Join with another table in pre-query

Hi,
We have a large data block and we need to order some columns based on street name for example, not id. The base table of db block contains an id_street column, and 'streets' table contains id and name.
Ok, in pre-query trigger of that block, we have a complex logic and we dynamically build the where clause. At the end, we set the order_By clause of the block, to order the rows, for example we need to order by the 'my_date' column asc (it's a date type column), and street desc; but street NAME, not id. We don't want to use a from clause query, because the dynamically where clause logic it's complex.
How can we join the db block table with 'streets' table in pre-query, so when constructing the order by clause to specify something like
set_block_property('ADRESE_NEZONATE', order_by, 'my_date, name desc');where 'name' is the name of the street, from the 'streets' table.
Is it possible in pre-query, somehow? Or, in my case where can I join with that table and use that column in pre-query at setting order by?
Thanks!

I understand what you say but partially.. please explain in more detail how to do that;
How should look the adrese_nezonate block, then? I have to add a 'name' column and set copy value from item property to 'STREETS.NAME', and database_property No?
Then the post-query trigger how should look like (the order by clause)? The post-query sends the entire query (with where/order by clauses) to the server, but in that "select... where... order by" (built dynamically) there are only columns from that block (adrese_nezonate). I need to join with streets, INSIDE that query.
Thanks.

There is no limit to the number of tables you can outer join as long as you join them correctly.

Update Problem - Join With Another Table

I'm trying to convert few MS Access Queries into Oracle. Following is one of the query from MS Access.
<font face="courier">
UPDATE [RESULT] INNER JOIN [MASTER]
    ON ([RESULT].[LAST_NAME] = [MASTER].[LAST_NAME])
   AND ([RESULT].[FIRST_NAME] = [MASTER].[FIRST_NAME])
   AND ([RESULT].[DOCUMENT_NUMBER] = [MASTER].[DOCUMENT_NUMBER])
   AND ([RESULT].[BATCH_ID] = [MASTER].[LEAD_ID])
SET [MASTER].[CLOSURE_REASON] = "Closed For Name and Document Number Match",
    [MASTER].[RESULT_ID] = [RESULT].[ID],
    [MASTER].[RESULT_PID] = [RESULT].[PID]
WHERE (([MASTER].[CLOSURE_REASON] Is Null)
   AND ([MASTER].[REC_CODE] = "A1")
   AND ([RESULT].[EVENT_DATE] = [MASTER].[EVENT_DATE])
   AND ([RESULT].[EVENT_TYPE] = "Open")
   AND ([MASTER].[DOCUMENT_NUMBER] Is Not Null)
   AND ([MASTER].[DOCUMENT_NUMBER)] "null"));
</font>
First I received ORA-01779: cannot modify a column which maps to a non key-preserved table Error. I followed different examples (including MERGE) from your
site and modified my original query. Now, I receive ORA-30926: unable to get a stable set of rows in the source tables Error.
Most of the examples showed only one join between the tables but I have to make more joins based on my requirements.
Any help translating this query in to Oracle would be Great. Thanks!

Assuming that the columns you are joining to in the result table are the whole PK or are declared as aunique contraint (i.e. some combination of last_name, first_name, document_number, batch_id, event_date, id, and pid make up the entire PK/unique constraint), then the updateable join view should look something like:
update (select m.last_name, m.first_name, m.document_number, m.lead_id,
               m.closure_reason, m.result_id, r.id, m.result_pid, r.pid
        from master m
           join result r
              on r.last_name = m.last_name and
                 r.first_name = m.first_name and
                 r.document_number = m.document_number and
                 r.batch_id = m.lead_id and
                 r.event_date = m.event_date
        where m.closure_reason is null and
              m.rec_code = 'A1' and
              r.event_type = 'Open' and
              m.document_number is not null and
              m.document_number != 'null')
set closure_reason = 'Closed For Name and Document Number Match',
    result_id = id,
    result_pid = pidThe merge version would look something like:
merge into master
   using (select last_name, first_name, document_number, batch_id,
                 event_date, id, pid
          from result
          where event_type = 'Open') r
   on (r.last_name = m.last_name and
       r.first_name = m.first_name and
       r.document_number = m.document_number and
       r.batch_id = m.lead_id and
       r.event_date = m.event_date)
   when mathed then
      update
      set closure_reason = 'Closed For Name and Document Number Match',
          result_id = id,
          result_pid = pid
      where m.closure_reason is null and
            m.rec_code = 'A1' and
            m.document_number is not null and
            m.document_number != 'null';However, as Hoek pointed out, the combination of last_name, first_name, document_number, batch_id, event_date, id, and pid must point to a unique row in the result table, whether they make up the PK or a unique constraint. If there are, or could be, multiple rows for a particular combination of last_name, first_name, document_number, batch_id, event_date, id, and pid, then you will need to find a way to determine which of those rows should be used to do the update.

