i have a problem in tsql displaying data.
i tried to use :
[Code]....
it cause error. because it cannot convert '-' or 'error' into FLOAT
but what can i do to display charactor/string when a FLOAT type data is zero?
I want to change one of my table columns data type. Now the column data type is varchar and i want to change it to float. Updated all the column data to numeric and tried to convert the datatype with the following syntax
alter table vibration_values alter column dis_v float
but getting the error as
Error converting data type varchar to float.
The statement has been terminated.
Suprisingly every thing worked well in sqlserver 2005 and not working in sqlserver 2000.
I have a SQL Server table with a number of fields that are defined with the "Float" data type. I'm running a simple query to retrieve the data from this table and use it to populate a Data Table in my C#.net application.
I just discovered that the data type of the Data Table fields is Double, not Float as I expected. As such, when I store a value like 0.157 it ends up getting stored like this: 0.15700000524520874
I'm aware that such extra "noise" occurs when such a conversion occurs. My major question has to do with why .Net didn't set the Data Type to Float (ie. Single) when the table was first populated?
In my database, there is a column "summary" with single quot in it.I am fetching this data inside Gridview. Data is shown inside Gridview as:
<summary>"
I want single quot to be shown inside Gridview as (')for that I tried to change the code as below:
<asp:GridView ID="GridView1" runat="server" Width="100%" BackColor="White" DataKeyNames="IssueId"
AutoGenerateColumns="False" AllowPaging="True" PageSize="8" CssClass="Grid" OnRowDataBound="GridView1_RowDataBound">

When i am trying to update a text box value to data base ,say 3.1 it is getting updated as 3.09999... when iam running the stored procedure in query analyzer it is updating correctly. When i am updating the same from page , it is giving this problem. Iam using sql server 2005.
Iam using float for this
My issue is that , need to change the column name(following format "Remove first character and after 3rd character insert colon") of the gridview (which is binded with XMLTextReader). Without changing directly XML file, Required to change the column name dynamically at runtime .

I had a 14 digit create datetime and resolved datetime in float time format and I could parse the date using following conversion:
CONVERT(datetime, LEFT(CAST(CAST(is_resolved_datetime as BigInt) as varchar(14)),8)+' '+
SUBSTRING(CAST(CAST(is_resolved_datetime as BigInt) as varchar(14)),9,2)+':'+
SUBSTRING(CAST(CAST(is_resolved_datetime as BigInt) as varchar(14)),11,2)+':'+
SUBSTRING(CAST(CAST(is_resolved_datetime as BigInt) as varchar(14)),13,2))
If I were to extract only the time difference of two datetimes in hr:min:sec.
We have an application we are maintaining, cant make changes to the database, but new form was created and need to pass the values into the table now..
there are 2 columns in the table that are to store the date, but the datatype is set to float.
When i try to pass the values into the procedure in my code behind i get errors that says
"input string was not in a correct format"
my procedure is expecting float, my class method is expecting float, my parameter.add is passing it as float cmd.Parameters.Add("@sdate", System.Data.SqlDbType.Float).Value = sdate;
So im guessing that on my page code behind where im calling the insert method and passing in my textboxes, i need to make some adjustments.. just not sure what they are..
float stDate = System.Convert.ToSingle(txtSdate.Text);
Select number,empname,empfathername from emp
where number column is float data type
I need first four dights of number where it consists 10 digits.
num is 1234567890
O/P like to be
1234
We are using microsoft report in our project, in that we are showing some special character like japanese character. In rdlc file we have applied Arial Unicode MS font for that label. We are rendering this file into the pdf format.
In development environment (Window vista OS) we are able to see that unicode character properly but when we deploy on windows 2003 server then that special character shown as '????' .
Previously Arial unicode MS font was not installed on windows 2003 server, we have manually installed it after that also we are not getting unicode character in report.
I have a problem to display some russian characters into a formview but only in the Item template.
I change my insert statement adding an N' .The data are well stored into my SQL table
I have add into the web.config
<globalization fileEncoding="utf-8" requestEncoding="utf-8" responseEncoding="utf-8"/>
<authentication mode="Forms" >
The data appear well into the EditItem template but when switching into the Item template I have ???????? in place of the russians characters.
I need to convert the contents of a Textbox (which is currency) to a datatype float.
Would I convert to single?
txtPurchItemCorrectPrice.Text.Trim();

If the data is 1,454, stored as 1454 What am I doing wrong? My code:
Course = Convert.ToDouble (tecaji.ToString ()),

Norwegian character( å æ ø) does not show instead showing some strange character.

I have a variable in the database "Amount". Data type is a float, but if I write 10.00, save 10 This is not good.
I want to save the database 10,00, and not 10.
I looked up the msdn documentation and it says that InvalidUserName is thrown when it does not find the username in the database, which is fine because the user I am creating should not exist in the database. If I use test@example.com, it works, but if I try it with test.@example.com, the status from Membership.CreateUser is InvalidUserName.
View 1 RepliesI have a GridView. I am trying to make an Array or ArrayList of type structure. The vales that I want to make the ArrayList or Array (I don't know which one is more appropriate) from are points with latitude and longitude and are of type float. I have:
Point[] Array = new
Point[counter];
foreach (GridViewRow row

How to read character by character in line from text file?
View 1 RepliesI have a legacy MySQL database which stores the user passwords & salts for a membership system. Both of these values have been hashed using the Ruby framework - roughly like this:
hashedsalt =
Digest::SHA1.hexdigest("--#{Time.now.to_s}--#{login}--")
hashedpassword =
Digest::SHA1.hexdigest("#{hashedsalt}:#{password}")
So both values are stored as 40-character strings (varchar(40)) in MySQL. Now I need to import all of these users into the ASP.NET membership framework for a new web site, which uses a SQL Server database. It is my understanding that the the way I have ASP.NET membership configured, the user passwords and salts are also stored in the membership database (in table aspnet_Membership) as SHA1 hashes, which are then Base64 encoded (see here for details) and stored as nvarchar(128) data.
But from the length of the Base64 encoded strings that are stored (28 characters) it seems that the SHA1 hashes that ASP.NET membership generates are only 20 characters long, rather than 40. From some other reading I have been doing I am thinking this has to do with the number of bits per character/character set/encoding or something related.
So is there some way to convert the 40-character SHA1 hashes to 20-character hashes which I can then transfer to the new ASP.NET membership data table? I'm pretty familiar with ASP.NET membership by now but I feel like I'm just missing this one piece. However, it may also be known that SHA1 in Ruby and SHA1 in .NET are incompatible, so I'm fighting a losing battle.
For Example, "E0001"
Everytime it will automatically incremened by 1.
"E0001" -> "E0002-> "E0003" and so on.
"E0010" -> "E0011" and so on.
"E0100" -> "E0101" and so on.
When i try to pass this string "- !@#$%^&*()_+|}{:"?><<>?/.,';[]`" as a parameter to SQL Server Reporting it crashes. Here is code sample
ReportParameter[] ReportParams = new ReportParameter[1] { new ReportParameter("Name", HERE-COMES-SPECIALSTRING)
IS there any way to pass special character safely like in SP's we use @ sign for parameter name
