Gets or sets Salesforce.com or Database.com statement used to update records in the data source.

Syntax

'Declaration
 
Public Shadows Property UpdateCommand As SalesforceCommand

public new SalesforceCommand UpdateCommand {get; set;}

Property Value

A SalesforceCommand used during an update operation to update records in the data source that correspond to modified rows in the System.Data.DataSet.

Remarks

During an update operation, if UpdateCommand is not set and primary key information is present in the System.Data.DataSet, you can use the SalesforceCommandBuilder class to automatically generate UpdateCommand, and additional commands needed to reconcile the System.Data.DataSet to the data source. To do this, set the SelectCommand property of the SalesforceDataAdapter. For more information see "Automatically Generated Commands" in the Microsoft .NET Framework SDK documentation.

Note: If execution of this command returns rows, these rows may be merged with the System.Data.DataSet depending upon how you set the Devart.Common.DbCommandBase.UpdatedRowSource property of the SalesforceCommand object.

Example

The following example demonstrates how to retrieve and manipulate data using SalesforceDataAdapter.

csharp

public void UseDataAdapter(SalesforceConnection salesforceConnection) 
{ 
        SalesforceDataAdapter myAdapter = new SalesforceDataAdapter("SELECT ID, Name FROM Account", salesforceConnection); 
        myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey; 
        DataSet myDataSet = new DataSet(); 
        myAdapter.Fill(myDataSet,"Accounts"); 
        myDataSet.Tables["Accounts"].Rows[3]["Name"] = "Edited account"; 
        myAdapter.UpdateCommand = new SalesforceCommand("UPDATE Accounts SET Name = :Name " + 
                "WHERE ID = :ID", salesforceConnection); 
        myAdapter.UpdateCommand.Parameters.Add("ID", SalesforceType.String, 18, "ID"); 
        myAdapter.UpdateCommand.Parameters.Add("Name", SalesforceDbType.String, 255, "Name"); 
        myAdapter.Update(myDataSet,"Account");  
        //Get all data from all tables within the dataset 
        foreach(DataTable myTable in myDataSet.Tables) 
        { 
                foreach(DataRow myRow in myTable.Rows) 
                { 
                        foreach (DataColumn myColumn in myTable.Columns) 
                        { 
                                Console.Write(myRow[myColumn]+"\t"); 
                        } 
                        Console.WriteLine(); 
                } 
                Console.WriteLine(); 
        } 
}

Visual Basic

Public Sub UseDataAdapter(salesforceConnection As SalesforceConnection)
        Dim myAdapter As New SalesforceDataAdapter("SELECT ID, Name FROM Account", salesforceConnection)
        myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey
        Dim myDataSet As New DataSet()
        myAdapter.Fill(myDataSet, "Accounts")
        myDataSet.Tables("Accounts").Rows(3)("Name") = "Edited account"
        myAdapter.UpdateCommand = New SalesforceCommand("UPDATE Accounts SET Name = :Name " & _
           "WHERE ID = :ID", salesforceConnection)
        myAdapter.UpdateCommand.Parameters.Add("ID", SalesforceType.String, 18, "ID")
        myAdapter.UpdateCommand.Parameters.Add("Name", SalesforceDbType.String, 255, "Name")
        myAdapter.Update(myDataSet, "Account")
        'Get all data from all tables within the dataset 
        For Each myTable As DataTable In myDataSet.Tables
                For Each myRow As DataRow In myTable.Rows
                        For Each myColumn As DataColumn In myTable.Columns
                                Console.Write(myRow(myColumn) + vbTab)
                        Next
                        Console.WriteLine()
                Next
                Console.WriteLine()
        Next
End Sub
