Aritmetic Overflor On READING A Date Value
Mar 19, 2004
I have a date in my SQL Server Database of 3/12/2204. This is, of course, 200 years after today and is not a correct value.
However, when my repeater is trying to display the records in that table, I get the following error:
"Arithmetic overflow error converting expression to data type datetime."
Here is the stack trace:
[SqlException: Arithmetic overflow error converting expression to data type datetime.]
System.Data.SqlClient.SqlDataReader.Read() +157
System.Data.Common.DbEnumerator.MoveNext() +44
System.Web.UI.WebControls.Repeater.CreateControlHierarchy(Boolean useDataSource) +504
System.Web.UI.WebControls.Repeater.OnDataBinding(EventArgs e) +48
System.Web.UI.WebControls.Repeater.DataBind() +23
Now, none if this is in my own code, and so it is difficult to put any decent error-trapping. This is all in the built-in ASP.NET Repeater and SqlDataReader classes.
Why on Earth would there be an arithmetic overflow here? Note that the original table this is coming from has the date stored in the SqlDbType.DateTime format! In other words, why is there any conversion needed?
Perhaps it is converting the data from SqlDbType to DbType, but even then, what is so difficult about dealing with the year 2204? According to BOL, the DateTime data type should support up to the year 9999!
Note that when I access the table through Enterprise Manager and change the date, the error disappears. I tried a number of over-and-under tests, and I get this error on any date after 3/19/2151!
Does ASP.NET not support dates after that? I doubt it, but does anyone have an explanation for this?
Thanks,
JK

Simply put, I have a 'Date and Time', (06/03/2006 11:40:00), passed to the SelectCommand via the QueryString. I would like to gain data that is between the supplied time and 1 hour prior.Is there a simple way to take 1 hr off the 'Date and Time" value or is it necessary to build code that parses the string then adjusts it?
The 'Time' and 'TimeStamp' entities below are both of type 'Date and Time' and all values are gained from the same sql database. I.e. the time used as the basis for selecting the hr period is from the same database as the one where the hour period will be selected from.
Any help would be great.
SelectCommand="SELECT [Timestamp], [Volume] FROM [out8$] WHERE (([CustomerLvl1] = @CustomerLvl1) AND ([Timestamp] = @Timestamp))">
<SelectParameters>
<asp:QueryStringParameter DefaultValue="TNT Express" Name="CustomerLvl1" QueryStringField="Cust"
Type="String" />
<asp:QueryStringParameter DefaultValue="20/02/2006 22:20:00" Name="Timestamp" QueryStringField="Time"
Type="DateTime" />

I have to display the last temperature reading from an activity table for all the dates in a selected date range.So if I select the date range from 09/01/2012 to 09/30/2012, the results should look like this:
Date Temperature
09/01/2012 73.5
09/02/2012 75.2
09/03/2012 76.3
09/04/2012 73.3
09/05/2012 77.0
09/06/2012 74.5
and so on.
I am using this to get the dates listed:
WITH CTE_DatesTable
AS
(
SELECT CAST('20120901' as date) AS [Date]
UNION ALL
SELECT DATEADD(dd, 1, [Date])
FROM CTE_DatesTable
WHERE DATEADD(dd, 1, [Date]) <= '20120930'
)
SELECT [Date]
FROM CTE_DatesTable
How could I get the temperature if I did a sub-query here?

Why won't this dataReader read?
Dim objCon2 As New SqlConnection()
objCon2.ConnectionString = "a standard connection string"
objCon2.Open()
Dim objCommand As SqlCommand
objCommand = New SqlCommand(strSQL, objCon2)
Dim objReader As SqlDataReader
objReader = objCommand.ExecuteReader()
Label1.Text = objReader("email")
strSQL is a select command which I've checked (using SQL Query analyzer) does return data. I know the connection string is valid (and I presume if it wasn't that it'd fail on objCon2.open, which it doesn't).
So why oh why do I get this error on the last line (and yes, there is an "email" field in the contents of the reader)
System.InvalidOperationException: Invalid attempt to read when no data is present.

