Hello, everyone!
I have some fields that must have data entered into them(i.e they shd not be left blank) & since the data has to be different almost everywhere I cannot set a default also. However I have defined these columns as NOT NULL, but still when data is entered they accept null values. WHY?
Please help!
Thanks in advance!

Hello.
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
And it works as expected, except when I use NULL:
DECLARE @MyManager nvarchar(1000)
EXEC @MyManager = dbo.GetManager NULL
PRINT @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?
I currently have a stored procedure that looks something like this SELECT * FROM tblQuestions WHERE Title LIKE ISNULL('%'+@Name+'%', Title)I have a form that supplies this value. This statement should make it so that if a NULL value is passed in, then it will return all the rows, if some text is specified, then it will not. On my SQLDataSource on the page where the parameter is supplied I have set ConvertEmptyStringsToNull to True, but when I say in my code,SqlDataSource1.SelectParameters.Add("@Name", TextBox1.Text);It won't give me back any of the rows, I know that the stored procedure works fine because I can get it to work by a basic query and other testing on it, so somewhere in my form, the NULL value isn't being passed, I belive that it is passing an empty string and I don't know why. Thank you in advance /jcarver

Hi,
I have a problem with a SQL that check if a date column IS NULL.
On one server the check work ok but on another (the same data is on both - restored copy) the check does not find any NULL values.
If check where datecolumn =convert(datetime,'9999-12-31 23:59:59.000',121) I get the same result as when checking for NULL in the other.
Is there any parameter set somewhere that tell the server to return a value even if NULL is stored in the database?
thank you for reading,

The problem I'm having is described below all this code.---------------------------------------------------------My content page has a SqlDataSource: <asp:SqlDataSource ID="sqlGetUserInfo" runat="server"
ConnectionString="<%$ ConnectionStrings:RemoteNotes_DataConnectionString %>" SelectCommand="SELECT [UserFirstName], [UserLastName] FROM [Users] WHERE ([UserGUID] = @UserGUID)"
onselecting="sqlGetUserInfo_Selecting"> <SelectParameters> <asp:Parameter Name="UserGUID" Type="String" /> </SelectParameters> </asp:SqlDataSource> -----------------------------------------------------Inside my OnSelecting event, I have: protected void sqlGetUserInfo_Selecting(object sender, SqlDataSourceSelectingEventArgs e) { sqlGetUserInfo.SelectParameters["UserGUID"].DefaultValue = Membership.GetUser().ProviderUserKey.ToString(); } ---------------------------------------------------------------------And, inside my Page_Load, the relevant code is: //String strUserFirstName = ((DataView)sqlGetUserInfo.Select(DataSourceSelectArguments.Empty)).Table.Rows[0]["UserFirstName"].ToString();
DataView dvUserDetails = (DataView)sqlGetUserInfo.Select(DataSourceSelectArguments.Empty);
if ((dvUserDetails != null) && (dvUserDetails.Count > 0)) { DataRow drUserInfo = dvUserDetails.Table.Rows[0]; lblHelloMessage.Text = "Hello, " + drUserInfo["UserFirstName"].ToString() + ((drUserInfo["UserLastName"].ToString() == "") ? "" : " " + drUserInfo["UserLastName"].ToString()); } ---------------------Now, here's the problem. My "if" statement is never executing because "dvUserDetails" is null. However, when I break the execution and put awatch on the actual Select() statement, it shows a DataView with the correct return rows! You can see the commented line where I tried tobypass the DataView thing (just as a test), but I get an object reference is null error.The weird thing is that it was working fine one minute, then started getting "funky" (working, then not, then working, then not), and now it just doesn't work at all. All thiswithout me changing one bit of my code because I was checking out some UI flow and stopping and restarting the application. I've tracked downthe temporary files directory the localhost web server runs from, deleted all those files, and cleaned my solution. I've even triedrebooting, and nothing seems to make it work again.My relevant specs are VS2008 9.0.21022.8 RTM on Vista Enterprise x64.

