Help Altering Database Table From NULL To NOT NULL
Jun 28, 2004I would drop and add the table but the data can't be deleted. So if anyone could help with the statement it would be greatly appreciated. Thanks
View 7 Replies View RelatedTransact SQL :: Database Null Value And String Null
Oct 27, 2015We 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 .
CaseÂ
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) Â 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"?
Cannot Set Connection Property Of Backup Database Task If Connection String Is Customized In Connection Object
Aug 23, 2006I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.
Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.
Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.
Is this an intrinsic issue?
Oracle Acquire Connection For Ssis Return Null
May 16, 2007Hi All!
I'm writing a custom component in c# for SSIS and I have a problem with AcquireConnection...
I wrote this code:
public override void AcquireConnections(object transaction)
{
if (ComponentMetaData.RuntimeConnectionCollection[0].ConnectionManager != null)
{
ConnectionManager cm = DtsConvert.ToConnectionManager(ComponentMetaData.RuntimeConnectionCollection[0].ConnectionManager);
ConnectionManagerAdoNet cmAdo = cm.InnerObject as ConnectionManagerAdoNet;
if (cmAdo == null)
throw new Exception("The ConnectionManager " + cm.Name + " is not an ADO connection.");
this.conn = cmAdo.AcquireConnection(transaction) as OracleConnection;
}
but the 'conn' is ALWAYS null...
I tried
this.conn = ((IDTSConnectionManagerDatabaseParameters90)cmAdo).GetConnectionForSchema() as OracleConnection;
too, but no result: the 'conn' is null again...
If I use oledbconnection or sqlconnection instead of oracleconnection the method works fine... I really don't understand
could you help me plz?
Problem With Isnull. Need To Substitute Null If A Var Is Null And Compare It To Null And Return True
Sep 20, 2006Hey. 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)
AND DR.languageid = isnull(@inlanguageid,null)
AND DR.[ID]= @ID
)
go
set ansi_nulls on
Login Failed For User '(null)' Error When Opening A SQL Connection
Jan 16, 2005Hello 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:

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,

Trusted SQL Connection Impersonation And Login Failed For User '(null)'.
May 24, 2006Hello All,
Login failed for user '(null)'.
I know this issue is all over the forum, however i have not found any posts that help me resolve the issue.
Situation:
I have an ASP.NET 2.0 application hosted currently on XP pro(will be moving to 2003 Server) which connects to a SQL 2000 database that resides on a different server. I have taken the following step to implement my security.
Given my account permissions to the database
Put the following in my web.config
<add name="MyName" connectionString="Data Source=MyServer;Initial Catalog=MyDatabase;Integrated Security=SSPI" providerName="System.Data.SqlClient" />
<authentication mode="Windows" />
<identity impersonate ="true" />
I have set IIS to use integrated authentication and removed anonymous. The application works when run from the web server but not when run from a remote machine.
Thank you for any asistance,
George
I Am Also Getting: Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection.
Nov 25, 2006Hi, am having the error above in my Subject Line. I seem to have the problem on my host web service, they have IIS 6.0 on a 2003 Server, and SQL 2000 and SQL 2005 on another server that I connect to seperately. I am using asp.net 2.0 and SQL 2000 Desktop version. I am in the very basic beginning of this website development, all I am trying to accomplish here is to enter in a login and password and be redirected to another webpage. This works on my local laptop with XP Pro, but when I try it on the server that I host my website on, I am getting this error.

Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection
Jan 18, 2007Hi I have am developing on xp machine with iis 5.1 and trying to connect to a seperate windows 2003 machine with mssql 2000 installed.I would like to use a trusted connection and I added an asp account on the sql server with permissions to the database and also edited the security tab on IIS to have this account. I unchecked allow IIS to control this password. When I look in the event viewer on my local machine I get an error:Process information: Process ID: 2388 Process name: aspnet_wp.exe Account name: MACHINENAMEASPNET Exception information: Exception type: SqlException Exception message: Login failed for user '(null)'.

