ASP.NET how to read from a table and insert into a second table SQL Server ?

I have two aspx web forms in asp.net 3.5. In one form I am authentication users against a table which have information, I am using two fields to check : employee id and SS N,

Once the credentials are accepted, I take them to a survey page,

How Do I create a Stored Procedure or a Code in ADO.NET to read the values of several columns from the logged in userid, from this table ( empInfor) and Insert into a second table located at another sql server instance at Submit Button CLick?

Below is the code which checks the user
protected void LogIn(object sender, ImageClickEventArgs e)     {          //Method that checks employee id and SSN against empInfo Table          string strconn = WebConfigurationManager.ConnectionStrings["wfcdbConnectionString"].ConnectionString;          using (SqlConnection conn = new SqlConnection(strconn))         {             conn.Open();              string cmdStr = "select count(*) from [empInfo]";             cmdStr += " where ID='" + UserName.Text + "'";             cmdStr += " and RIGHT(SSN,4)='" + Password.Text + "'";             SqlCommand cmd = new SqlCommand(cmdStr, conn);              int i = Convert.ToInt16(cmd.ExecuteScalar());              if (i == 0)             {                 LtlLogin.Text = "<div id='lit1'> <p>Error: Incorrect login details provided.</p></div>";                 Session["empCheck"] = false;             }              else             {                 Session["empCheck"] = true;                  //Create a New Session Var                  Session["empId"] = UserName.Text;                 Response.Redirect("Main.aspx");             }

On Page_Load():
{
 Check which user has logged in by using employeeID(assuming employee is the user)
 Then use DataSet (Or DataTable) to get the what ever information you need to have from table 1 of SQL Server 1  PLUS store survey responses and store them in some Session variables
}

On Button Click Event()
{
 Pass all these values (Session variable values) to insert/update query you have for Table 1 of SQL Server 2.

what would be a better approach, to pass the id and open a new connection into the insert page, or to pass the session values from table 1 , (connection on page 1 only to pulll values)

and second page insert the session values plus the survey value fields?

Should I use a datareader or datatable or how do I perform the reading?

The best way I can think of to accomplish this is via sp_addlinkedserver. You need to make sure that whatever account you use to add the link (via sp_addlinkedsrvlogin) has permissions to the table you're joining, but then once the link is established, you can call the server by name, i.e.:

SELECT *
FROM server1table
INNER JOIN server2.database.dbo.server2table ON .....

So can write single storedprocedure to retrieve data from one instance and insert into other instance.

Hope this helps.

I can suggest you an outline of solution , you can verify syntax and use it as needed.

select from table
set conn = Server.CreateObject("adodb.connection")
conn.open("DSN=TestServer;UID=sa;PWD=sa123x;DATABASE=EDI;")
set rs=Server.CreateObject("ADODB.recordset")
sql1 =  "select * from table1";
rs.open sql1, conn

Open in new window


set parameters
column1 = rs.Fields("fieldname1").Value
.....

Open in new window


insert into other table
set conn1 = Server.CreateObject("adodb.connection")
conn1.open("DSN=TestServer;UID=sa;PWD=sa123x;DATABASE=EDI;")
set rs1=Server.CreateObject("ADODB.recordset")
sql2 =  "insert into table2 values('"+column1 +"')";
rs.open sql2, conn1

Open in new window

that looks more like a classic asp syntax, mine is asp.net c#
