I have the following query:
SELECT AVG(respondent_question.answer)
Now, the 'answer' column is an integer. However, I want the query to return a floating point number with one decimal place (i.e., 5.4, 2.3)
Since the column is an integer, the query returns only an integer by rounding to the nearest integer. How can I do this? Thanks!
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);
Hello all,
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).
--------------------------------------------------------
Apart from the fact that it says 'Approximate number data types' I can't see any difference between the data type apart from the ranges.
Anyone any ideas?
Thanks

How can I truncate a floating point number to required number of decimal points
Eg:
100.642364074 to 100.64 and 67.643929847 to 67.645
Thanks.
Hi.
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.
Cheers

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?
Thanks for helping!
Hi,
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"

Please advise me how to reproduce the problem.

I'm having a problem that I think is due to corrupt data. Depending on
the column I use in my order by clause two problems are occuring.
1. No results are returned and I get this error:
A floating point exception occured in the user process.
2. Results are returned but there are a different number of rows depending on which columns I use in my Order By clause.
Examples
SELECT * FROM SymbolStats
ORDER BY calc_date, symbol
Returns - 12207 rows but only includes one of the 25 dates in the table.
----------
SELECT * from SymbolStats
ORDER BY current_hv
Returns - 0 rows.
----------
SELECT * from SymbolStats
ORDER BY average_hv
Returns - floating point error
With more conditions in the WHERE clause the number of results returned varies greatly.
The
fact that different numbers of rows can be returned from the same query
only differing in how they are ordered seems like a bug.
Does this sound like corrupt data? If so, what are the best methods for fixing it?
Thanks,
patrick
I'm getting this error:
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?

The best SQL results compare only to the fourth digit with other results. Everything else agrees to the 10th or 12th digit.
Is the precision of arithmetic calculations on SQL Server that bad, or am I doing something wrong here? Is there another more precise alternative?
I did the following. The results speak for themselves
DECLARE @x FLOAT(53) = 1.0004;
DECLARE @y FLOAT(53) = 1.0/12.0;
DECLARE @z FLOAT(53) = POWER(@x,@y)-1; -- Answer: 3.33270904724348E-05

Hi everyone....
I need a column in my table that its DataType should be as integer arrays how can I implemant it in my sqlserver table.
Any help appreciated.
When I use the AVG Function on an integer column, the result is truncated
Example:
Select AVG(field1) from table1
Field1 is an int field and has 4 rows with the values 114,115,115 and 115. This will return 114.
I can get the correct result by using the following SELECT:
SELECT CAST(AVG(CAST (field1 as decimal(18,1)))+ .5 as int) from table1
Am I missing something here? Is there an simpler way to do this?
Any help will be appreciated.

I am only querying the tables i.e. i don't have access to actually change the data tables themselves.
CAST or CONVERT throws up an error. Are there any other commands i can use at the query stage?
The data I need to convert is always actually a number. i.e. even though it is recognised as alpha numeric, the figure is a number.
I just need it to be converted to an integer so i can SUM it etc.

I have two columns, one column has a document ID and a given document can have many pages. The second column has the pages. Now I want to find out when the page number is broken. For example, if doc ID 1 has 3 rows and each of the three has 1,2,3 and then the fourth row has document 1 but the value jumps from 3 to 7 and then goes to 8,9,10 and then jumps again and starts from 17, i want to have the ranges identified.

1 3
1 7
1 8
1 9
1 10

1 Â Â 20
The result should look like :

Working on a new database where the Date and Time are stored in a Date Time Field.
Then working on an OLDER database file within the same SQL Database contains these 2 items as integers:
transDate = "71615" (July 16, 2015)
transTime = "12345" (01:23:45 AM)
How do we convert both of them into a single SQL DateTime field such as "2015-07-16 01:23:45.000" so that it can be used in a join restricting to a date time in a different SQL File that properly has the DateTime in it?
This works well for converting the transDate Part in the select statement:
  dbo.IntegerToDate(at.transDate) as transDate
  * That returns: "2015-07-16 00:00:00.000"
* The resulting data must work directly in a Microsoft SQL Server Management Studio Query using either using the "on" statement or part of the "where" clause. In other words, NOT as a stored procedure!
Also must be able to be used as a date difference calculation when comparing the 2 files Within say + or - 5 seconds.
I have quite a few tables which allow NULL values. I have to struggle a lot with DBnull Exceptions :|example: col1,col2,... are all columns of type Integer and possibly NULL. var query = from person in table select new { person.col1, test = (int?) person.col2, person.col3, person.col4, ...}; As soon as my result encounters a DBNull value.. the whole query fails. This is really bad.How would I return the valid values.. and set the keys where there is no value to a null type? (e.g. int -> 0)I tried using "(int?)" but I'm not *really* sure what it does :-) Anyway.. it has no effect :-)
View 1 Replies View RelatedHello all,
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 am dealing with what I believe is Oracle that is the source of a SQL View.
I am seeing a data type of Integer in the View, but I am not able to see what makes up that View. When I query the View, I can see that an Integer data type column is storing a blank space. I use ISNUMERIC(ColumnName) = 0 and there are a lot of rows that show as a zero length blank space, or text, or something. I just know that it is not an Integer.
I have attempted to CAST and Convert this value, but it will not. I have changed the data type on the table that is being inserted in too, and it still fails with a Conversion error. I have tried REPLACE(), but still the same conversion error.
Hey guys and gals,
I'm having a real problem with this query at the moment...
Basically I have to produce a query which will tell me the total number of people employed by the company at any given date and the total salary for all these people.
We have a people table and a career table.
People(unique_identifier, known_as_and_surname, start_date, termination_date ...)
Career(unique_identifier, parent_identifier, career_date, basic_pay ...)
Relationship people.unique_identifier = career.parent_identifier
Employees can be identified like so
SELECT *
FROM people
WHERE start_date <= DateSelected
AND (termination_date > DateSelected
OR termination_date IS NULL)
Passing the selected date to the query is no trouble at all I am just having problems with the point in time side of this.
All and any help is greatly appreciated :)