Mar 26, 2007Basic setup
IIS 6 with ASP.Net 2.0, Integrated Windows Authentication turned on (anonymous turned off)
SQL Server 2000 with Windows Only Authentication on (SQL Server authentication turned off)
web.config file contains the following relevant entries:<identity impersonate="true" /><authentication mode=Windows" />
connection string:Data Source=[server name]; Integrated Security=SSPI; Initial Catalog=[database name];
When I run my query on my development server, it runs perfectly. When I run it on the production server (which is just an exact xcopy of the development web site), I get the "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection" error. I have verified that the settings I listed above are the same on both sites. What else should I check for?
I placed some test code on the page that outputs the current logged on user and the current asp.net user, and everything seems fine (both usernames are the same - the expected domainusername of the impersonated user who logged in to the site), so I don't know why the database would say the user was null. My test code for outputting the user is below:
string authUserName = User.Identity.Name;string aspUserName = System.Security.Principal.WindowsIdentity.GetCurrent().Name;Response.Write("You are: " + authUserName + "<br/>");Response.Write("This page runs as: " + aspUserName);

Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
the web application on IIS server, windows 2003 - the database on a different server windows 2003, sql server 2000.
Regaeding that we have proxy server, one firewall.
I tried to do the following steps with no use :(
1. Create a Domain Account with priveleges similar NETWORKSERVICE (windows server 2003).2. Grant this Domain Account (DomainName/NETWORKSERVICE ) access in the SQL Server Database for the necessary databases (created a new login for this user and gave it the privillage creator, read, write)3. <identity impersonate="true" userName="DomainNameUserName" password="password" />The second method is to simply set identity impersonate to true and assign the username and password in the IIS.1. Type inetmgr from your command prompt and give enter.2. This would open the IIS Control Panel.3. Expand the appropriate nodes and select the Virtual Directory of your application.4. Right Click and select Properties.5. Switch to the Directory Security Tab.6. Under Anonymous access and authentication control click Edit7. Check the Enable Anonymous access in case you want people to access the application without logging in with Windows Logon Screen.8. Uncheck the Allow IIS to control password and enter the DomainName/UserName and Password in the respective boxes. Usually IIS uses IUSER_MACHINENAME credentials for Anonymous access.9. Uncheck if any other authentication mode is checkedI did the previous step exactly like that. and the error still come.I remind you again we have a proxy server with one firwallI dont running under https X
My connection string is: <add name="LocalSqlServer" connectionString="Data Source=database server IP; Initial Catalog=database name; Integrated Security=True"; UID="sa" ; pwd="password"; providerName="System.Data.SqlClient" />Please find me a solution

Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection.
Jul 20, 2005Anyone,I have a user "john" whose machine is part of the "job" domain. He istrying to establish an odbc connection to an MS SQL 2000 server on the"school" domain. He uses Windows authentication to establish the odbcconnection however it gives the error "Login failed for user '(null)'.Reason: Not associated with a trusted SQL Server connection."I am guessing that the odbc connection is trying to pass thecredentials of jobjohn to the sql server. And since the sql serveris on the school domain it expects the credentials of schooljohn. Isthere anyway to specify the username and password so that this willwork even though the servers are on different domains without havingto trust the domains? Thanks in advance forany help on this!!Tony

Mar 28, 2008Hi, I have been working on this for a few days now. Read enough searchs on line. Still not working.
I have a web IIS 6.0 server and sql server 2005 both on the same Windows 2003 server. I have an ASP.net 2.0 application try to access the database, getting the error message as describer above.
By the way, the app is an internet application, so can not using window integrated security.
The config for the ASP .net application is like this:
Enable anonymous access using the IWAM_machine local account.
None of the authentication method is checked.
The app pool is also set to use the identity of the IWAM_machine account.
In sql server, using the mixed mode acess.
Added the IWAM_machine account, granted the account access to the databases needed
The app web config is set as:
<identity impersonate="true"/>
<authentication mode="Forms">
<forms name="ApplicationAB.ASPXAUTH" loginUrl="/ApplicationAB/login.aspx" />

SQL Security :: Login Failed For User Null / Not Associated With Trusted Server Connection
Jun 19, 2015Any way to find out who's causing "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection." error in SQL Server error logs?
View 7 Replies View RelatedLogin Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection.
Dec 11, 2007
My company is using classic asp pages for clients to sign in. A COM object is used in the page to do members and lists management job. The database server(SQL 2000) and web server(Windows server 2000) are on different machine.
Now I am laungching a project which wrap the COM into class so that we can upgrade our existing webforms to .net based. The folder which runs the .net website is set as anonymous access, and the username is set to a domian user as "POOHCORNERUM52API". I ran an asp page which is ok.
However if I runs an .aspx page even with very simply sentences It runs into error page like:
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
I googled on the internet, some pages suggest that .net pages are running under aspnet account, we need to impersonate to run that page with €œPOOHCORNERUM52API€? account, but the problem still exists even we do that impersonating like this:
<identity userName="poohcornerUM52API" impersonate="true" password="xxxxxxx" />
And on the SQL server I can see the user poohcornerUM52API is existed in the logins:
POOHCORNERUM52API Windoes User Permit master English
I ran the SQL profile to filter those with fail logins, and the event is captured however the field NTUserName and LoginName fields are empty.
Since I have done the impersonating, the page is running with the user "POOHCORNERUM52API", why those two fields are empty? I guess that is why the error come from.
If any one can help me out of this problem will be greatly appreciated.
Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection.
Oct 24, 2006I am receiving the following message when connecting via query analzyer to SQL server using windows authentication.(error 18452). I have a login created with the sys admin server role on the server. When I connect using SQL authentication it works.
I added myself to the local admin group on the server, this allows it to work. The same situation is seen with another user.
I am using windows 2000 sp4 server and SQL 2000 SP3, connecting from NT4. I get the same issue if I use TCP or named pipes. We have been using SQL security but are moving to windows authentication - but this issue is stopping us.
I have checked and upgraded my version of MDAC to match the server version 2.7 (sp1)
Any help would be much appreciated.

