Invalid Floating Point operation when used with group by

Posted By:      Posted Date: September 30, 2010    Points: 0   Category :Sql Server


This is related to a question I asked in the forum before and it looks like it is not handling the negative numbers within the log expression. Please let me know.



declare @insurance table


groupid int,

classid varchar(20),

creditamt varchar(20),

debitamt varchar(20),

insuraceflag varchar(30)




 ;with cte as


select groupid,classid,creditamt,debitamt,ROW_NUMBER() over (partition by GroupId order by ClassId ) as rn from @insurance


 cte1 as


select t.GroupId,t.debitamt,t1.Amt from 

(select * from cte where rn = 1)t

inner join (select GroupId,exp(SUM(LOG(CAST(isnull(creditamt,debitamt) as decimal(8,4))) )) as Amt from cte where rn <> 1 group by GroupID)t1 on t.GroupID = t1.GroupID


 select * from cte1 -- this bombs when the inside log expression is NEGATIVE or ZERO.

Why is ParseXPathExpression throwing a Floating-point invalid operation? (re: WinDbg)


I'm a software developer working for the federal government and we use a third party product that we are suddenly having problems with.  The product worked perfect on Friday but after the weekend it no longer works.  (ie. the application/process starts but nothing appears on screen and it appears to hang, etc)

I've never really used WinDbg but I'm trying to learn but looks like MS.Internal.Xml.XPath.XPathParser.ParseXPathExpresion is throwing a Floating-point invalid operation exception.  (0xc0000090)

I've stepped through the code (with WinDbg) and here is the managed stack trace when the exception is first thrown:

User group invalid for new document



Defined a user group and a site column of type people/group directing to this group.

Also defined a content type and added the site column to this content type.

When I create a new word document of this content type, word opens displaying my site column ok. But when I enter it, I see that all active directory (AD) entries are displayed. I want it to display only those users I added to the user group I created. Moreover, users can select any user from AD, which makes defining a user group and a site column meaningless.

This problem is only in creating new documents with Word. If I edit properties of an already existing document in my site, everything is ok: I can select only the users in the group.

processing measure group : memory error : the operation cannot be completed because the memory quota

Hi, I'm stucked with this problem. Untill last week, the cube processed without any problem. Since last week, I'm getting this error. I have been searching in different forums, and I tried some suggestions, like changing memory limit properties, ... It is getting worse.. So I reset all properties to default again. I am running SQL-Server + MS-AS 2005 SP2 on server with 4GB of memory. This is a dedicated server, nothing else is running on it. The fact table has +/- 14 million records, several dimensions en 2 measure groups. I don't have problems to process the dimensions, but when I try to process the cube or the measure groups of that cube separately , the error persists. I have changed the datasource view, and replaced the fact table by a Named query. Even when I put a 'WHERE datapart( year , fact_date ) >= 2009 ' clause to reduce the number of records to +/- 5 million, I'm still getting the error. I don't understand what is wrong, the cube always processed since +/- 2 years. As I said, I have found a lot of this kind of Issues on different websites, I have been trying to change some properties. But this still does not solve the problem. Could it be that MS-AS settings are corrupt somewhere ? Is it a good idea to re-install MS-AS 2005 + SP1 + SP2 ? Or is there another reason possible ? I really appreciate any kind of help, because I'm

String.Format rounding down floating point number


Hi, I'm having an issue with String.Format, can somebody tell me if it's something I'm doing.


I'm using C# 2.0 I have code which looks a little bit like this:


Code Snippet

string result;

float floatToConvert = 10780503.000000f;


result = String.Format("{0:0,0}",floatToConvert);



Now I would expect result to have a value of "10,780,503" after this line of code, but it doesn't it has a value of "10,780,500"...


If however I do this:


Code Snippet

string result;

float floatToConvert = 10780503.000000f;

Quad-precision floating point in .NET?

When does Microsoft plan to add quad-precision floating support to its .NET CTS data types (such as IEEE 754 binary128)? I.e. when is it going to become available to .NET C#, C++, etc.? I have published a WP7 calculator app, and I am currently working on an enhanced scientific mode in landscape display. Currently, the only available floating point is float and double; hence, I have a maximum of 15 digits precision available using double.

While double precision (theoretically) is all anyone ever needs, in a competitive sense, that's not true. Microsoft supports 32 significant digits in the scientific mode of its Windows calculator, presumably because it's written using the unmanaged C++ quad-precision library. More importantly, other competitive platforms support more than double precision.  Rgardless of any theoretical arguments about how someone may never need to use more than double precision, if quad precision is supported elsewhere, for practical, competitive-product reasons .NET should support it too for WP7 apps.

The Decimal structure is not adequate for many reasons:

- Decimal was intended only for financial calculations where a loss of precision during rounding operations is unacceptable.
- Decimal is much (much) slower than double for most operations, primarily because double operations are done in binary,

Problem to group radio button across gridview rows

In general no one can easily group or make a single selection from radio button list inside gridview rows. There are a lot of way to make a single or unique selection from list.

Thats why i tried to group the radio buttons in vertical manner. Let i have a requirement like below:

How do I get the emails of all the members of a given group in ActiveDirectory - Need help



  I have a need to send out emails to all the people who are in a given group say "HR Department". I need to be able to get all the emails through a for loop and then as it retrieves I should send emails to them. Can some one please help me with the code

this is what I came up with but not sure how to go about writing a for loop to get all the emails in the given group.

public static string SendEmails(string loginName)
        string Department = "HR Department"
        string userName = ExtractUserName(loginName);
        DirectorySearcher search = new DirectorySearcher();
        search.Filter = String.Format("(SAMAccountName={0})", userName);
        //search.Filter = String.Format("(SAMAccountName={FAY ImprovmentForm})", userName);
        //LdapSearcher.Filter = string.Format("(&(objectClass=user)(department={0}))", Department); 
        //search.Filter = string.Format("(&(objectClass=group)(SAMAccountName=" + Department + "))", userName);

A lengthy operation in an ASP.NET web service


I've built an ASP.NET web service with .NET 2.0 (an asmx file). I invoke a web service method using Ajax. The method takes a substantial amount of time to execute (5 minutes to 1 hour). I believe it's not a good idea to "hang" the web request for so long.
I'm wondering if the web service method could spawn an additional process which in turn would execute the lengthy operation and notify the web service once the operation is completed.
Are there any good practices regarding this kind of functionality?
