使用sp_send_dbmail（）發送電子郵件有時不起作用

Question

我使用SQL Server發送通知電子郵件，但有時電子郵件不會發送給用戶。

這裏是我保存它就會發送到用戶

CREATE TABLE [dbo].[EmailNotification](
[Id] [INT] IDENTITY(1,1) NOT NULL, 
[EmailAdress] [NVARCHAR](50) NULL, 
[EmailBody] [NVARCHAR](500) NULL, 
[EmailSubject] [NVARCHAR](250) NULL, 
[Attachment] [NVARCHAR](500) NULL, 
[EmailSent] [BIT] NULL CONSTRAINT [DF_EmailNotification_EmailSent] DEFAULT 
((0)), 
[EmailCreateDate] [DATETIME] NULL CONSTRAINT 
[DF_EmailNotification_EmailCreateDate] DEFAULT (GETDATE()), 
[EmailSentDate] [DATETIME] NULL, 
CONSTRAINT [PK_EmailNotification] PRIMARY KEY CLUSTERED 
([Id] ASC 
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, 
ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] 
) ON [PRIMARY] 

電子郵件我的SQL表，我創建了執行此過程每隔1分鐘的作業

CREATE PROCEDURE [dbo].[spSendEmail] 
AS 
BEGIN 
BEGIN TRAN 
DECLARE @id BIGINT 
DECLARE @max_id BIGINT 
DECLARE @query NVARCHAR(1000) 
DECLARE @EmailBody NVARCHAR(1000) 
DECLARE @EmailAdress NVARCHAR(500) 
DECLARE @EmailSubject NVARCHAR(500) 
DECLARE @attachments NVARCHAR(1000) 

if exists (SELECT * FROM dbo.EmailNotification where EmailSent=0) 
begin 
SELECT @id=MIN(id) FROM dbo.EmailNotification where EmailSent=0 


SELECT @EmailAdress=EmailAdress,@EmailBody=EmailBody,@EmailSubject=EmailSubject,@attachments=Attachment 
FROM EmailNotification WHERE id = @id 


exec [msdb].[dbo].[sp_send_dbmail] @profile_name='Notification', 
@recipients=@EmailAdress, 
@blind_copy_recipients='example.email.com', 
@subject=@EmailSubject, 
@body=@EmailBody, 
@file_attachments=@attachments 

end 
IF(@@ERROR>0) 
BEGIN 
ROLLBACK 
END 
ELSE 
BEGIN 
UPDATE EmailNotification set EmailSent=1, EmailSentDate=getdate() WHERE Id=@id 
COMMIT 
END

你這是什麼意思是：spSendEmail不觸發sp_send_dbmail？ sp_send_dbmail被觸發但不會做任何事情....？

請得到sp_send_dbmail的返回代碼：
0 => OK
<> 0 =>時出錯

DECLARE @result int; 
DECLARE @ErrorNb int; 
EXECUTE @result = exec [msdb].[dbo].[sp_send_dbmail] @profile_name='EDMS email notification', 
@recipients=@EmailAdress, 
@blind_copy_recipients='example.email.com', 
@subject=@EmailSubject, 
@body=@EmailBody, 
@file_attachments=@attachments 
SET @ErrorNb = @@ERROR  

IF @result <> 0 
BEGIN 
-- Something goes wrong 
SELECT @result,@ErrorNb 
END 

您還可以使用TRY：

BEGIN TRY 
    EXECUTE exec [msdb].[dbo].[sp_send_dbmail] @profile_name='EDMS email notification', 
    @recipients=@EmailAdress, 
    @blind_copy_recipients='example.email.com', 
    @subject=@EmailSubject, 
    @body=@EmailBody, 
    @file_attachments=@attachments 
END TRY 
BEGIN CATCH 
    SELECT ERROR_MESSAGE(); 
END CATCH
