Hi
Thanks for ur reply..BUT..i am talking in the context of ADO.NET not SQL Server.
I am trying to map sql command parameters of a sql command object to columns of a data table to update the table back to the DB.
It seems that ADO.NET does not allow such a mapping to COMPUTED columns (data columns with thier EXPRESSION property filled)
is there a work around?

hello ...
I have a big problem with an application.
with this application i have to open an access file on a server somewhere in the net.
the clients use my app to open this access-file.
i used ODBC, i use DAO ... but always there must be something installed on the clients that i can open the access-file (mdac, jet,...)
but i need a solution where i can start the app-exe on a naked client (no installation of jet before). it is ok, if dll's are in the app-directory ...
how can i do this ??????????????????????????????????
P.S. the database must be a file ... no server ...

You are out of luck, IMO. you will have to install at least MDAC & Jet on the client.

Hello...
I have the following situation :
One data set that contains two data tables, tblHeader and tblDetails. The two tables have a column in common (like a relation).
Dim con as New SqlCOnnection()
Dim da as New SqlDataAdapter()
Dim cmd as New SqlCommand("sp_insertrecord", con)
da.InsertCommand = cmd
da.InsertCommand.CommandType = CommandType.StoredProcedure
da.InsertCommand.Parameters.Add(New SqlParameter("@Param1", SqlDbType.VarChar, 40, strCol1))
da.InsertCommand.Parameters.Add(New SqlParameter("@Param2", SqlDbType.VarChar, 3, strCol2))
da.InsertCommand.Parameters.Add(New SqlParameter("@Param3", SqlDbType.VarChar, 10, strCol3))
as U can see strCol1,strCol2 and strCol3 are source columns that map to the columns that i want to update. The problem is that I have col1 in tblHeader and Col2 and Col3 in tblDetails....
when I execute
da.Update(ds,tblDetails.TableName)
I get an error stating the sp_InsertRecords expects paramter @Param1 that was not supplied.
I guess that the situation is happening because I have one row in the header table and 3 rows in the details table...
How can I map the paramter to the correct column name in the second table??..how should i modify my da.update statement???
what I need is a sort of an INNER JOIN in ADO.NET..is there such a thing??
Please Help Me
Thanks In Advance

Hi guys
I wonder if it is possible to select some range of rows from a teble. For example suppose that I want to retrieve 12th-24th records from a table which has 100 records. Is it possible? If so, what is the SQL query?

You should use TOP keyword in combination of ORDER BY, something like this:
SELECT TOP 12 FROM table ORDER BY primaykey DESC WHERE primarykey < 24
Maybe this statement doesn't work, but you should find it with TOP keyword.

I want to do that independent of primary key.

yes but 12th - 24th based on what sort criteria?
just change the order by criteria in mazzy's example and it will work

I have dragged a query from an access database onto a web form, configured the oledbadapter to point to the correct connection, generated a dataset out of that, and in the properties box of the datagrid I have set its datasource and other properties. If I do a preview of the dataset and fill it, it shows the data.
However, when I view in browser the datagrid does not even show up.
I have not used any behind code in this as far as binding the dataset to the datagrid, etc. b/c I am thinking that it was already set when I changed the property settings for that datagrid.... Am I correct in thinking this? If so, does anyone know why my datagrid will not show up?
Thanks

Have you add mydataadapter.Fill(dataset); in your code-behind?

Hi,
I'm doing ASP.NET application.
What is the type of the SqlParameter.Value to call a stored procedure expecting a nvarchar parameter?
I tried to simply use a string, but it fails (code compiles, but the stored procedure returns nothing).
I tried also to cast the string to a SqlDbType.Nvarchar, but I didn't manage.
Thanks for help, sorry if I'm not clear ...

String should work. What does the stored proc look like?
|

Hi,
The procedure:
ALTER PROCEDURE matthieu77.GetUserByName ( @Nom nvarchar )
AS
SELECT UserID, Nom
FROM Users
WHERE Nom=@Nom
RETURN
The code that calls this proc:
SqlParameter param = new SqlParameter ("@Nom",SqlDbType.NVarChar);
param.Direction=ParameterDirection.Input;
param.Value="Bonjour";
SqlDataAdapter ad = new SqlDataAdapter();
ad.SelectCommand = new SqlCommand();
ad.SelectCommand.Connection = sqlConnection1;
ad.SelectCommand.CommandText = "GetUserByName";
ad.SelectCommand.CommandType =CommandType.StoredProcedure;
ad.SelectCommand.Parameters.Add(param);
ad.Fill(dataSet11,"Users");
DataGrid1.DataBind();
If I replace in the stored procedure Nom='Bonjour' it works fine.
Regards,
Matthieu

I am trying to access and pull data into a datagrid from a MS Access database located on a network drive. Everytime I try and run the project I get this error:
The Microsoft Jet database engine cannot open the file '\\Jxn-nt-tmsus\e\LISTEST\e214.mdb'. It is already opened exclusively by another user, or you need permission to view its data.
I know there is no one else in the file and i have rights to access the file.
Any suggestions?
THanks very much

If you're talking about ASP.NET, make sure the YourMachineName\ASPNET user account has read/modify permissions on the folder containing the .mdb file.

Marcie,
I copied the database to my local machine and I can access the data fine.
As soon as I try to access it on the remote location... I get the error.
I do not see a user account on the Intranet domain for ASPNET... does there need to be one on that level or do I need to make sure that just myMachine/ASPNET user account can read/modify that remote folder..
Thanks!!

The EVERYONE account has Full Control access to the folder and file... wouldnt that include any ASPNET account that could possibly be in there?
Thanks

I'm doing some test with sql connection polling using sqlconnection object.
I've read some articles stating that the Dispose method of the connection removes the connection from the pool, but in my tests the Dispose doesn't remove it from the pool (I'm checking the audit logout event in the SQL Trace). The audit logout only happens when I close the application.
My question is... does the dispose method remove the connection from the pool or not !?