Case statement resulting into Left outer join with other tables

Hi All ,
I am facing a stuation where a Case statement on one of the logical columns in Answers is resulting into a left outer join with a table in the query.
If we remove the case stmt, the table is not being acessed.
The case stmt is a simple one and no other logical column is being accessed in the case stmt.
Please advice .
Thanks.

Hi Sai,
No ..we dont have any left outer join ...its just that I am selecting measure from F1 which has a confimred dimension D1 with F2.Now when I dont have case stmt on measure from F1(Case stmt is something like : CASE WHEN "- P table"."P Column" = 'Y' THEN 'Right' ELSE 'Wrong' END), then it doesnt query F2.
However as soon as I introduce the case stmt ,the query creates a left outer join with F2.
Thanks.

Can we join two totals tables in ABAP Query

Hey Gurus!
Can we join two totals tables in ABAP query.
I am tyring to join FAGFLEXT with internal orders totals table.
Thanks

Hi,
Report painter majorily operates around characteristics and key figures.
ABAP query comes even more handy. The advantage is -
1. You can link many tables
2. Create selection screen as you like to have
3. User friendly report creation
4. Logic can also be coded.
5. Authorization can be set
I have written a article in SDN, which gives you an idea as to how to go about using ABAP query. Have a look on this - [Article - Practical Usage of ABAP Query|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/20f6b256-23be-2b10-8b93-cad83a617634]

Avoid duplicates when i join with bridge table

i have a requirement with many to many relations between fact and dimention,that is the reason we have created bridge tables in the database.
if i execute only query on the fact table it is giving correct results.when ever i join with bridge tables it is returning lot of duplicate records.
Ex:
select amount from fact where column = 'xyz'
100
then it is returing one record.(this value is correct)
when ever i join this fact table with bridge table then it is returning duplicate records.
select a.amount from fact inner join bridge table b on a.fk=b.fk
100
100
100
100
100
how many number of fk's associated that many 100's are generating
in this case it is returning duplicate records.
in the RPD i have joined like one to many between fact to dimention.
if anybody face this type of situation please let me know how to resolve this?(FYI...i would have to do this before BM..because lot of other thing are coming into picture on BMM that's why i should have to achieve this in either physical or in database.
Thanks in advance

Adding a single table without a logical join to another table (OBIEE 10g)

Sometimes I want to just display a single table without a logical join to another table in the repository. However, everytime I move it to the Business Model and Mapping layer and perform a Global Consistency Check, it tells me that it needs a logical join and I am forced to create another table to join to it. Thus creating a dimension-fact relationship. There are times I don't need this relationship and just want to display some data. Is there anyway to get around this?
Thanks in advance!

Yes,You have to create a join.You cannot take single table to BMM layer.You can create an alias of the table.Join this alias and base table through any common column and take both tables to BMM and desired table to presentation layer.
Another way is to create a view in physcial layer.Write a select statement like
Select primary_key from Table
Where primary_key is primary key of base table.Join this view ith base table and repeat the steps defined for Alias.

ANSI Standard Join with Nested Table

Does anyone know how to (or whether you actually can) use ansi standard table joins with nested tables.
Non-ansi standard would look something like this
SELECT e.empno
FROM departments d, TABLE(d.employees) e
WHERE d.deptno = 10;
Where d.employees is a nested table.
But if I try ansi-standard I like such:
SELECT e.empno
FROM departments d
JOIN TABLE(d.employees) e
WHERE d.deptno = 10;
I get
ORA-00905: missing keyword
because I have nothing to join it on.
Your help is very much appreciated

Both replies worked fine.
I think I will go with the NATURAL JOIN as it seems the cleanest option.
Thanks Guru 2748

Copy the structure of a table to another with another table name.

how to copy the structure of a table to another with another table name.
ie. i want a emp table with same values/structure to be copied to another table called my_employee.
how can this be done?

create table my_emp as select * from emp;
If you do not want the data to be copied then do the following:
create table my_emp as select * from emp
where 1=2;

