Problem With Insert , Cannot Insert NULL Value
Jan 30, 2007
Good evening,
I have created a table like this:
create table Teacher(tid integer,
fname varchar(20),
lname varchar(30),
primary key(tid));
Well i insert many Teachers uning : insert into values ... etc.
These inserts are being placed in an sql file named insert.sql.
All the insertions are fine.
Now I'm trying to insert another teacher using another file e.g. my_insert.sql and it says cannot insert NULL into teacher tid etc.
Why does this happen,in my my_insert.sql file all the filds of the tid are filled with non null values?
What's going wrong?
Thanks, in advance!

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 am getting this error: "Cannot insert the value NULL into column 'OrderID', table 'outman.outman.Contact'; column does not allow nulls. INSERT fails." -- But my value is not null. I did a response.write on it and it show the value. Of course, it would be nice if I could do a breakpoint but that doesn't seem to be working. I'll attach a couple of images below of my code, the error, and the breakpoint error.

Dear All,
I am populating some new tables from old tables, after I did some re-structuring to the database.
I have created a table with langID and langCode.
I also created a temptable, with the data being captured from an old table. The fields that are the most relevant at the moment are lid, and fk_langid.
In the old table, lid, has strings in it, for example en, fr, bg etc, and fk_langId will be the foreign key to the new table.
Now my problem is that there are some lid's which do not exist in the new table, and as so I need to hardcode an id for them in the new table.
So I was doing something like this:-
update #tempTable
SET fk_langid =
(
SELECT lid,
CASE
WHEN lid like '%sr%' THEN '1234'
END
FROM #tempTable
)
But I am getting an error:-
Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.
Can you help me out on how I can update the fk_langid in the temptable

I have a small form where a user can give comments if they wish, but the comments are not required. If a person doesn't enter comments and I enter the form data into my database, it will insert NULL.
Is there a way that I can insert just blank text instead of NULL?

Using SSCE 3.5 beta 2, I am loading a CSV file into a SqlCeUpdatableRecord using VB Net. The parsed contents of the CSV have three data types which are being set in the record using SetInt32, SetString and SetFloat. How can I insert a NULL value in the Int32, String and Float data type fields? A VB Net or C# example would be appreciated.
The .sdf database was created specifying NULLable fields.

I've 2 tables with a relation:
Customers
- CustId
- Name
- LevelId ==> FK relation to Levels.LevelId
Levels
- LevelId
- Description
What I want to do, is save a NULL value in the Customers.LevelId when no level is selected. I'm using C#, a CLR StoredProcedure and the DbType.Int32 for that column. When I try to save a null value, it says "cannot convert null to int", what is clear. But in the database it is possible to save a NULL value.
The question is: How to save a null value in a int column via a C# CLR Stored Procedure?

Good Afternoon,
I'm using the personal website starter kit. I would like to add tags to my photos so I've added a Tags table (identity, tagDesc) and an intersection table PhotoTags (PhotoID,TagID). I pass a set of tags as a comma deliminated string such as (Home, Family). The procedure below (sorry I'm not a TSQL programmer) errors out with the message "Cannot insert null into TagDesc" or something like that.

END
IF (NOT EXISTS(SELECT TagID FROM Tags WHERE LOWER(TagDesc) = LOWER(@Tag)))
BEGIN
INSERT INTO Tags (TagDesc) VALUES (@Tag)
SET @TagID = SCOPE_IDENTITY()
END
ELSE
SELECT @TagID = TagID FROM Tags WHERE LOWER(TagDesc) = LOWER(@Tag)
--finally insert into the intersection table
INSERT INTO [PhotoTags] (
[PhotoID],
[TagID]
)
VALUES (
@Photoid,
@TagID
)
END
COMMIT TRAN

hi all!I have a task, for example, to create a record for bill. I have table which represents this bill entity (Bill_ID, Amount, CreationDate, ExposureDate, PaymentDate)In table definition date fields allow null. I would like to create bill, which means insert record: (new_bill_id, 1000, 2007.12.11, null, null) But it couses exception. Smth like: System.Data.SqlTypes.SqlTypeException, date should be not null. How could I do it?Please advice!

