Tree query issue

Good morning,
Obviously, I simply do not understand the query that gets constructed to create a Tree structure in APEX. I have a Tree in Oracle Forms that works correctly. I cannot, however, seem to get it to port over to APEX.
In my table (a table of contents type of structure), I have 3 columns that govern where in the list an item falls. TOC_LEVEL (1 a parent-level entry, or 2 child-level entry), TOC_PARENT, what parent a child entry is associated with, and TOC_SEQ_ID, where in the list an item should be placed.
So, I might have entries like this:
TOC_LEVEL TOC_PARENT TOC_SEQ_ID
1 NULL 1
2 1 50
2 1 60
1 2 2
1 3 3
2 3 50 - dups here don't matter because it would fall under a different parent...
2 3 75
and so-on.
The query that I use in my Form is this:
select decode(level,-1,-1,-1),
level,
toc_description,
toc_entry_type,
toc_id
from toc where state_id = '&State_ID'
start with toc_level = 1
connect by prior toc_seq_id = TOC_Parent
and prior State_ID = '&State_ID'
order by to_char(toc_parent) || to_char(toc_seq_id)
and this works. I am able to display and retrieve the appropriate data.
I can NOT seem to get this or any variation to work within APEX.
The closest I have come is that I retrieve all of the parent-level entries, but retrieve the very same child-entries under each parent. And when I click the '+' on one parent, ALL parents expand... and the '-' colapses all parents, not just the one I clicked.
What is it that I am missing here?
Thanks,
Don

Hi Don,
The value for the hidden Pn_TREE_ROOT should be the id of the topmost item in your tree. If you have more than one that could be topmost, then you have to create a dummy root - this was described in the linked thread - and the ID of the dummy root should be used.
So, in your example, if more than one toc_parent entry can contain null, you have more than one root so must create a dummy root. If only one toc_parent entry contains null, then the ID of this record must be specified as the root.
The only thing you may have to do from the linked example, would be to convert the nulls for your actual pid values into 1 to get them to link to the new dummy parent.
So:
select 1 id, null pid, 'Rootname' name, null link, null a1, null a2 from link
union all
select
toc_level+1000000 id,
case when toc_parent is null then 1 else toc_parent+1000000 end pid,
toc_description name,
null link,
null a1,
null a2
from toc where state_id = 'ZZ';This creates a dummy root with an id of 1 and attaches all of your actual parents to this root. The actual ID values have to be increased to ensure that none of them could be a 1 and become attached to the root.

Dataset query issues twice if the dataset is connected to matrix and used in multilookup function

hello everybody.
could not find any information if this is an intended behavior:
dataset query issues twice if the dataset is connected to matrix and used in multilookup function

Hello, Wendy.
I prepared a very empty sample report for you to demonstrate the problem - with this report, i hope, there is no place to discuss the shrinking of time data retrieval.
There is one dataset, one parameter and one lookup function. The query is executed twice.

Calling boolean function from tree query

Hi all,
I have placed a tree on my sidebar region from the following query
select PAGE_NO id,
PARENT_PAGE_NO pid,
NAME name,
'f?p=&APP_ID.:'||page_no||':&SESSION.' link,
null a1,
null a2
from #OWNER#.APEX_PAGES
WHERE page_no = :APP_PAGE_ID
AND nvl(navigation,'N') = 'Y'
Its running perfectly fine. Now i have my custom function "isUserAllowed(app_user, name_of_node, isParent)" which returns a boolean expression is the logged in User has access privilege on that node.
How can i run my function inside the tree query so that node is visible only for those values in which my function returns "true"? and not on others?
With Regards,
Sunil Bhatia

The "wrapper" function would actually be pretty easy - just another function to call the one returning the boolean and convert it to some other value, numeric or character. something like (untested)
<pre>
FUNCTION wrapper_function(P_whatever varchar2) return varchar2 IS
v_return_value_c varchar2(5);
BEGIN
r_return_value_c := case boolean_function(p_whatever)
when true then 'true'
else 'false;
return v_return_value_c;
END;
</pre>
Using the function in the WHERE clause could look something like this (untested, but should work if done correctly)
<pre>
select whatever
from your_table
where wrapper_function(whatever) = 'true'
</pre>

Web Query issues

Hi All,
I have created a web query and assigned it to a role. I have moved the role, web templete and the query from dev to QA was able run the query fine without issues.
The problem I am having is when I make changes to the query and transport it to QA...when I run the query from the role menu it still shows the old query instead of the changed query.
Can someone please explain what are the steps I need to take when I make changes to exsisting web query in dev and move to QA and be able to see the changes. What are all the objects I need to collect. Also would like to know if there are any settings on the role menu or web templete that need to be changed and also any buffers that I need to cleared??
Any help is appriciated and will give max points.
Thanks

