List events with max results and single events
Limit the number of events returned with MaxResults and expand recurring events into individual instances using SingleEvents='true'. This prevents pagination issues and ensures each occurrence of a recurring event is listed separately.
Example use case: Fetch the next 10 upcoming event instances.
Standard SQL query example
This is the base query accepted by the connector. To execute it in SQL Server, you have to pass it to the Data Gateway via a Linked Server. See how to accomplish this using the examples below.
SELECT * FROM Events
WITH (CalendarId='primary',
MaxResults=10,
SingleEvents='true')
Using OPENQUERY in SQL Server
SELECT * FROM OPENQUERY([LS_TO_GOOGLE_CALENDAR_IN_GATEWAY], 'SELECT * FROM Events
WITH (CalendarId=''primary'',
MaxResults=10,
SingleEvents=''true'')')
Using EXEC in SQL Server (handling larger SQL text)
The major drawback of OPENQUERY is its inability to incorporate variables within SQL statements.
This often leads to the use of cumbersome dynamic SQL (with numerous ticks and escape characters).
Fortunately, starting with SQL 2005 and onwards, you can utilize the EXEC (your_sql) AT [LS_TO_GOOGLE_CALENDAR_IN_GATEWAY] syntax.
DECLARE @MyQuery NVARCHAR(MAX) = 'SELECT * FROM Events
WITH (CalendarId=''primary'',
MaxResults=10,
SingleEvents=''true'')'
EXEC (@MyQuery) AT [LS_TO_GOOGLE_CALENDAR_IN_GATEWAY]
