JPA: Complex query needed to load object / special processing on store

I have what I think is a tricky situation with an ORM scenario, and I am wondering what I need to do to get JPA to work with this situation:
I have a table that looks like:
key_with_rev_id INTEGER (sequence based, unique pk)
key_id INTEGER (sequence based)
rev_id INTEGER (sequence based, with key_id forms unique index)
del_flag VC(1)
+ various data fields
The object would contain these attributes (preferably):
key_id (as the "unique" id)
max_rev_id (transient, defaults to null)
+ various data attributes
When I load it -- for max_rev_id = null, it should basically do this:
select <data fields> from revved_table
where key_id = <object.key_id>
and rev_id = (select max(rev_id) from revved_table where key_id = <object.key_id>)
and del_flag is null or del_flag = 'N'
The query is a little more complex when max_rev_id is not null, but same idea.
Now then -- when I store the object, whether it is to insert or update, I want it to always insert rows, with the key_with_rev_id and rev_id values from the corresponding sequences. (On insert, it will also use another seq to populate key_id). When I delete, I also want to insert a new row, but set del_flag = 'Y'
Is this too complex for JPA such that it would be a huge hassle, or is there an elegant way to set this up?
My apologies for any unusual terminology in the above -- I am quite new to JPA.
Thanks,
ken clark

Does anyone have any suggestions as to where to start looking?
Thanks,
ken

Trying to form complex query - need help

I have a fairly complex query that I need to join the results of to show actual and goal by day. The actuals are an aggregation of records that get put in every day, while the targets are a single entry in range format indicating an active range for which the target applies. I'm working on a query that will put things together by month and I'm running into a snag. Can someone please point out where appropriate naming needs to go to get this to come together?
This one works:
(select DATE_INDEX, SUM(LDS) as TTLLDS, SUM(TONS) as TTLTONS from
    (select DATE_INDEX, VEH_LOC, SUM(LDS) as LDS, SUM(WT) as TONS from
       (select c.DATE_INDEX, c.VEH_LOC, COUNT(j.LOAD_JOB_ID) as LDS,
             CASE WHEN SUM(w.SPOT_WEIGHT) = 0 THEN SUM(j.MAN_SPOT_WT)
                  ELSE SUM(w.SPOT_WEIGHT)
              END as WT
          from TC c, TC_LOAD_JOBS j, LOAD_RATES r, SPOT_WEIGHTS w
         where c.TC_ID = j.TC_ID and j.LOAD_RATE_ID = r.LOAD_RATE_ID
           and c.DATE_INDEX = w.DATE_INDEX and j.LOAD_RATE_ID = w.LOAD_RATE_ID
           and c.VEH_LOC in (select ORG_ID from ORG_ENTITIES where MNG_ORG_ID = 200)
           and c.DATE_INDEX between to_date('08/01/2010','MM/DD/YYYY') and to_date('07/31/2011','MM/DD/YYYY')
         group by c.DATE_INDEX, c.VEH_LOC
        union
        select c.DATE_INDEX, c.VEH_LOC, COUNT(j.JOB_ID) as LDS,
             DECODE(SUM(j.AVG_SPOT_WEIGHT),0,SUM(r.BID_TONS),SUM(j.AVG_SPOT_WEIGHT)) as WT
          from TC_3RDPARTY c, TC_3RDPARTY_JOBS j, LOAD_RATES r
         where c.TC_ID = j.TC_ID and j.LOAD_RATE_ID = r.LOAD_RATE_ID
           and c.DATE_INDEX between to_date('08/01/2010','MM/DD/YYYY') and to_date('07/31/2011','MM/DD/YYYY')
           and j.FACTORY_ID in (select ORG_ID from ORG_ENTITIES where MNG_ORG_ID = 200)
         group by c.DATE_INDEX, c.VEH_LOC)
      group by DATE_INDEX, VEH_LOC)
group by DATE_INDEX)Now I need to add in the following query:
select (u.MACH_TPH_D+u.MACH_TPH_N)/2 as MTPH_TGT, (u.LABOR_TPH_D+u.LABOR_TPH_N)/2 as LTPH_TGT
     from UTIL_TARGET_LOADERS u
    where u.ORG_ID in (select ORG_ID from ORG_ENTITIES where MNG_ORG_ID = 200)The join needs to be based on VEH_LOC and DAY in the form:
   ... WHERE u.ORG_ID = x.VEH_LOC
          AND x.DATE_INDEX between u.START_DATE and NVL(u.END_DATE,sysdate)I had one that worked just fine when only one entity was involved; the complication arises in that this is a division-level report so I have to individually resolve the subordinates and their goals before I can aggregate. This is one of two queries I need to tie together using a WITH clause so I can pivot the whole thing and present it in month-by-month fashion. When I try to tie it together like the query below, I get: invalid relational operator.

