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 NetSuiteDataReader 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 = "AccountId=XABC123456;Schema=SuiteTalk;AuthScheme=Token;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;OAuthAccessToken=MyOAuthAccessToken;OAuthAccessTokenSecret=MyOAuthAccessTokenSecret;";

using (NetSuiteConnection conn = new NetSuiteConnection(connectionString)) {
  NetSuiteCommand cmd = new NetSuiteCommand("SELECT * FROM Account WHERE acctName = 'Checking'", conn);
  NetSuiteDataReader 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 = "AccountId=XABC123456;Schema=SuiteTalk;AuthScheme=Token;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;OAuthAccessToken=MyOAuthAccessToken;OAuthAccessTokenSecret=MyOAuthAccessTokenSecret;"

Using conn As New NetSuiteConnection(connectionString)
  Dim cmd As New NetSuiteCommand("SELECT * FROM Account WHERE acctName = 'Checking'", conn)
  Dim rdr As NetSuiteDataReader = 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
End Using
