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 FinancialForceDataReader to retrieve result set metadata. Call GetSchemaTable after calling ExecuteReader.

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

C#

string connectionString = "User=myUser;Password=myPassword;Security Token=myToken;";

using (FinancialForceConnection conn = new FinancialForceConnection(connectionString)) {
  FinancialForceCommand cmd = new FinancialForceCommand("SELECT * FROM Account WHERE Industry = 'Floppy Disks'", conn);
  FinancialForceDataReader 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]);
    }
  }
}

VB.NET

Dim connectionString As String = "User=myUser;Password=myPassword;Security Token=myToken;"

Using conn As New FinancialForceConnection(connectionString)
  Dim cmd As New FinancialForceCommand("SELECT * FROM Account WHERE Industry = 'Floppy Disks'", conn)
  Dim rdr As FinancialForceDataReader = 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))
    Next
  Next
