For example, I have a float datatype field with a value of .2501
I select using ROUND(Field,3) and get .25 as a result, but what I need to display is .250 (three decimal places.) How can this be done?
Thanks,
Paul
I can't take full credit for this. I want to share this with Jeff Moden who did the important research for this calculation here.
All I did was just adapting some old code according to the mantissa finding Jeff made and optimized it a little
Some test codeDECLARE@SomeNumber FLOAT,
@BinFloat BINARY(8)
SELECT@SomeNumber = -185.6125,
@BinFloat = CAST(@SomeNumber AS BINARY(8))
SELECT@SomeNumber AS [Original],
CAST(@SomeNumber AS BINARY(8)) AS [Binary],
dbo.fnBinaryFloat2Float(CAST(@SomeNumber AS BINARY(8))) AS [Converted],
@SomeNumber - dbo.fnBinaryFloat2Float(CAST(@SomeNumber AS BINARY(8))) AS [Error]
And here is the code for the function.CREATE FUNCTION dbo.fnBinaryFloat2Float
(
@BinaryFloat BINARY(8)
)
RETURNS FLOAT
AS
BEGIN
DECLARE@Part TINYINT,
@PartValue TINYINT,
@Mask TINYINT,
@Mantissa FLOAT,
@Exponent SMALLINT,
@Bit TINYINT,
@Ln2 FLOAT,
@BigValue BIGINT
SELECT@Part = 1,
@Mantissa = 1,
@Bit = 1,
@Ln2 = LOG(2),
@BigValue = CAST(@BinaryFloat AS BIGINT),
@Exponent = (@BigValue & 0x7ff0000000000000) / EXP(52 * @Ln2)
WHILE @Part <= 8
BEGIN
SELECT@Part = @Part + 1,
@PartValue = CAST(SUBSTRING(@BinaryFloat, @Part, 1) AS TINYINT),
@Mask =CASE WHEN @Part = 2 THEN 8 ELSE 128 END
WHILE @Mask > 0
BEGIN
IF @PartValue & @Mask > 0
SET @Mantissa = @Mantissa + EXP(-@Bit * @Ln2)
SELECT@Bit = @Bit + 1,
@Mask = @Mask / 2
END
END
RETURNSIGN(@BigValue) * @Mantissa * POWER(CAST(2 AS FLOAT), @Exponent - 1023)
END
Thanks again Jeff!

I have some engineering data in my table and the db designer is representing it with a float datatype. Here's what is happening. If I query on a record based on id num and get a row and put it in text boxes in my Windows App, min_riv_hd_dia (the float) is 0.026<14 zeroes>2. If I try to query and get that same record again but this time based on id num and min_riv_hd_dia equal to 0.026<14 zeroes>2, I get no row found. If I just do a select on this row based on id number, sql server displays it as 0.026. But if I query with 0.026 as my value, still the row is not found. If I query min_riv_hd_dia > 0.026, the record is found.
So my question is, how can I tell the exact value that must be input in my search criteria in order to find this row?
Thank you so much if you can help!
I'm using this query to sum the values. The cost column is a float datatype and what could I differently do here to sum the cost. I'm unable to sum the cost.
Also is there any way I change the datatype to int for Cost column without losing the data.

group by ID
Hi,
how to convert nvarchar datatype to float?
Regards

I am using sql express 2005 and sql server 2005 with C# 2.0.
I am a bit confused about which data type i should be using for several fields.
Right now I am declaring all of my fields in sql server as float for everything except for money fields which are using money.
When loaded into C# these fields are converted to double and decimal because C# does not have a float datatype.
Should I be using Decimal or Double for everything instead?
Here are a few examples
QtyInvoiced (float) - holds the number of items invoice
possible values look like this 1.0, 1.25 or 1.5
PercentDiscount (float) - holds a percentage
possible values look like this
10.25, 20.50, 50.00
I appreciate the help.
In SQL Server for a field of datatype float(8),
if i insert a value 2.62 , it saves it as 2.6200000000000001
like so for other values also.
But in frontend i can see the right values.
Could any of you help me in fixing up this issue?
Thanks in advance.

Hi,
I have a excel file and i am trying to import zip codes to the database... but the some of the zip codes start with 06902 but the excel file treats them as float but i want to treat them as varchar...
How can i do it.

Hi,
When i try to insert a value in to a field of datatype float(8), it is storing the wrong values(approximate values).
For example, if i try to insert 2.62 , it takes it as 2.6200000000000001
But i can see the correct values displayed in the frontend.
Heard that there is a fix available for this issue.
Could any of you help me in getting the details about that fix?
Thanks in advance.

