Question

我使用sp_send_dbmail生成并发送送到其他程序的文件。该程序摘要“ANSI / ASCII”和“ISO-8859-1”编码。但我无法让sp_send_dbmail成为一个。

程序调用如下所示

exec msdb.dbo.sp_send_dbmail 
    @profile_name= @profile_name, 
    @recipients  = @recipients,
    @body = @body,
    @subject = @subject,
    @attach_query_result_as_file = 1, 
    @query_result_header = 0,
    @query_result_no_padding = 1,
    @query = @query,
    @query_attachment_filename = @fname,
    @query_result_width = 4000,
    @mailitem_id = @mailitem_id OUTPUT

因此附件是根据传递的查询结果创建的。但由于某种原因实际附加到邮件的结果文件是用UCS2 Little Endian编码的。有没有办法改变它？

找到允许在UTF / ANSI之间切换的解决方法。为此，您需要像这样修改sp_send_dbmail：

向过程添加新参数，例如@ANSI_Attachment BIT = 0
替换其代码段IF(@AttachmentsExist = 1) BEGIN ....... END 与

`IF（@AttachmentsExist = 1）

BEGIN
    if (@ANSI_Attachment = 1) 
    begin
        --Copy temp attachments to sysmail_attachments      
        INSERT INTO sysmail_attachments(mailitem_id, filename, filesize, attachment)
        SELECT @mailitem_id, filename, filesize, 
                convert(varbinary(max), 
                    substring( -- remove BOM mark from unicode
                        convert(varchar(max), CONVERT (nvarchar(max), attachment)), 
                        2, DATALENGTH(attachment)/2
                    )
                )
        FROM sysmail_attachments_transfer
        WHERE uid = @temp_table_uid
    end else begin
        --Copy temp attachments to sysmail_attachments      
        INSERT INTO sysmail_attachments(mailitem_id, filename, filesize, attachment)
        SELECT @mailitem_id, filename, filesize, attachment
        FROM sysmail_attachments_transfer
        WHERE uid = @temp_table_uid
    end
END `

这样做相同，但如果在程序中调用@ANSI_Attachment = 1，它会在发送之前删除unicode BOM标记。
