i have created a web form, where i have 3 textboxes into a table and one submit button.
i would like to store values from the textboxes into my database (sql server) when i click the submit button.
but how to insert the value that is not in textbox into database which is primary key for table without identity column.
I am working on a web app for an online photo album. It is the last project in Scott Mitchell's book: "ASP.Net 2.0 in 24 hours".
I am creating a page where users can enter new photo images. The functionality for uploading an image will come later. I am working on just inserting a new row into the Pictures table with an optional category, a required title and a required description.
I am getting an error when I try to insert a new row.
Here is a screenshot of the page with a shot of the dropdown list.
The Categories are user-specific. I am getting the correct values retrieved.

There are two pretty simple database tables involved here.
NOTE: The CategoryID and PIctureID are both autoincrement integer columns.
[URL]
The page uses a DetailsView that uses a SqlDataSource that uses the Pictures table. (The DetailsView's Default Mode property is set to "Insert". The "Enable Inserting" checkbox is also checked.)
The dropdown list uses a dropdown control that uses a SqlDataSource that uses the Categories table.
When the "Insert" button is clicked the CategoryID value associated with selected (Category) Name on the dropdown list will be used along with the Title and Description values to insert a row in to the Pictures table. (If no Category value is selected, then a null value will be used for the CategoryID. This is OK because the CategoryID column in the Pictures table allows nulls.)
My problem is that I am getting this error:
Cannot insert explicit value for identity column in table 'Pictures' when IDENTITY_INSERT is set to OFF.
(FYI: I have the full version of both Visual Studio and SQL Server.)
Here is my source code for the page:

Following the MVC1 vers of Nerddinner, but using 2010 and MVC2. Never seen this error. Looked in controller, model, view. Where does MVC pass the identity value, and how to stop it? I have never had to set IDENTITY_INSERT in any app before.

How to handle this error
"An explicit value for the identity column in table 'UserActivation' can only be specified when a column list is used and IDENTITY_INSERT is ON."
How should i insert null values into a database. I have textbox1 and the textbox2 will convert the value out of textbox1, when i the time i click save and the textbox1 is empty i got an error, "Conversion from string "" to type 'Date' is not valid." i just want to insert null value if the textbox is empty.
View 1 RepliesI need to insert multiple records using a script.
My table is
Region
(
ID int,
Name varchar(50),
Description varchar(51)
)
One thing I can use is to retrieve the max(ID) from region and store it in a variable and increment the variable sequentially and insert. But, if any other user inserts a record while I am executing this script then max(id) might clash with the id inserted with other user causing my script to fail.
Is there any other option to insert record sequentially base on the highest number in the table.
I have an insert table with identity specification set. And I getthis error. I'm using a stored procedure to store it. How do I correct it. I'm also using a details view on my insert page.

I am sure this has been covered many times but I can not find what I am looking for and I am sure it is simple.
I am trying to insert into an access database table a date taken from a calendar control or a textbox that the calendar control writes to.
Currently I am getting a "datatype Mismatch" error.
The wierd thing is this was working fine and then it just started throwing this error,

I have tables:
MAILBOX
MailboxId int PK
MailboxTypeId int FK
MAILBOXTYPES
MailboxTypeId int PK
I can't make relationship between MailboxTypeId in table MAILBOXTYPES and MailboxTypeId in table MAILBOX why ?
tbl_table1
ID primarykey (autoinc)
UserId uniqueidentifier
IdNumber primarykey int
I'd like to have a relationship between two tables.
I am needing to search the primary key column in my database and when I set the where statement in the datasource as Where
="it.TRANSACTION_ID
LIKE '%' + @SearchID + '%'"
It tells me LIKE must be of string type. What can I do?
I have a database table and the column that has identity specification set to true is not displaying in numerical order. Whether I use Server Explorer and use Show Table Data or I create an application to view the contents of the table using a DataGridView I see that column displayed with the numbers often though not always in a non-numerical order.
Does it perhaps have to do with the way the rows for that column were added or would it be something else. I was looking at the properties for that column but don't see what I would change to make the rows display in numeric order.
I want to retrieve identity column value after running Insert or Update (using Access DB in C#). How can I do it?
i use a Typed dataset to fill and update...
In the tutorial I am doing I have been requested to change a field in the colums properties of a table. The ID column is currentl displaying NO and NO again for "is aIdentity. I can Highlight the values but cannot change to yes. either in the properties talbe or in the properties window on the right hand side of IDE interface. How do I change that value?

View 2 RepliesThere is one table which primary key is ID and its data type is Integer with auto increment. Gradually the value has increased and I want to change it to hold large amount of value.
So, Which in data type I have to change from Integer without effecting the previous values?

I am where you "Create" an entry in the table, i have deleted the Id field, as Id is my primary key, and Is Identity = Yes, Identity Increment = 1, Identity Seed = 1.
When i hit the create button, the Id value is being validated, giving an invalid error. If i add the Id column back to the page, and fill in any number and click create, the entry is added to the database, with the Id value incremented (the typed in value does not matter). I believe this must have to do with the Movies.Designer.cs... but not sure how to fix it. Id should not be validated as it auto-incraments, but the model is looking for a Id value..
I am developing a asp.net application and i am using SQL Server 2008. I took a IDENTITY column as Record_ID for detail table where i will have trillions of records per year. So just want to ask whats the largest number record id (identity) column can hold and in ASP.NET which data type i should use to handle record id as i am using this id as a reference to update the table data. I don't want to end up being trapped some day.