What is the difference between Money and (Float or Decimal) Datatype. If we use Float or Decimal instead of Money, will we loose any functions..?
View 4 Replies View RelatedI have this problem of inserting my query into database field. My code is as of below.
The @AVERAGESCORE parameter is derived from
Dim averagescore As Single = (122 * 1 + 159 * 2 + 18 * 3 + 3 * 4 + 0 * 5) / (122 + 159 + 18 + 3 + 0)
and the value returned is (averagescore.toString("0.00"))
However, I have error inserting the averagescore variable into a field of datatype float during the transaction. I have no problems when using non transactional sql insert methods. What could be the problem?
Try
Dim i As Integer
For i = 0 To arraySql.Count - 1
myCommand = New SqlCommand
Dim consolidatedobjitem As ConsolidatedObjItem = arraySql(i)
myCommand.CommandText = sqlStr
myCommand.Connection = myConnection
myCommand.Transaction = myTrans

.Add(New SqlParameter("@AVERAGESCORE", consolidatedobjitem.getaveragescore))
End With

Next
myTrans.Commit()
myConnection.Close()
Catch ex As Exception
Console.Write(ex.Message)

Is there a way of converting a datetime data type in the form [DD/MM/YYYY HH:MM:SS] to an integer containing just the time in the form [HHMMSS].
View 1 Replies View RelatedWe are on SQL Server 2012 and I was wondering if you store the values in the columns with "date" or "datetime" datatype in MM/DD/YYYY format? Currently I am storing them as Varchar(10) using the Cast & Convert function to preserve "fomatting" but it would be great to do that in the date/ datetime datatype as well -- is that possible?
Note that this is not for a transnational table but for a data warehouse project. I have three fields in the date dimension each with it's own usage: INT (e.g. 20151016), DATE & VARCHAR.
Need some quick help here.. The data I got from the text file use the "04/11/2007" date format and the StockDate in MS-SQL use the datetime datatype.
My understanding is that the "04/11/2007" will default to the 04/11/2007 12:00 am" format in MS-SQL.
So, when I use the sql query, how do search only for the date part of the data in MS-SQL and match it to the data from text file? I tried this SQL Query below.
--snip--
SELECT RawID FROM tblPurchaseRaw WHERE VIN = '" & sVin.ToString.Trim & "' AND StockDate = '" & dStockDate.ToString.Trim & "'
--snip--
That way, if I get a row then I know the data is there. If I don't get a row then I know the data is not there.
Bold: I get it now. It is all automatic as MS-SQL does it automatically...

How to sort table in sql2000 with ipaddress(format x.x.x.x) as column with nvarchar datatype in ascending order

Column Name: ipAddress (string data type)
ipAddress
0.0.18.1
0.1.1.2
0.0.0.1
Sql query : if I use the query
Select ipAddress from netComputers order by cast( replace(ipaddress,'.','') as numeric(12)) asc
Gives result as :
ipAddress
0.0.0.1
0.1.1.2
0.0.18.1
Where as expected result should be:
ipAddress
0.0.0.1
0.0.18.1
0.1.1.2

Good afternoon,
I have an issue with an ssis variable datatype.
The scenario is as follows:
I have a stored procedure:
PROCEDURE [dbo].[sp_newTransaction]
@sourceSystem varchar(50),
@txOut NUMERIC(18,0) OUTPUT
AS
insert into scn_transaction (sourceSystemName) values(@sourceSystem);
SELECT @txOut = @@identity
Whose purpose is to perform an insert into a table and return me the identity value of the inserted record, which I'll then use throughout the rest of my package. The identity column in the inserted table is numeric(18,0).
I execute the stored proc with the following sql with an OLE DB connection manager:
exec sp_newTransaction ?, ?
The first parameter is a string variable from earlier in the package, and the second is the output parameter. I have the following parameter mappings to the execute sql task:
User:ystxId output numeric 1 -1
User:ourceSys input varchar 0 -1
The proc is correctly called, and the row insesrted, however I get a type conversion error when SSIS attempts to map the return parameter to my package variable... I've tried all sorts of combonations, and can't seem to get it to execute.
At one point I wasn't returning a numeric, but rather an int from the stored proc, and all was well until I went to use the variable in a derived column later in the package, and the type was converted quite incorrectly (a 1 was 77799789080 or some such), indicating a type conversion error likely related to the encoding of the number.
I'd like to keep the datatypes as numeric and make ssis use those - any pointers are greatly appreciated as to what type my package variable should be to allow proper assignment of a sql server numeric type to it.
Thanks much,
B

Hi,
I imported a table from Accees to SQL 7 with data in it.
I need to modify one of the datatype columns to "datetime" from nvarchar.
I tried to convert it manually, in SQL Server Enterprise Manager tool, but it gave me an error.
I also tried, creating another column "DATE2-datatype:datetime" and updating the column with the old one.
UPDATE users SET DATE2 = DATE.. But it also faild,..
How can I modify the column?
Thank you.
HI,I have a table with IDENTITY column with the datatype as INTEGER. Nowthis table record count is almost reaching its limt. that is totalrecord count is almost near to 2^31-1. It will reach the limit with inanother one or two months.In order to avoid the arithmentic overflow error 8115, we would likechange the datatype from INT to BIGINT. we hope this will solve ourproblem.How do I approch this datatype conversion?. Since the data count ishuge, that leads to a long down time of database.we need better approach or solution for this problem?. kindly give mea better solution that will reduce the total downtime of the productiondatabase.?.Regards

Hi All,
I am stuck at one place, where I have to convert CSV format file data into SAP IDOC format file. In SSIS we don't have any such SAP adapter (though we have .NET Data Provider for mySAP suite [SSIS SAP Adapter] but this is still not fully supported by Microsoft, plus it doesn't have feature to convert data into IDOC format) that can do this. Can someone here please provide me some pointers on any third party adapters available in market to do this job or if anyone has already developed some custom approach to achieve this task?
Your quick response on this is highly appreciated.
