CMIS JOIN Queries and UCM

HI Guys,
Quick question. Does the UCM CMIS integration support JOINs in the query syntax ?
I am trying to construct a query whereby I need to see the Content Items where the Document Title is repeated in multiple folders. The use case is that we want enforce unique names for each content item and we want to highlight those documents that have the same name.
Seems like constructing a CMIS query with JOINS across folders by Content Name seems like a good fit but just wanted to check that will UCM support such a construct before I start developing.
Cheers
Sanjay

I just read this in the CMIS documentation:
"CMIS queries return a Result Set where each Entry object will contain only the properties that were specified in the query. As the Content Management REST Service does not support JOINs in queries, each result entry will represent properties from a single node. Common searches use a query like "SELECT * FROM …"."
"When searching documents (select * from cmis:document), it is not possible to limit the search to more than just a single content type; for example, this is not supported: "select * from IDC:MyProfile, IDC:AnotherProfile" because it has multiple explicit content types and JOINS are not supported."
So i'm afraid it will not be possible...

Problem with Join Queries using PHP and an Orcale Database

Ok, I am trying to build a simple php querying tool for my oracle database and for the most part it is working however I am having a problem getting data from my join queries. If I run the following query :
QUERY:
SELECT lastfirst,EnteredBy,Debit FROM students sts JOIN GLDetail gl ON gl.studentid=sts.id
RESULT SET:
Lastfirst     EnteredBy     Debit
caiu, test      204     1
But when I run the query correctly I get no results
QUERY:
SELECT sts.lastfirst,gl.EnteredBy,gl.Debit FROM students sts JOIN GLDetail gl ON gl.studentid=sts.id
RESULT SET:
sts.lastfirst     gl.EnteredBy     gl.Debit
and if I run the query combining the two above methods and adding a field (schoolid) that has the same name on both table I get the following result sets
QUERY:
SELECT lastfirst,EnteredBy,Debit,sts.schoolid FROM students sts JOIN GLDetail gl ON gl.studentid=sts.id
RESULT SET:
lastfirst     EnteredBy     Debit     sts.schoolid
caiu, test      204     1
QUERY:
SELECT lastfirst,EnteredBy,Debit,schoolid FROM students sts JOIN GLDetail gl ON gl.studentid=sts.id
RESULT SET:
NONE
Therefore, I have to have something written incorrectly in my php code and I just can not figure it out. My entire code is pasted below please provide me with an assistance you might have to offer. I have change the odbc_connec line so I could post it to this forum. In addition, I had to phrase out the column headers there for when you write the column headers you have to use ~ instead of , as the separator and then I turn back into the correct format for sql.

This looks more like a SQL question than a PHP issue. There are a couple of JOIN examples at http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_10002.htm#i2066611 that might you work through the problem.

Can join queries in Oracle 8i and above span multiple databases

Hi,
In Oracle 8i and above, can join queries span multiple databases??
For eg., I have two databases A and B, and say database A has table A_T and
database B has table B_T. Assume that both the databases are on the same
server.
Can I run a join query from my application using OCI calls that spans across
tables from multiple databases, namely, A_T and B_T?
My query probably looks like this - Select * from A.A_T, B.B_T;
Thank you,
Sashi

My query probably looks like this - Select * from A.A_T, B.B_T;If you create a database link from database A to B your SQL would look something like this:
select * from A.A_T, B.B_T@dbB where A.A_T.PK = B.B_T.PK@dbB
The Oracle manuals should have the information you need on creating a database link.