BWdesi,
please avoid reposts - it could be that due to network issues the post got posted twice... close one of them as answered and then proceed with the other one...

can u plz tell me how to slove this
regards
raju

Dear Raju,
In the query, for the Calculated Key Figure (Amount)
   Select properties, enhanced and change to:
                      "BEFORE AGGREGATION"
It seems to be doing after aggregation, which is default.
it is aggregating:
    price = 5+10 = 15
    qty   = 5+5 = 10
    Amount = 15 * 10 = 150
Good luck, BB

Physical query issued by Obiee when cache is on is different and slow

When the same report runs in OBIEE 10g and cache is OFF it takes less then 1min to get results. If cache is turned ON physical query issued by Obiee is totally different and it takes 2h to get results. Has anyone experienced this with having cache on that some queries are performing poorly.
Thanks,
Tatjana

We are using BI Apps Order Management and Fulfillment Analytics and all tables are cached anyway. Dimensions used are not that huge up to 40K rows. What should I check when it comes to DB query? As I said is different than one generated when cache is disabled although both have the almost the explain plan.

SQL query issue

I am attempting to connect to a Progress database using JDBC and am having a few issues with my SQL statement. The code concerned looks like this:
// Get a statement from the connection
Statement stmt = conn.createStatement() ;
// Execute the query
ResultSet rs = stmt.executeQuery( "SELECT * FROM pub.cust" ) ;
// Loop through the result set
while( rs.next() )
System.out.println( rs.getString( "cust-code" ) ) ;
That works just fine. Prints out each of the cust-code values. My issue comes when I try to refine the query to be:
ResultSet rs = stmt.executeQuery( "SELECT * FROM pub.cust WHERE cust.Cust-code='100001-0'" ) ;
or even
ResultSet rs = stmt.executeQuery( "SELECT Cust-code FROM pub.cust" ) ;
Both of these give me an error saying Column not found/specified.
if I wrap Cust-code in single quotes, the script prints Cust-code on each line, not the value for it. If I escape Cust-code like Cust\-code, I get an Illegal escape character. Any ideas?

I have never used Progress, but maybe you have to fully qualify the field names like this:
ResultSet rs = stmt.executeQuery( "SELECT * FROM pub.cust WHERE pub.cust.Cust-code='100001-0'" ) ;
ResultSet rs = stmt.executeQuery( "SELECT pub.cust.Cust-code FROM pub.cust" ) ;Just a thought.

Help needed in resolving query issue

Hello all,
Would appreciate any help on the following issue.
Our process has a stored procedure, which used to take 6 mins to run.
We are not sure what changed at what level, but now the query goes on forever( till database shuts down or we kill it), and never returns any result. Also, this is not consistent at all times. Sometimes(!!), it brings back results in expected time.
Apparently nothing changed in the database.
We checked and the query where it gets stuck is as follows:
select a.x,
b.y,
c,z
from a,b,c where
b.header_id =a.header_id and c.property_id =a.property_id(+) and b.status_id in (1,0) and a.date(+)>c.date;
It does not give any error or any mesg, when it reaches this query, and just hangs in there( Mind this was a working query since last 2 months)
We are at a total loss at the inconsistent behaviour of this.
Any help or advise would be greatly appreciated
Thanks

Oracle Sql Query issue Running on Different DB Version

Hello All,
I have come into situation where we are pruning sql queries on different DB version of Oracle and have performance issue. Let me tell you in brief and i really appreciate for your prompt response as its very imperative stuff.
I have a query which is running on a DB of version 7.3.4 and it takes around 30 mins where as the same query when run on 8i it takes 15sec., its a huge difference. I have run the statistics to analyze on 7.3 and its comparatively very high. Question here is, the sql query trys to select data from same schema table and 2 tables from another DB using DB link and 2 other tables from another DB using DB link.So,how can we optimize this stuff and achieve this run as same time as 8i DB in 7.3. Hope i am clear about my question, Eagerly waiting for your replies.
Thanks in Advance.

Difficult to be sure without any more detailed information, but I suspect that O7 is in effect copying the remote tables to local temp space, then joining; 8i is factoring out a better query to send to the remote DBs, which does as much work as possible on the remote DB before shipping remaining rows back to local.
You should be able to use EXPLAIN PLAN to identify what SQL is being shipped to the remote DB, If you can't (and it's been quite a while since I tried DB links or O7) then get the remote DBs to yourself, and set SQL_TRACE on for the remote instances. Execute the query and then examine the remote trace files, And don't forget to turn off the tracing when you're done.
Of course it could just be that the CBO got better,,,
HTH - if not, post your query and plans for the local db, and the remote queries.

Adhoc query Issue in IT0001- Additional fields.

