Decimal Scale Overflow
Jun 27, 2001
This is not a real big deal, cause I worked around it.. but I just tried to INCREASE the scale on a decimal column & got an arithmatic overflow error. I can understand why this would occur if trying to decrease the scale, but not increasing it. This is not a computed column.. why does SQL give an overflow error if all it has to do is add a couple of zeros to the end? Yes, I know SQL considers them to be different data types, but this is still confusing me.

I am using the statement below to calculate the average scores of the columns. When the result set is returned I would like to have a scale of 2. I am currently returning a scale of 6. What could I do to fix this?
Thanks for you help,
John
SELECT ((CONVERT(decimal(4,2),c2_3) + CONVERT(decimal(4,2),c2_15) +
CONVERT(decimal(4,2),c2_16) + CONVERT(decimal(4,2),c2_17)) / 4 * 100) AS Score_A

I am working with an off the shelf app that controls decimal places through the application. All columns underlying the apps 'numeric' fields are floats. We are writing some scripts that need to compare numbers and some of them look like the second row
KELLYJ 2.1233
DONOVM 1.6000000000000001
OLSSON 15.3750
I have tried using round and cast. My examples work like the following:
SELECT 27.719999999
SELECT CAST(ROUND(27.719999999,4) AS DECIMAL(50,4))
When I try the same against a column to update the entire table it leaves the rows like above as longer to the right of the decimal point.
Any pointers on how to get these numbers back to 4 decimals places would be much appreciated

Hi,
I have a derived column transformation which adds a new column of type Decimal with scale 2.
The expression is (6800 / 464)
Runs fine but it returns
14.65
While if I run any of the following queries in query analyzer SELECT 6800 /
464OR
SELECT CONVERT(DECIMAL(10,2), 6800 / 464)
They give me 14.66.
My question is, why both the tool of same product differs in the way they work ? and How could I have SSIS to work like TSQL ? I tried typecasting in derived column expression and ROUND function too. But still, the output is same.
Any help in this will sincerely be appreciated.
Thanks

On table TABLENAME, I have increased the size of column C to decimal(38, 14); maximum size and an excessive amount of precision.
If I do a
SELECT MAX(CONVERT(DECIMAL(7,2), A) / B) FROM TABLENAME
SELECT MIN(CONVERT(DECIMAL(7,2), A) / B) FROM TABLENAME
I get 3.0000000000000 for the MAX and 0.1000000000000 for the MIN value, yet if I update
UPDATE TABLENAME SET C = CONVERT(DECIMAL(7,2), A) / B WHERE B <> 0
Msg 8115, Level 16, State 8, Line 1
Arithmetic overflow error converting numeric to data type numeric.
The statement has been terminated.
Obviously I have obscured the column names and table name, but I am puzzled as to why values in the range 0.1 to 3.0 should give an overflow error.
I am using SQL2005 SP2

I've a SQL view performing a number of very precise calculations ie.495/(1.112 - (.00043499*((Col1 + Col2 + Col3))) + ( .00000055 * ((Col1+ Col2 + Col3)) * ((Col1 + Col2 + Col3))) - (.00028826 * Col4))) -450)/100Obviously this sometimes causes a precision issues because the floatand real datatypes don't hold precise values... My problem is thatconverting to the numeric or decimal datatype easily produces an errorif the precision is not big enough to hold the resulting output... Sohere's my questions:Does anyone see a problem with me maxing out the precision of thedecimal datatype (ie. use DECIMAL(38,8) across a couple dozeninter-related formulas?So the above code would now exec like this:495/(CONVERT(DECIMAL(38,8),1.112) -(CONVERT(DECIMAL(38,8),.00043499)*((Col1 + Col2 + Col3))) +(CONVERT(DECIMAL(38,8),.00000055) * ((Col1 + Col2 + Col3)) * ((Col1 +Col2 + Col3))) - (CONVERT(DECIMAL(38,8),.00028826) * Col4))) - 450)/100If anyone does see a problem with this approach, could you suggestanother alternative?

I am trying to setup an indicator value for an SSRS report to show green and red values on a report, based on the NRESULT value. The problem I am facing is that I have several different CASE statements that have the same logic, and they are processing just fine. NRESULT is a decimal field, so no conversion should be necessary. I do not know why I am getting the "Arithmetic overflow error converting varchar to data type numeric." error message.
Below is the CASE statement where the error is occurring. It is in the part of the ELSE CASE. The first CASE works just fine when the ELSE CASE is commented out. If I also change the ELSE CASE statement to say "else case when LEFT(NRESULT,1) = '-' then '0'", then it processes fine, too, so it has to be something I am missing something in the check on negative values. I do need the two checks, one for positive and one for negative values, to take place.
case when LEFT(NRESULT,1) <> '-' then --This portion, for checking positive values, of the CASE statement works fine.
CASE WHEN LEFT(ROUND(NRESULT,2),4) between 0.00 and 0.49 THEN '2' --Green
ELSE CASE WHEN LEFT(ROUND(NRESULT,2),4) > 0.49 THEN '0' --Red
ELSE '3' --White
END
END
else case when LEFT(NRESULT,1) = '-' then --This portion, for checking negative values, of the CASE statement is producing the conversion error message.
[code]....
I checked the NRESULT field, and there are not any NULL values in there, either.

