Date comparison exception

Greetings, I've got an object like the following:
java.sql.Date fromDate;
java.sql.Date toDate;
direct-to-field mapped to an oracle table like:
FROM_DATE DATE
TO_DATE DATE
When I try to query using the following expression I get:
Expression exp = new ExpressionBuilder().get("toDate").
greaterThan(new ExpressionBuilder().get("fromDate));
//... query stuff.
6406 17 May 2004 09:38:24,157 ERROR (DataClientSession.java:334) Error performing query. Nested exception is:

What am I doing wrong?
thanks,

Hi Keith,
What was the problem in the end?
I have been using the following without problems:
ExpressionBuilder builder = new ExpressionBuilder();
Expression whereClause = builder.get("modifiedDate").greaterThan(builder.get("createdDate"));
I did notice that in the 9.0.4.1 release for toplink that it mentions:
OracleAS TopLink now maps the database types DATE and DATETIME to java.util.Calendar for descriptor generation. In previous versions, DATE and DATETIME types were mapped to java.sql.Date.

OBIEE Date Comparison report with multiple measures

Hello everyone...
I have a requirement where I need to create a date comparison report (Current Month vs. Prior Month vs Prior Month Year Ago vs YTD vs Prior YTD vs Rolling 3 months, etc) with multiple Measures (Quote count, Quote offered count, New Business count, etc). I am to generate this report in this fashion:
Quotes Current Month vs PM vs YoY Prior
Month Current Month Prior Year Current
YTD vs PM Prior
YTD Rolling 3 Months vs PM Prior Rolling 3 Months
Issued 120 120 123 1400 1020 1700 1580

I understand that time series is an option, and have created the time series (which show up as measures).
My problem is:
when creating the report (even as a pivot table) , OBIEE is not allowing me to drag the measure to rows, nor is it allowing me to drag the time series to columns. Also, I need to do conditional formating on some of the columns showing an up arrow for increased vs. prior month and down arrow for decreased vs. prior month.
Does anyone have a solution for this issue? Any assistance would be greatly appreciated...
Please advise and thanks!!!

Jason,
You've been very helpful, but I guess I'm just not explaining myself that well. The Credit Memo's throw things off because they do not contain a "Paid Date" value. That field in the record is blank. Since it is blank the report query ignores them. Therefore when the report query returns all records that have a "Paid date" range of "x to y" they are never returned. This is a problem whenever a credit memo exists for an invoice because the "invoice total" never changes. So when a customer pays on their account for a particular invoice, they only pay what is due which is the "invoice total" minus any "credit" from the "Credit Memo". So when my A/R person receives payment they are showing the invoice paid in full because MAS automatically includes all invoices and credit memo's. My report does not because there is no data in the "Paid Date" field of the record for Credit Memos.
I've been doing alot research in trying to resolve this "exception" to my report. I think I may be on to something, but my knowledge of arrays is extremely limited. My resolution involves populating an array with the "invoice numbers" that are returned from the initial query from the supplied date range. Then using the "invoice numbers" from the array have it then populate my details section of the report with all of "invoice records" both the actual invoice record and any "credit memo" records. I can then group the records returned based upon the "invoice number". then within that grouping I can performing my calculations to show whether or not the invoice has been paid in full. What do you think? I've been able to populate an array with the invoice numbers based upon my date search range, but I have yet to figure out how to take that information and perform another lookup to pull in the rest of the data I need. Do you have any ideas?
Thanks. Bill

So if I do something as follows in my stored proc, I do not have to check for NO_DATA_FOUND?
OPEN my_CuRSR FOR
SELECT DISTINCT blah blah blahmy_cursr is what I am returning as OUT param in my SP.Correct. At the point you open the cursor, oracle has not attempted any 'fetch' against the data so it won't know if there is any data or no data. that only occurs when a fetch is attempted.

IR report - No Data Found exception

Hi,
I have created one IR report in apex. I need to get the no data found exception on this report i.e. if user enters some search keywords and he is getting no data in that case want to store the searched keywords in the database for future reference that there is no data for such search criteria.
Could anyone help me to catch the no data found exception and executing a pl-sql process for fetching the search criteria ?
Thanks in advance!