Err Msg: Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection.
Mar 26, 2007I have a single user receiving this error msg on a web page of our Intranet web app after they change their password. The user can access the web app just fine until they interact with this particular page. This page accesses the database while data is entered via an ADO connection. (Classis ASP)
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
The user has recently received a new desktop and the problem persists. The database login account created for the user has been deleted and recreated with no change.
We are running SQL Server 2000 with SQL Server and Windows Authentication enabled.
Connection string: Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=ProductionDatabase Data Source=ProductionServer
Our solution has been to change the user's password back to their old password.
Any ideas?
Thanks.
Edit: I am not entirely sure this is a SQL Server issue but I am starting here.

How To Query For NULL In A Database
May 31, 2007
In my database, in a few tables there are NULL values in some of the columns. This is okay, but I need to know how to query for nulls. For example I tried the following query but it did not work:
select * from Employee where DateOfBirth =NULL
This did not work so I also tried the following:
select * from Employee where DateOfBirth ='NULL'
Neither of these worked. Can someone help me out?

View 5 Replies View RelatedHow Do We Store Null In The Database
Jul 12, 2007Hi
I want to know how do we store null in the database
i know Null is unkown value
but it has to be something so the SQL server can know its null ( computer only knows 0s and 1s )
is it pointers and null does not have a pointer?
or do we store something physically?
an example : we have string(varchar) column that has this value in it "Joey Tribbiani" that means in the hard disk we will see 14 bytes "Joey Tribbiani" in there, if we changed the value to "Monika" the 14 bytes will be replaced by 5 bytes "Monika", if we changed to empty strike then we will have 0 bytes ""
now if changed it to become NULL what is going to happen to the hard disk, what is going to be in there physically??
may anyone help me in this?
many thanks

Null Entry In The Database
Jan 31, 2008
I am using a script component to retrieve some values from a server. This script component using Script task which uses VB.NET code. I have tested the VB.NET code and it returns a non null value for a string field 'sentence'. The 'sentence' feild is then passed on to an OLE DB Command transformation to be stored into the database along with a couple of other feilds.
The OLE DB Command transformation uses a stored procedure to store these feilds into the database. But when I check my table in the database, all other feilds are stored properly other than the 'sentence' feild which is null.
I am wondering what could be causingthis problem.
Thanks
Database Tables And NULL Fields
Nov 17, 2006Hi there,
I have a fairly generic question regarding database design.
I am working on my first database using SQL Express.
I am testing the database by inserting records into the pre defined tables.
Sometimes I forget to input text into a non null field. When
this happens it displays an error and then skips a few rows
which makes my row numbering messy. For example say I have
Row 1, Row 2 Row 3 all nicely formatted but on Row 4 I make a mistake
this row then disapears and their is gap between 3 and 5 where 4 was.
Although I am just testing, I was wondering what happens in a real
scenario if an inexperienced data input person makes a few mistakes it
makes the database numbering systems look bad. In this case
is it common to make most fields NULL to allow for admin errors??
Using SqlDataReader.GetString When Value In Database Might Be A NULL
Jun 8, 2007I am currently using the following code to populate fields in a form EditUserNotes.Text = EditUserReader.GetString(2); which works just fine (the datatype in the database is 'text') as long as the data stored in the database is not null. If the data is null, I get the error: Data is Null. This method or property cannot be called on Null values. which is really annoying as there are times when the data stored in the database is legitimately NULLI can use the following code to fix the problem, but it seems less elegant EditUserNotes.Text = EditUserReader.GetValue(2).ToString() is there really a difference between the GetString and the GetValue(x).ToString() methods or are they interchangeable?
