Connect by query, need root element for each row
Hi,
I am working on a hierarchical query, using connect by prior. Each node in the tree has two properties, an type and a sequence.
The table that contains the hierarchy has 4 fields:
element_type_from
element_sequence_from
element_type_to
element_sequence_to
Each child has one parent, a parent can have multiple childeren. For a leaf, the fields element_type_to and element_sequence_to are null.
To generate a tree you can run:
select element_type_to
, element_sequence_to
from element_hierarchy
start with element_type_from = [root_element_type]
and element_sequence_from = [root_element_sequence]
connect by prior element_type_to = element_type_from
and prior element_sequence_to = element_sequence_fromThat works fine... however... not only do I want the child elements, I would like to return the root element sequence for each child (in our table the root element type is always the same). There are multiple root elements and I want to create a list containing all trees and each node in the tree must have its root as well.
There is the option of using sys_connect_by_path. This returns the root, but also the entire path to the current child. Also it returns a varchar2, that needs to be substr-ed and to_number-ed to get to the sequence... not nice.
warning, extremely ugly (but functional) code:
select element_type_to
, element_sequence_to
, to_number(substr(sys_connect_by_path(element_sequence_from ,','),2,instr(sys_connect_by_path(element_sequence_from ,',') ||',',',',2)-2)) root_sequence
from element_hierarchy
start with element_type_from = [root_element_type]
and element_sequence_from = ( select [root_element_sequence] from all_root_elements )
connect by prior element_type_to = element_type_from
and prior element_sequence_to = element_sequence_fromThere has to be a simple solution that I am missing here! Can you help?
Edit: Oops, database version is 10.2.0.4.0
Hi,
What you posted was actually the best way to do it in Oracle 9.
Since you're using Oracle 10, you can use CONNECT_BY_ROOT, as William said:
select element_type_to
, element_sequence_to
, connect_by_root element_sequence_from AS root_sequence -- Changed
from element_hierarchy
start with element_type_from = [root_element_type]
and element_sequence_from = ( select [root_element_sequence] from all_root_elements )
connect by prior element_type_to = element_type_from
and prior element_sequence_to = element_sequence_from
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables, and the results you want from that data.
Explain how you get those results from that data.

Hyperion Business Rule Error: Cannot retrieve connected root element for

I have multiple computers set up on homesharing under one itunes account. Can I use face time on all of them or do i need seperate accounts for each?
I'd suggest you consider a cloud-based file sharing service such as Dropbox for this sort of use. iOS is not designed to be synched with more than one iTunes library at a time, so attempting to use it as you describe, connecting a single iPad to multiple computers, almost certainly won't work as you intend and is likely to cause nothing but headaches.

Need new spool for each Start_form
Hi all
I have a print program for RFFOAVIS. i have different orders spools shoould be like one spool for each order. but now i am seeing only one spool for all orders.
First Open_form, then I am calling the same for each order using start_form and end_form. then i am calling Close_form.
Though in Open_form i pass options tdnewid as 'x' or space i am seeing only one spool for all the orders.
but i need New spool for each order.

helpful answeres are surely rewardedHi Priyanka,
you have to 'X' the field TDFINAL in OPTIONS too.
Try this.

