Null Default Value on Control Parameter.
Greetings! I am working with a gridView that plugs into a sqlDataSource which executes a stored procedure that has 3 parameters. I would like to set two of the parameters to a value and have the third default to a null value. I have tried the following code: <asp:SqlDataSource ID="sqldsJobs" runat="server"
ConnectionString="<%$ ConnectionStrings:ExampleConnString %>"
<asp:Parameter DefaultValue="813" Name="CompanyID" Type="Int32" />
<asp:Paramet...context.SubmitChanges() fails for null values (which are set to NOT NULL but have default values)
the topic pretty much says it all.I have a table with a column of type varchar(5). It's defined as NOT NULL and a default value of let's say "test".Now whenever I try to insert a new row into that column and I do not define the column mentioned above - the value for that column is "null". This of course leads to an exception.I do not want to insert null or Dbnull.Value or whatever.. I don't want to insert anything at all in that column so that the database can insert the default value.How am I supposed to do that? I do need that column later in my program so d...SQL QUERY replace NULL value in a row with a value from the previous known value
I have a table with no unique ID, I created an Id with ROW_NUMBER ()
OVER (ORDER BY column asc) rank
and created a stored procedure with the rank and table.
In this stored procedure I want to create an extra column that checks
if the value from another columns contains value = 100
2313,'6497269','001' ,412 , NULL
2314,'6497269','002' ,413 , NULL
2315,'6497269','003' ,100 , yes
2316,'6497269','004' ,430 ,NULL
...Gridview control replaces a NULL value in SQL with
I have a Gridview control that I am using to display information. In the RowDataBound() I am retreiving data from SQL to use; however, if my varchar() field in SQL is NULL, then the GridView is telling me that the value is " ".
Has anyone seen this, and if so, how can I get the value to be blank. I have already tried re-defining my SQL query to replace the NULL value with an empty string; however, even with the empty string, the GridView is replacing it with " ".
If anyone has any insight it'd greatly be appreciated because I am out of ideas.
T...Testing for NULL return values in test scripts
I was wondering if there is a way to use the ok() function in Test.pm
to check for a null return value. It looks like the 3 arg form of ok()
I'm using only tests the first 2 args to see if they're equal.
I'm considering this approach:
$val =3D some_func(); # returns NULL on failure
if($val !=3D 0 && $val ne "0")
$isnull =3D 0;
$isnull =3D 1;

I'm not sure if this is a .asp issue or a SQL issue..... i've created a form on a .asp page in dreamweaver.. all fields point to the correct dataset, etc... instead of adding a field for the "date entered" , I've put a getdate() data value in the SQL Express 2005 database field.. so, theoretically, when I submit the form to the database, SQL will fill in this date entered field automatically with the current date/time stamp... but, when I submit the form, I get a message on the web page similar to this:

Can someone explain to me the difference between say, Dropdownlist.SelectedItem.Value and Dropdownlist.SelectedValue??
Just curious, Thanks!Tim
These are going to return the same thing. dropdownlist.selectedvalue is a shortcut to get the currently selected value in the dropdown. If that is all you want then you can just use that. If you want to access the currently selected item you can use dropdownlist.selecteditem and that return the item and you can then access any of the item's properties, including in this case the value property.

I m able to change the values of the various columns which have non null values.

Any idea how to resolve this?RAJAT

Hello,I'm a beginner in SQL and I have been searching through the SQL Cookbook and Google but I can't seem to find an example of what I want to do.

I am tearing my (remaining) hair out here, trying to test for a NULL value from the database.
I am using SQL Server 2000, with Visual Web Developer 2005 Express (language VB). My database design uses Guids (uniqueidentifiers to SQL) to key and relate records. My application architecture has a Data Access Layer with Tableadaptors for most tables.

In a workflow, I have a Mapping activity that gets a value from NDS and
sets it to a variable, with the source expression being
IDVault.get(recipient, 'user', 'val1') and the target expression of
flowdata.var1. The value val1 in NDS may or may not be valued (usually
not), so I want to do certain things in the workflow only if the field
has a value.
Next there is a Condition statement that evaluates the variable to see
if it is null (flowdata.get('var1')!= null). The problem is, whether or
not the field existed, the condition statemen...Testing for Null value
I seem to have a problem testing for null values in a SortedList. I want to assign them to text boxes on a web form, but if I assign a null value to a text box it throws an exception. If I try to test for a null value in the sorted list I get an exception.
Here's some sample code that doesn't work, and I don't understand why. All I wanna do is test for a null value without generating an exception!
