无法在SQL中开发电子邮件正文

Question

我编写了一个存储过程，其中＆＃34;我必须比较两个表中的值并将邮件发送给第二个表中不存在的用户。

我必须自动化这份报告。

但问题出现的时候，我正在努力制作邮件正文。

邮件正文取自表record，即列名REQ_Approval_EMAILBODY。Recipient id也必须从表记录中取出，即名称REQ_Approval_EMAILID。< / p>

此查询必须逐个执行所有记录，并使用表中的相应电子邮件ID。

请帮我梳理他的。

提前致谢

Answer 1

试试这个

select @para = concat('<p style="font-family:arial; font-size:14px">Dear Team,</br></br>', [REQ_Approval_EMAILBODY],'</br></p>')
from #Temp3_New_Table 
{where condition}

修改 如果你想要一个光标，那么你可以尝试这个

DECLARE evilCurse CURSOR FOR
    SELECT [REQ_Approval_EMAILID]
          ,[REQ_Approval_EMAILBODY] = concat('<p style="font-family:arial; font-size:14px">Dear Team,</br></br>', [REQ_Approval_EMAILBODY],'</br></p>')
          ,[REQ_Approval_EMAIL_Subject]
      FROM [SAEI].[dbo].[Approval_EMAIL_LOG] 
      where CONVERT(DATE,REQ_SentDate) = @Yesterday
      and res_date is null
      and req_approval_number+req_order_number+req_document_number not in
            (SELECT [RES_Approval_Number]+[RES_Order_Number]+[RES_Document_Number] 
            FROM [SAEI].[dbo].[Approval_Response_WEB_LOG])

OPEN evilCurse
FETCH NEXT FROM evilCurse
INTO @Recipients, @bodynew, @subjects
WHILE @@FETCH_STATUS = 0
BEGIN
    --do what ever you want to do to here 

    FETCH NEXT FROM evilCurse
    INTO @Recipients, @bodynew, @subjects
END

CLOSE evilCurse;
DEALLOCATE evilCurse;
