ADO.NET Provider for SAP ByDesign

Result Sets

You can access the same column information about the results of a query that you can for table schemas. See Columns for the columns returned.

Retrieving Result Set Metadata

You can use the GetSchemaTable method of the SAPByDesignDataReader to retrieve result set metadata. Call GetSchemaTable after calling ExecuteReader.

Each row of the DataTable describes a column in the query's result.


string connectionString = "URL=;User=username;Password=password;CustomService=servicename;";

using (SAPByDesignConnection conn = new SAPByDesignConnection(connectionString)) {
  SAPByDesignCommand cmd = new SAPByDesignCommand("SELECT * FROM Account WHERE Industry = 'Floppy Disks'", conn);
  SAPByDesignDataReader rdr = cmd.ExecuteReader();
  DataTable schemaTable = rdr.GetSchemaTable();
  foreach (DataRow row in schemaTable.Rows) {
    foreach (DataColumn col in schemaTable.Columns) {
      Console.WriteLine("{0}: {1}", col.ColumnName, row[col]);


Dim connectionString As String = "URL=;User=username;Password=password;CustomService=servicename;"

Using conn As New SAPByDesignConnection(connectionString)
  Dim cmd As New SAPByDesignCommand("SELECT * FROM Account WHERE Industry = 'Floppy Disks'", conn)
  Dim rdr As SAPByDesignDataReader = cmd.ExecuteReader()
  Dim schemaTable As DataTable = rdr.GetSchemaTable()
  For Each row As DataRow In schemaTable.Rows
    For Each col As DataColumn In schemaTable.Columns
      Console.WriteLine("{0}: {1}", col.ColumnName, row(col))
End Using
