I'm trying to perform a calculation on a field in SQL Server that
should return a value with a decimal point. My problem is that the
value returned is truncated without the decimal point. Is there a
setting that needs to be turned on in SQL server to allow this?
I need to write a floating point value to a column in a SQL server database. I have the following line ofcode, that formats the float value before passing it off to the stored procedure. Please look at the line of code below. Does the 8 after SqlDbType.Foat mean that this will be a floatingpoint with 8 signigicant digits past the decimal point? mySqlCommand.Parameters.Add("@Price", SqlDbType.Float, 8).Value = float.Parse(InitialPrice);
I can't see any reason for this error, not having a high level understanding of maths I thought I'd post it and hope someone could share some light on it.
I yesterday got called by a client who said that a payment for £15 + VAT was being passed to their payment gateway as 17.62 when it should be 17.63. The VAT calculation is performed in a SQL Server 2000 stored procedure. In the end I tracked it down and it wasn't a propblem with my calculation.
The price was coming out as 17.63 fine. The stored procedure then had to return this price in pence (17.63 * 100 = 17.63). When I put in a print statement with this calculation it was correct but when I output the variable that the result was assigned to it was coming out as 1762.
The variable that the result was being put into was of real datatype.
I then wrote a udf to test this. Here is the function:
CREATE FUNCTION dbo.POUNDS_TO_PENCE ( @POUNDVALUE real ) RETURNS INTEGER AS BEGIN
RETURN @POUNDVALUE * 100
END
As you can see nothing very special.
If you run this runction and pass in 17.63 it will return 1762!!!
The bit I don't get is if I change the @POUNDSVALUE intput variable to type float it returns the correct amount.
I've also found that the same problem occurs when passing in £30 + VAT (35.25) + 1pence. So, 35.26 comes out as 3525 instead of 3526. This is the case if you keep doubling the number (and adding a few pence here and there).
Does anyone know why this is or is it a bug in the processor?
The SQL books online say the following about the float and real data types:
-------------------------------------------------------- float and real (T-SQL) Approximate number data types for use with floating point numeric data. Floating point data is approximate; not all values in the data type range can be precisely represented.
Syntax float[(n)] Is a floating point number data from - 1.79E + 308 through 1.79E + 308. n is the number of bits used to store the mantissa of the float number in scientific notation and thus dictates the precision and storage size. n must be a value from 1 through 53.
n is Precision Storage size 1-24 7 digits 4 bytes 25-53 15 digits 8 bytes
The Microsoft® SQL Server™ float[(n)] data type conforms to the SQL-92 standard for all values of n from 1 to 53. The synonym for double precision is float(53).
real Floating point number data from –3.40E + 38 through 3.40E + 38. Storage size is 4 bytes. In SQL Server, the synonym for real is float(24).
Intermittently, the following error has been displayed when a SQL job on our box (SQL Server 2000 Service Pack 4 running on Windows 2000) runs.
'A floating point exception occurred in the user process. Current transaction is canceled.' The error number given is 3628 though I've also seen a 4xxx number (not at machine at the moment so cant be precise for the latter).
The intermittent problem over the last two days has become more regular and now does not appear to be related solely to the SQL job. For example, when connecting to the box using my local copy of SQL 2005 Management Studio and I attempt to browse the database objects I get this problem.
To the best of my knowledge, this server has not had any software installed on it and/or nothing has changed on it recently.
It has now got to the point that this particular job no longer runs. The job in question, in case this is significant, is a vanilla stored proc that returns data using OPEN ROWSET to communicate with an Access database (this connectivity has been verified to be okay, in that other similar jobs all run just fine)
If anybody can shed some light and/or point me in the right direction I would be extremely grateful.
Hi,I would like to know, if I need to do some floting point operations(mainly multiplication and division) on each roll of a table, should Iread the data out from the DB and do the calculation with a programminglanguage, say C#, or should I just use sql to do it on the sql server.An obvious advantage of doing it in the sql server is that you dontneed to transfer the data between the sql server and he applicationserver.But I am not sure if there are any other factors that will overridethis advantage: like the performance of doing lots of floting pointoperations in sql server.How is the performance of doing floting point operations in sql servercomparing to C# or other languages?Also are there any other factors that should be considered for thiscase andare there any other advantages to do this is sql server or in c#?ThanksBenny*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
Hi SQL people, I have rating system on pages in my website, each page being rated one to five by users. At the back end, an ASP.NET page displays the average rating and number of ratings for each page. As the rating is stored as an integer, the SQL statement returns an integer average. I would like to get a floating point average. Currently the statement used to return the average looks like this:
select AVG(Rating) as AverageRating from Ratings where [RatingPage] = @RatingPage
Is there a simple way to modify this to return a floating point average without iterating through the records, or converting the Rating field to a float?