              END as WT
          from TC c, TC_LOAD_JOBS j, LOAD_RATES r, SPOT_WEIGHTS w
         where c.TC_ID = j.TC_ID and j.LOAD_RATE_ID = r.LOAD_RATE_ID
           and c.DATE_INDEX = w.DATE_INDEX and j.LOAD_RATE_ID = w.LOAD_RATE_ID

      and ttls.VEH_LOC = u.ORG_ID
group by ttls.DATE_INDEXI know this is a nested mess, as it has to grab the production from two tables for a range of VEH_LOC values and sum and aggregate by day and VEH_LOC, then I have to try and match that to the targets based on VEH_LOC and day. My final query is to aggregate the whole mess of sums and averages by month.
I'd appreciate it if someone can point me in the right direction.

Figured it out.

Complex Query - Need Solution

Hello,
I am having trouble in getting the result at the bottom. I have two tables as below. I need Idno,transdt,cycdt,amt from joining two tables.
The criteria is that if the transdt greater than same month of cycdt then we need get the next month cycdt and corresponding amount for that, if it is less than or equal to same months cycdt then get the same months cycdt and amt.

Regards,

First thing that i notice in this query is you are Using Distinct as well as Group by.
Your group by will always give you distinct results ,then again why do you need the Distinct?
For example
WITH t AS
     (SELECT 'clm1' col1, 'contract1' col2,10 value
        FROM DUAL
      UNION ALL
      SELECT 'clm1' , 'contract1' ,10 value
        FROM DUAL
      UNION ALL
      SELECT 'clm1', 'contract2',10
        FROM DUAL
      UNION ALL
      SELECT 'clm2', 'contract1',10
        FROM DUAL
      UNION ALL
      SELECT 'clm3', 'contract1',10
        FROM DUAL
      UNION ALL
      SELECT 'clm4', 'contract2',10
        FROM DUAL)
SELECT distinct col1,col2,sum(value) from t
group by col1,col2Is always same as
WITH t AS
     (SELECT 'clm1' col1, 'contract1' col2,10 value
        FROM DUAL
      UNION ALL
      SELECT 'clm1' , 'contract1' ,10 value
        FROM DUAL

How to store data from a complex query and only fresh hourly or daily?

We have a report which runs quite slow (1-2 minutes) because the query is quite complicate, so we would like to run this query daily only and store in a table so for those procedures that need to use this complex query as a subquery, can just join to this table directly to get results.
However, I am not sure what kind of object I should use to store data for this complex query. Is data in global temp table only persist within transaction? I need something that can persist the data and be access by procedures.
Any suggestions are welcome,
Cheers

Thank you for your reply. I looked at the materialized view earlier on, but have some difficulties to use it. So I have some questions here:
1.The complex query is not a sum or aggregate functions, it just need to get data from different tables based on different conditions, in this case is it still appropriate to use meterialized view?
2.If it is, I created one, but how to use it in my procedure? From the articles I read, it seems I can't just query from this view directly. So do I need to keep the complex query in my procedure and how the procedure will use the meterialized view instead?
3. I also put the complex query in a normal view, then create a materialized view for this normal view (I expect the data from the complex query will be cache here), then in the procedure I just select * from my_NormalView, but it takes the same time to run even when I set the QUERY_REWRITE_ENABLED to true in the alter session. So I am not sure what else I need to do to make sure the procedure use the materialized view instead of the normal view. Can I query from the Materialized View directly?
Below in the code I copied from one of the article to create the materialized view based on my normal view:
CREATE MATERIALIZED VIEW HK3ControlDB.MW_RIRating
PCTFREE 5 PCTUSED 60
TABLESPACE "USERS"
STORAGE (INITIAL 50K NEXT 50K)
USING INDEX STORAGE (INITIAL 25K NEXT 25K)
REFRESH START WITH ROUND(SYSDATE + 1) + 11/24
NEXT NEXT_DAY(TRUNC(SYSDATE), 'MONDAY') + 15/24
enable query rewrite
AS SELECT * FROM HK3ControlDB.VW_RIRating;

