SPField.Hidden gives wrong result

This code returns fields that are hidden in the list settings page. Why is that?
var fields = from SPField field in list.Fields
where field.Type == SPFieldType.User && !field.Hidden
select field;

Yes I had the setting for 'Update all content types inheriting from this type? ' set to yes in the content type advanced settings. As I stated in the post above where I came
up with a solution: using the list.ContentTypes and then the contenttype.fields to loop through the fields the Contact field there is actually hidden. But looping through the list.Fields the Contact field is not hidden. So yes my Content Type did get pushed
down from the site content type to each of the pages libraries in each of my sub webs. But NO it does not also affect the field in list object. This can be seen both when debugging my code and also simply by using SharePoint Manager 2013.
In SP Manager if I go to Sites\mysite\allwebs\subweb\lists\pages\fields
then click the Contact item, Hidden = False
If I go to Sites\mysite\allwebs\subweb\lists\pages\ContentTypes\MyContentType\fields
then click the Contact item, Hidden = True
The solution appears to be to use the list.ContentTypes to get the field rather than list.fields. This works the way I want.

This is a bug. Got to be a bug.
This should be nothing to do with indeterminate results from ROWNUM, and nothing to do with read consistency at the point of statement start time in session2., surely.
Session 2 should never return 100101 once the lock from session 1 is released.
The SELECT FOR UPDATE should restart and 100101 should not be selected as it does not meet the criteria of the select.
A statement restart should ensure this.
A number of demos highlight this.
Firstly, recall the original observation in the original test case.

Session2>Proves nothing, Non-deterministic ROWNUM you say.
Then let's reset, recreate the index and explicity ask then for row 100101.
It should give the same result as the ROWNUM query without any doubts over the ROWNUM, etc.
If the original behaviour was correct, session 2 should also be able to get 100101:
Session1>SELECT taxid
2 FROM   taxids
3 WHERE locationid    = 111
4 AND    NVL(STATUS,0) = 0
5 AND    taxid         = 100101

--> so session 2 stops being blocked and:
Session2>SELECT taxid

4 AND    NVL(STATUS,0) = 0
5 AND    taxid         = 100101
6 FOR UPDATE;
no rows selected
Session2>Of course, this is how it should happen, surely?
Just to double check, let's reintroduce ROWNUM but force the order by to show it's not about read consistency at the start of the statement - restart should prevent it.
(reset, then)
Session1> select t.taxid
2   from

0CRM_OPPT_H (Transaction RSA3 gives wrong result)

Hi gurus,
0CRM_OPPT_H (Transaction RSA3 gives wrong result)
BBPCRM 4.0
BW 3.50 version
I had enhanced the structure "crmt_bw_oppt_h"
and also written a BADI to populate Opportunity header status.
But when I run extract checker RSA3 for CRM data,
I get wrong number of records.
I am having 95 records for Opportunities header data.
Data Records / Call = "100"
Display Extr. Calls = "10"
Above settings, I am retrieving only 61 records.
Data Records / Call = "1"
Display Extr. Calls = "200"
For the above settings in RSA3,
I am able to retrieve 95 records correctly.
The problem is that in RSA1 transaction of BW 3.50 server also,
61 records are being loaded from CRM server.
Could this be a Cache memory problem,
Are any of my BASIS settings a cause for this problem?
Any help is really appreciated and will be rewarded.
Thanks,
Aby Jacob
========

Dear Friends,
I had to do a small correction in my BADI code.
I got a solution from Online SAP HELP portal.
http://help.sap.com/saphelp_nw04/helpdata/en/eb/3e7cf4940e11d295df0000e82de14a/frameset.htm
Notes on BADI Usage
====================
The instance generated through the factory method should be declared
as globally as possible or generally be passed as a parameter
to ensure that the initialization process must be run as rarely as possible
just once would be best. In no case should you discard the instance as soon as
it is generated or repeatedly run the initialization process in a loop.
Within the adapter class interface,
required database accesses are buffered locally,
so that each access is executed once only.
However, repeated initialization makes
the buffer useless and dramatically reduces performance.
Due to the local buffering, you can call Business-Add-In methods
without having to expect considerable performance restrictions,
even if no active implementations exist.
Also, if the definition of the Business-Add-In is filter-dependent,
a single instance is sufficient.
However, you should not do without initialization altogether.
Even if you could call static methods of the implementing
class of the Business-Add-In implementation without an instance,
you would lose the benefit of performance improvement through
the Business-Add-Ins and the possibility of multiple use.
If you switch the method type in the interface from the static method
to the instance method at any time in the future,
many code adjustments are required.
In addition, you can no longer use default code that is provided.
Many Thanks to ROBIN

Bug in 10.2.0.3.0 - sum gives wrong result?