I got below error in the SQL Server Production Server and i checked in the microsoft site it needs to install SQL Server service pack 4 to resolve the problem.
"A floating point exception occurred in the user process. Current transaction is canceled"
I need help that i want to reproduce this below problem in the SQL Server environment and tried several ways but no luck.
System.Data.SqlClient.SqlException: A floating point exception occurred in the user process. Current transaction is canceled. at System.Data.Common.DbDataAdapter.Update(DataRow[] dataRows, DataTableMapping tableMapping) at ...etc etc
when updating one particular table, but not when updating another using nearly the same code.
I've searched and searched on the inet, but with no joy.
Microsoft have several different manifestations of it, under various different circumstances, but the solutions all seem to involve installing SP4, which by the looks of it is a massive procedure that you have to go to university to be competent to do.
In any case, according to Enterprise Manager, I already have SP4 included. On the other hand, the one file of mine I checked the date of against MS's hotfix file list was 2002 not 2003, so who knows?
My Service Manager is v 8.00.760, and it's the Development Edition (ie it's all running on the one machine).
According to the info on sqlDataAdaptor.update, the sqlError that gets returned as part of the sqlException contains fields Class, which gives the seriousness of the error, and State, which identifies the exact error. I get Class=16 (user-fixable) and State=1, which we have to go to SQL Books Online to discover the meaning of. SQL BO probably sounded like a good idea to W.Gates, but it took me half an hour to get anywhere near finding out what that '1' meant. When I did, it was (guess): 'A floating point exception occurred in the user process. Current transaction is canceled.' !!!
Can anyone please tell me what exactly might be causing the error?
I am trying to understand why SQL Server gives me significantly lower precision than many of the other sources that have tried when using the POWER function. My environment is 2008 R2 SP2 (10.50.4000.0 X64, Standard edition) on Windows 2008 X64 SP1

I have created calcalated measures in a SQL Server 2012 SSAS multi dimensional model by creating empty measures in the cube and use scope statements to fill the calculation.
(so I can use measure security on calculations
as explained here  )
SCOPE [Measures].[C];
THIS = IIF([B]=0,0,[Measures].[A]/[Measures].[B]);
First off, I appreciate the time that those of you reading and responding to this request are offering. My quesiton is a theoretical and hopefully simple one, and yet I have been unable to find an answer to it on other searches or sources.
Here's the situation. I am working with SQL Server 2005 on a Windows Server 2003 machine. I have a series of databases, all of which are in Full recovery mode, using a backup device for the full database backups and a separate device for the log backups. The full backups are run every four days during non-business hours. The log backups are run every half hour.
Last week, one of my coworkers found that some rarely-used data was unavailable, and wanted to restore a database to a point in time where the data was available. He told me that point in time was some time back in November.
To accomplish this, I restored the database (in a separate database, as to not overwrite my production database) using the Point in Time Recovery option. I selected November from the "To a point in time" window (I should note that this window is always grey, never white like most active windows, it seems), and the full database backup and the subsequent logs all became available in the "Select the backup sets to restore" window.
I then tried a bevy of different options from the "Options" screen. However, every restore succeeds (ie: it doesn't error out), but seems to be bringing the database back to a current point in time. It's never actually going back to the point in time I specify.
My questions are as follows:
a) Is it possible to do a point in time recovery to a point in time BEFORE the last full database backup?
b) If so, what options would you recommend I use? (ie: "Overwrite the existing database", restore with recovery, etc etc).
I again appreciate any and all advice I receive, and I look forward to hearing from anyone and everyone on this topic. Thank you.
I'm running SQL Server 2005 on a Server 2003 machine serving both our home network as well as a remote site through a point-to-point T1. While file transfer speeds are up to par, the remote site's interaction with SQL Server (Point of sale system) is very slow. After testing I am certain that it has nothing to do with the actual physical machine in place neither is it an issue with the program itself since speeds are as they are supposed to be over the home network lan. It seems that there might be a packet size issue or something of the sort. Has anyone dealt with this before or have any thoughts?
My predicament is - where do I do these calculations - in my vb.net code or in an SQL stored procedure?
My manager has handed me a task of converting an excel file she uses in to a web aplication.
While it has been easy to devise what should be the screens and how to capture data, I am struggling over how to code the calculations.
The calculations in excel are pretty simple. These are just sequential calculations (about a 150 calculation for average 500 rows). Mathametical operations include sum, average, max min - regular excel stuff. Some calculations involve vlookup (equvalent to calculation based on value derived from a reference table).
So I am stil wondering - where do I do these calculations - in my vb.net code or in an SQL stored procedure?
