SQL Server :: Inserting Null Value Into Foreign Key Table With Allow Null Enabled?
Oct 2, 2010
I have 2 table Table A, Table B.
Table A - Parent Table
ID - Uniqueidentifier not null(PK)
Table B -Child Table
ID - uniqueidentifier null(FK, TableA)
I have a stored procedure to insert data into Table B, but when I tried to insert a null value into column ID of table B, this error came up:
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.
The statement has been terminated.
The insert statement in asp.net is like so:
sqlcommand.parameter.add(New Sqlparameter("ID", Nothing))
I am guessing adding nothing to the null value column is the problem, but i don't know how to fix it... The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.

This must be a common problem but I haven't been able to find an answer.I have dropdownlist that maps from a SQL foreign key, which can be NULL. Currently, I've added a "Please select..." to the top of my dropdown list and assigned it a value of 0.I know how to map from the drop down list to SQL using a CASE statement in my UpdateCommand.But how to I map from the SELECT statement to my dropdownlist? If this foreign key contains null I get "Item not in Dropdown list". I'd like to show "Please Select..." as the dropdownlist item if the SQL item contains NULL. I saw something online that says to use the value '''' for 'Please select...', but I don't think it's right, plus it doesn't work.Do I have to do something in my SELECT statement or do I have to do something on DDL.Databind?

[URL] I created an AJAX-enabled WCF service to call from a web form. the thing is that after creating it, I'm able to populate my dropdown from the items returned by the service.
but 2 hours later, I get this FireFox error message when loading the page :
"Error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.
Parameter name: element

Line: 2710"
and also this :
Error: ThunderServ is not defined
Source File: http://localhost:50403/ThunderWeb2/Thunder/new_recording.aspx
Line: 105
I delete the service and recreate it with the same code and then it runs fine. but after a while, (1 hour or so), the service isn't defined anymore, I get the error.

I have this table structure, and I can pull ot all I want like product details, color, size and so on. Now I want it to work like this. When I select a color only sizes avalible in that color should be returned from the database, and same thing when I select a size only colors avalible for that size should be returned. NOw it works like price and quantity sets to zero, but it should have been better if it was impossible to choose a combination that don't exists.
Then I have one more. SizeId and ColorId can be null in db. That is not good when I try to receive those rows.

I am trying to create a stored procedure where I can insert null values in columns that have a foreign key constraint and allow nulls. The columns I am trying to insert nulls into are commentid and imageid. I have created an Insert statement in a stored procedure and I get the foreign key constraint error. Can you tell me how to allow inserting data in the other columns without having to insert anything in the commendid and the imageid?
Here is my exec of the stored procedure that is not working:

I have two tables as below.
I tried to establish a relation between two tables in such a way that Table_Contracts will still accept NULL values for [PO_No], but [PO_No] on TableContract will be automatically updated when [PO_No] on Table2_PONo changed. Moreover, if you want to delete a record on Table2_PONo, it needs to be stopped if there is a related data in Table_Contracts.
I set a relation with these parameters:
Check existing data on creation or re-enabling>
No
Enforce for replication>
No
Enforce foreign key constraint>
No
Delete Rule>
No Action
Update Rule>
Cascade
I got this error
Introducing FOREIGN KEY constraint 'FK_Table_Contracts_Table2_PONo' on table 'Table_Contracts' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.

I have a group of radiobuttons. The field they are 'bound' to is of datatype tinyint (sql server), byte .NET. It is set to NOT accept nulls in the database column (col1) and no default value has been set for the column, or indeed, anywhere else.View code as follows:
<ul> <li><%= Html.RadioButton("col1", "1")%></li> <li><%= Html.RadioButton("col1", "2")%></li> <li><%= Html.RadioButton("col1", "3")%></li></ul><%= Html.ValidationMessage("col1", "*") %>
If the user doesn't select any of them, I would expect null to be that the model would attempt to insert into the database. I would therefore get a validation error that I can display to the user, prompting them to choose one of the options.owever, instead of null, the model inserts a 0 into the database. As this does not fail, no error is raised. Can anyone think why? Blowed if I can.I am not setting the default value to 0 anywhere, not in the mvc app or the database

have a form where I insert record via DetailView control. I have some string fields. For each string field (nvarchar in sql) I have defined the Default Value in the SQL SERVER (2008) as ''. Also I have added to each InsertParameter of the DetailsView a DefaultValue="".Yet still, if the user enters no value for one of the string fields, NULL is inserted into the table.

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.

I have a problem with a SessionVariable. I will explain what is happening:
1. From the default.aspx I send Session["LoginByAdmin"] = "Dummy"; and then redirect to this page where I have the code below. So the Page_Load sees that this Session["LoginByAdmin"] != null and enter this page. This works fine !
2. In the Page_Load, I later fill a ListBox1 with foldernames.
3. With Button1_Click1, I will now delete the choosen Folder in the ListBox1 wich works fine the first time and the ListBox updates the new existing folders in the ListBox. (I have wrapped this inside an updatepanel)
The problems comes now when I try to delete a choosen folder in the ListBox1 the second time in a row. When I select a Folder in the ListBox1 and now Press Button1, I will be redirected to "Default.aspx". This meens that this code is running: (That meens that Session["LoginByAdmin"] == null and I have not set this to null anywhere. This is my big question how this variable can be = null here?
if (Session["LoginByAdmin"] == null)
Response.Redirect("Default.aspx");
break;

I've been working on this project which requires me to insert data into a database. Due to the complexities of the function that I am doing, it is more complex to use SqlDataSource and hence I've used the traditional method of inserting to the database. The codes are as follows:
[Code]....
I am not too sure why, but even though I've debugged numerous times and the data gets inserted into the database through the form view, I get this error on the page after everything is executed: Cannot insert the value NULL into column 'reviewDate', table 'ProrsumDB.dbo.Review'; column does not allow nulls. INSERT fails. The statement has been terminated. reviewDate wasn't null when I tried and there are no exception thrown.

In my code behind, I have the following code that I want to insert a null value for a parameter. Instead of doing that, it is adding the word "NULL" to my database. What am I doing wrong?

I have a SQL database. I am getting a datatable from SQL. In SQL Query the table is having null values in the output. But when it is coming to the front end, the null values are replaced by empty values.
So in the front end in the datatable i am having empty values in some cells. I am trying to insert this datatable into access. For this i am using following code...
OleAdpData.InsertCommand.Connection = OleConn; // OleConn is the OleDbConnection
OleAdpData.InsertCommand.Connection.Open();
OleAdpData.Update(dtData); // dtData is the datatable
OleAdpData.InsertCommand.Connection.Close();
It is inserting the datatable to access database. But it is inserting the empty spaces as present in the datatable. I want to insert NULL into the cells in access datatable where the cells are empty. Where should i add my logic for this.