SELECT, hierarchical queries and JOIN

Hi everyone,
I have a small SELECT statement but I can't find an easy solution.
Look at this situation:
drop table departments;
CREATE TABLE departments
dpt_id NUMBER(10) UNIQUE,
dpt_name VARCHAR2(100),
dpt_parent_id NUMBER(10)
TRUNCATE table departments;
INSERT INTO departments VALUES(1, 'Company', null);
INSERT INTO departments VALUES(2, 'HR', 1);
INSERT INTO departments VALUES(3, 'SALES', 1);
INSERT INTO departments VALUES(4, 'IT', 1);
INSERT INTO departments VALUES(222, 'Helpdesk', 4);
INSERT INTO departments VALUES(223, 'French Speaking', 222);
INSERT INTO departments VALUES(224, 'Another level', 223);
INSERT INTO departments VALUES(5, 'LEGAL', 1);
INSERT INTO departments VALUES(66, 'Recruitment', 2);
INSERT INTO departments VALUES(33, 'Logistics', 2);
INSERT INTO departments VALUES(39, 'Fleet management', 33);
INSERT INTO departments VALUES(31, 'Local Sales', 3);
INSERT INTO departments VALUES(60, 'European Sales', 3);
INSERT INTO departments VALUES(61, 'Germany', 60);
INSERT INTO departments VALUES(62, 'France', 60);
INSERT INTO departments VALUES(620, 'Paris', 62);
INSERT INTO departments VALUES(621, 'Marseilles', 62);
INSERT INTO departments VALUES(38, 'American Sales', 3);
INSERT INTO departments VALUES(34, 'Asian Sales', 3);
CREATE table persons
person_id NUMBER(10) UNIQUE,
person_name VARCHAR2(100),
person_dpt_id NUMBER(10)
truncate table persons;
INSERT INTO persons VALUES(1, 'Jim', 2);
INSERT INTO persons VALUES(2, 'Jack', 621);
INSERT INTO persons VALUES(3, 'John', 620);
INSERT INTO persons VALUES(4, 'John', 224);
INSERT INTO persons VALUES(5, 'Fred', 61);It's a simple hierachy like the one we can find in HR schema. The link between an department and its parent is with parent id. THe following statement build the whole tree:
SELECT dpt_id, level, LPAD(' ', LEVEL-1)|| dpt_name
FROM departments
START WITH dpt_parent_id IS NULL
CONNECT BY dpt_parent_id = PRIOR dpt_id;As you can see in the script above, I have a few people assigned to these departments. It's also a classic situtation...
I would like to have something like this:
WITH temp AS
SELECT dpt_id, dpt_name, SYS_CONNECT_BY_PATH(dpt_name, '#') as full_path
    FROM departments
   START WITH dpt_parent_id IS NULL
CONNECT BY dpt_parent_id = PRIOR dpt_id
SELECT p.person_name, d.dpt_name, --d.full_path,
       regexp_substr(d.full_path, '[^#]+', 1, 2, 'i') as t1,
       regexp_substr(d.full_path, '[^#]+', 1, 3, 'i') as t2,
       regexp_substr(d.full_path, '[^#]+', 1, 4, 'i') as t3,
       regexp_substr(d.full_path, '[^#]+', 1, 5, 'i') as t4
FROM persons p
JOIN temp d ON d.dpt_id = p.person_dpt_id;This is the exact output I want, but I wonder... Is it possible to do it without the factored sub-query? It's nice and works fine but I had to precompute the whole path to split it again. I mean, this should be possible in one step. Any suggestion?
I'm using Oracle 10g
Thanks,

I have a person, and I want to see his department and the path in the tree.Actually, you want more than that; you want to parse the path, and display each #-delimited part in a separate column. If you didn't want that, then you could do away with the 4 REGEXP_SUBSTR calls, like this:
WITH temp AS
SELECT dpt_id, dpt_name
,       SUBSTR ( REPLACE ( SYS_CONNECT_BY_PATH ( RPAD (dpt_name, 15)     -- Using 15 just for demo