I have this code that I hacked together from someone else's example. I kind of understand how it works. I just don't know if it will and i am not in a location right now to check. I was wondering if I did this correctly first, second how can it improve and should i do something different. Basically i just want to check the password in a database. I am passing the username and password to this function from another functioprivate bool authUser(string UserName, string Password){ string connectionString = ConfigurationSettings.AppSettings["DBConnectionString"]; SqlConnection DBConnection = new SqlConnection(connectionString); bool result = false; DBConnection.open() SqlCommand checkCommand = new SqlCommand("SELECT password FROM Users WHERE userName='" + Password + "', DBConnection) SqlDataReader checkDataReader = checkCommand.ExecuteReader();
if(checkDataReader.GetString(0) == Password) { result = true; } else { result = false; } checkDataReader.Close(); DBConnection.Close();
return result;}Thank you Buddy Lindsey

Is there a way, in SQL 7.0 to print out or view what's in the Transaction Log? In 6.5 you could view the table syslogs, but I don't see any documentation anywhere on how to do this in 7.0.

Hi. I want to write a function to retrieve all records from a "Parts" table so that I can read these records in .NET.
SqlDataReader reader = sqlCmd.ExecuteReader()
while( reader.Read() )
{
int x = reader["id"];
string partName = reader["name"];
// Do stuff with data here //
}
My question: How should the function be written?
Should I create a PROCEDURE and just call a SELECT statement?
CREATE PROCEDURE getPartsList()
AS
SELECT part_id as 'id', part_name as 'name' FROM parts
Or should I create a FUNCTION that returns a TABLE? If so, is this the correct syntax?
CREATE FUNCTION getPartsList()
RETURNS TABLE
AS
RETURN (SELECT part_id as 'id', part_name as 'name' FROM parts)
Thanks for reading

I do a lot of file processing and I usually run a little script I copyand paste to read directory information to see if a new file it thereand then process the file if it is. So, I decided to wise up and makea stored procedure to automate a lot of that.The pivotal step in this is that i run a command that looks like:CREATE TABLE #DIR (FileName varchar(100))DECLARE @Cmd varchar(1050)SET@Cmd = 'DIR "' + @Path + CASE WHEN RIGHT(@Path, 1) = '' THEN ''ELSE '' END + @WildCard + '"'INSERT INTO #DIREXEC master..xp_CmdShell @CmdWhen I run the stored procedure I get back the files and folders inthere that match the wildcard and all is good!!!!....Until I try to put that information into a table while calling thatstored procedure:CREATE TABLE #Files (Path varchar(100),FileName varchar(100),PathAndFileName varchar(150),FileDateTime SmallDateTime,FileLength int,FileType Varchar(10))INSERT INTO #FilesEXEC sp_GetFileNames @Path = '\isoft2ftpLegacyBilling', @Wildcard= '*.txt'When I run this I get:Server: Msg 8164, Level 16, State 1, Procedure sp_GetFileNames, Line53An INSERT EXEC statement cannot be nested.Because I use an INSERT EXEC to with the results from the @Cmd.Anybody have any ideas how I can get that information into a table?I did try to just copy the data to c: empdir.txt and then bulkimport it in. But when it runs the @Cmd to create the file it comesback with a NULL value and my stored procedure returns two sets ofvalues... which I can't do.So, I would appreciate anybody who can help.Thanks!-utah

Hi
I have a problem with SSIS in that I need to read an XML file in from a URL,which brings me back the below XML. What I need to be able to do is essentially create a single record, including the nested XML <image> into the same record. This information then needs to be entered into a database table.
What I found is that if I use a data flow component, and have an XML source pointing to this URL, it essentially creates a different output for every level of nesting. This causes me serious issues because I would then have to somehow get to the information in the <image> tag, and then get everything below that, etc, to be able to get the images related to each <stock> record. This is a pain.
I also looked at using an XML task, where I could use an XSLT to transform to the required output, however, I can't point this XML task to a URL to retrieve the XML.
If anyone has any ideas I would greatly appreciate it
Thanks
Darrell

Hi,
For our trainign data clustering models show the maximum accuracy.
We want to preset the results to our client. In order to do that we want to present what are the properties of each cluster.
For example for my predictable attribute if Cluster 9 is showing maximum population then I want to show what conditions of attributes make cluster 9 .
What is the way of doing this ?
Thanks,

I am trying to read from a datasource that is a CSV file using C#, but for some reason I keep getting an error that says:
System.Exception: System.Data.OleDb.OleDbException: Syntax error in FROM clause.
My code looks like this:
String sql = " SELECT IDnumber FROM report.csv WHERE username = @Username ";
ArrayList parameters = new ArrayList();
parameters.Add(new OleDbParameter("@Username", Username));
DataTable dt = OleDbUtility.getDataTable(sql, parameters, OleDbUtility.GetCNetIDConnectionString());
It worked with an Excel file, so any ideas on this one?
It seems like the connection string is fine...