I have created an IR report based on collections. But still I am not able to understand where I can write a code for EXCEPTION NO_DATA_FOUND. The pl-sql code used to create a collection which we write in before header process and the actuall IR report which is build using SQL query on collection so where can I put the exception code?
What I want is to catch no data found exception when user types something in IR report search bar and gets nothing as a search result. Can you please help me on this?
Thanks,
Punam

No Data Found Exception in bulk updates

I am trying to catch no data found exception in bulk updates when it does not find a record to update in the forall loop.
OPEN casualty;
LOOP
FETCH casulaty
BULK COLLECT INTO v_cas,v_adj,v_nbr
LIMIT 10000;
FORALL i IN 1..v_cas.count
UPDATE tpl_casualty
set casualty_amt = (select amt from tpl_adjustment where cas_adj = v_adj(i))
where cas_nbr = v_nbr(i);
EXCEPTION WHEN NO_DATA_FOUND THEN dbms_output.put_line('exception')
I get this error at the line where i have exception:
PLS-00103: Encountered the symbol "EXCEPTION" when expecting one of the following:

close current delete fetch lock insert open rollback
savepoint set sql execute commit forall merge pipe
Can someone pls direct me on how to get around this?
If I do not handle this exception, the script fails when it attempts to update a record that does not exist and the error says : no data found exception.
Thanks for your help.
Edited by: user8848256 on Nov 13, 2009 6:15 PM

No Data Found isn't an exception raised when an UPDATE cannot find any records to process.
SQL%ROWCOUNT can be used to determine the number of rows affected by an update statement, but if 0 rows are updated then no exception will be raised (it's just not how things work).
If you post your actual CURSOR (casualty) declaration, it's quite possible we can help you create a single SQL statement to meet your requirement (a single SQL will be faster than your current implementation).
Have you looked in to using the MERGE command?

Hi Friends
I am trying to execute an SQL SELECT stmt inside a PL/SQL block. But when i execute the procedure, it gives me No Data Found Exception.
I know it is because no row is fetched in the query, but the condition of the SELECT query i have specified is being satisfied, i have checked it by running it on the SQL prompt.
But somehow, it is not running from inside the PL/SQL procedure.Can anybody help me out on this as to why is this happening?? I am giving my code for reference and have Highlighted the Query inside it:

Idoc data comparison between different R/3 clients.

Hi ppl ,
Is there a way idoc comparison can be done between different clients without going
by Segment by Segment comparison ?
I have a requirement wherein i have thousands of idocs in QA system and i need to
compare those with the ones in PROD system. The segments in the idocs may vary
depending on the data that flows from the third party system which will post idocs in R/3.
So, the segment wise comparison of data is also ruled out .
Do we have any standard reports which will help in achieving this purpose ?
Please let me know how the idoc data comparison can be carried out .
Regards,
Nick.

Hi Nick,
There is no standared tools available for comparing the data of two idocs.
By using beyond compare s/w you can check the data, but the thing is you have to download the idoc data to file format.
By using Idoc_xml_transform function module you can download idoc data to xml format, after you can compare.
Check this

Time "and" Date Comparison

Hi,
I am trying to get the difference between two sets of time.
This also involves a Date comparison because sometimes the times span more than one day.
Here is an example of what I'm trying to accomplish. I have searched the forum archives but have not yet found time and date comparisons together.
startRun = "10/26/01 4:30 PM";
endRun = "10/27/01 7:45PM";
I want to process these two times and get the difference.
The result would be:
totalRunTime = "27 hours 15 minutes";
I am stumped. Is this type of process even possible? Any help would be grealty appreciated.

I never miss class....my instructor gave us the assignment of making a heap sort and he told us to use code off the internet as a resource because the only sorting we have done so far is bubble.....this was a research project, for my instructor to see if we can use the internet as an effective resource to put together a program and learn about a differnet type of sorting.....everyone in the class got a different type of sort (merge, quick, insertion, etc...). i have put the program together and customized it to my needs based on my knowledge.....the last thing i am having trouble with is my counting of comparisons and data movements. Can you please help me finish up my program.

Question on How to Use LI and NP Data Comparison Report

Hi,
We are trying to figure out how to make the Transaction Code PC00_M42_LLPD (LI and NP Data Comparison Report) work. What file type (.xls, .txt, etc) should be used? Anyone who is familiar with the transaction, please help.
Best Regards,
Bry

Somewhere in the Oracle 8.0 documentation it is stated that one
enviroment per each thread is required if I want to ensure
complete concurrency of different threads accessing databases.
But isn't this a waste of resources since only Handle Alloc &
Free functions use Enviroment handle, hence they should be
mutexed for access from concurrent threads.
But the most time-consuming functions are ServerAttach &
SessionBegin which shouldn't be mutexed since they have each
their own Server/Session handle.
So my question is if a single OCI Enviroment is enough for the
most demanding tasks or should I create one enviroment per
thread?
Most folks are happy with a single environment. The mutex on the
env handle is only taken when the OCI library is allocating some
memory for internal operations.

How to limit ALL data transmission except for WhatsApp in Z10?