Hi,
I've found a strange behavior when using sum without group by. Firs I thought it's hash group by, but it's supposed to be fixed in 10.2.0.3, and setting GBYHASH_AGGREGATION_ENABLED=FALSE also didn't fix the error.
We have automated tests to verify our results of views and procedures. The test works on a small subset of data, so it uses the following (pseudo) select to calcuate the expected value:
select
sum(round(trw.a* rc.b,2))
into
tmp_result
from
trw
inner join rc on rc.cp_id= trw.cp_id and rc.r_id= trw.r_id and rc.pc_id=param_pc_id
where
trw.t_id= test_t_id;
Now, this select returns a value that's a little bit different than a value we get from the view we are testing.
The view is basically the same, it has a group by trw.t_id and some simple logic.
The interesting part is this:
if I dump "un-summarized" data from the view and the select statement into temporary tables, i get the same rows, and sum over those rows gives the right value.
Either I've missed something obvious or it truly is a bug. Any ideas?
Regards
Jernej

OMG, my bad, I'm sorry.
That's what happens when you test sysdate dependent results.
Sorry again

Count function on months column gives wrong result

Hi,
I am on OBIEE 11.1.1.7.150120.
I used the count function on the month column and rather than getting 12 as the answer i get 365. (i used a filter on the year column to restrict it to one year)
How could this happen?
Any help would be appreciated.

I was able to get the answer as 12 on the month column in the Dim_Time using the count distinct.
The main reason i was trying this is because i have a VALUE column in VIew_A. I am trying to sum the values of these, but when i use the sum function, the output is quite huge and wrong. I dosen't match with the monthly figures.
For eg:
Month
Income Cost

186.96

1,638.38
DEC
215.81
857.30
869.31
24005.34
But if i use the sum function on the Income/cost column, the value i get is
C_MONTH
SUM(INCOME_COST)
JAN
5,795.86
FEB
8,660.21

This just doesn't work out. I need the answer to be 24005 by using the sum function

GetFloatProperty gives wrong result for values out of range

Hi
When the method setFloatProperty is called by setting the float values out of the range,then calling getFloatProperty does not give NumberFormatException.
Float value set more the MAX_VALUE of float returns infinity when getFloatProperty is called.Similar problem occurs with setDoubleProperty.This behavior is confusing.can anyone help me out.
Regards
saroj13

Throwing a NumberFormatException would never make sense in this situation. The exception indicates that you are trying to convert a String to a number, but the String does not contain a valid number. eg. "as3"; when a conversion was attemted would throw a NumberFormatException.
Floats and Doubles in Java comply with the IEEE 754 standard which mandates the behaviour of the types.
Could you explain why you find this confusing?
Hope this helps.

Week function gives wrong result for last week in year

Week(CreateDate(2011,12,25)) returns 51 - correct
Week(CreateDate(2011,12,26)) returns 53 - wrong
It looks like all last weeks of the year are 53 whereas the next year with 53 weeks should be 2015.
See http://tuxgraphics.org/toolbox/calendar.html for example.
I am running CF9 on Windows 7 with Java V6 update 29.
This is causing me a problem. Any ideas for a workaround?
Doug

Here is my general solution for my cfc which seems to work for all dates up to 2100 at least.
Hope it can help if you need a Week function to replace the CF one.
<cffunction name="getISOWeekNum" access="public" returntype="Numeric" hint="Gets ISO week number in which date occurs.">
 <cfargument name="date" type="date" required="true" hint="Date for which you wish to know the week number">
 <cfset var weeknum = 0>

Bug: "=" does give wrong result!

hi, this is the most frightening oracle bug I saw. 10gr2, data imported from an 9 export:
select count(*) from T where F = 1;
0select count(*) from T where F between 1 and ;
1165select count(*) from T where nvl(F, 1) = 1;
1165select count(*) from T where F <= 1;
1165select count(*) from T where F < 1;
0in one word: HELP !
ps: no index on F, stats computed...

it is a bug actually, because an execution plan should not affect the result of the query ! Report it to metalink if you do have a valid support contract

Search string-1 in string-2 gives wrong results.