Since these calculations are required a produce a result in an online environment, what will be faster?
I tried to do a proof of concept by creating a sample calculation in a .NET class and an in a stored procedure. The choice is still not clear. SQL code execution time was not bad. But SQL code tended to be very messy.VB.net code seemed to be a little slow. But seemed a more organised to look at.
Any views that you can offer will be very helpful.
I need to calculate the overall GPA for a student in a particular class.
YEAR SCHOOL STUDENT IDENT GRADE TEACHER CLASS GPA 2007 Snow Canyon High Student1 321649 10 Teacher1 Earth Systems 0.0000 2007 Snow Canyon High Student1 321649 10 Teacher1 Earth Systems 1.6700 2007 Snow Canyon High Student1 321649 10 Teacher1 Earth Systems 3.3300 2007 Snow Canyon High Student1 321649 10 Teacher1 Earth Systems 3.6700 2007 Snow Canyon High Student1 321649 10 Teacher2 Elementary Algebra 0.0000 2007 Snow Canyon High Student1 321649 10 Teacher2 Elementary Algebra 0.6700 2007 Snow Canyon High Student1 321649 10 Teacher2 Elementary Algebra 1.0000
The problem I'm having is that a student may not taken the class for four terms (as in the Elementary Algebra example above). So I can't hard code it to sum the gpa and divide by 4; it needs to be the number of terms the student took the class.
Here's my sql:
select trnscrpt.schyear as [Year], school.schname as School, rtrim(stugrp_active.lastname) + ', ' + rtrim(stugrp_active.firstname) as Student, trnscrpt.suniq as suniq, stugrp_active.graden as Grade, trnscrpt.teachname as Teacher, trnscrpt.descript as Class, gpamarks.gpavallvl0 AS GPA
from dbo.trnscrpt inner join dbo.stugrp_active on trnscrpt.suniq = stugrp_active.suniq INNER JOIN school ON stugrp_active.schoolc = school.schoolc INNER JOIN gpamarks ON trnscrpt.marksetc1 = gpamarks.marksetc AND trnscrpt.markawd1 = gpamarks.mark
where trnscrpt.graden >= 6 and trnscrpt.markawd1 not in ('NC','NG','P','W','WA','WF','WI','WP') and trnscrpt.subjectc in ('LA', 'MA', 'CP', 'CB') and trnscrpt.schyear = 2007 and stugrp_active.schoolc = 725
In period = 2, status code change from InStock to OutOfStock: Product 1 (Count=1) In period = 1, number of products with status code = InStock: product 1 and product 2 (Count=2)

I would like to have the result as follows: sector RefDate price priceChangeSinceYesterday priceChangeSinceLastWeek priceChangeSinceLastMonth pharm 9 oct 2007 100.99 100.99-96.34 100.99-98.34 100.99-lastmonth's price value
select sector, RefDate, price, priceChangeSinceYesterday??, priceChangeSinceLastWeek???, priceChangeSinceLastMonth?? from table1
My aim is to do something like what I have explained below and I was planning on building this logic at the Database level only rather than on the frontend code.
There are certain allocations(transactions) that happen on a periodic basis and I am storing these transactions in the PurchaseTranMaster and PurchaseTranDetail table. These transactions are categorized as 'Main' type and the amount could be allocated for one or many categories in a single transaction. Below is how it will be saved in the 2 table
PurchaseTranMaster
TranID TranDate TranType 1 14-March-2008 Main 2 17-March-2008 Main 3 1 9-March-2008 Main
PurchaseTranDetail
TranID Amount Category Debit_TranId 1 1000 A 1 1000 B 2 2000 B 3 300 A 3 400 C
Now what happens is users of my application can make purchases under all these categories only until the Balance under these categories is > than purchase amount. The Balance is calculated as sum of all transactions. It means that w.r.t the above data the balances for each category is(this is not stored in the database)
A 1300 B 3000 C 400
So lets say a user does make a purchase(Trantype is 'SUB') of 300 under A and 400 under B in a single transaction. The data would then be stored in the tables as
PurchaseTranMaster
TranID TranDate TranType 1 14-March-2008 Main 2 17-March-2008 Main 3 19-March-2008 Main 4 20-March-2008 SUB
PurchaseTranDetail
TranID Amount Category Debit_TranId 1 1000 A 1 1000 B 2 2000 B 3 300 A 3 400 C 4 300 A 1 4 400 B 1
In the PurchaseTranDetail the Debit_TranId value means that the amount has been marked against the TranID 1. This TranId is not handpicked by the user and the system should allocate it accordingly based on the amount available for a particualar category for a Main Transaction. It means that before TranId 4 was saved in the database then the system would first check whether the Total available balance for A >=300 and B>=400 (in our example above it is 1300 and 3000 resp) Then if the Balance is > than the puchase amount then the allocation would be done by the system and this would be done against the TranID whose TranDate was the earliest, so thats why the Debit_TranId column has 1 as TranId 1 was the earliest.so logically now the balance for the categories would be (this is not saved in the database)
A 1000 B 2600 C 400
So next time again when a user would make a purchase(transaction) under A for 800 and under B for 1000 then if the balance is greater than the purchase amount(which in this case it is) the allocation would happen according to the earliest TranId and this time amount would be partly marked against TranId 1 , TranID 2 and TranID 3. The data would look like this
PurchaseTranMaster
TranID TranDate TranType 1 14-March-2008 Main 2 17-March-2008 Main 3 19-March-2008 Main 4 20-March-2008 SUB 5 21-March-2008 SUB
TranID Amount Category Debit_TranId 1 1000 A 1 1000 B 2 2000 B 3 300 A 3 400 C 4 300 A 1 4 400 B 1 5 700 A 1 5 100 A 3 5 600 B 1 5 400 B 2
I need to do the above taking into consideration that there could be multiple users making purchases(concurrency). Also I was building my logic on doing the above whether to use cursors or loops. I just need to know how do I write my stored procedure and what would be the most efficeint way of doing the above.
