Any Improvements To This: Cannot Apply Value Null To Property Login: Value Cannot Be Null.
Mar 26, 2007
Looks like there was a fix and then I read this fix is not a fix. Does anyone know how this can be rectified? Does it mean that only Windows authentiation is the only way it works. The Software is over 2 years old, there are no excuses.
Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go
declare
@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,
@inFileVersion VARCHAR (100),
@ExeState int
set @inFileName = 'A0006337.EXE'
set @inFileSize = 28796
set @Id= 1
set @inlanguageid =null
set @inFileVersion =NULL
set @ExeState =0
select Dr.StateID from table1 dR
where
DR.[FileName] = @inFileName
AND DR.FileSize =@inFileSize
AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)
I have two tables 1) tblCustomer (ID, Name, City) 2) tblemp (ID, NAME, Dept.ID, tblcustomer.ID) Both the tables have ID as PKA emp can be either assigned a) All customers b)single customer c) NO customer Pls note:- there will never be 2 or 3 customer linked to emp (my actuall requirement tables are different but to explain i am using the above tables) I know how to assign single customer......but had problem how to link all customers and "no customer" Please tell me if the following solution is right?1) I will manually insert a record in tblCustomer with id 0 as " all customers" and will not allow the user to delete it 2) store null in FK if it is "no customer" Also please tell me is it ok to store one more value in tblCustomer as -1 and take it as "No customer" I have a DDL in the Employee page which should be displaying the names of allthe customers with 2 extra values "ALL CUSTOMERS" and "SELECT" Select is the default value in DDL which says "NO CUSTOMER" selected yet Thank youSara
I've written some provider independent code that dynamically generates and loads DbCommands with data via Parameters and executes them within a transaction. Everything works fine until an exception occurs and then the DbCommand.Transaction property that was set goes to null, effectively killing any chance of rolling back the transaction. I've noticed this only happens when the executed command is of type SqlCommand. The OracleCommand mainitains its link to the set transaction of failure. Upon further investigation, I found that this only occurs when parameters are used but not if I dynamically generate the insert statement as a string.. For instance:SqlConnection conn = new SqlConnection(connectionString);conn.Open();SqlTransaction transaction = conn.BeginTransaction();SqlCommand comm = new SqlCommand();comm.Connection = conn;comm.Transaction = transaction; command.commandText = "INSERT INTO Table1 Values (1, 2, 3)";command.ExecuteNonQuery(); If I execute that and it fails the command.Transaction property will remain set to transaction, but in this scenario: SqlConnection conn = new SqlConnection(connectionString);conn.Open();SqlTransaction transaction = conn.BeginTransaction();SqlCommand comm = new SqlCommand();comm.Connection = conn;comm.Transaction = transaction; comm.commandText = "INSERT INTO Table1 Values (@Col1,@Col2, @Col3)";comm.Parameters.add(new SqlParameter("@Col1", 1); comm.Parameters.add(new SqlParameter("@Col2", 2);comm.Parameters.add(new SqlParameter("@Col3", 3); comm.ExecuteNonQuery(); Upon failing the comm.Transaction property gets somehow goes null and the Connection property of the transaction object also goes null.Any ideas on why this only happens with a SqlCommand but no other DbCommand?
In my report i have CNAME parameter , which allows null value. I checked Allow null value check box in report parameter properties.
when i preview the report , it displays checked NULL check box beside CNAME parameter . I want to give some meaningful name(i.e.ALLCustomers) to this checkbox instead of NULL.
I have an issue dealing with connectivity between the client and Sql Server Services or Sql Authentication. I keep receiving this type of error message:Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection. I am sure my connection string is correct within my web config file, I have something like this:Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=SSPI; The reason why I think the connection string is correct is because I have a server where my asp.net application is stored and used, this server is called server1. Server1 is connected to MS-SQL server that is installed and used on server2. When I run my application from server1 everything is perfect, nothing goes wrong, but when I run the application from my client or local machine I get the error message saying not associated with a trusted site. Now I have the web config set to <identity impersonate="true"> that will allow windows Authentication, and I set the permissions within the database to use NT AUTHORITY NETWORK SERVICE as a user, plus my own network credentials are set within user on the database, just so I could troubleshoot the problem. But I still get the error message not associated with a trusted site. Just to recap my problem, I can see the data when I run the application in Server1, but I can't see the data when I run the application from my local machine. http://server1/MyApplication.aspx <-- this is an example of the url that I enter on my local machine to acces the application. Plus I have full acces to server1, and other application are running just fine from this server. I am using visual studio 2005, but using sql 2000, with the latest service pack for windows XP pro.