           )     as full_path
    FROM departments
   START WITH dpt_parent_id IS NULL
CONNECT BY dpt_parent_id = PRIOR dpt_id
SELECT p.person_name, d.dpt_name, d.full_path
FROM persons p
JOIN temp d ON d.dpt_id = p.person_dpt_id;Output:
PERSON_N DPT_NAME      FULL_PATH
Jim      HR            HR
Fred     Germany       SALES          European Sales Germany
John     Paris         SALES          European Sales France         Paris
Jack     Marseilles    SALES          European Sales France         Marseilles
John     Another level IT             Helpdesk       French SpeakingAnother levelAs you can see, full_path is one giant column, but it's formatted to look like 4 separate columns, forresponding to your original t1, t2, t3 and t4. I limited the output to 15 characters, just for debugging and posting purposes. You can use any number of characters you like.
It's too complex for this simple thing.It would be nice if there was something simpler that did exactly what you wanted, but I'm not sure it's reasonable to expect it in every case. I asked a lot of questions in my first message, but I'm not sure you've tried to answer any of them, so I'm not sure why you're unhappy with the query you posted. I can think of lots of ways to change the query, but I have no way of telling if you would like them any better than what you already have.
And hopefully, I know where to start in the hierarchy and I know where to stop. If I had to show all the levels and have one column by level dynamically, I'd be stuck. Sorry, I don't understand this part.
Are you saying that it seems inefficient to generate the entire tree, when perhaps few of the nodes will have have matches in the persons table? If so, you can invert the whole query. Instead of doing the CONNECT BY first and then joining, do the join first and then the CONNECT BY. Instead of doing a top-down CONNECT BY, where you start with the parentless nodes (whether or not you'll ultimately need them) and then find their descendants, do a bottom-up CONNECT BY, where you start with the nodes you know you'll need, and then find their ancestors.
I just find it difficult for such a simple need. Again, there are lots of things that could be done. If you won't say what you want, that makes it hard for me to tell you how to get it. All that I've picked up for sure is that you don't like doing a sub-query. That's unfortunate, because sub-queries are so basic. They have very important been since Oracle 8.1, and they don't seem to be going away. Quite the opposite, in fact. You need sub-queries for all kinds of things, not just CONNECT BY. To give just a couple of examples, they're the only thing that make analytic functions really useful, and they simplfy chasm traps (basically, multiple 1-to-many relationships on the same table) considerably. I'm sorry if you don't lke sub-queries, but I don't see how you can work in this field and not use them.

Hi,
Welcome to the forum!
Whenever you post code, format it to show the extent of sub-queries, and the clauses in each one.
Type these 6 characters:
\(all small letters, inside curly brackets) before and after each section of formatted test; if you don't, this site will compress the spaces.
It also helps it you reduce your query as much as possible. For example, I think you're only asking about the sub-query called caloc, so just post caloc as if that were the entire query:select     ( select CIRCUIT_ID
     from cid
     )                as CIRCUIT_ID,
     ( select sl.name
     from nc_objects          sl
     join nc_references      scr on sl.object_id = scr.reference
     where scr.attr_id      = 3090562190013347600
     and scr.object_id      = sc.object_id
     )                as ALOCATION
from sc
This makes it much cleared that the query will produce 2 columns, called circuit_id and alocation.
Compare the query above with the query below:SELECT     object_id,
     'Okay'
FROM     sc
The basic structure is the same: both queries produce two columns, and both queries produce one row of output for every row that is in the sc table.
The only difference is the two items in the SELECT clause.
The second query has a column from the table as its first column, and a literal for its second column; those are just two of the kinds of things you can have in a SELECT clause. another thing you can have there is a +Scalar Sub-Query+ , a complete query enclosed in parentheses that produces exactly one column and at most one row.   If a scalar sub-query produces more than one row, then you get the run-time error: "ORA-01427: single-row subquery returns more than one row", as you did.
A scalar sub-query always takes the place of a single value: "scalar" means "having only one value". In the first example above, the main query is supposed to produce one row of output for every row in sc. How can it do that if some of the columns themselves contain multiple rows?
I don't know what your tables are like, or what output yu want to get from thiose tables.
If you'd like help getting certain results from your tables, then post CREATE TABLE and INSERT statements for a little sample data, and the resutls you want to get from that sample data. A scalar sub-query may help getting those results, or it may not.

Prob in joining Query1 and Query2 in Data Model

Hi,
I m facing a prob. in joining Multiple queries
Under data model I've created 2-3 queries which I've to join internally and in my Query1 only 1 bind variable is there, for which i've created a parameter
but for Query2 and Query3 I m going to user one column value of Query1 as parameter.
When i m doing this the Xml formed returns only Query1 value and Query2 and Query3 comes as blank.
Eg.
Query1 : select deptno,dname from dept where deptno=:p_deptno <:p_deptno is a parameter created in parameter list>
Query2 : select empno,ename,mgr from emp where deptno=:deptno <where :deptno, i m expecting to come from Query1>
but it not happening
whereas my Xml comes as display below:
<DATA>
<Q2>
<Q2_ROW>
<DEPTNO>10</DEPTNO>
<DNAME>ACCOUNTING</DNAME>
</Q2_ROW>
</Q2>
<Q1 />
</DATA>
tanks in advance for replying

Personally, I have had a hard time doing what you are asking for using netui tags. I have had the same case, and asked the person in my team to just return a collection of value objects and then iterate through it without the repeater tag. To use the checkbox, I have had to use a String[].