Hi,
I am searching for the string 'COM' in the sentence
below.
I am getting the string positons of string "COM"
as 1 and 16.
It Should be 1 and 19.
thanks
sharath
SET SERVEROUTPUT ON
DECLARE
str VARCHAR2(200):='COM-1 Hello world COM-1 speaking';
pos NUMBER ;
ps NUMBER :=0 ;
srch VARCHAR2(20) :='COM' ;
BEGIN
While( ps <= length(str))
Loop
pos := instr(str,srch);
If pos > 0 then -- found string COM
str := substr(str,pos + length(srch));
dbms_output.put_line('COM found in pos ==> ' || pos );
End If;
ps := ps + 1;
END LOOP;
END;

I believe the problem is that you are redefining the variable str within your loop. Once you find the first occurrence of "COM" in the string, you modify the string to remove that occurrence and then search again. The logic of your stored procedure is
Loop 1:
str = "COM-1 Hello world COM-1 speaking"
- first occurrence of COM is at position 1
Loop 2:
str = "-1 Hello world COM-1 speaking"
- first occurrence of COM is at position 16 in this new string
Since you are removing the first three characters of the string when you call substr at the beginning of the second loop, you're looking for the position of "COM" in a slightly different string the second time around, hence the confusion.
If you want to find the position in the original string, you'd want something like
CREATE OR REPLACE PROCEDURE findOccurrence( string IN varchar2, search IN varchar2, offset IN number)
AS
currentPosition NUMBER;
BEGIN
currentPosition := INSTR( string, search );
IF( currentPosition > 0 )
THEN
 dbms_output.put_line( 'Search string found at position ==> ' || to_char(currentPosition+offset));
 findOccurrence( substr( string, currentPosition+length(search) ),
 search,
 currentPosition+length(search)+offset-1 );
END IF;
END;
scott@jcave > exec findOccurrence( 'COM COM COM', 'COM', 0 );
Search string found at position ==> 1
Search string found at position ==> 5
Search string found at position ==> 9

SQL Server 2012 Time(7) DataType values Comparison giving wrong result. Please help

We have a Table with StartTime and EndTime columns in Time(7) datatype, so we want to count the rows for each hour from 6 AM to 5 AM. If a record in table is as StartTime= 7 PM to EndTime = 5 AM (a shift of an employee) then the result is wrong beacause
being time(7) datatype the EndTime(5AM)< StartTime(7PM) in 24 hours format so following query gives wrong results.
select
* from EmpSchedule
where (StartTime>='19:00:00.0000000'
OR EndTime>='19:00:00.0000000')
Please help me out. Thanks

Enterprise Manager does not give correct results

I am using version 9.0.2.0.1 core edition(oc4j & web-cache).
My application consists of business components, java beans and jsp. It is running fine.
Oracle enterprise manager is not giving correct results of memory/cpu usage by oc4j_home and bc4j.
Some times it does not gives result, when i refresh it twice or thrice it shows results.
But results are not correct. On each refresh it gives different results.
Then it is very hard to find which resuslt is correct.
waiting for response,
Tahir.

i have been using 9iAS versions 102*, 90200, 90201, and now using 903.
As stated above, some times the results for oc4j_home is displayed.
But the memory/cpu usage for bc4j is never shown.
Also, its radio-button is always disabled. while its status is "running".
On BC4J page, it also shows results of application modules created. But these results are usually wrong.
How bc4j will be enabled, and how its memory results can be get ???
Tahir.

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
Select "system.log" from the file list. Enter "backupd" (without the quotes) in the String Matching text field. Post the messages from the last backup, beginning with "Starting standard backup."
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Do not post many repetitions of the same message.

Maps can not find my location, or gives incorrect results

when I tap the "locator" icon at the bottom right of Maps, it can't find my location, or gives incorrect results such as San Francisco, or somewhere south of Detroit, MI

This is what I did, and it worked for me. My location was coming up in the correct city, Philadelphia, but at the wrong neighborhood, a couple of miles away. I turned off the wifi, and made the locator find me by Edge only. Then I turned the Wifi back on and had the locator find me again, and it went back to the wrong location, but 2 seconds later found the correct address within a few blocks. I have the Original iPhone BTW.
