Inner join between OBOE and OBOT

Hi all,
I am trying to query these tables, but for all the system displays data from these tables in only one windows, MSQL does not inner join this tables.
So, we are looking for the relation in these two tables, or between OBOE and JDT1/OJDT would be enought.
Thanks and regards,
Javier Zapata

Hi,
i'm not sure but you can try to use the table BOT1 (Bill of Exchange Transactions details).
Here you can find the field AbsEntry (related to the table OBOT) and the field BOENumber (related to OBOE table).
Hope this helps

Inner Join performance problem.

Hi,
I wrote a select statement using inner join on table VBRK , VBUK, VBAP and VBRP.
This select statement is working fine from last two years, but suddenly to execute this select statement
taking lot of time and program going to dump.
But same select statement is working in development and quality systems and not working in production system. Based on given selection we check the tables in production we found only 10 records, but to fetch these 10 records also it will taking lot of time and going to dump.
can anyone please advise on the same.
Thanks in advance.

Hi,
Please:
1. Create DB view instead of inner join
2. Use the primary key of the base table (the first or main table in your view) in your where clause
3. If not possible, then you need to create secondary index in your base table that match with your where clause fields.
4. Try to use positive relationship operator, like EQ instead NE, GT, etc.
Hope it helps.

Inner join in crystal 2008

Hi All,
I am new to Crystal report 2008, i have a requirement in which i have to make new connection to Access database which has two tables in it. I have to inner join two tables in crystal reports where the condition is that 1st table contains date and time field and other table has only month. I have to inner join these two fields with key month.Can it be done in crystal reports or i have work on Access itself?
Regards,
Vikram Sukumar

Hi Vikram,
You should be able to do it in CR as long as the data types are compatibles:
-Create blank report;
-From Database Expert, create connection to Access then select the tables to use in the report (if at least 2 tables are selected, the 'Links' tab will appear);
-Go to 'Links' tab;
-Drag a field from one table to a field in another table.
If successful, a link line is created. If unsuccessful, a message is issued.
Note: You can link tables by table name or by foreign key information.
Note: When manually creating links, the field you are linking "to" must be of the same data type as the field you are linking from