ANSI SQL Syntax - What belongs to join-clause and what to where-clause

Hello,
we currently have a discussion about the ANSI SQL Syntax where we do not agree what belongs to the join clause and what belongs to the where clause in an ANSI Sytnax SQL Query.
Lets say there is a query like this:
+SELECT *+
FROM employees emp, departments dept
WHERE emp.dept_country = dept.dept_country
AND emp.dept_name = dept.dept_name
AND dept.dept_type = 'HQ'
AND emp.emp_lastname = 'Smith'
Primary key of the departments table is on the columns dept_country, dept_name and dept_type. We have a Oracle database 10g.
Now I have rewritten the query to Ansi Syntax:
+SELECT *+
FROM employees emp
JOIN departments dept
ON emp.dept_country = dept.dept_country AND emp.dept_name = dept.dept_name
WHERE dept.dept_type = 'HQ'
AND emp.emp_lastname = 'Smith'
Another developer says that this is not completely correct, every filter on a column that belongs to the primary-key of the joined table has to be in the join clause, like this:
+SELECT *+
FROM employees emp
JOIN departments dept
+ON emp.dept_country = dept.dept_country AND emp.dept_name = dept.dept_name AND dept.dept_type = 'HQ'
WHERE emp.emp_lastname = 'Smith'
Can somebody tell me which on is correct?
Is there any definition for that? I couldn't find it in the Oracle Database definition.
I just found out the names of the ANSI documents here: http://docs.oracle.com/cd/B19306_01/server.102/b14200/ap_standard_sql001.htm#i11939
I had a look at the ANSI webstore but there you have to buy the PDF files. In my case thats exaggerated because both of the Queries work and i am just interessted if there is one correct way.
Thank you in advance
Marco

Hi,
As i guideline i would say, answer the question: should the result of the join be filtered or should only filtered rows be joined from a particular table?
This is helpful in the case of outer joins also, for inner joins it doesnt matters as said already be former posters, where there may be hughe semantical differences depending of where the predicates are placed.
From performance view, if we talk about oracle, take a look a the execution plans. You will see that there is (probably) no difference in case of inner joins. Even in case of outer joins the optimizer pushes the predicate as a filter towards the table if it semantically possible.

Bind variables in inner join queries

can we use bind variables in inner join queries?

Dear,
can we use bind variables in inner join queries?Where are you using this join? if in a stored procedure or stored function than you don't have to care about your variables. It will be automatically considered as a bind variable
within your static SQL (i.e in your stored procedure)
Hope this helps

In which sequence are queries and sub-queries executed by the SQL Engine

In which sequence are queries and sub-queries executed by the SQL Engine?
Which is correct ?
a. primary query -> sub query -> sub sub query and so on
b. sub sub query -> sub query -> prime query
c. the whole query is interpreted at one time
d. there is no fixed sequence of interpretation, the query parser takes a decision on the fly

Hi, below may help you understanding simple subquery & correlated subquery
refer :
http://sqlmag.com/t-sql/t-sql-starters-simple-and-correlated-subqueries
a) if it is correlated subquery
A correlated subquery is one that depends on a value in the outer query. In programming terms, you pass the subroutine an argument, then the subroutine evaluates the query and returns a result. You move on to the next record and repeat the process. The
net effect is that the subquery runs once for every row in the main query; this situation is inefficient.
A possible alternative is to rewrite the correlated subquery as a join. However,
some situations require a subquery. Eg- IN(with outer table refernce)
so main query -> subquery
b) if it is simple subquery
A subquery is a query that SQL Server must evaluate before it can process the main query, Eg- IN(with out outer table refernce)
so subquery-> main query
c) correlated query interpreted row by row with subquery, while subquery is interpreted at one time(outer table and inner table)
d) in most case it depends on the whether it is correlated subquery or simple subquery

System table of Queries and charactistics.

