Hello.
I have a report that can get null as a value for one of his parameters.
I'm running this report in a reportViewer (WinForm application).
How can I send this report the value NULL?
I tried using:
Microsoft.reporting.winforms.reportParameter("p_param",null)
But I got an error that the call is ambiguous becouse it have two overload:
1) Microsoft.reporting.winforms.reportParameter(string,string)
2) Microsoft.reporting.winforms.reportParameter(string,string[])
So how can I send the value NULL?
Thanks.

In a VB.NET script, I am adding the dbnull value to a parameter that will populate a smalldatetime column:
cmd.Parameters.Add("@unitHdApprove", System.DBNull.Value.ToString)
The stored procedure then defines the input as smalldatetime:
@unitHdApprove smalldatetime,
However, the result is that the record is inserted with 1/1/1900 as the date value, instead of <NULL>.
I'm guessing that this occurs because the conversion of a '' to date will return 1/1/1900, and VB requries the parameter value to be a string (at least with this syntax), so System.DBNull.Value.ToString really equals ''.
I've rewritten the proc to accept the date as a string instead, and then for each date, cast it to a smalldatetime or set it to null as is appropriate. But this is a really bulky way to do things with more than a few dates! Is there any way to change what is in my VB code so that the procedure will insert the actual null value?
Thanks,

I am unable to send null values through the Microsoft JDBC 1.1 driver to a stored procedure. Please look at the thread already started on the SQL Server Transact SQL Forum at http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1772215&SiteID=1
View 1 Replies View RelatedHey. 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
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.
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
Key cannot be null. Parameter name: key
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.

I 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

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?
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"?
Thanks in advance...
What I have to do is take orders and generate a report that gives the daily totals of the orders The dates will be on the vertical and the subclass titles on the horizontal: Output
date SO PS Total
1/1/08 5 4 9
1/2/08 3 2 5
1/3/08 5 4 9
mtd 13 10 23
ytd 13 10 23
The SO orders for example can have a diff status each day and I will
need to count this .
1 - how would I pull the orders that I want. I have pulled all credit work orders in but I only want the ones from 2008. Then once I pull them in how do I get the daily info., ie what records fell into the categories for that day. Do I need a loop, cursor, case statement? I also need to count the # of any give group as above. I am new at this and really do not know where to proceed.
see table below
CREATE TABLE #CREDIT_WO (
WO_Noint,
WO_Status varchar (1),
WO_Classvarchar (30),
WO_Subclassvarchar (30),
WO_Create_Datedatetime,
WO_Sch_Datedatetime,

I am having a problem with SqlServer 7.0 sending mail when the sqlserver account is not logged into the machine and mail is open. If I log off of the box and an alert sends mail it just sits in the outbox of the mail client until I log in. Is this the way it is supposed to be or am I doing something wrong. I am using the Inbox as my client.

View 3 Replies View RelatedHi, after some tooling round, googling, hair-pulling etc i have some prototypes of a simple C#.NET 1.1 console app which can now post a message to my yukon SB service i set up. It calls an internal activation stored proc to store the message in a simple table.
The problem i had was in the connection string "... Asynchronous Processing=true". The run-time throws an exception moaning about the Asynchronous Processing=true bit. So i just omitted it completely... Seems to work fine and as expected. I can post a message, my app exits, and the dummy stored proc (which i deliberately made enter a loop updating the table thousands of times to slow it down and lock the table) completed several seconds later proving the asychronousity of it (i issued a "select count(*) from X" query to wait for the write lock to be released, so i knew when the stored proc had finished and released its lock).
So, i guess my question is, firstly what is the "Asynchronous Processing=true" bit for in the connection string if we can just leave it out? And can anyone see any issues with what ive done?

Hi guys,
I've got a query on a particular table returning an odd result:
SELECT DISTINCT WorkStation
FROM Invoice
WHERE WorkStation Is Not Null
ORDER BY WorkStation
This query returns the rows I'd expect plus a null row. This doesn't happen in databases at other sites, or in other tables at this site. The following query behaves as I'd expect returning only non-null AccountNumbers.
SELECT DISTINCT AccountNumber
FROM Suppliers
WHERE AccountNumber Is Not Null
ORDER BY AccountNumber
I can't reproduce these results on another site on a table of the same structure, or on another table at this site.
Any suggestions as to what might be going on?

Is there a way I can return a list of just the ones where NULL is still allowed? I want to update all of the columns with a default value to not allow NULLs.
Dear folks,
