Ejemplos

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();
    #endregion

    #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 > '"
            + maxOrderDateKey + "' and OrderDateKey <= '" + lastInternetSaleDateKey + "'");
        part.Annotations.Add("LastOrderDateKey", Convert.ToString(lastInternetSaleDateKey,
            System.Globalization.CultureInfo.InvariantCulture));
        part.Update();
        part.Process();
    }

    svr.Disconnect();

    #endregion