Object not found in store error when trying to load MimeContent of an email (containing attachments)

This is a weird one and I'm hoping someone can reproduce this and give me some help.
We have a system that uses the EWS Managed API to send emails. Optionally an email may need to be saved out as an rfc822 (.eml) file afterwards for storing in our own database. In order to save to a file I need to load up the MimeContent of the message.
And this is where an "Object not found in store" exception can get thrown.
The really strange part is that the exception only seems to occur if the email contains an attachment and if there is too much of a delay between sending the email and trying to access the MimeContent!
My test code is something like:
// Set up the basics
_item = new EmailMessage(P7ExchangeService.Service);
_item.Subject ="Hello world";
_item.ToRecipients.Add("some name", "[email protected]");
_item.Body = new MessageBody(BodyType.HTML, @"<html><head></head><body>hello world<image src=""cid:blah""/></body></html>");
// Add attachment
FileAttachment att = _item.Attachments.AddFileAttachment("blah", "c:\temp\blah.jpg");
att.IsInline = true;
att.ContentId = "blah";
// Send and save
_item.SendAndSaveCopy();
// Wait a bit (see comments below)
Thread.Sleep(5000);
// Now try and save out
var propCollection = _item.GetLoadedPropertyDefinitions();
propCollection.Add(ItemSchema.MimeContent);
_item.Load(new PropertySet(propCollection)); // EXCEPTION!
// ... etc
On some systems it seems that the sending can take a while, hence my Thread.Sleep() call to simulate this.
Its when I try and load up the MimeContent that I will then get the exception. But ONLY if I sleep (simulating the occasional delay seen on customer sites) and ONLY if the email contains an attachment.
The mimecontent is necessary in order to save out to a file (by accessing the _item.MimeContetn property).
Can someone please explain the exception and/or provide a better way of doing this??

This is normal EWS doesn't return the Id of the Item in the SentItems Folder so you need to use a workaround like
http://blogs.msdn.com/b/exchangedev/archive/2010/02/25/determining-the-id-of-a-sent-message-by-using-extended-properties-with-the-ews-managed-api.aspx .
If you want to understand the issue you can enable tracing and look at responses, the actually Id your trying to load the MimeContent from is probably the Id of the draft message. Eg to send a message via EWS with attachments multiple operations must be
used to construct it and when the messages finally gets sent the copy in the drafts folder is deleted and a copy is created in the SentItems folder. However the Id isn't returned for the SentItems copy hence you need the workaround.
Cheers

How to create an explain plan with rowsource statistics for a complex query that include multiple table joins ?

1. How to create an explain plan with rowsource statistics for a complex query that include multiple table joins ?
When multiple tables are involved , and the actual number of rows returned is more than what the explain plan tells. How can I find out what change is needed in the stat plan ?
2. Does rowsource statistics gives some kind of understanding of Extended stats ?

You can get Row Source Statistics only *after* the SQL has been executed. An Explain Plan midway cannot give you row source statistics.
To get row source statistics either set STATISTICS_LEVEL='ALL' in the session that executes theSQL OR use the Hint "gather_plan_statistics" in the SQL being executed.
Then use dbms_xplan.display_cursor

Need Help Loading SWF in a FLA

I simply want to call a swf into an existing fla. I have
tried everything. When dragging the timeline, you see the swf. When
you preview, it is not there. Background - I have an exisiting fla
that contains the image background for all. I want to set a
transparent carousel menu on top of the background that is in the
fla and leave the existing background and lower objects in place.
The carousel.swf will need to call java and an xml file on the web
server.....all external to the "summed" final. If I could layer
flashed in DW, then the problem would also be solved. Please be
detailed, I am obviously not a developer.