Hello, My prepaid carrier allows me to use WhatsApp with no data limits, so I want to use data packs for WhatsApp and WhatsApp ONLY, is there a way to block ALL data transmission except for that used by Whats App?
To clarify more: my carrier debits my balance if I use voice OR data, it is not a matter of buying data packs, or limiting them, the actual limit is my balance.
The reason I am asking this is because my balance reduces little by little EVEN if I am not using WhatsApp (turned off or better said terminated from the apps manager), it is like some other applications (or even the OS) are checkin for updates or sending/receiving data in the background.
Thanks for any help you can provide me with.

Thank you for your advise,
I have done all you mentioned, but there is something missing in the options I am presented with: After checking App Manager, Device Monitor, I can't find Mobile Data Usage, I only have Battery, CPU, Memory and Storage.
'Data Usage' is available with latest OS update.
You can limit data for email accounts - Edit account - Roaming data control, Mobile data control and wifi data control - limits can be set from 5k up or to 'headers only'.
As long as you aren't syncing files, I wouldn't worry about other settings, apps will only use data when opened.

Date comparison in scripts

Hi all,
/: If &vbrk-fkdat& < '31.12.2006'.

I want to compare dates in scripts text element. how to do.
the &vbrk-fkdat& is holding 19.06.2006. and showing 'your_logo' but i need 'my_logo'.
Please find out is there any mistake in dates comparison. or let me know how compare dates
Helpful answeres are surely rewarded.

Hi all,
Thanks for your suggestions.
the solution is
/: define &dates& = '31.12.2006'.
/: SET DATE MASK = 'YYYYMMDD'.
/: If &vbrk-fkdat& < &dates&.
/: include my_logo.
/: else.
/: include your_logo.
/: endif.
/: SET DATE MASK = ''. -
> to reset date mask

Date Comparison Error

I have a database column named lastname this has text data entered in form of: 05/15/2010 and so on. ---long story on why text field and not date....
My code is as follows:
select b.lastname as sale_date, c.combined_legal as legal_address
from anthem_prod_usr.opr_logi_documents      a
,    anthem_prod_usr.opr_parties             b
,    anthem_prod_usr.opr_legal_headers       c
,    anthem_prod_usr.image_references        f
,    prod_pa.valid_dates                     g
where a.instrument_number = b.instrument_number
   and a.multi_seq = b.multi_seq
   and b.name_type = 'E'
   and b.lastname like ('__/__/____')
   and a.instrument_number = c.instrument_number
   and c.multi_seq = c.multi_seq
   and trunc(to_date(b.lastname,'mm/dd/yyyy')) between trunc(to_date('07/10/2010','mm/dd/yyyy')) and trunc(to_date('08/01/2010','mm/dd/yyyy'))
   and f.content_type_id = 'PUBLIC'
   and a.document_type = 'FORECLOSURE'
Error I receive is:
ORA-01843: not a valid month
01843. 00000 - "not a valid month"
*Cause:
*Action:
Using trunc function, I thought I was trimming time off to do only date comparison. Not sure why this error occurs.

Hi,
This shows one of the many reasons why storing date information in VARCHAR2 columns is such a bad idea.
TRUNC is irrelevant here. The error occurs in TO_DATE. You're doing TRUNC on the results of TO_DATE, so nothing you do with TRUNC will affect the error.
You must have some bad data in the column. If you can't actually clean up the table, then you have to detect the bad data before attempting TO_DATE.
Remember, the optimizer decides which conditions in the WHERE clause will be done first. There's no guarantee that
and b.lastname like ('__/__/____')
will be applied before TO_DATE. Even if it is, the condition above is just testing that the string is the right length and has slashes in the right places. It's checking that (for example) the month is between '01' and '12', or even if the month is numbers. The string '//////FOO/' meets the condition above.
See https://forums.oracle.com/message/4255051 for validating date information in SQL.
If you need help, post a complete test case that people can run to re-create the problem and test their ideas. Include CREATE TABLE and INSERT statements for any tables needed. Also post the results you want from that sample data given.
Simplify the problem as much as possible. Remove any tables or conditions or anything else that isn't related to the problem.

Oracle DB schema and data comparison tools that compare BLOBs

I'm looking for schema and data comparison tool like DBDiff or DbTools, but it has to be able to compare BLOB and CLOB fields. I went thru few products available on the market but could not find any that does that.
Can you please recommend tool that will help me with it.
Thanks,
E

Hi.
I use Comparenicus for Oracle from Orbium Software. It compares data and schema, CLOBs, BLOBs..
It can also handle large tables which is very useful for some of my environments.
Last (but not least) it has a unique feature for copying selective data from one DB to another. You can read about it this post:
Efficient way to copy business data from Production DB to Test DB
Enjoy..
