(SQL Server) Google Calendar Search Events (List Events with Optional Query Parameters)

See more Google Calendar Examples

Demonstrates how to specify optional query parameters for listing events. This example uses the "q" parameter to free-text search for events, and uses the "timeMin" parameter to specify a lower bound for an event's end time.