Hi Everyone,
Im facing issue in adhoc query, In IT0001- Additional field .The supervisor name is not getting displayed in the output even though personnel number is getting fetched.Output value attributes is chosen as 'value and text'.
Details of the field:
Name of the field: Personnel number of superior (Org. Manag
Technical name :SYHR_A_P0001_AF_OMNGR_NR (Additional field)
This is happening after the implementation of A3 to A9 notes.
Thanks in Advance.
Regards,
S P Joshi.

Did you try Ted's solution of identifying the "addtional field 'SYHR_A_P0001_AF_OMNGR_NA' "as a displayed field ?
Note that if that field is not already in your Info-Set, you will have to add it (using t-code sq02).

Tabular model with Direct Query issue

Hi,
i am creating a tabular model - Direct Query option. I am using a kind of below query to import data,
Declare @TEST as Table (TestID int, TestName varchar(20))
Insert into @TEST
Select 1, 'TEst1' Union
Select 2, 'TEst2'
Select * from @TEST
But the Import fails with an error similar to below,
OLE DB or ODBC error. An error occurred while processing the partition 'Query_``````````' in table 'Query_````````'. The current operation was cancelled because another operation in the transaction failed.
Any idea, why it is failing ? or is it like we shouldn't use declare statement in the Query area ?
Please reply ...Thanks in advance !
--------------------------- Radhai Krish | Golden Age is no more far | --------------------------

I'm pretty sure that the query would have to be a single statement so the declare statement would be causing issues.
So just doing this as a single union query should work:
Select 1 as TestID, 'TEst1' as TestName Union
Select 2, 'TEst2'

Hi Sanjay,
You have mentioned "+but its give me error in SQL Workshop > Script Editor window+" - are you referring to the SQL Workshop > SQL Scripts > Script Editor option, while editing a SQL script? If so, then I have been unable to reproduce the behaviour you have reported, and have not received any errors using your test query.
To assist in identifying the cause of your problem, could you please outline the exact steps that you followed, leading up to the step where you receive an error?

Hilary

Af:query issues within a taskflow

JDev: 11.1.2.1
I've created a simple fusion app, using the HR countries and department tables. The ViewController contains a home page and a taskflow.
The taskflow accepts a 'SearchBy' parameter, and I have a router (default) which then redirects the user to one of two pages, based on that parameter.
<case id="__1">
<expression>#{pageFlowScope.SearchBy eq 'countries'}</expression>
<outcome>countries</outcome>
</case>
<case id="__2">
<expression>#{pageFlowScope.SearchBy eq 'depts'}</expression>
<outcome>depts</outcome>
</case>
The two pages "CountriesQueryPage" and "DeptsQueryPage" contain nothing more than a standard af:query (with table) based on the named criteria "All Queriable Attributes" for respective views.
The Home page contains the taskflow above as a region, and a couple of links, which set a #{requestScope.SearchBy} parameter. The taskflow binding was changed to Refresh 'ifNeeded'.
<af:panelHeader text="panelHeader 1" id="ph1">
<f:facet name="context"/>
<f:facet name="menuBar"/>
<f:facet name="toolbar">
<af:group id="g1">
<af:commandLink text="Countries" id="cl1" partialSubmit="true">
<af:setPropertyListener from="#{'countries'}" to="#{requestScope.SearchBy}"
type="action"/>
</af:commandLink>
<af:spacer width="10" height="10" id="s1"/>
<af:commandLink text="Depts" id="cl2" partialSubmit="true">
<af:setPropertyListener from="#{'depts'}" to="#{requestScope.SearchBy}"
type="action"/>
</af:commandLink>
</af:group>
</f:facet>
<f:facet name="legend"/>
<f:facet name="info"/>
<af:region value="#{bindings.tf11.regionModel}" id="r1" partialTriggers="::cl1 ::cl2"/>
</af:panelHeader>
When I run this, the default "countries" page is displayed in the region. The af:query functions perfectly. When I click the link to the Depts page, the region refreshes as expected, but when the query table is rendered an error is thrown "Content failed to load.... data transmission was interrupted. Checking the log, I'm getting....
<LifecycleImpl> <_handleException> ADF_FACES-60098:Faces lifecycle receives unhandled exceptions in phase RENDER_RESPONSE 6
java.lang.IllegalStateException: Could not find component to stream
<FaceletViewHandlingStrategy> <handleRenderException> Error Rendering View[Home]
java.lang.IllegalStateException: Could not find component to stream
Couldn't find much online about this error message.
The only way I've been able to stop the issue is to remove the af:table on the depts query page.
I also tried using a dynamic region to get the above functionality (dividing each query page into it's own taskflow and removing the router) and got exactly the same issue.
Any ideas?
Thanks

Just in case anyone else has this issue -:
It turns out that the fault was using RequestScope parameters within the af:setPropertyListener. Once I changed this to a longer scope, pageFlowScope for example, the issue was resolved.
