How can I fix this? When I do the below I get the error message:
"Cannot insert explict value for identity column in table
'Employees' when IDENTITY_INSERT is set to OFF."
To get this message, I click the Add button to add a new row to the
database, and then I click the Update button to save the new database
to the external memory.
The methods I used are below.
Thanks,
Chris Lusardi
Private Sub btnAdd_Click(By Val sender As System.Object, ByVal e As
System.EventArg s) Handles btnAdd.Click
Dim drNew As DataRow
drNew = dsAdoSbs.Employ ees.NewRow()
drNew.Item("Fir stName") = "New First"
drNew.Item("Las tName") = "New Last"
dsAdoSbs.Employ ees.Rows.Add(dr New)
End Sub
Private Sub btnUpdate_Click (ByVal sender As System.Object, ByVal e
As System.EventArg s) Handles btnUpdate.Click
daEmployees.Upd ate(dsAdoSbs.Em ployees)
UpdateDisplay()
End Sub 6 6668
When I look at the properties of the data adapter for daEmployees
nothing jumps out at me?

Christopher,
I would look in the database for the description of the key column
Just my thought,

How do I do this? When I start vb and view "Server Explorer", I see:
- Data Connections
- chrislusardi\sq lexpress.AdoSte pByStep.dbo
+ Database Diagrams
- Tables
- Employees
LastName
FirstName
...
I can't find "sqlexpress.Ado StepByStep" on my PC with a search on the C
drive.

With a I double click on Employees, I see a yellow light bulb next to a
column indicating it's the primary key column. When I click on that
yellow bulb, nothing in the properties jump out and say here's the

Christopher,
Can you download the SQLServer Express beta management tool. I have no
expirience with that but it is for sure better than the server explorer.

I would modify your data adapter to ensure the identity column is not part of
your insert statement.
The button click event is adding a row to your dataset, not the database.
So calling the 'Update' method is actually doing an insert (not an update) on
the row you added.

Hello,
How do I get SQL server 2000 to continue the sequence of identity
column values after I perform an insert into the table with the set
identity_insert <table name> on statement? Eg if I insert values into
the identity column with values 1-999, how do I get the next number to
be 1000? Can the identity seed value be changed if there are records in
the table? Can the identity seed value be re-set to start again from 1?
Thanks
Isaac

Greetings,
I'm having a very strange problem in an AC97 MDB with ODBC Linked tables
to SQL Server 7. The table has an Identity field and a Timestamp field.
The problem is that when a new record is entered, either from a form or
from the table view of the table, when the record gets saved it
immediately displays #DELETED# in all of the fields. However, if I close
the form or table view and reopen the record has in fact been inserted.

Hi All.
I'm trying to insert data into 2 tables (parent-child) using the ADO.NET's
SetParentRow method. The parent table has an identity column as primary key.
When I execute the code below I get the following message: "Cannot insert
the value NULL into column 'hdtID', table
'myinstance.mydb.Hotel_Details_Lang'; column does not allow nulls. INSERT
fails." Any idea?
PS: To create the DataAdapters, I'm using SqlCommandBuilder.