Where clause with XMLExists and join on another table

Hi,
We have table like:
drop table xml_tbl;
create table xml_tbl (
xml_msg_id integer,
xml_msg_text xmltype
insert into xml_tbl values
(1, '<main><id>1</id></main>') ;
insert into xml_tbl values --(xml_msg_id,xml_msg_text)
(1, '<main><id>2</id></main>') ;
Another table like:
create Table Table1
( id1 int);
Insert into Table1 values(2);
Insert into Table1 values(3);
We need to have a view on top of the table xml_tbl where /main/id should have only those values which are in id1 column of table Table1.
Something like
CREATE OR REPLACE VIEW V_xml_tbl
xml_msg_text
AS
SELECT T.xml_msg_text
FROM xml_tbl T
WHERE XMLEXISTS (
'declare namespace Namesp1 ="Abc:Set";
let $Results as xs:boolean := fn:exists($p/main/id in (Select id1 from Table1)) --Now here I know I can't do Select id1 from
Table1*
return if ($Results ) then true() else ()'
PASSING T.xml_msg_text AS "p");
Actually in the real scenario Table1 will have many IDs and xml_tbl has many XML files..
So I am stuck on how to do it. Please help.
Thanks..

but join it with rtts_association table to get the rtts_no i m getting 21 records.....
the problems is ... 7 records are getting multiplied by a factor of 3 resulting in 21 records ....
how can i avoid these extra records that appear in the second query

For every combination of raised & cleared columns in "association_1" table, there are 3 records in the "rtts_association" table with different values for "RTTS" as below:
Association_1:
RAISED               CLEARED
03-FEB-2011 22:03:10 03-FEB-2011 22:06:15
rtts_association

03-FEB-2011 22:03:10 03-FEB-2011 22:06:15    1487697
03-FEB-2011 22:03:10 03-FEB-2011 22:06:15    1487649Hence, evidently you wil get 7 (association_1) * 3 (rtts_association) in your output. If you want only one record in the output, you may need to pick any one of the values of RTTS from the 3 different values based on a pre-defined condition (e.g. record corresponding to lowest or highest value of RTTS)

Right way to preserve all parent table entries in a join with many tables!!

This problem is quite interesting to me. I have asked this question to others but no body is able to provide me with proper answers.
The problem is: How do I join a huge parent table with many child tables (more than 5 child tables) preserving all of the parent table entries. Lets say there is the parent table parentTable and three child tables childTable1, childTable2, childTable3. In order to get the data after joining these tables the query that I have been using was:
select parent.field1, parent.field2, parent.field3, child1.field4, child1.field5, child2.field6, child3.field7 from ParentTable parent, childTable1 child1, childTable1 child2, childTable3 child3 where parent.fielda = child1.fieldb and parent.fieldc = child.fieldd and parent.fielde = child.fieldf.
Although the tables are huge (more than 100,000 entries), this query is very fast, however those parent table entries which do not have child entries are lost. I know that I can left join a parent table with a child table and then with the next child table and then with the next child table and continue. Isn't there a simple solution for this commonly happening problem?
Please provide suggestions please...

Hello Lakshmi,
Although I do not know exactly how to achieve what you want to achieve but I have seen DBAs/ABAPers in my experience can run queries/scripts using the COUNT function to give the actual number of line items per table for all your 100 or odd tables.

Outer join with effective date in peoplesoft query

Hi,
I'm trying to join two tables using outer join. Both tables are effective dated:
Dept_Tbl: dept_id, status, effdt
Tips_Tbl: dept_id, tips_id, effdt
Not all records in Dept_Tbl are in Tips_Tbl. I need to get all active depts and their most recent tips_id if they have one.
select a.dept_id, b.tips_id
from dept_tbl a, tips_tbl b
where a.status = 'Active'
and a.effdt =
(select max(a_ed.effdt) from dept_tbl a_ed
where a.dept_id = a_ed.dept_id
and a_ed.effdt <= SYSDATE)
and b.dept_id(+) = a.dept_id
and b.effdt =
(select max(b_ed.effdt) from tips_tbl b_ed
where b.dept_id = b_ed.dept_id
and b.tips_id = b_ed.tips_id
and b_ed.effdt <= SYSDATE)
The query only returns records that are in both tables.
Is there a way for outer join to work with effective dates?
Thanks in advance,
Reg

Here is an example of one solution. Note the use of NVL on both sides of the equal sign since both sides could be NULL in the case of the outer join
with dept_tbl as (select 1 dept_id, SYSDATE effdt FROM DUAL),
     tips_tbl as (select 1 dept_id, NULL effdt FROM DUAL)
select a.effdt
from dept_tbl a,
       tips_tbl b
where b.dept_id(+) = a.dept_id
   and NVL(b.effdt, SYSDATE) = NVL((select max(b_ed.effdt)
                                      from tips_tbl b_ed
                                     where b.dept_id = b_ed.dept_id
                                       and b_ed.effdt <= SYSDATE), SYSDATE);

Yes,Duplicate the fact table create a primary key on the newly fact table alias dimension table.So you can ur data modelling as usual.