Hello
Is there any RS* table or an RSZ* table or a join of these that contains all the queries and the characteristics in them?
If there is one, does it also indicate, even if the characteristic is used 'indirectly' such as ... for example restricted key figures?
Thanks for any help....Raju.

Hi Martin,
I would suggest to post this question in the abap forum.

Webserver and UCM in different machines

As the title said.. how do I do this? in the installation guide it's just for both in one machine but how do i install webserver in a windows server and UCM in a unix server?
Is this even possible? please some advice or redirect to some solution,
Thanks

Hi
Look at Note : 885983.1 on metalink . This gives the steps to configure Cs when webserver is on a different machine altogether.

Weblogic portal 10.3.1 framework and UCM 10gR3 code works in Jdeveloper

Hi All,
We are using weblogic portal 10.3.1 framework and UCM 10gR3. Now we want to use Jdeveloper (because we can integrate site studio using plugin) instead of weblogic workshop.
So my question is does the existing code works in Jdeveloper (because it supports Webcenter portal)?.
Thanks,
Venkata Sarvabatla

No. Eclipse/Worskhop is the development IDE for WLP. While you can probably edit many of the WLP artifacts in JDeveloper, since they're mostly XML files, JDeveloper won't understand the WLP project structure, understand many of the libraries or know how to deploy to a WLP domain.

BPM and UCM Integration

I want to save some flexField value of a BPM human task into a custom field created in UCM doc store, for that i am following the following steps
1) Created a custom field in UCM document store
2) Created a flex field in BPM work Space
3) Added pay load in human task from the "*data*" tab of human task flow
4) Mapped Pay load with the flex field of BPM Work Space
5) Now when I want to map the pay load attribute by adding a custom attribute in the "documents" tab of the human task, IDE is not allowing to add any custom fields except the pre populated values.
In this situation if I want one of my human task payload attribute to be saved in the custom field created in the document store how to do it. According to the Oracles guide we can add a new attribute through the "**document**" tab of the human task flow but it is not happening.

OK, so you are using the attachment option from BPM.
I gave you few hints in my previous post, but I will explain them in more details:
a) BPM has its own metadata
Forget for your document for a moment - the BPM process instance still can have its own metadata. These are used when you create BPM screen flows.
I think you will need to create a BPM parameter to store your custom value first. (and this is really purely a BPM question)
b) A document can be attached to a BPM process instance
In a sense, such a document is nothing, but an additional information for the BPM process instance. This has nothing to do with document-oriented workflow (quite often, the attached document enters no workflow at all); it is the BPM process instance that routes across the organization, not the document.
c) BPM metadata <--> UCM metadata
AFAIK, there is no integration between BPM and UCM concerning metadata. You may check-in (attach) a new document using UCM profiles, but for your process this value is not visible - unless you call a service to retrieve it/update it. If you implemented a) (created your custom value in BPM), you may call UCM's services to update this value - at the minimum when you are leaving from the BPM workflow step.

Just joined bt and have a real big problem!!!!

hello there i was very happy untill this morning with my new bt infinity package which was installed last tuesday.i have only just realised with horror that i have taken delivery of the wrong tv box.we have chosen a humax youview box when we should have opted for a bt vision+ box so we could receive the extra 18 channels and sport.we ordered over the phone and i was told it was just a matter of paying a £10 fee to get espn and i didnt realise the extra channels i was paying an additional £12.50 for was the six packs add on which is completely different.anyway i rang up this morning and was told it would cost £199 to change boxes!!!!!!.is this correct??.if so ive got a year with a useless box with next to nothing i want to watch!!.what are my options please.

stuart can you give me a bit more info about the schedule for the humax box being enabled?
It is scheduled for the summer but lime all schedules it could slip. It requires an update to the software
They are currently working on delivering this service to those who have the existing boxes ie the Black Vision Box. The two separate platforms will disappear in time with YouView being the future. Have you checked to see if your exchange is multicast enabled