although I'm not certain why you would not just 'place' the
background 'image' on the stage in the fla (probably because you
wish to change it dynamically down the road) - you need to 'load'
the swf, not 'place' it within the other file. you do this with the
MovieClipLoader class.
with the swf that you wish to load in the same directory as
the swf of the carousel file, place something like the following in
the first frame, on a layer called actions, in the actions panel:

Complex query

I am novice in PL/Sql. I need some help in writing a complex query.
I imagine the following table structure.
Type(string) Date(date) count(int)
Given a date range
The query needs to group the records on type and return the record (type and count) which has the max date (its just date, no time is involved) for each group (which is based on type) . If there are more than one records which have the max date then the average count should be returned for that type
i would be glad if someone could give any ideas as to how to go about this query. Thanking you in advance.
regards.

Heres the query ... Forget the period .... wht this query is supposed to do is group on assigned ki for a given date range. then it has to get the value which is for the last record for that Ki in the date range. If there are 2 records which have max date then it should give an average.
e.g
assignedKI / date / value
a 1st may 2008 10
b 2nd may 2008 12
c 1st may 2008 13
a 30 - apr-2008 16
b 4th may 2008 17
a 1st may 2008 20
The query should return
a 1st may 2008 15 (which is the average as there are 2 values for the max date for a)
b 4th may 2008 17
c 1st may 2008 13
the following query doesnot work ....
SELECT
kiv2.assigned_k_i,
kiv2.ki_name,
kiv.period,
max( kiv2.ki_value_date) ,
avg(kiv2.ki_value)
FROM
SELECT
assigned_k_i,
period p1,
TO_CHAR(ki_value_date, period) period,
MAX(ki_value_date) ki_value_date
FROM
v_ki_value,
(select ? period from dual)
WHERE
(status = 'APPROVED' OR status = 'AUTOAPPROVED')
AND ( trunc(to_date(to_char(ki_value_date, 'DD/MM/YYYY'), 'DD/MM/YYYY')) >= ?)
AND ( trunc(to_date(to_char(ki_value_date, 'DD/MM/YYYY'), 'DD/MM/YYYY')) <= ?)
AND (INSTR(?, TO_CHAR(assigned_k_i)) > 0)
GROUP BY
assigned_k_i,
TO_CHAR(ki_value_date, period)
) kiv,
v_ki_value kiv2
WHERE
kiv.assigned_k_i = kiv2.assigned_k_i
AND to_char(kiv.ki_value_date, kiv.p1) = to_char(kiv2.ki_value_date, kiv.p1)
GROUP BY
kiv2.assigned_k_i,
kiv2.ki_name,
kiv.period,
kiv2.ki_value
ORDER BY
kiv2.assigned_k_i

Complex Query in toplink descriptor

I have a complex query with "Order by" and "Max" aggregation function and I am trying to convert it to a named query. I am using toplink descriptor in Jdeveloper 11G.
1. Is it possible to write a named query which returns values from more than two different table?
2. how to specify Max operation in the Toplink descriptor.
Here is my Query
select * from table1 t1 ,table2 t2
where
t1.id = t2.id and
t1.name ='Name' and
t1.status<>'DELETE' and
t2.a_id = (select max(a_id) from table2 t21 where
t21.a_id = t1.id and
group by id)

TopLink supports sub-selects through sub-queries in TopLink Expressions, and through JPQL. I'm not sure on the JDev support though, you may need to use a code customizer or amendment to add the named query.

EJB-QL--- Complex Query --- Two Entites

hi
Can i write Complex Query in EJB-QL
between two entities...
have any buddy wrote the same....
i badly require the same...
bye
RAJ

Raj -- OC4J will support EJB-QL soon but not yet. You can look at
Re: Data Integrity
for more details.
Now, as for complex query, you may still be able to do this in the current version through the orion-ejb-jar.xml. You can
include complex SQL there in the finder methods.
What exactly do you need to do?
later -- Jeff
