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 QuickBaseDataReader 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 = "[email protected];Password=test_1234;Domain=test.quickbase.com;ApplicationToken='bwkxrb5da2wn57bzfh9xn24';";

using (QuickBaseConnection conn = new QuickBaseConnection(connectionString)) {
  QuickBaseCommand cmd = new QuickBaseCommand("SELECT * FROM [CData].[QuickBase].SampleTable_1 WHERE Column2 = 'Bob'", conn);
  QuickBaseDataReader 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 = "[email protected];Password=test_1234;Domain=test.quickbase.com;ApplicationToken='bwkxrb5da2wn57bzfh9xn24';"

Using conn As New QuickBaseConnection(connectionString)
  Dim cmd As New QuickBaseCommand("SELECT * FROM [CData].[QuickBase].SampleTable_1 WHERE Column2 = 'Bob'", conn)
  Dim rdr As QuickBaseDataReader = 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