Hi:
Trying to insert null value into sql table, but not working, if I use:
if (strMyText.Length == 0) command.Parameters.Add("@Text", DBNull.Value); // or using:("@Text", null), or using:("@Text", DBNull) else command.Parameters.AddWithValue("@Text", strMyText);
When I go back to table, I see the value is: 'NULL', has single quotation mark, suppose to be: NULL
Where is the problem?
Thanks a lot.
Jt

Hello,
I'm working on a website that allows users to upload small JPEG files. I followed the article at http://aspnet.4guysfromrolla.com/articles/120606-1.aspx. On the webpage I'm using a formview control to insert new records in the database. As suggested in the article I removed the "type='object'" from the insert parameters for the image column. The data is saved by using a sqldatasource with stored procedures. The image column is of type varbinary(max) and allows null values. Everythings works fine as long as the user uploads an image. The data is saved correctly and on another page the image can be viewed. However if the user does not upload a picture and tries to save the new record the following error is thrown:
�Implicit conversion from data type nvarchar to varbinary(max) is not allowed. Use the CONVERT function to run this query.�
In the formviews iteminserting event I have the following code: Dim imageBytes(fileupload1.PostedFile.InputStream.Length) As Byte fileupload1.PostedFile.InputStream.Read(imageBytes, 0, imageBytes.Length) e.Values("Image") = imageBytes What code should I use in case the fileupload1 has no file? I tried something like: e.values("Image") = dbnull.value But that doesn't work. Any suggestions?

I am trying to insert a record to based on the source below, however the GUID of GiftOcc_ID is being returned as zero's so the first record can be added but as it is defined as the primary Key and uniqueidentifier the next record fails with a duplicate entry. Basically how do I ensure that the GUID is created and not nulls. As you can see I am trying to use Newid() which I have inserted as a default value but that does not work. Also as it is a unique identifier the "is identity" is not available
Protected Sub CreateGiftOccasion(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
Try
Dim null As New Nullable(Of Integer)
Dim da As New DataSet2TableAdapters.Gift_OccasionTableAdapter
Dim GiftOcc_ID As Guid
da.Insert(newid(), Occ_Type_Text.Text, Occ_Desc_Text.Text, Calendar1.SelectedDate, Calendar2.SelectedDate, 1)
Catch ex As Exception
Response.Write("Ooops")
End Try
End Sub
The code from the table adapter regarding inserts is:
<InsertCommand>
<DbCommand CommandType="Text" ModifiedByUser="False">
<CommandText>INSERT INTO [dbo].[Gift_Occasion] ([GO_ID], [Go_Type], [GO_Description], [GO_DateOn], [GO_DateOff], [GO_Active]) VALUES (@GO_ID, @Go_Type, @GO_Description, @GO_DateOn, @GO_DateOff, @GO_Active);
SELECT GO_ID, Go_Type, GO_Description, GO_DateOn, GO_DateOff, GO_Active FROM Gift_Occasion WHERE (GO_ID = @GO_ID)</CommandText>
<Parameters>
<Parameter AllowDbNull="False" AutogeneratedName="" DataSourceName="" DbType="Guid" Direction="Input" ParameterName="@GO_ID" Precision="0" ProviderType="UniqueIdentifier" Scale="0" Size="0" SourceColumn="GO_ID" SourceColumnNullMapping="False" SourceVersion="Current">

</Parameter>
<Parameter AllowDbNull="True" AutogeneratedName="" DataSourceName="" DbType="AnsiString" Direction="Input" ParameterName="@GO_Active" Precision="0" ProviderType="VarChar" Scale="0" Size="0" SourceColumn="GO_Active" SourceColumnNullMapping="False" SourceVersion="Current">
</Parameter>
</Parameters>
</DbCommand>
</InsertCommand>
Many thanks in advance for any assistance

Hi I'm using DetailView and I have a text box which show the date. I have formated the date as shortDate {0:d} format. I want to insert/update null if that text box is empty.
I have tried putting null value in my Update statement in sqlDataSource. And I'm getting error saying can't convert varchar to smalldatetime.
If I don't set null value as above, some large date (01/01/2033) has been inserted in my database.
Can anyone help me?
Moe