I am update/inserting records threw a web form in vb.net. I need to insert 'NULL' into my microsoft sql server database. I am not talking about the below line of code where website is the name of my paramater. If i do that it will just place a blank into that field in the database. If i dont enter anything into that textbox I want it to to say NULL in that field. So if I go into the actual table in the SQL Server Management Studio and look at the website field of the recored I just added or updated and did not type anything into the web site textbox it needs to say NULL. I also tried the second line of code but that places a single quote in front and behind NULL. So the field will have the value 'NULL'.
website.value = txtwebsite.text.tostirng
if txtwebsite.text ="" then
website.value ="NULL"
end if
The reason why I need the NULL there is because I bind the website filed to a hyperlink template in a gridview. The actual text of the hyperlink is bound to PAYER which is a name of a insurance payer but the navigateto is bound to the website field. If i do not enter any data into the website field and it stays as NULL, then when my gridview is loaded, payers that dont have a website will not be underlined and user wont have the option to click on them since there is no value for the navigateto. But if i use my form to update/add a payer and leave the website textbox blank in puts a blank into that field in my database and when it loads that new row into the gridview the PAYER is underlined and u can click on it but it will just take u to the web site is unavailable page. So is there anyway to actaull have NULL placed into a filed and not just blank space
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)
AND DR.languageid = isnull(@inlanguageid,null)
AND DR.[ID]= @ID
)
go
set ansi_nulls on

hi
I had a view in which I did something like this
isnull(fld,val) as 'alias'
when I assign a value to this in the client (vb 6.0) it works ok in sql2000 but fails in 2005.
When I change the query to fld as 'alias' then it works ok in sql 2005 .
why ?? I still have sql 2000 (8.0) compatability.
Also some queries which are pretty badly written run on sql 2000 but dont run at all in sql 2005 ???
any clues or answers ?? it is some configuration issue ?
Thanks in advance.
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.Â
Is it possible through SSRS designer?
I have a flat file with the following columns
SampleID  Rep_Number  Product  Protein  Fat  Solids
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.
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!!
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.
hi, I have settup up sql mail and did the following:
1. created an E-mail account and configured Out look by creating a pop3 mail profile. tested it by sending and receiving mail, that is ook
2. I Created one domain account for MSsqlserver and Sql Agent service. both services use same account and start automatically in the control panel-services
3. I used the profile that I created in outlook to test the sql mail but got an error:
Error 22030 : A MAPI error ( error number:273) occurred: MapiLogon Ex Failed due to MAPI
Error 273: MAPI Logon Failed
I really do not know what went wrong. I followed the steps from bol and still having a problem. Am I missing something.
I do have a valid email account
I do have a valid domain account
I tested outlook using the email account and it worked. so why sql server does not recognise MAPI.
My next question, How to configure MAPI in Sql server if what I did was wrong.

I am writing a pgm that attaches to a SQL Server database. I have an Add stored procedure and an Update stored procedure. The two are almost identical, except for a couple parameters. However, the Add function works and the Update does not. Can anyone see why? I can't seem to find what the problem is...
This was my test:
Dim cmd As New SqlCommand("pContact_Update", cn)
'Dim cmd As New SqlCommand("pContact_Add", cn)
Try
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add("@UserId", SqlDbType.VarChar).Value = UserId
cmd.Parameters.Add("@FirstName", SqlDbType.VarChar).Value = TextBox1.Text
[...etc more parameters...]
cmd.Parameters.Add("@Id", SqlDbType.VarChar).Value = ContactId
cn.Open()
cmd.ExecuteNonQuery()
Label1.Text = "done"
cn.Close()
Catch ex As Exception
Label1.Text = ex.Message
End Try
When I use the Add procedure, a record is added correctly and I receive the "done" message. When I use the Update procedure, the record is not updated, but I still receive the "done" message.
I have looked at the stored procedures and the syntax is correct according to SQL Server.
Please I would appreciate any advice...

'tblid' table
- Unable to modify table. Â
Cannot insert the value NULL into column 'ValidID', table 'Xe01.dbo.Tmp_tblid'; column does not allow nulls. INSERT fails.
The statement has been terminated.
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 .
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"?
Hello,
I am facing a huge problem in my sql server database using access as a front end.The main problem is trying to execute queries "views" ,since they reside on sql server now,and using variables or parameters in reports and forms to filter on this query.
Ex.
how can the following be implemented using the same query but in sql server?
Access
------
SELECT MAT_Charts.YYYYMM
FROM MAT_Charts
WHERE ((([Area_Code] & "-" & [GROUP_CODE])=[Reports]![MAT_Chart_C1].[MAT_Key]))
GROUP BY MAT_Charts.YYYYMM;
It is specifically this statement in which I am interested:
[GROUP_CODE])=[Reports]![MAT_Chart_C1].[MAT_Key]))
Thank you very much for your concern.