When accessing a web application from an intranet.... And the web app tries to make a connection to a 'SQL Server' using the sqlconnection where does ASP.NET grab user credentials? My webpage displays web security.principal.windows.getcurrent = domainUser (displays the correct information). But the connection to sql says Null. Where is ASP.NET grabbing (retrieving) this information from? Thanks,
SQL7 server is configured to use both SQL and NT authentication. Periodically, NT authenticated users get the error "Login failed for user '(null'. Reason: Not associated with a trusted SQL Server connection." Repeating the login will eventually end in success. Microsoft article Q216848 indicates this has something to do with the version of MDAC.
We have not changed the version of MDAC on the server, but checked it and the versions are as the article states (MDAC 2.1 & SQL Driver 3.70.623).
We had a newer version on the client, but went back to the version above that came on the SQL7 CD with no luck.
Any ideas, suggestions, or similar problem experienced?

Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
It appeared nearly 20 times, then about 30 minutes after the first occurence, I noticed in my Event Viewer this error:
The registration of DNS name XXX.XXX.XXX.XX.in-addr.arpa. for network name resource 'SQL Network Name(SQLServer)' failed for the following reason:
DNS operation refused.
After that I began recieving hundreds of errors like this one:
Login failed for user 'SQL user'. Only administrators may connect at this time.
I was unable to connect to the server to see what was going on so I had to failover the server. That's why my troubleshooting is limited to error logs. After the failover, everything came up fine with no more errors. Has anyone ever encountered this before?
Hello,I have problem with linked servers (MS SQL Server 2k)- when I try to executequery(update, insert..) with linked servers, I have message Login failed foruser 'null'.

I am using a Third Party software which depends on my SQL Server 2000 for storing data. When I use Windows Security in my Third Party software, I get the following message in the event viewer of my SQL Server 2000.
Description:
18452: Login failed for user '(null)'. Reason: Not associated with trusted SQL Server connection.
When I user SA, I do not get the above error.
Any clarifications on the possibilites for getting the error is appreciated. Also let me know if we can overcome the error without using SA.
I tried the article in http://support.microsoft.com/kb/840219. But it didn't make a difference.
Im trying to make a couple of reports online for other people. My current setup is:
Machine A: SQL05 server. Machine B: ReportingServer05 and IIS 5.0 (XP machine). Machine C: Client trying to connect to Machine B and view a report. (Windows 2003)
On Machine B everything is working just fine, i can view my reports without any problems. But if i try viewing a report on Machine C, I get the following error:
An error has occurred during report processing. (rsProcessingAborted) Get Online Help Cannot create a connection to data source 'IntegrationDB'. (rsErrorOpeningConnection) Get Online Help Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection. But machine C kan browse http://machine-b/ReportServer and se the list of reports hosted, its when trying to generate the reports there is a problem. Im logged in on machine C with the same user as on Machine B.
My Shared Data Source in this VS05 project is setup to be using Integrated Security, so the "user '(null)'" part looks like Machine C dosnt supply the username, but why?
What is it that im missing in my configuration? And any addional information needed?
(First, I should explain that I am not sure whether this is the right part of the forum for this message. My apologies if I'm in the wrong place. If this is the case, could you please let me know where this post should be? Thank you.)
I have a vew that accesses data from a linked server. The view works properly in Query Analyzer but fails when run by a .Net application. The message returned is:
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
The linked server has the following attributes:
Server Type: SQL Server Security: No local logins listed. Connections are made using the login's current security context.
I've read quite a few articles about resolving this login problem. "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection. " But still can't solve mine.
I am working on a Website that can access a remote database engine which locates in the same domain. (Eventually the website and the db server would be on the same computer, but not during the development and testing.)
My code works fine when I am debugging on an ASP.NET Development Sever. I tried two users account, Windows' or SQL Server's. Both work fine under ASP.NET development server (run ASP.NET application locally).
But when I run the website from wwwroot virtual path, it throws error message:
"Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection."
Why does it this happen? And how to resolve this? Did I miss anything on local IIS side or the remote DB server?
In the flat file SampleID and Product are populated in the first row only, rest of the rows only have values for Rep_Number, Protein, Fat, Solids.
SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.
In Microsoft analysis services, I get an error that login fails for user "NULL" when I try to process/build any cubes. If I edit the connection properties, it says to use "trusted" signon. If I press the "test connection" button all is well.
I definitely have serverdatabase access otherwise. Any thoughts/insights?
Thanks,