Select count(*) for each row of a table
Hello All,
Following query gives a statistics for each user (how many items he owns, home many tickets authored, how many objects he is subscribed to etc...)
select auser.userid,
(select count(*) from item where owner like '%' || auser.id || '%') ITEM_OWNER_CNT,
(select count(*) from tkt where originator = auser.id) TKT_ORIGINATE_CNT,
(select count(*) from tkt where assigned_to = auser.id) TKT_QA_CNT,
(select count(*) from tkt where create_user = auser.id) TKT_AUTHOR_CNT,
(select count(*) from subscriptions where subscriber_id = auser.id) SUBSCRIPTION_CNT
from
user auser
I was not happy with the performance of this query, so I tried the same using group by. The performance was even worse.
Is there any other option for me to try? Please advice.
Thanks,
SathishHi, Sathish,
As SBH said, a lot depends on your data. Please post some sample data (CREATE TABLE adn INSERT statemetns) for all tables, and the results you want from that data. Describe and give examples of any relationships that are not one-to-one..
You probably want to do joings, like SBH suggested, rather than scalar sub-queries.
The connection between the auser and item tables
(select count(*) from item where owner like '%' || auser.id || '%') ITEM_OWNER_CNT,is very suspicious. Perhaps the item table is poorly designed, and the query would be faster if that table were changed. Is changing the design of the item table an option?
You should be able to get all the information from the tkt table in one pass. It looks like you need to unpivot the data, so instead of one row per ticket (with 3 different people connected to it), there are 3 rows per ticket, each with only 1 person referenced. This is not necessarily a bad table design. Unpivoting, even more than most other things, depends on your database version, so you'll have to tell what version of Oracle you're using. -
I'm trying to get the count for each row to total count for each month
Something like this
Hardware | Jan
Monitors | 5
Processors | 137
Printers | 57
etc........
How can I write a query for this. I can get the Hardware column but don't know how to get the next column.If you can provide more data like sample input DML statements it would have been wonderful..
Assuming is , you need a pivot. Here is an article on basic Pivot..
http://sqlsaga.com/sql-server/how-to-use-pivot-to-transform-rows-into-columns-in-sql-server/
something like this may be..
DECLARE @Input TABLE
Hardware VARCHAR(20),
[Date] VARCHAR(20)
INSERT INTO @Input VALUES('Monitor', '01/01/2014'), ('CPU', '01/01/2014'), ('Monitor', '01/03/2014')
, ('ABC', '01/01/2014'),('Monitor', '02/01/2014')
;WITH CTE AS
SELECT Hardware, LEFT(DATENAME(M, [Date]),3) AS [MonthName] FROM @Input
SELECT *
FROM
SELECT Hardware, [MonthName], COUNT(Hardware) AS Count FROM CTE GROUP BY Hardware, [MonthName]) a
PIVOT (MAX([Count]) FOR [MonthName] IN ([Jan], [Feb])) pvt

For each row of a table call a pl/sql function
Hi,
i have a search form in adf like this:
parameter1:___
parameter2:____
buttonSearch
Table with results
field1 field2 field3
row1 ------ --------- -------
row2 ------ --------- -------
row3 ------ --------- -------
The user inputs the parameters 1 and 2 then press buttonSearch and the query execute and returns rows 1 to 3.
What i need is for each row call pl/sql function and passed the parameter 1 and 2 and field 1 to 3 (plsql function recives 5 parameters (parameter1, parameter2, field1 , field2 and field3) )
my buttonSearch call a java class that execute ExecuteWithParamters method.
I create the call to my plsql function on Application module class and then export as a java interface.
So i have the function to use in the viewcontroller layer, but i don't know where to use it, and how to pass the paramters: the parameter 1 and 2 that user inputs and the row fields.....
any ideas....
thanks!!Hi,
for this you need to call the PLSQL function upon table rendering, which means that you need a field in the table referencing a managed bean. In the managed bean you can use #{row} and resolve it using a ValueExpression. #{row} gives you access to the current rendered row (this is why you need to do it when the table renders) and thus allows you to call getAttribute(name) to get the values of field 1 - 3. The search field value you should get through the bindings reference (assuming the search form uses ADF). Then you create an operation binding for the executeWithParameters and call operationBindingName.getParamsMap().put(argname, argvalue); on it.
Frank
Ps.: I am concerned about the performance you get and wonder if it isn't possible to create a transient attribute that executes the function and displays the results. As I understand, the search parameters are only to filter the result set, which you still can do -
Check Box for each row in report -- all rows deleting when pressing DELETE
Hello experts! I have set up a report with a check box for each row. When I click the DELETE button to delete the selected rows, every single one of the rows get deleted...even the ones that are not selected. I have my process point set to "On Submit - After computations and validations".
This is my delete process (SHG is the table and SHG_ID is the primary key):
FOR i in 1..HTMLDB_APPLICATION.G_F01.count
LOOP
DELETE FROM SHG
WHERE SHG_ID = HTMLDB_APPLICATION.G_F01(i);
END LOOP;
Also, I've added to query in the region source this line:
htmldb_item.checkbox(1, SHG_ID) del,
Where does the "1" come into this? Not sure what I am doing wrong!
Message was edited by:

Message was edited by:
user477193The 1 (first argument to all the htmldb_item.* APIs) corresponds to the array number in htmldb_application.g_fNN. So 1 will populate array g_f01, 2 will populate g_f02 and so on.
Your code seems fine, it should delete only the checked rows. Are you sure there is no other process on the page that might be deleting the rows? See if you can put up an example on htmldb.oracle.com -
Prompting user for input for each row in the report
Is it possible to have a user entered field for each row in a report ?
ie. have a report with empolyee number, employee name, title, salary, and comment. Select of of these columns from the SQL query except for the comment, and then when the report is generated have the user be prompted for what the want the comment to be for every employee in the report?That is, have the user generating the report enter in a different comment for EACH employee. (ie Joe Smith's comment is "good worker and John Smith's comment is "come to work late on Tuesdays and Thursdays", Sally Jones' comment is "Expert in C++" etc.) as the reports is being built for each row returned from the query.

