SqlCeRemoteDataAccess.Push Method (String, String, RdaBatchOption)

Note: This namespace, class, or member is supported only in version 1.1 of the .NET Framework.

Transmits changes from a pulled tracked table in SQL Server CE back to the SQL Server table. These changes can be either individually applied to the server or batched together in a single transaction.

  [Visual Basic]
  Overloads Public Sub Push( _
   ByVal 
  localTableName
   As String, _
   ByVal oledbConnectionString As String, _
   ByVal batchOption As RdaBatchOption _
)
[C#]
public void Push(string localTableName,string oledbConnectionString,RdaBatchOption batchOption
);
[C++]
public: void Push(String* localTableName,String* oledbConnectionString,RdaBatchOption batchOption
);
[JScript]
public function Push(
   localTableName : String,
 oledbConnectionString : String,
 batchOption : RdaBatchOption);

Parameters

• localTableName
  The name of the SQL Server CE table that will receive the extracted SQL Server records. An error occurs if the table already exists.
• oledbConnectionString
  The OLE DB connection string used when connecting to the SQL Server database.
• batchOption
  The option indicates whether the changes being sent back to the SQL Server table should be batched together in a single transaction or individually applied.

Remarks

Applications call the Push method to transmit changes from a pulled tracked SQL Server CE table back to a SQL Server table. The application must have created the local SQL Server CE table by calling the Pull method with RdaTrackOption set to TrackingOn or TrackingOnWithIndexes.

oledbConnectionString specifies all the connect information used while connecting to SQL Server.

If SQL Server Authentication is used, the user ID specified in OLEDBConnectionString must have the authority to read the SQL Server table.

If Windows Authentication is used by setting INTEGRATED SECURITY="SSPI" in OLEDBConnectionString, the Internet user must have the authority to read the SQL Server table. The following identifies the Internet user based on the authentication method:

• When Microsoft Internet Information Services (IIS) virtual directory is configured to use Anonymous access, the Internet user runs under the identity of the Internet Guest Account (IUSR computername). If you configure another Windows user account as the Internet Guest Account, the Internet user runs under the identity of that account.
• When IIS virtual directory is configured to use Basic authentication, the Internet user runs under the identity of the Windows user account for which the client supplied the Internet user name and password.
• When IIS virtual directory is configured to use Integrated Windows authentication, the Internet user runs under the identity of the Windows user account for which the client supplied the Internet user name and password.

If errorTableName was specified when the Pull method was called, any errors that are detected during the Push are logged in the error table. For more information about how the error table works, see "RDA Conflict Detection and Resolution" in SQL Server CE Books Online.

Example

  [Visual Basic] 
' Connection String to the SQL Server.
Dim rdaOleDbConnectString As String = _
    "Provider=sqloledb; Data Source=MySqlServer;Initial Catalog=Northwind; " + "User Id=username;Password = <password>"

' Initialize RDA Object.
Dim rda As SqlCeRemoteDataAccess = Nothing

Try
   'Try the Pull Operation.
   rda = New SqlCeRemoteDataAccess()
   
   rda.InternetLogin         = "MyLogin"
   rda.InternetPassword      = "<password>"
   rda.InternetUrl           = "<http://www.northwindtraders.com/sqlce/sscesa20.dll>"
   rda.LocalConnectionString = "Provider=Microsoft.SQLSERVER.OLEDB.CE.2.0;Data Source=\ssce.sdf"
   
   rda.Push("MyLocalTable", rdaOleDbConnectString, RdaBatchOption.BatchingOn)

Catch e As SqlCeException
'Use you own Error Handling Routine.
'ShowErrors(e);
Finally
   'Dispose of the RDA Object.
   rda.Dispose()
End Try

[C#] 

        // Connection String to the SQL Server.
        string rdaOleDbConnectString  = "Provider=sqloledb; Data Source=MySqlServer;Initial Catalog=Northwind; " +
            "User Id=username;Password = <password>"; 
                                      
        // Initialize RDA Object.
        SqlCeRemoteDataAccess rda = null;

        try {
            //Try the Pull Operation.
            rda = new SqlCeRemoteDataAccess();
            
            rda.InternetLogin          = "MyLogin";
            rda.InternetPassword       = "<password>";
            rda.InternetUrl            = "<http://www.northwindtraders.com/sqlce/sscesa20.dll>";
            rda.LocalConnectionString  = @"Provider=Microsoft.SQLSERVER.OLEDB.CE.2.0;Data Source=\ssce.sdf";
           
            rda.Push("MyLocalTable", 
                rdaOleDbConnectString, 
                RdaBatchOption.BatchingOn);
        }
        catch(SqlCeException) {
            //Use you own Error Handling Routine.
        }
        finally {
            //Dispose of the RDA Object.
            rda.Dispose();
        }
