ADO.NET Provider for Smartsheet

Build 24.0.9060

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 SmartsheetDataReader 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 = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;";

using (SmartsheetConnection conn = new SmartsheetConnection(connectionString)) {
  SmartsheetCommand cmd = new SmartsheetCommand("SELECT * FROM Sheet_Test_Sheet WHERE Favorite = 'True'", conn);
  SmartsheetDataReader 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 = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;"

Using conn As New SmartsheetConnection(connectionString)
  Dim cmd As New SmartsheetCommand("SELECT * FROM Sheet_Test_Sheet WHERE Favorite = 'True'", conn)
  Dim rdr As SmartsheetDataReader = 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
