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.

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.

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.

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

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

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

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.

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!

To find the tables which is having link with particular table.

hi all,
i am working on db 10g.
i have table called JOB_HEADER
My task is to delete the data in the job_header table.
Before doing this task, i want to know which are the tables referencing this particular table.
in other words i have to delelete child records first then i have to delete the above said table.
is there any way to know the child table existance for this particular parent table?
Thanks..

Selecting multiple rows a table according to rows passed with a table valued parameter

Ive got a table, which looks like this:
CREATE TABLE MyTable (
MyChars CHAR(3) NOT NULL,
MyId INT NOT NULL,
CONSTRAINT PK__MyTable_MyChars_MyId PRIMARY KEY (MyChars, MyId),
CONSTRAINT FK__MyOtherTable_Id_MyTable_MyId FOREIGN KEY (MyId) REFERENCES MyOtherTable (Id)
Records look like i.e.:
Chars | Id
'AAA' | 1
'BBB' | 1
'CCC' | 1
'AAA' | 2
'BBB' | 2
'CCC' | 2
'DDD' | 2
'EEE' | 3
'FFF' | 3
'AAA' | 4
'DDD' | 4
'FFF' | 4
Now I have a SP, which takes a table valued parameter like:
CREATE TYPE dbo.MyTVP AS TABLE ( MyChars CHAR(3) )
This SP should return a set of Ids, which match all the rows of the parameter.
I.e.:
if the TVP contains 'AAA', 'BBB' & 'CCC', i get as result 1 & 2
if the TVP contains 'AAA' & 'FFF', i get as result 4
if the TVP contains 'BBB' & 'EEE', i get an empty result
What my SP is currently doing, is to build a query with string concatination, which is then executed with the EXEC statement. If we take my first example, the built query would look like this:
SELECT DISTINCT t0.MyId
FROM MyTable t0
INNER JOIN MyTable t1 ON t0.MyId = t1.MyId
INNER JOIN MyTable t2 ON t1.MyId = t2.MyId
WHERE t0.MyChars = 'AAA' AND t1.MyChars = 'BBB' AND t2.MyChars = 'CCC'
It works, but I'm not very fond of building the query. Maintaining such things is always a pain. And it also might not be the most efficient and elegant way to do this.
Since I can't think of any other way of doing this, I wanted to ask, if someone of you got an idea, if there is a better way to accomplish this.

