Insert Identity Value With SqlCeResultSet
Aug 20, 2007
Hi
I have a table with an identity column. This is set to increase by 1 and start on 1, and is the first column of the table.
When I insert a record into the resultset, I get an error stating that it can't be DbNull.
Th record is created from a resultset with the query "Select * from table", so the id should be included
But as I understand it, it should be increasing automatically, right? Becuase that's the behaviour of the normal sql Insert command. I have seen an article that just left the id column in the record alone before inserting it, but it didn't help me.
How can I sidestep this issue?

While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,

I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?

Hello,
I'm just learning SSIS and I've hit my first bump. I am doing a bulk import from a tab delimited text file to an empty sql table that has a Idendity column defined. How do I tell the bulk insert task to skip that column when inserting from the text file. If I remove the identity column it imports the data fine, but I want to create the indentity column in the table too.
Thanks.

Let me start off by saying I have posted this on:
comp.databases.ms-sqlserver
My apologies, try not to do that again.
I have a table that I am trying to insert into with data from another
table. Here is that Query:
INSERT INTO item (identifier, name, customlgtxt1, weight,mainprice,
customnumber3, customnumber4)
Select partno, name, description, weight,price, qtyprice, qty
From Import2
This seems to work fine.
My dilemma has to do with an 'id' column in that item table. This is
incrementally updated by one..ie Natural Key. I have set it to
Identity and used Set @@IDENTITY AS 'id'...worked like a charm. But
for reasons that have to do with a front end admin tool used by the
home office I can't set this column to have an Indentity property.
Screws up the insert done with the admin tool.
This is a item/price database by the way. Name of item, price,
description, qty price..etc.
So I've tried to put this trigger on the item table
CREATE TRIGGER auto_fill ON [dbo].[item]
FOR INSERT, UPDATE
AS
BEGIN
declare @maxc int
set @maxc = (select Max(id) from item)
set @maxc = @maxc +1
Select 'id' AS '@maxc',
notorderable = '0',
createdon = getdate(),
createdat = getdate(),
createdby = 'Steve',
modifiedon = getdate(),
modifiedat= getdate(),
modifiedby = 'Steve'
END
But the Insert Into statement (see above) will not work...giving the
error
"Cannot insert the value NULL into column 'id', table
'new_Catalog1v1.dbo.item"
Which I know...that's why I set it to Identity..but that cannot be.
So the question is how to set an autonumber (or natural key or I'm not
sure of the name) that updated from the max(id)table when inserting from another table.
And then...one more.
I have to update a table named UNIQUEIDS with the lastest value of the
id column (max(ID))..UNIQUEIDS keeps track of the latest value inserted
into the id column for a number of tables. Here is another trigger I
put on the item table to update the UNIQUEIDS table.
create trigger upUniqueIds_item on [dbo].[item]
for update,Insert, delete
as
begin
Select @@Identity as 'id' from inserted
Update uniqueids
set id = @@identity
Where tablename = 'item'
End
But of course this doesn't work if I can't set the columns to
IDENTITY.
I hope someone can help and I hope my explanation had made sense.
Need to increment the id field using max(id) and update another table with the last imported value of max(id). One occurs during insert..another after the insert..i think?

I am currently working with typed sqlceresultsets. I noticed that each resultset manages its own databaseconnection. I am considering to change this to a situation where I can reuse a databaseconnection on more than one sqlresultset.
Will this result in better performance? for example, when I have 2 updates for wicht I need 2 resultsets, wouldn't it be better to use 1 connection and transaction instead of each resultset creating/disposing its own? I would realy like to hear some oppinions. thanks!

Hi,
I have an updateable sqlceresultset, which i use to bind to a datagrid. The user can modify values in the grid. I wish to update these values in the database only when the user has finished making these changes and clicks "Accept" button. But with the sqlceresultset, it looks like with every modification in the grid, the resultset is updated and change is written to the sdf database file . Please suggest how to work around this.
Thanks

Hi I have written an Windows Mobile Application that insert 1000 records on SQL Compact 3.1 but I am having performance issues. If I use SqlCeResultSet and SqlCeUpdatableRecord in C# tha insert take 7 seconds to complete. But if I write a C++ application that uses OLEDB it takes only 4 seconds.
How can I improve the performance of the C# application? Also I would like to know if there is any possibility to use the same OLEDB objects that I use in C++ in a C# application.
Thanks a lot

I have created my connection correctly
if (_deviceConn.State == ConnectionState.Closed)
_deviceConn.Open();
_deviceCMD = new SqlCeCommand("UPDATE metar SET observation='"+ Value1 +"',lastupdate='"+ Value2 +"',Valid_Time='"+ Value3+"' WHERE aerodrome_oaci_code='"+ FilterValue +"'", _deviceConn);
int RecordsAffected = _deviceCMD.ExecuteNonQuery();
The code executes fine, in fact the recordsaffected returns 1, but Nothing happend on database side. Another thing is, when i run the project on release mode, a copy of the SDF file is there, so, which of the sdf files the project is actually updating?, cause im querying both (the one in my project source path and the one copied to release folder) and both have the same data witout any modification.
My Copy to output directory setting is = Copy if newer.
If i try this with query analizer works just fine.
Any ideas?

I have 2 tables - tblOrders and tblOrderDetails. Every time an order is placed, 2 INSERT statements are executed. The first one enters the general order and customer information in the tblOrders table:INSERT INTO tblOrders (custname, custdetails, orderdate) VALUES (@custname, @custdetails, @orderdate)The primary key in this table is OrderID which is an Identity column. This is the foreign key in the tblOrderDetails table.I'm trying to get the Identity value from the first INSERT statement to use in the second INSERT statement:INSERT INTO tblOrderDetails (orderid, productid, productcost) VALUES (@orderid, @productid, @productcost)How do i obtain this value and how would I supply it to the second INSERT statement?

Hi All: I have what I'm sure is a common scenario...I have a table to track pageviews of a form, and which also tracks when a person viewing the form submits it.
The table has three fields: an INT identity/PK field, a DATETIME (default getdate()) field, and a BIT field with default "false".
When the page is viewed, I insert a record into the dB:
Protected Sub Page_load(ByVal src As Object, ByVal e As EventArgs)
conn = New SqlConnection("Server=myserver;Database=mydb;User ID=user;Password=password;Trusted_Connection=false;")
If Not IsPostBack Then
AddTrack()
End If
End Sub
Sub AddTrack()
Dim myCommand As SqlCommand
Dim insertTrack As String
insertTrack = "Insert PageTracker (submitted) Values (0)"myCommand = New SqlCommand(insertTrack, conn)
myCommand.Connection.Open()
Try
myCommand.ExecuteNonQuery()tempTxt.Text = "<br>Ticked</b><br>" & insertTrack
Catch ex As SqlException
tempTxt.Text = ex.Number.ToString()
End Try
myCommand.Connection.Close()
End Sub
And if I view the page, the record is inserted into the table. But now I need to know the value of the identity field, so when the form is submitted, I can update the field "submitted" from "0" to "1".
The way I would do it in ASP is to add a "SELECT @@identity" to the query, and get the value using RS.nextrecordset. How would I do this in .NET? or is there a better way for me to do this?

Hi,
I'm nesting a bunch queries, the parent being a select, and the children being inserts. I'd like to retain the auto generated IDs from the original table, and insert them into the new tables (into identity fields). I believe that there is a command that I can use to temporarily turn identity auto numbering off for the current query - can anyone help me with this?
Cheers,
