Problem With Adding A Date Field To A Database When It Is Null
Jun 21, 2005I am having problems adding a date field to a SQL Server Database from a form in ASP.Net. When I leave the date field blank, it automatically inserts Monday, January 01, 1900. I want it to be null when the expiration date is left blank. Can someone please help me with this?

Passing NULL Value Not Working
Oct 24, 2007I 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

Passing NULL-value Into Package Variables

What's the correct syntax for passing null-values? But maybe (because i cannot find anything on this) i should ask if this is even possible...
Passing NULL To DataSet Parmameter
Apr 13, 2007Hey All,
I have a number Stored Procs that have been around for a while that pull the entire list, or if I pass an ID, will just the record for that ID like below.
I want to be able to use these querries to poplate Multi-Select parameter dropdowns. going to the Data tab and creating a new dataset, I put in the SP name, and close the window. I then go to the Red ! point to preview the data it prompts me for my ID parmaeter on my SP. In the dropdown list it has '<Null>' (no ' though). When I run it, it works fine and returns all of my records.
When I run the report, it errors saying I didn't pass a parm for ID. I go back to the data tab, and edit my DataSet hitting the elipse. I go to the 3 tab called parameters, and type the following I get the following errors:
@ID = <Null> ---- ERROR - [BC30201] Expression expected
@ID= ---- ERROR - Return statement in function must return a value
@ID = Null -----ERROR - Null constant not supported use System.DBNull instead
@ID = System.DBNull ----ERROR - [BCS30691] DBNull is a type in System and cannot be used in an expression
@ID=System.DBNull.Value --- NO ERROR, but it does not return anything either. I also did a SQL Trace, and I can see that it doesn't even send the querry to the database.
Does anyone know another magic value I can pass to get this to work?
I am being a little stuborn, I know that I could just create new procs, and wrap up the null, but the more stuff you create the more you have to maintain, so I would prefer to reuse these.
Thanks in advance.

PS: My company is moving from crystal reports to Reporting service, and Reporting services is Rocks! It is very intuitve, simple and straign forward. The formatting is easy with the table and the matrix control blows away the crosstab control in crystal. Also, I'm finding that because crystal was so un extendable, that I would spend hours shaping sql to get over it's blemishes, and hours shaping it in the report, only to sometimes reliaze that the proposed onetime hack wouldn't work, and have to start all over! So far with RSS any tips and tricks I have learned can very easily be applied to any report I work on! Aslo, I do mostly interanet web apps, and it is nice to dump my reports on the Report Server, and not worry about haing to create a web page, create a datasource and all the ansilary stuff to go along with it. The only thing I don't like is the name 'Roporting Services': It does not stick out too far in Google Searches like 'AJAX.NET' or 'ASP.NET'. Anyway kudoes to the Reporting Services team!

Aug 29, 2006Version: ASP.Net 2.0Language: C#Hello Everyone!I'm saving data from a function to an SQL Server 2000 db via a stored procedure. There are a few fields which are conditional and thus need not be passed to the procedure everytime. Under those circumstances I need to store null values in the fields.The problem is if I the value of the parameter as null, VS throws the error that a required parameter is not passed. I tried setting 'IsNullable' property of the parameter to true but it works for only those fields who are declared NULL in the stored procedure (For e.g. @DOB DATETIME = NULL).Strangely, this works well in classic ASP.Does anyone know how to accomplish this? Note, altering stored procedures is not an option for me.Thanks a lot!
View 4 Replies View RelatedDNN DAL SqlDataProvider Passing NULL To SQL Stored Procedure
Jun 1, 2006Hello,I'm trying to pass a null object to a stored procedure to update a SQL Table boolean field with a null value. My SQL Table boolean column allows nulls.I'm using an InfoObject which has several properties all corresponding to fields in the SQL Table. One of those fields is a boolean. I create an instance of the InfoObject in my code and assigns values to the various properties. The boolean property in question (call it InfoOjbect.BooleanProperty) is not assigned anything. I then call my StoredProcedure passing the InfoObject to it (using the DotNetNuke DAL architecture) and the final result is the Table's boolean column is populated with a 0 and not a NULL. If I explicitly define the InfoObject.BooleanProperty = null.nullboolean before passing it to the Stored Procedure, the same thing happens. How do I pass a null to the SQL database for a boolean field? I've tried making InfoObject.BooleanProperty = dbnull.value but it won't let me do this saying "dbnull cannot be converted to a boolean." Do I have to explicitly create my InfoObject properties to allow for a null to be assigned to it?Any help would be greatly appreciated. I'm using the DotNetNuke DAL architecture passing my InfoObject through a dataprovider to the sqldataprovider which calls the SQL Stored Procedure to add the new record to the Table.Thanks in advance for any help.

Dec 19, 2007Hi,
I'm not sure if this question should be in this thread but anyway...
I have a form (Mricosoft Access front end) in which the user enter a Pending Date in one of the fields. The date is populated into my backend (SQL Server) withouht problems.
Whenever the issue which had the pending date in the field is resolved I'd like to delete this date from this field and also from the back end. At the moment I'm not being able to pass the "value" Null to my back end (probably because it's a datetime type). I've searched the net throughout and I couldn't find a way around it. Only found solution to when the data is not date but numbers/letters, etc... Any ideas on how can I sort this out?

