Post DBMail can't use mySendMail function Reply with quote

The examples under Sending Emails, Microsoft SQL Server, Example 2, shows that you can create a function and then use it in a select statement.
Unfortunately this won't work.

I keep getting the following error message.

Server: Msg 557, Level 16, State 2, Procedure mySendMail, Line 8
Only functions and extended stored procedures can be executed from within a function.

Has anyone found a way around this without creating an extended stored procedure?

1. To overcome that SQL Server limitation you can modify mySendMail code as the following

CREATE FUNCTION mySendMail( @recipient VARCHAR(30), @subject VARCHAR(255), @message VARCHAR(8000)) RETURNS INT
AS
BEGIN
DECLARE @ret INT
EXEC @ret = master.dbmail.SendMail @recipient, @subject,
@message, 'helpdesk@domain.com'

INSERT INTO dbmail.pipe
(message_type, recipients, subject, message,
reply_to, content_type, priority, attachment_id)
VALUES ('EMAIL', @recipient, @subject, @message,
'helpdesk@domain.com', 'text/plain', 1, NULL )

RETURN (@@identity)
END

This way you can call it from anywhere.

2. Please check out excellent article about calling UDFs and known workarounds http://msdn.microsoft.com/SQL/sqlreldata/TSQL/default.aspx?pull=/library/en-us/dnsqlpro03/html/sp03e9.asp

CREATE PROCEDURE dbmail.SendMail(

@recipients VARCHAR(8000),

@subject VARCHAR(255),

@message VARCHAR(8000),

@reply_to VARCHAR(255) = NULL,

@content_type VARCHAR(50) = 'text/plain',

@priority INT = 1,

@attachment_id INT = NULL)
AS

/*****************************************************************/

/* dbmail.SENDMAIL procedure - use this procedure to send email */

/* messages. */

/* Email send method (SMTP, MAPI, Lotus Notes) should */

/* be configured in DB Mail console */

/*****************************************************************/
BEGIN

INSERT INTO dbmail.pipe

(message_type, recipients, subject, message,

reply_to, content_type, priority, attachment_id)

VALUES ('EMAIL', @recipients, @subject, @message,

@reply_to, @content_type, @priority, @attachment_id )

RETURN @@identity
END