I am working with a legacy SQL server database from SQL Server 2000. I noticed that in some places that they use decimal data types, that I would normally think they should be using integer data types. Why is this does anyone know?
Example: AutomobileTypeId (PK, decimal(10,0), not null)

I am creating a table on SQL Server. One of the columns in this new table contains whole integer as wells as decimal values (i.e. 4500 0.9876). I currently have this column defined as Decimal(12,4). This adds 4 digits after the decimal point to the whole integers. Is there a data type that will have the decimal point only for decimal values and no decimal point for the whole integers?

Hello.
My database stores the decimals in Spanish format; "," (comma) as decimal separator.
I need to convert decimal nvarchar values (with comma as decimal separator) as a decimal or int.
Any Case using CAST or CONVERT, For Decimal or Int gives me the following error:
Error converting data type varchar to numeric
Any knows how to resolve.
Or any knows any parameter or similar, to indicate to the Cast or Convert, that the decimal separator is a comma instead a dot.

Hello!
I would like to cast (convert) data type decimal(24,4) to
decimal(21,4). I could not do this using standard casting function
CAST(@variable as decimal(21,4)) or CONVERT(decimal(21,4),@variable)
because of the following error: "Arithmetic overflow error converting
numeric to data type numeric." Is that because of possible loss of the
value?
Thanks for giving me any advice,
Ziga

I wanted to convert a dataset from vb.net (2.0) to an .XLS file, by MS Jet. My national standard is using decimal commas, not decimal points for numbers signing the beginning of decimal places.
But the MS Jet Engine uses decimal point,in default. Therefore, in the Excel file only string formatted cells can welcome this data, not number formatted.
How can I solve or get around this problem? (with jet if it possible)

Hi all,
I am designing some reports for a German branch of my company and need to replace decimal point with a comma and the thousand comma seperator with a decimal point.
e.g.
‚¬1,500,123.00 to ‚¬1.500.123,00
Is there a property that I can change in the report designer to allow this to happen or is this something I need to convert in a Stored Proc.
Any help would be much appreciated
Thanks!

I need to store decimal values: decimal(20,15) in my SQL Server 2005 database.
I load data from flat file, convert it using Data Conversion Task to decimal(with scale: 15) and try to save it using OLE DB Destination.
It works fine for 4 digits after the decimal (like 1.1234), but always failes for more than 4 digits (1.12345).
Is the decimal limited to scale 4 ???
Thank you for your help!

Hi,
I am having a file in which amount fields are given in a Packed Decimal format. Can anyone suggest me how I can read this data element from the file and convert it into SQL decimal datatype.
File is a fixed length. All the amount fields are given in Packed Decimal Format and rest of the fields are given in text format.
How can i identify and convert only those packed decimals using SQL/.Net.
Example : a row in a file that has some packed decimals
158203508540188236252EUR20BZK0030 Å“&
20060715 0001010100010101
Please help!

Hello,
I have been trying to develop an automatic way of programmatically accessing datasources and performing some predefined(-supported) processing on them.
The question I would like to ask you people has to do with numeric fields. What exactly is precision? Is it the maximum length in digits of a field, or is there more to it? What about a "field's scale", what is it and how does it affect a field's value handling?
Thank you very much,
Dave

Can you have different scales on a bar chart. I want to chart sales and quantity. Oracle lets you label the top of the bar chart as money and the bottom as quantity.
I am dividing my sales by one million and quantity by one thousand to make them similar in size on the same chart. I am using the sum of the sales/1000000 as a point label. Is there any way to limit the number of decimal places displayed. Currently it is displaying something like 1.94889312043; 1.95M would be better.
Thank you.

I'm considering options for a large scale data warehouse. Even though SQL can theorectially scale to 10 Terabytes plus, in practice - will it be able to do it? Has anyone else actually done it? Or should Oracle be used?

