您如何使用 MS SQL 中的 dbmail 向具有不同标准的多个人发送电子邮件

Question

我正在构建以下 SQL 查询，以向不同的人发送自动电子邮件。现在，我已将其设置为通过电子邮件将 table 发送给一个人。

我想做的是根据条件将特定的查询结果发送给特定的人。例如，我想发送一封仅包含 SC = 20 数据的电子邮件至 abc@email.com，以及另一封包含 sc = 30 的电子邮件至 xyz@email.com.

此外，如果没有该特定 SC 的数据，那么我不会向他们发送电子邮件。

如何调整以适应这种情况？我将不胜感激任何反馈。谢谢。

您可以使用 CURSOR 遍历收件人。

DECLARE @tableHTML NVARCHAR(MAX),
        @Email NVARCHAR(255),
        @Code INT

-- test mapping table 
CREATE TABLE #map ( Email nvarchar(255), Code int   )
insert #map values ('abc@gmail.com', 20)
insert #map values  ('xyz@email.com', 30)

-- CURSOR to iterate through rows in #map
DECLARE mail_cursor CURSOR
FOR SELECT email, code FROM #map
OPEN mail_cursor        

-- Fetch the first row
FETCH NEXT FROM mail_cursor
INTO @Email, @Code

-- Check for successful fetch
WHILE (@@FETCH_STATUS = 0)
BEGIN

    -- Only proceed if there is data to send
    IF (EXISTS (select 1 FROM stu WHERE sc = @Code))
    BEGIN

        -- Build email body. Same as you have, but limit to sc=@code
        SET @tableHTML = N'..'

        -- send to #map.Email
        EXEC msdb.dbo.sp_send_dbmail @recipients=@Email,
            @from_address = 'email@email.com',
            @subject = 'Data Issues',
            @body = @tableHTML,
            @body_format = 'HTML' ;
    END

    -- Fetch the next row
    FETCH NEXT FROM mail_cursor
    INTO @Email, @Code
END

-- Cleanup
CLOSE mail_cursor
DEALLOCATE mail_cursor
DROP TABLE #map
