Convert Float To Nvarchar
Feb 15, 2008I have a data type float with a value of 10000487930 that I'm trying to insert into a data type nvarchar and am getting the result of '1.00005e+010'. I've tried cast(field as nvarchar) however this is not working. What might fix this? I cannot change the insert table data type.
View 3 Replies View RelatedConvert Ntext To Nvarchar For ORDER BY?
Jan 22, 2005I need to sort by an ntext field, but it won't let me do it.
However, if I cast the field as nvarchar(100), I can use ORDER BY on that.
Is there any reason that this is a bad idea? In my testing, ordering by a converted ntext field was actually *faster* than ordering by an nvarchar (same data in the fields).

SQL Field Convert Nvarchar To Datetime
Dec 4, 2007Hi everyone.
So as the subject says, I have a few fields that are nvarchar but hold date information. Most of these fields I have been able to move to datetime easiliy enough, simply by going into edit mode for the table and converting the fields to datetime. But 1 field is giving me problems I keep getting this error.
quote:- Unable to modify table.
Arithmetic overflow error converting expression to data type datetime.
The statement has been terminated.
I really dont know why I'm getting this error, but I"m assuming it may have to be something like one of the records may not be in date format. But I don't know if this is the case and I don't know how to locate where my problem is coming from.
Any guidance is greatly appreciated.
Thanks.
SELECT TOP And Convert Nvarchar To Decimal
May 21, 2008I have the following code:
INSERT INTO Reports_PI_Recent
SELECT TOP(13)* FROM Reports_PI
ORDER BY RecordKey desc
problem is that the data I am trying to insert is of the type nvarchar. eg: 06.50
I need it to be converted to type decimal (or float) before it is inserted in the new table.
Is there a way to do this within the SELECT TOP expression?
Convert Nvarchar Values To Decimals
Feb 1, 2008I'm new to SQL so please walk me through this step by step.
All the columns in my table have a data type of nvarchar, however, some of them need to be changed to decimals.
Here's an example of what my table (cicc.972file) looks like now
Account nvarchar(8) Balance nvarchar(8) Percent nvarchar(5)
45678935 459600 03500
78965215 005643 10000
and here's what I need it to look like
Account Number Balance Percent
45678935 4596.00 0.3500
78965215 56.43 1.0000
This seems like it should be ridiculously easy, but I keep running into road blocks. Like I said, this is just a sample from my table. My real table has 90 columns in it and about half of them need to be changed to either a dollar representation or a percent.
Thanks for you help!

Convert Nvarchar Values To Integer
Mar 13, 2007I have imported a text file with various data into sql table. all these values have been imported as nvarchar. I need to convert these into Integer. the format of the values is 10length i.e. 0000000.00.
example of data:
0001028.99 - needs to be shown as 1028.99
222.00 - needs to be shown as 222.00
0000190.89 - needs to be shown as 190.89
2708.99 - needs to be shown as 2708.99
00000-50.99 - needs to be shown as -50.99
-109.79 - needs to be shown as -109.70
as you can see some of the values have leading zeros and some don't.
i have tried converting from nvarchar to int and i get the error cannot convert nvarchar to int, i believe it may be because the data contains negative values as well as positive values.
Is there a split function or position function which i can use to extract the data? or any other methods which i can use would be really helpful.
Thanks

Convert Negative Number Stored As Nvarchar
Feb 4, 2008I'm working with a horrible database! The field I'm having issues with is a negative number stored as a nvarchar, but it's not stored in a consistent format. I need to convert the field to a decimal (9,2) but I can't because of the negative sign.
Example:
Balance
00000000
0000-413
0000-913
00-10913
00009526
I don't even know where to start to convert this. Any help is appreciated!

Convert Column From NVARCHAR(MAX) To Money And Then Back Again.
Oct 8, 2007
I need to always have a formatting of 999,999,999.00 in a column called PropertyMap9.
PropertyMap9 is always a nvarchar(max)
How do I SET a value using a CONVERT or CAST to accomplish this ?
Why does this give me a syntax error ? The PropertyMap7 set actually works and performs the calculation and sets the new value for that row, however the next line gives an error. I need all 3 columns PropertyMap9, 8, and 7 to always have the above formatting, while still maintaining the nvarchar(max) datatype in the column. HELP!
update PropertyMapValues
set PropertyMap7 = CONVERT(NVARCHAR(MAX),CAST(PropertyMap8 AS money) - (CAST(PropertyMap9 AS money)),1)
set PropertyMap9 = CONVERT(NVARCHAR(MAX),CAST(PropertyMap9 AS money))
END
Msg 102, Level 15, State 1, Procedure UpdatePropertyMap7, Line 59

Code Page Question (convert Squiggles To Korean And Chinese, Store In Nvarchar)
Jan 17, 2008Hi all,
I spent about an hour searching the forums and the web but could not find a solution. Bob Bojanic, if you are around can you answer?
I have a DB that stores WW data for company names in a varchar
I don't have control over this DB, other than to pull data from it
I have an SSIS package that grabs WW data in a single pull using a system account
I have an Execute SQL task that runs a sproc to stage the data
I have a Data Flow Task that then copies the data to another server (where I need it)
The destination columns are nvarchar. The source columns are varchar.
Some countries (such as Korea and China) end up with ASCII gibberish (because of code page issues).
I have a solution that involves pulling the data, BCP the pulled data to a text file, then re-import with the correct code page, and delete the gibberish. BUT, I'd like to do this as part of the pull if possible (without any data duplication).
I've tried modifying the CodePage properties for both the Staging step (Execute SQL task running a sproc) and the Source & Dest columns for the Data Flow Task with no luck. Can anyone assist? Thanks much!

Cast Or Convert Nvarchar With Comma As Decimal Separator To Decimal
Apr 29, 2008Hello.
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.
Floating Point Type??
Jan 21, 2008I 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);
Floating Point Calculations...
Nov 9, 2001Hello 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

Floating Point Exception
Oct 8, 2007Hi.
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

Should Floating Point Calculations Be Doing In Sql Or C#?
Jul 20, 2005Hi,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!

Returning A Floating Point Average
Jan 20, 2008Hi 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!
Query: Getting AVG() Of An Integer Column As A Floating Point
Feb 12, 2004I 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!

Floating Point Error - Order By Mystery
Oct 27, 2006I'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

Compare Nvarchar(10) With Nvarchar(1000)
Sep 4, 2007I had this question for quite a long time.
It seems the latter one don't take any extra storage space than the previous one.
As long as the real string length is less than 10.
Is that mean the latter one not cost anything?
I once heard the different is when they are in memory. But not sure of it.
Can anyone explain it and provide some official reference on it?
Thank.
