SQL Server SP_SEND_DBMAIL 图像文件附件
[英]SQL Server SP_SEND_DBMAIL Image file attachment
问题描述
I am using a trigger on a table to send an email using sp_send_dbmail.
我在表上使用触发器来使用 sp_send_dbmail 发送电子邮件。
I want to include a file attachment in the email of an image type.我想在图像类型的电子邮件中包含文件附件。
The raw data for the jpeg is stored in the ndl_Image column which is of type binary. jpeg 的原始数据存储在二进制类型的 ndl_Image 列中。
I have the following code:-我有以下代码：-
DECLARE @ReferenceID varchar(max)
DECLARE @Recipient varchar(Max)
DECLARE @Body varchar(max)
DECLARE @Subject varchar(max)
DECLARE @Q varchar(max)
--Get the EntryId and FormID for the inserted data.
SET @ReferenceID = 40
SET @Recipient = (SELECT ndl_CategorySendTo FROM ndl_config WHERE ndl_CategoryName = 'Dead Animal')
SET @Body = '<html>A new request has been created.</html>'
SET @Subject = 'NDL Report It: New Request #'+@ReferenceID
SET @Q = 'SELECT ndl_Image from dbo.ndl_data where ndl_ID ='+@ReferenceID
--Execute the stored procedure to send mail.
EXEC msdb.dbo.sp_send_dbmail
--Pass it the following paramaters.
@recipients=@Recipient,
@body=@Body,
@subject=@Subject,
@profile_name='NDLProfile',
@body_format ='HTML',
@execute_query_database='NDL_MX',
@query = @Q,
@attach_query_result_as_file = 1,
@query_attachment_filename = 'image.jpg'
This works ok but seems to return the query as a text file if i comment out the last line.这工作正常，但如果我注释掉最后一行，似乎将查询作为文本文件返回。
How can I get the attachment as a jpeg file????如何将附件作为 jpeg 文件获取？？？？
Thanks.谢谢。

I don't think this is possible. 我不认为这是可能的。 As specified in the documentation for SP_SEND_DBMAIL : 如SP_SEND_DBMAIL的文档中所述 ：
"When a query is specified, the result set is formatted as inline text. Binary data in the result is sent in hexadecimal format. "[emphasis added]

The sample below will imbed images into the < img > tag, which will work for jpeg, png, and such.下面的示例将图像嵌入到 <img> 标签中，该标签适用于 jpeg、png 等。 It won't solve PDFs, but it does work with images, at least.它不会解决 PDF，但至少可以处理图像。
