Use the adapter's Update method to update the data. This overloaded method can take a DataTable as a parameter and will commit all the changes made to the data source. The name of the data table can be passed as an argument and can also be used to update the entire dataset in a more traditional manner. When using a data table as an argument to the Update method, the adapter evaluates the changes that have been made to the data table and executes the appropriate command for each row (INSERT, UPDATE, or DELETE).

The following example updates the Description of one of the Customer entries.

C#

using (SageX3CloudConnection connection = new SageX3CloudConnection(connectionString)) {
  SageX3CloudDataAdapter dataAdapter = new SageX3CloudDataAdapter(
    "SELECT Name, Description FROM Customer", connection);

  dataAdapter.UpdateCommand = new SageX3CloudCommand(
    "UPDATE Customer SET Description = @Description " +
    "WHERE Id = @Id", connection);
 
  dataAdapter.UpdateCommand.Parameters.Add(new SageX3CloudParameter("@Description", DbType.String, "Description" ));
  dataAdapter.UpdateCommand.Parameters.Add(new SageX3CloudParameter("@Id", DbType.String, "Id" ));
  dataAdapter.UpdateCommand.Parameters[1].SourceVersion = DataRowVersion.Original;

  DataTable table = new DataTable();
  dataAdapter.Fill(table);

  DataRow firstrow = table.Rows[0];
  firstrow["Description"] = "Jon Doe";

  dataAdapter.Update(table);

  Console.WriteLine("Rows after update.");
  
  foreach (DataRow row in table.Rows) {
    Console.WriteLine("{0}: {1}", row["Name"], row["Description"]);
  }
}

VB.NET

Using connection As New SageX3CloudConnection(connectionString)
  Dim dataAdapter As New SageX3CloudDataAdapter(
    "SELECT Name, Description FROM Customer", connection)
  
  dataAdapter.UpdateCommand = New SageX3CloudCommand(
    "UPDATE Customer SET Description = @Description " +
    "WHERE Id = @Id", connection)
  
  dataAdapter.UpdateCommand.Parameters.Add(new SageX3CloudParameter("@Description", DbType.String, "Description" ))
  dataAdapter.UpdateCommand.Parameters.Add(new SageX3CloudParameter("@Id", DbType.String, "Id"))
  dataAdapter.UpdateCommand.Parameters(1).SourceVersion = DataRowVersion.Original
  
  Dim table As New DataTable()
  dataAdapter.Fill(table)
  
  Dim firstrow As DataRow = table.Rows(0)
  firstrow("Description") = "Jon Doe"
  
  dataAdapter.Update(table)
  
  Console.WriteLine("Rows after update.")
  
  For Each row As DataRow In table.Rows
    Console.WriteLine("{0}: {1}", row("Name"), row("Description"))
  Next
End Using

CData Method Extensions

If you want to retrieve the compound primary key after performing an INSERT, the best method to use depends on what type of INSERT was just executed.

If the INSERT was a single update/delete statement, use the connection.GetLastResult() method to retrieve the inserted ID or IDs.

If the INSERT was a batch operation and only one row was updated, use connection.GetLastResult() to get the insertedID. This is the same as retrieving an ID from single update/delete.

If the INSERT was a batch operation and multiple rows were updated, query SYS_LASTRESULTINFO directly to retrieve the inserted IDs from the LASTRESULTINFO#TEMP table.