Hi, how do I change the scale of x axis to a larger time scale than the data ?
Data is in quarters and I want that to be displayed in a line graph, but I want the labels to show hours
(it becomes messy otherwise when showing several days)
Thank You,

Our topology:
Internal corporate network domain utilizing Integrated Windows Authentication between local workstations and the web and database servers. (domain similiar to: http://reports.ourdomain.com)
Machine #1: Windows 2003 Server w/SQL Server 2005 (SP2 and hotfixes applied) running SSRS.
Machine #2: Windows 2003 Server w/SSRS only. (pointing to the SQL DB on Machine #1)
Machine #3: Windows 2003 Server w/SSRS only. (pointing to the SQL DB on Machine #1)
Device #1: Arrowpoint load balancer for Machines #2 & #3 (w/sticky sessions).
We recently added 2 web servers and configured them to load balance the web requests to a seperate SQL Server machine. (the load balancing is done thru an Arrowpoint device not Microsoft NLB)
The installation of reporting services (on Machine #2 & #3) went smoothly and the configuration was a breeze. But we could not access the "http://reports.ourdomain.com/Reports" directory for reporting services on the 2 web server machines. We received the "401.1 - Unauthorized" http error.
Since we were using a domain name to access the report server we made sure to update the <URL> tag in the config files.
File location 1:
C:Program FilesMicrosoft SQL ServerMSSQL.2Reporting ServicesReportManagerRSWebApplication.config
<ReportServerUrl>http://reports.ourdomain.com/ReportServer</ReportServerUrl>
File location 2:
C:Program FilesMicrosoft SQL ServerMSSQL.2Reporting ServicesReportServer
sreportserver.config
<UrlRoot>http://reports.ourdomain.com/reportserver</UrlRoot>
We still received the error, so then we added a couple of entries to the HOSTS file on each web server:
File location -->
C:WINDOWSsystem32driversetcHOSTS
In order for the load balancers to "see" themselves from the domain reference we had to update the HOSTS file
on each web server to have the domain name "reports.ourdomain.com" point to the IP Address of the specific web server.
(we also added the IP of Machine #1 just to be safe):
MACHINE #2's HOSTS file:
127.0.0.1 localhost
10.10.0.1 Machine1
10.10.0.2 reports.ourdomain.com #IP of Machine2
MACHINE #3's HOSTS file:
127.0.0.1 localhost
10.10.0.1 Machine1
10.10.0.3 reports.ourdomain.com #IP of Machine3
Then the web servers were able to authenticate the users using IWA and NTLM
and we could access the report servers normally. Even the the scheduled reports
were being load balanced and emailed from the web servers which we didn't
expect to happen. (pretty cool!)
I hope this helps someone else as it tooks us about 4 days to figure this out.

We're about to put together a db solution for storing and searching large quantities of documents, with SAS running on top of it. Ultimately this is going to be a data mining project. We're talking about 2 million docs per year, ranging from 1 to possibly hundreds of pages of text per doc. We'll be pulling down roughly 40,000 docs per week, most likely XML, HTML, or SGML format. The user base is actually pretty small - probably no more than 5.
My gut feeling is to go with DB2, but to be fair I wanted to see if SQL 2005 would be up to the task. I'm not very familiar with the current version, but I udnerstand there have been some big improvements in scalability. It is the policy of SAS not to make recommendations. Does this sound like something SQL 2005 could do well, or should I stick with my initial plan and use DB2?

Hi All,
Is there a way to set a MONEY datatype to a scale (decimal places) of 2?
The default is set to 4 and I can't seem to find any resources on how to change it.
Do I have to add a check constraint to manually round to 2 decimals??
That seems unneccessary.... but if it is, boo-urns to sql server.
thanks!

I have a question about Report services scale out deployment.
In the technet document it states that reporting services must be Enterprise edition for scale out deployment functionality, does anyone know if the database engine has to be Enterprise also, or can it be standard edition?
Here is the article excerpt from technet:
The Reporting Services edition must be Enterprise, Developer, or Evaluation. Standard edition does not support a scale-out deployment. You can create a scale-out deployment using a combination of editions as long as the edition supports the scale-out feature.
Future guru in the making.

}
}
}
}
catch (Exception e)

throw e;
}
return SqlDecimal.ConvertToPrecScale(retvalue, 12, 3);
}
};
The value in the record is a decimal 12,3 which is 0.950 and when it is returned from this UDF it is 1. Using the debuger the value is 0.950 until it gets to the calling program were it
is 1. I have looked for an answer all over the place with not much luck Can anyone help I will be in their debt.

I have a case. I have 3 numeric fields and 1 category field to be displayed on bar chart reports. the problem is 2 of the 3 numeric fields have significant different scale value. so I need to add additonal scale at the right side of bar chart to represent 1 numeric fields + the 2 other numeric fields at the left side scale (Y). Please advice. Thanks.

Hi,
I'm attempting to constrct a bar chart with the Gray Scale Plaette. All the other plaette works fine. However, for the gray scale one, the patterns just go random. It doesn't follow the legend. Have I done something wrong here?
If there is no way to get around this, can I construct one manually? Just wonder how can I do that, cos I want to get some report printed out.
Thanks,

I have a stored procedure which will bring me back the Min, Max and Mean of different result sets. What I want to do with the Y-Axis is set the Min scale value of the chart to be Min -%5 and the Max scale value to be Max + 5%.
Is there a way to change the Y-Axis values at report run time without spitting my own RDL?
