ADO.NET Provider for Airtable

Build 21.0.7930

Querying with the DataReader

The CData ADO.NET Provider for Airtable implements two ADO.NET interfaces you can use to retrieve data from Airtable: AirtableDataAdapter and AirtableDataReader objects. Whereas AirtableDataAdapter objects retrieve a single result set of all the data that matches a query, AirtableDataReader objects fetch data in subset increments as needed.

Using the AirtableDataReader

The AirtableDataReader retrieves data faster than the AirtableDataAdapter because it can retrieve data in pages. As you read data from the AirtableDataReader, it periodically requests the next page of results from the data source, if required. This causes results to be returned at a faster rate. The following example selects all the columns from the SampleTable_1 table:

C#

string connectionString = "APIKey=keymz3adb53RqsU;BaseId=appxxN2fe34r3rjdG7;TableNames=TableA,TableB,TableC;ViewNames=TableA.ViewA,TableA.ViewB,..,TableX.ViewY;";

using (AirtableConnection connection = new AirtableConnection(connectionString)) {
  AirtableCommand cmd = new AirtableCommand("SELECT * FROM SampleTable_1", connection);
  
  AirtableDataReader rdr = cmd.ExecuteReader();

  while (rdr.Read()) {
    Console.WriteLine(String.Format("\t{0} --> \t\t{1}", rdr["Id"], rdr["Column1"]));
  }
}

VB.NET

Dim connectionString As String = "APIKey=keymz3adb53RqsU;BaseId=appxxN2fe34r3rjdG7;TableNames=TableA,TableB,TableC;ViewNames=TableA.ViewA,TableA.ViewB,..,TableX.ViewY;"

Using connection As New AirtableConnection(connectionString)
  Dim cmd As New AirtableCommand("SELECT * FROM SampleTable_1", connection)

  Dim rdr As AirtableDataReader = cmd.ExecuteReader()

  While rdr.Read()
    Console.WriteLine([String].Format(vbTab & "{0} --> " & vbTab & vbTab & "{1}", rdr("Id"), rdr("Column1")))
  End While
End Using
