Querying with the DataAdapter
The CData ADO.NET Provider for SAP BusinessObjects BI implements two ADO.NET interfaces you can use to retrieve data from SAP BusinessObjects BI: SAPBusinessObjectsBIDataAdapter and SAPBusinessObjectsBIDataReader objects. Whereas SAPBusinessObjectsBIDataAdapter objects retrieve a single result set of all the data that matches a query, SAPBusinessObjectsBIDataReader objects fetch data in subset increments as needed.
Using the SAPBusinessObjectsBIDataAdapter
Use the adapter's Fill method to retrieve data from the data source. An empty DataTable instance is passed as an argument to the Fill method. When the method returns, the DataTable instance is populated with the queried data. Note that the SAPBusinessObjectsBIDataAdapter is slower than the SAPBusinessObjectsBIDataReader because the Fill method needs to retrieve all data from the data source before returning.
The following example selects the StoreName and Column1 columns of the MyCustomReport table:
C#
string connectionString = "User=MyUser;Password=MyPassword;Url=http://myserver:6405/biprws;"; using (SAPBusinessObjectsBIConnection connection = new SAPBusinessObjectsBIConnection(connectionString)) { SAPBusinessObjectsBIDataAdapter dataAdapter = new SAPBusinessObjectsBIDataAdapter( "SELECT StoreName, Column1 FROM MyCustomReport", connection); DataTable table = new DataTable(); dataAdapter.Fill(table); Console.WriteLine("Contents of MyCustomReport."); foreach (DataRow row in table.Rows) { Console.WriteLine("{0}: {1}", row["StoreName"], row["Column1"]); } }
VB.NET
Dim connectionString As String = "User=MyUser;Password=MyPassword;Url=http://myserver:6405/biprws;" Using connection As New SAPBusinessObjectsBIConnection(connectionString) Dim dataAdapter As New SAPBusinessObjectsBIDataAdapter("SELECT StoreName, Column1 FROM MyCustomReport", connection) Dim table As New DataTable() dataAdapter.Fill(table) Console.WriteLine("Contents of MyCustomReport.") For Each row As DataRow In table.Rows Console.WriteLine("{0}: {1}", row("StoreName"), row("Column1")) Next End Using