SQL merge and after insert or update on ... for each row fires too often?
Hello,
there is a base table, which has a companion history table
- lets say USER_DATA & USER_DATA_HIST.
For each update on USER_DATA there has to be recorded the old condition of the USER_DATA record into the USER_DATA_HIST (insert new record)
- to have the history of changes to USER_DATA.
The first approach was to do the insert for the row trigger:
trigger user_data_tr_aiu after insert or update on user_data for each rowBut the performance was bad, because for a bulk update to USER_DATA, there have been individual inserts per records.
So i tried a trick:
Instead of doing the real insert into USER_DATA_HIST, i collect the USER_DATA_HIST data into a pl/sql collection first.
And later i do a bulk insert for the collection in the USER_DATA_HIST table with stmt trigger:
trigger user_data_tr_ra after insert or update on user_dataBut sometimes i recognize, that the list of entries saved in the pl/sql collection are more than my USER_DATA records being updated.
(BTW, for the update i use SQL merge, because it's driven by another table.)
As there is a uniq tracking_id in USER_DATA record, i could identify, that there are duplicates.
If i sort for the tracking_id and remove duplicate i get exactly the #no of records updated by the SQL merge.
So how comes, that there are duplicates?
I can try to make a sample 'sqlplus' program, but it will take some time.
But maybe somebody knows already about some issues here(?!)
- many thanks!
best regards,
FrankHello

Adding a check box control for each row of data in a DataModel

I need to add a checkbox control for each row of data on a DataModel object.
I have a "commandButton" at the bottom of DataModel, and whenever someone checks some of the rows on that list of rows,
I need to get the selected dataModel(fragment of the list) in my backing bean.
How do I achieve this functionality in JSF?

Thanks,
Meghasyam.You'll want to have a wrapper class as suggested above, which has a "selected" boolean in it. Then use the "binding" attribute of the h:selectBooleanCheckbox component to bind the checkbox to that property... Make the property public and specify the properties exact name in the binding... bindings do not append "get" to the EL.
Here is an example of what your table might look like... This code would display the list of names with a checkbox to the left of each name... When the check box is selected, the "selected" property of that wrapper class is set to true or false as needed. Then when the form is submitted, and you are inside your actionListener or action method call, you can look through your collection of wrapper classes asking each one if it was selected or not... Then do whatever you want with them... In this example, replace "myBackingBean" with the name of your backing bean, and "names" with the name of the method in your backing bean which returns the collection of wrapper classes... create a flag "public boolean selected" or similar in your wrapper class..
<h:dataTable id="namestable"
value="#{myBackingBean.names}"
var="aName">
<h:column>
<h:selectBooleanCheckbox binding="#{aName.selected}"/>
<h:outputText value="#{aName.nameText}"/>
</h:column>
</h:dataTable>
Let me know if that isn't clear enough and I'll see if I can find a better way to explain it...

In a hierarchical query, is it possible for a row to have more than one immediate ancestor?
Hi
Question:
In a hierarchical query, is it possible for a row to have more than one immediate ancestor?
Answer:
No
No? Surely, it's yes?
Thanks,
JasonAs Frank pointed out already hierarhical most often means a tree (data structure) to deal with.
There must usually be just one boss (the root) in which case the answer is no.
Something to read: http://en.wikipedia.org/wiki/Tree_(data_structure)
You can find out Solomon spoke about a generalization therein.

Is there any way to make the formula variable take different values for different rows in a given report? Our requirement is that each sales division in US will be approved of a certain percentage of rebate that it can use. In the report one should see the net sales value after considering the % rebate. For e.g., US has East, West, South, Central and Midwest Sales Divisions. There are 5 product lines, prod1 to prod5. The client will maintain a Z table for all the combinations of Sales division and Product line (i.e., East & prod1 - 10%, East & prod2 - 3%... Midwest & prod5 - 5%). Actual sales done in each sales division will not have these rebates considered. So at the corporate level when the report is executed, the query should be able to apply the corresponding values to the actual sales. Is it possible with BEx? As far as I know, the user exit is not executed for each row. Hope I was lucid enough to explain the problem at hand and if anyone has any effective ideas on this issue, please post your thoughts here. Thanks a ton in advance.
ISHi,
I doubt that you'll be able to do it in BEx.
The easiest way is to include a rebate into your infoprovider.
