List events from all calendars

This example lists events from all calendars accessible to the user. For OAuth, it uses the authenticated user's calendars. For service accounts, specify UserId to impersonate another user (requires domain-wide delegation).

Note: This may return a large dataset; use filters like StartTime to limit results.

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 EventsAll  -- Lists events from all accessible calendars
--WITH (CalendarId='primary',
--      StartTime='<<today,FUN_TO_DATETIME>>-05:00',   
--      EndTime='<<today+7d,FUN_TO_DATETIME>>-05:00')

--OR--
--SELECT * FROM EventsAll WITH(UserId='me') -- for OAuth authenticated user
--SELECT * FROM EventsAll WITH(UserId='someuser@email.com') -- for specific user (requires domain-wide delegation for service accounts)
--SELECT * FROM EventsAll WITH(ContinueOn404Error='False') -- Fail on 404 errors when accessing calendars

Using OPENQUERY in SQL Server

SELECT * FROM OPENQUERY([LS_TO_GOOGLE_CALENDAR_IN_GATEWAY], 'SELECT * FROM EventsAll  -- Lists events from all accessible calendars
--WITH (CalendarId=''primary'',
--      StartTime=''<<today,FUN_TO_DATETIME>>-05:00'',   
--      EndTime=''<<today+7d,FUN_TO_DATETIME>>-05:00'')

--OR--
--SELECT * FROM EventsAll WITH(UserId=''me'') -- for OAuth authenticated user
--SELECT * FROM EventsAll WITH(UserId=''someuser@email.com'') -- for specific user (requires domain-wide delegation for service accounts)
--SELECT * FROM EventsAll WITH(ContinueOn404Error=''False'') -- Fail on 404 errors when accessing calendars')

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 EventsAll  -- Lists events from all accessible calendars
--WITH (CalendarId=''primary'',
--      StartTime=''<<today,FUN_TO_DATETIME>>-05:00'',   
--      EndTime=''<<today+7d,FUN_TO_DATETIME>>-05:00'')

--OR--
--SELECT * FROM EventsAll WITH(UserId=''me'') -- for OAuth authenticated user
--SELECT * FROM EventsAll WITH(UserId=''someuser@email.com'') -- for specific user (requires domain-wide delegation for service accounts)
--SELECT * FROM EventsAll WITH(ContinueOn404Error=''False'') -- Fail on 404 errors when accessing calendars'
EXEC (@MyQuery) AT [LS_TO_GOOGLE_CALENDAR_IN_GATEWAY]