Passing Null To Stored Procedure In Reporting Services
Jun 27, 2007Hello,
I have a report. I need to make a drop-down parameter optional. I've setup the parameter to use a dataset as its source, and I need to allow the value to be null. I've selected allow nulls check box, and I've even tried setting the default value to System.DBNull.Value. But, when the entry is not selected (blank), no data ever comes back. If the data is blank or null, my procedure works (I've tested it). How do I send a null value to the database through reporting services report? I was hoping to avoid creating a special query just for that purpose.
Thanks.
Passing Null Value Parameter To A Data-driven Subscription
Jun 13, 2007I have a data-driven subscription (DDS) stored procedure that gets called when a subscription fires and returns parameters to a report. One of the parameter values I want to return is NULL, which also happens to be the default value of the corresponding report parameter.
When I set the report parameter to use the default value (NULL) when setting up the subscription in Report Manager, the subscription works fine. When I try to pass the NULL value from the DDS proc to the report, the subscription fails.
I do not know what the error logs say. I've rarely looked at them and what I have seen seems a bit cryptic. I've narrowed down through trial-and-error that passing the NULL value is the issue.
Has anyone else experienced this issue and do you have a resolution?
Thanks in advance for your assistance.

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 .
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"?

Passing Date Parameter To Oracle Query
Aug 16, 2006ActivityDate is a report parameter set up as a date that I'm trying to pass into an Oracle query. The specific WHERE clause is
WHERE PROJ_DATE = TO_DATE(:ActivityDate,'YYYY-MM-DD')
When I run the query from the Data tab, all works as expected. I suspect the reason is that I under the date as 2005-12-31. If I enter the date as 12/31/05, the query fails ("Not a valid month") unless I change to function's format to 'MM/DD/YYYY' in which case I, again, get good results.
But when I run the report from Preview, I get no results at all no matter what format I use in the function.
Any chance any of you have seen this and know how to work with it?
Stored Procedure - Passing Date Parameters Failed
Aug 4, 2015I am working on an Excel VBA report which is linked to an SQL Server database. The front end is Excel VBA routine, the backend is SQL Server stored procedure.
The VBA routine passes 2 dates to the stored procedure but it seems that it doesn't accept them.
The 2 date parameters in the stored procedure are @OrderDateRangeStart and @OrderDateRangeEnd.
Here is a portion of the stored procedure:
alter proc uspSalesCommission
...
...
@IncludeOrderDateAsCriterion int,
@OrderDateRangeStart date,
@OrderDateRangeEnd date
as
BEGIN
...
...
WHERE (@IncludeSalesPersonsAsCriterion=0 or Staff.name in (@Salespersons)) and
(@IncludeOrderDateAsCriterion=0 or SALESORD_HDR.ORDERDATE between @OrderDateRangeStart and @OrderDateRangeEnd)
In Excel VBA, the code passing the parameters are:
cmd1.parameters("@OrderDateRangeStart").value = cdate(me.startDate)
cmd1.parameters("@OrderDateRangeEnd").value = cdate(me.EndDate)
where cmd1 is a command object, me.startdate is start date field in Excel me.enddate is the end date field in Excel.
The Excel VBA routine works only when the day and month are both 1,(e.g. 1/1/2015), when they are other values (e.g. 31/5/2014) , it failed.

Drill Through Report -- Passing Date Parameters -- Resulting In RsReportParameterTypeMismatch
Jul 4, 2007All,
I have two reports. One is the main/summary report and other one is drill through. When I pass the Start and End Date parameters from main to the drill, the original format of DateTime changes. For example, in main report the data is displayed for following date range:
4/7/2007 - 5/9/2007 (i.e 4 July 2007 to 5 Sept 2007)
which displays correct data.
However, when I click on the drill through link, it jumps to the drill through report but displays data for the following period:
7/4/2007 - 9/5/2007 (i.e. 7 Apr 2007 to 9 May 2007)
The reporting services is converting the value from one format to another of the report parameters when passing them from parent report to the drill through. When run individually, these two reports display data for correct date range. And you can imagine, the child report crashes with rsReportParameterTypeMismatch error if the start or end date had a day part greater than 12 (e.g 25/4/2007).
I can't understand what could be going wrong. All the parameters in both reports are datetime, so intrisically, it shouldn't matter even if the reporting services is converting or using different date formats as long as the data type remains the same. Is there a way to fix this and force the parameters to stay in the format they are provided in the main report?
Your help is much appreciated.
Thanks.

Doing A 'between' On A NULL In A Date Field
Mar 29, 2007Hi everyone,
I have two tables - caseinfo and steps.
Caseinfo shows when a particular case entered and exited a particular project. If the project hasn't ended yet, then the end date is NULL.
Steps shows the steps the case has gone through and the dates of those particular steps.
I need to join the tables to show the steps the case went through during a particular project, but I'm having trouble with the NULL values in the end dates.
If I join the tables so that the step date is between the start and end dates of the project, then I get no step information for the cases where the end date is NULL (that is, where the project hasn't ended yet).
Does anybody have any ideas?
Here are my tables, the query that shows the main idea (with the wrong result), and my expected results.
