In the following example, a stored procedure uses AMO to create partitions for Internet Sales. To do this, it needs to call CurrentDatabaseName to determine the current database name:
public static void CreateInternetSalesMeasureGroupPartitions()
{
//Check the current state of the data warehouse and
//create partitions with AMO if necessary
#region Retrieve order date of last sales transaction
// Open a connection to the data warehouse
// TODO: Change the first string parameter to reflect the right server\instance.
SqlConnection conn = new SqlConnection(string.Format("data source={0};initial catalog={1};Integrated Security=SSPI", "server\\instance", Context.CurrentDatabaseName));
conn.Open();
// Create a command
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
// Get the order date key of the last internet sale
int lastInternetSaleDateKey = 0;
cmd.CommandText = "select max(OrderDateKey) from FactInternetSales";
lastInternetSaleDateKey = (int)cmd.ExecuteScalar();
// Get the order date key of the last reseller sale
int lastResellerSaleDateKey = 0;
cmd.CommandText = "select max(OrderDateKey) from FactResellerSales";
lastResellerSaleDateKey = (int)cmd.ExecuteScalar();

#region Create partitions
// Connect to the calling session
Server svr = new Server();
svr.Connect("*");
// Get the Adventure Works cube
Database db = svr.Databases.GetByName(Context.CurrentDatabaseName);
Cube cube = db.Cubes[0];
MeasureGroup mg;
int maxOrderDateKey;
mg = cube.MeasureGroups.GetByName("Internet Sales");
maxOrderDateKey = 0;
foreach (Partition part in mg.Partitions)
{
maxOrderDateKey = Math.Max(maxOrderDateKey, Convert.ToInt32(
part.Annotations.Find("LastOrderDateKey").Value.Value,
System.Globalization.CultureInfo.InvariantCulture));
}
if (maxOrderDateKey < lastInternetSaleDateKey)
{
Partition part = mg.Partitions.Add("Internet_Sales_"
+ lastInternetSaleDateKey);
part.StorageMode = StorageMode.Molap;
part.Source = new QueryBinding(db.DataSources[0].ID,
"SELECT * FROM [dbo].[FactInternetSales] WHERE OrderDateKey > '"

part.Annotations.Add("LastOrderDateKey", Convert.ToString(lastInternetSaleDateKey,