ps: this is a sql server 2000 version of MSAS. Corresponding sql server is 2000 as well.
I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.
The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.
Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help
I run a stored procedure for which I have a return variable. The stored procedure returns the ID of a row in a table if it exists:
m_sqlCmd.ExecuteScalar();
The m_sqlCmd has been fed an SQLParameter with direction set to output. When the stored proc returns, I want to test it. Now when there IS a row it returns the ID ok. When the row doesn't exist, in my watch I have:
m_sqlParam.SqlValue with value {Null}
I can't seem to work out how to test this value out. I've tried several things but none seem to work.
This line compiles ok, but the following runs into the IF statement as if the SqlValue is null??
if (m_sqlParam.SqlValue != null).... {
// I'm here!! I thought the watch says this is null??? }
Sorry if this is obvious, but I can't work this one out!!
I am getting this error: "Cannot insert the value NULL into column 'OrderID', table 'outman.outman.Contact'; column does not allow nulls. INSERT fails." -- But my value is not null. I did a response.write on it and it show the value. Of course, it would be nice if I could do a breakpoint but that doesn't seem to be working. I'll attach a couple of images below of my code, the error, and the breakpoint error.

I've built a sample CLR function with the following declaration....
CREATE FUNCTION GetManager(@DeptCode nvarchar(3)) RETURNS nvarchar(1000) WITH RETURNS NULL ON NULL INPUT AS EXTERNAL NAME Assembly1.[ClassLibrary1.MyVBClass].MyManager
It returns the value "Unknown" as it would have for any unknown DeptCode, as-programmed.
I'm of the theory it should have returned NULL without actually firing the function? Or is this only for non-CLR items... or stored procedures, not functions?
We have a case where in we should show date based on conditions for e.g if we had a column defined as
col varchar(10) then we would show col as 'NULL' for some condition and actual value when no condition
Normaly date values are stored here e.g under col 20150901 .
Case when col>'20150901' then 'NULL' else col end as Derivedcol
Note this is an extract process and we are presenting data by pumping the data in a table .
Now there is another similar column -colz varchar(10) which stores date but doesnt have case condition so whenever date has no value its shows null which is database null.
So whats the difference between database null and string null ?
How can we show database null for the case condition instead of string "null"?
Hello everyone. I'm very new to asp.net. I've been coding in vb.net for a while now (getting my associates degree in desktop application programming) and my boss wants all of my new applications to be web based now. Well, i decided to take some initiative on this and begin a new project for my department. This is a very small project. So far, everything is coming along alright (i found an eBook that's helped me quite a bit). Everything was cool until yesterday when i tried to connect to our sql server database. I get an error message stating:
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
Because i'm testing this on my system as well as the remote system which hosts the application, i can see the error message on the remote system. Here is the error it's giving me:

You can see my SQL Connection string in there as well. Can someone please help me with this? I can post the code to the entire page as well if that would help. I'm developing this with Dreamweaver MX 2004 (i like dreamweaver MUCH better than visual studio, especially for web design/development). Thanks,
