List calendars

This example retrieves a list of calendars accessible to the authenticated user or specified user. Use UserId='me' for the current user (OAuth) or a specific email for service accounts with domain-wide delegation.

Note: For service accounts, impersonation may be required for non-'me' users.

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 Calendars
-- Default: Lists calendars for the authenticated user

--OR--
--SELECT * FROM Calendars WITH(UserId='me') -- for OAuth authenticated user
--SELECT * FROM Calendars WITH(UserId='someuser@email.com') -- for specific user (requires domain-wide delegation for service accounts)

Using OPENQUERY in SQL Server

SELECT * FROM OPENQUERY([LS_TO_GOOGLE_CALENDAR_IN_GATEWAY], 'SELECT * FROM Calendars
-- Default: Lists calendars for the authenticated user

--OR--
--SELECT * FROM Calendars WITH(UserId=''me'') -- for OAuth authenticated user
--SELECT * FROM Calendars WITH(UserId=''someuser@email.com'') -- for specific user (requires domain-wide delegation for service accounts)')

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 Calendars
-- Default: Lists calendars for the authenticated user

--OR--
--SELECT * FROM Calendars WITH(UserId=''me'') -- for OAuth authenticated user
--SELECT * FROM Calendars WITH(UserId=''someuser@email.com'') -- for specific user (requires domain-wide delegation for service accounts)'
EXEC (@MyQuery) AT [LS_TO_GOOGLE_CALENDAR_IN_GATEWAY]