The design for creating the above sample tables is below
insert into PurchaseTranMaster values(convert(datetime,' 14-March-2008',103),'Main') insert into PurchaseTranMaster values(convert(datetime,' 17-March-2008',103),'Main') insert into PurchaseTranMaster values(convert(datetime,' 19-March-2008',103),'Main') insert into PurchaseTranMaster values(convert(datetime,' 20-March-2008',103),'SUB') insert into PurchaseTranMaster values(convert(datetime,' 21-March-2008',103),'SUB')
insert into PurchaseTranDetail values(1,1000,'A',0) insert into PurchaseTranDetail values(1,1000,'B',0) insert into PurchaseTranDetail values(2,2000,'B',0) insert into PurchaseTranDetail values(3,300,'A',0) insert into PurchaseTranDetail values(3,400,'C',0) insert into PurchaseTranDetail values(4,300,'A',1) insert into PurchaseTranDetail values(4,400,'B',1) insert into PurchaseTranDetail values(5,700,'A',1) insert into PurchaseTranDetail values(5,100,'A',3) insert into PurchaseTranDetail values(5,600,'B',1) insert into PurchaseTranDetail values(5,400,'B',2)*/
I´m working on SSRS 2005 trying to calculate YTD for the total sale. This is what I got so far:
Code Snippet
WITH MEMBER [Measures].[YTD Amount] AS 'SUM(PeriodsToDate([DATE].[Year]),[Amount])' SELECT {[Measures].[Amount],[Measures].[YTD Amount]} ON COLUMNS, [DATE].[Month].Members ON ROWS FROM [SKY] My Date hierarcy is: Year Month
When running this query all I get is very small number for Amount column, almost zero for all months and the YTD Amount Column is only showing (null).
Hello Friends I have 3 tables 1) Product Id, ShortName 2) IncomingStockId, ProductId, Quantity, InDate 3) OutGoingStock Id, OutDate, ProductId, Quantity I need to get the results like thisProduct name, quantity in stock today the "quantity in stock today" = sum (quantity recieved) -sum (quantity sent) Thank you for your timeSara
Hi. i have the code : cmd = New SqlCommand("SELECT sales,country,year FROM salesTable WHERE (country = " & (CountryBlk) & " AND branch = " & (NameSnif) & " AND datepart(yyyy,year)=" & (YearBlk) & ") order by datepart(mm,year) ", cnn) cnn.Open() rdr = cmd.ExecuteReader( _ CommandBehavior.CloseConnection) While x < 12 If rdr.Read = Nothing Then Exit While End If varcount(x) = rdr("sales") TempMonth = rdr("year") MonthNumber(x)=datepart(DateInterval.Month,TempMonth) x = x + 1 End While
i want to calculate and put into the varcount(x) value all sales of the same month
I need to create a user defined function to calculation the difference between today and a future date. The result needs to be in days, hours, and minutes formatted as per the following example: 1d / 4h / 30m. I have a moderate level of SQL exprience. however, I would appreciate some expert advice as the best way to approach this.
hello everyone, I have a problem of calculating a date, for example, how do i find out the begining date of the week and ending date of the week for certain date, and how do i find out the beginning date of the month and end date of the month for a certain date, thanks
Hi All! I need a query to find all dates from today to one-year back. If I start from today day I need find all dates until 11/12/98. Thanks a lot. Greg.
