SQL Server guide

Send a message

Sends an email using the Gmail API. Use INSERT INTO Messages(...) VALUES(...) or SELECT * FROM send_message WITH(...). Supports multiple recipients, Cc, Bcc, and Reply-To; body can be HTML or plain text.

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.

INSERT INTO Messages(From,To,Cc,Bcc,ReplyTo,Subject,Body,MimeType)
VALUES('me'
,'bob@zappysys.com,sam@zappysys.com'
,'some-cc1@zappysys.com,some-cc2@zappysys.com'
,'some-bcc1@zappysys.com,some-bcc1@zappysys.com'
,'reply-to@gmail.com'
,'This is sample HTML email'
,'This is <u>Bob''s</u> HTML email. Sent on <b>*** <<FUN_NOW>> ** </b>'
,'text/html' --or use text/plain for Plain format
)

/*

OR call using SELECT statement 

SELECT * FROM send_message
WITH(From='me'
,To='bob@zappysys.com,sam@zappysys.com'
,Cc='some-cc1@zappysys.com,some-cc2@zappysys.com'
,Bcc='some-bcc1@zappysys.com,some-bcc1@zappysys.com'
,ReplyTo='reply-to@gmail.com'
,Subject='This is sample HTML email'
,Body='This is <u>Bob''s</u> HTML email. Sent on <b>*** <<FUN_NOW>> ** </b>'
,MimeType='text/html' --or use text/plain for Plain format
)

*/

Using OPENQUERY in SQL Server

SELECT * FROM OPENQUERY([LS_TO_GMAIL_IN_GATEWAY], 'INSERT INTO Messages(From,To,Cc,Bcc,ReplyTo,Subject,Body,MimeType)
VALUES(''me''
,''bob@zappysys.com,sam@zappysys.com''
,''some-cc1@zappysys.com,some-cc2@zappysys.com''
,''some-bcc1@zappysys.com,some-bcc1@zappysys.com''
,''reply-to@gmail.com''
,''This is sample HTML email''
,''This is <u>Bob''''s</u> HTML email. Sent on <b>*** <<FUN_NOW>> ** </b>''
,''text/html'' --or use text/plain for Plain format
)

/*

OR call using SELECT statement 

SELECT * FROM send_message
WITH(From=''me''
,To=''bob@zappysys.com,sam@zappysys.com''
,Cc=''some-cc1@zappysys.com,some-cc2@zappysys.com''
,Bcc=''some-bcc1@zappysys.com,some-bcc1@zappysys.com''
,ReplyTo=''reply-to@gmail.com''
,Subject=''This is sample HTML email''
,Body=''This is <u>Bob''''s</u> HTML email. Sent on <b>*** <<FUN_NOW>> ** </b>''
,MimeType=''text/html'' --or use text/plain for Plain format
)

*/')

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_GMAIL_IN_GATEWAY] syntax.

DECLARE @MyQuery NVARCHAR(MAX) = 'INSERT INTO Messages(From,To,Cc,Bcc,ReplyTo,Subject,Body,MimeType)
VALUES(''me''
,''bob@zappysys.com,sam@zappysys.com''
,''some-cc1@zappysys.com,some-cc2@zappysys.com''
,''some-bcc1@zappysys.com,some-bcc1@zappysys.com''
,''reply-to@gmail.com''
,''This is sample HTML email''
,''This is <u>Bob''''s</u> HTML email. Sent on <b>*** <<FUN_NOW>> ** </b>''
,''text/html'' --or use text/plain for Plain format
)

/*

OR call using SELECT statement 

SELECT * FROM send_message
WITH(From=''me''
,To=''bob@zappysys.com,sam@zappysys.com''
,Cc=''some-cc1@zappysys.com,some-cc2@zappysys.com''
,Bcc=''some-bcc1@zappysys.com,some-bcc1@zappysys.com''
,ReplyTo=''reply-to@gmail.com''
,Subject=''This is sample HTML email''
,Body=''This is <u>Bob''''s</u> HTML email. Sent on <b>*** <<FUN_NOW>> ** </b>''
,MimeType=''text/html'' --or use text/plain for Plain format
)