Let me give you a "cut and paste" I use in the SQL Server groups:
1) The dangerous, slow kludge is to use dynamic SQL and admit that any random future user is a better programmer than you are. It is used by Newbies who do not understand SQL or even what a compiled language is. A string is a string; it is a scalar value like
any other parameter; it is not code. Again, this is not just an SQL problem; this is a basic misunderstanding of programming principles.
2) Passing a list of parameters to a stored procedure can be done by putting them into a string with a separator. I like to use the traditional comma. Let's assume that you have a whole table full of such parameter lists:
CREATE TABLE InputStrings
(keycol CHAR(10) NOT NULL PRIMARY KEY,
input_string VARCHAR(255) NOT NULL);
INSERT INTO InputStrings
VALUES ('first', '12,34,567,896'),
('second', '312,534,997,896'),
etc.
This will be the table that gets the outputs, in the form of the original key column and one parameter per row.
It makes life easier if the lists in the input strings start and end with a comma. You will need a table of sequential numbers -- a standard SQL programming trick, Now, the query,
CREATE VIEW ParmList (keycol, place, parm)
AS
SELECT keycol,
COUNT(S2.seq), -- reverse order
CAST (SUBSTRING (I1.input_string
FROM S1.seq
FOR MIN(S2.seq) - S1.seq -1)
AS INTEGER)
FROM InputStrings AS I1, Series AS S1, Series AS S2
WHERE SUBSTRING (',' + I1.input_string + ',', S1.seq, 1) = ','
AND SUBSTRING (',' + I1.input_string + ',', S2.seq, 1) = ','
AND S1.seq < S2.seq
GROUP BY I1.keycol, I1.input_string, S1.seq;
The S1 and S2 copies of Series are used to locate bracketing pairs of commas, and the entire set of substrings located between them is extracted and cast as integers in one non-procedural step. The trick is to be sure that the right hand comma of the bracketing
pair is the closest one to the first comma. The relative position of each element in the list is given by the value of "place", but it does a count down so you can plan horizontal placement in columns.
This might be faster now:
WITH Commas(keycol, comma_seq, comma_place)
AS
(SELECT I1.keycol, S1.seq,
ROW_NUMBER() OVER (PARTITION BY I1.keycol ORDER BY S1.seq)
FROM InputStrings AS I1, Series AS S1
WHERE SUBSTRING (',' || I1.input_string || ','
FROM S1.seq
FOR 1) = ','
AND S1.seq <= CHARLENGTH (I1.input_string))
SELECT SUBSTRING(',' || I1.input_string || ','
FROM C1.comma_place +1
FOR C2.comma_place - C1.comma_place - 1)
FROM Commas AS C1, Commas AS C2
WHERE C2.comma_seq = C1.comma_seq + 1
AND C1.keycol = C2.keycol;
The idea is to get all the positions of the commas in the CTE and then use (n, n+1) pairs of positions to locate substrings. The hope is that the ROW_NUMBER() is faster than the GROUP BY in the first attempt. Since it is materialized before the body of
the query (in theory), there are opportunities for parallelism indexing and other things to speed up the works.
Hey, I can write kludges with the best of them, but I don't. You need to at the very least write a routine to clean out blanks, handle double commas and non-numerics in the strings, take care of floating point and decimal notation, etc. Basically, you must
write part of a compiler in SQL. Yeeeech! Or decide that you do not want to have data integrity, which is what most Newbies do in practice altho they do not know it.
A procedural loop is even worse. You have no error checking, no ability to pass local variables or expressions, etc.
CREATE PROCEDURE HomemadeParser(@input_string VARCHAR(8000))
AS
BEGIN
DECLARE @comma_position INTEGER;
CREATE TABLE #Slices
(slice_value INTEGER);
SET @input_string = @input_string + ','; --add sentinel comma
SET @comma_position = CHARINDEX(',', @input_string);
WHILE @comma_position > 1
BEGIN
INSERT INTO #Slices (slice_value)
VALUES(CAST(LEFT(@input_string, (@comma_position - 1)) AS INTEGER));
SET @input_string = RIGHT(@input_string, LEN(@input_string)-@comma_position)
SET @comma_position = CHARINDEX(',', @input_string)
END;
END;
Better answer:
http://www.simple-talk.com/sql/learn-sql-server/values()-and-long-parameter-lists/
http://www.simple-talk.com/sql/learn-sql-server/values()-and-long-parameter-lists---part-ii/
Do this with a long parameter list. You can pass up to 2000+ parameters in T-SQL, which is more than you probably will ever need. The compiler will do all that error checking that the query version and the procedural code simply do not have unless you write
a full parser with the standard error codes. You can now pass local variables to your procedure; you can pass other data types and get automatic conversions, etc. In short, this is just good software engineering.
CREATE PROCEDURE LongList
(@p1 INTEGER = NULL,
@p2 INTEGER = NULL,
@p3 INTEGER = NULL,
@p4 INTEGER = NULL,
@p5 INTEGER = NULL)
x IN (SELECT parm
FROM (VALUES (@p1), (@p2), (@p3), (@p4), (@p5)) AS X(parm)
WHERE parm IS NOT NULL;
You get all the advantages of the real compiler and can do all kinds of things with the values.

CRVS2010 Beta - Report with many tables

Hi,
I was developing my application first with a test Database with few tables. Now that I am changing to the actual database (with about 200 tables) I noticed that the ReportDocument takes a really long time to load when I tried to access the DataDefinition for the first time.
Is there one way to avoid this?? The tables are all there because I need to have the option the select the table that I wanna use in the application, but after this I just use the table chosen and the linked tables in the Report.
thanks

OK where to start...
First the act of adding 200 tables, and I assume none of them are linked is the first problem you are going to have. CR is a relational database reporting tool. Not linking tables generates multiple SELECT statements.
If you only need one or two then use RAS to add the tables and then the fields, Bascially you are creating the report designer for your users. All of the user interface needs to be created by you.
There may be one option that could help but what you are doing is likely never going to be fast....
Open regedit32.exe and go to:
HKEY_CURRENT_USER\Software\SAP BusinessObjects\Suite XI 4.0\Crystal Reports Designer Component\DatabaseOptions
In there you'll find a key called - DoAutoSmartLinking
Set the value to No
What that key does is when a report is open CR tries to link all tables and all fields.
Good luck

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].[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.

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.

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

21 rows selected.

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    1490980
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)

Sun java Creator, Table component vanishes when associating with the table

I am trying to develop JSF page with a table component and associating a table (users) to the table component.
I have created datasource and i can see the data in the SQL editor in Sun Java Creator.
But when i try to associate the table component with the table(users).
I table component vanishes.
I dont understand what is the problem.
Can anybody help me.

The default theme is localized. If you look at <Creator-install>/rave2.0/modules/ext/locale
you should see the localized default theme jars. Not sure which locale you are. You can put your localized jar here. Add the localized jar to your web application via library manager for it to be included in the deployed war file
