我有一个像魅力一样工作的存储过程，我对此非常满意。为了做到完美，我只需要它做更多的事情。如果没有满足任何参数，它什么也不返回，或者它只是说“找到一个”，如果选择有一些东西要返回。现在，粗糙的部分。这个数据库有一些有截止日期的档案。当该截止日期到来时，我收到一封电子邮件，上面写着“嘿，其中一个档案已达到到期日期”。我需要的是从该特定档案中获取一些数据，编号，参考，名称，......我如何通过该程序达到这一点，以避免检查所有可能的档案以查看哪个档案终止。

我无法解决这个问题，很抱歉:(在早期的 sql-server 版本上具有相同的过程，它返回了该数据，我不记得为此做了任何事情

CREATE PROCEDURE dbo.DossierEmailSend
 AS
 DECLARE @rows int;
 DECLARE @message varchar(1000);
 SET @rows = (SELECT COUNT(*)  
            FROM bo
            WHERE nmdos LIKE '%preço%'
            AND datafinal = DATEADD(day, -1, CONVERT(date, GETDATE()))
            )
 SET NOCOUNT ON 
 SET @message = '<HTML>As at ' + CONVERT(char(19),GETDATE(),120) + '<BR><BR>ONE UP'

 IF @rows > 0 
 BEGIN

 EXEC dbo.uspSendEmail 'aaaaaaa', 'aaaaaaaa@aaaa', @message, NULL, 'CC EMAIL 1'
 SET NOCOUNT OFF

 END

我刚收到消息说其中一份档案已到最后期限，需要知道哪一份

因为要求是将多行传递到电子邮件的正文，所以最好以表格格式提供。

这可以通过在电子邮件正文中包含符合标准的达析报告的 HTML 表格来实现。

只需将列名替换为表 bo 中的正确名称即可。

让我们单独分解元素：

CREATE PROCEDURE dbo.DossierEmailSend
AS

为符合条件的达析报告创建一个保留表

DECLARE @dossiers TABLE (col1 varchar(100), col2 varchar(100), col3 varchar(100), col4 varchar(100));

插入符合条件的达析报告

INSERT INTO @dossiers
SELECT col1, col2, col3, convert(varchar,col4) col4  
    FROM bo
    WHERE nmdos LIKE '%preço%'
    AND datafinal = DATEADD(day, -1, CONVERT(date, GETDATE()))

创建行检查以确定是否发送电子邮件

DECLARE @rows int;
SET @rows = (SELECT COUNT(*) FROM @dossiers)

检查是否有任何档案符合标准

IF @rows > 0 
BEGIN

设置正文元素

DECLARE @message varchar(1000);
-- declare the xml data to pass to the HTML body
DECLARE @xml NVARCHAR(MAX);
-- body will hold the HTML formatted table in the email
DECLARE @body NVARCHAR(MAX);

创建将每行数据保存为 xml 的列

SET @xml = CAST(( SELECT col1 AS 'td','',col2 AS 'td','', col3 AS 'td','', col4 AS 'td'
FROM @dossiers
FOR XML PATH('tr'), ELEMENTS ) AS NVARCHAR(MAX))

设置正文的 HTML

SET @body ='<html><body><H3>Dossier Info</H3>
<table border = 1> 
<tr>
<th> col1 </th> <th> col2 </th> <th> col3 </th> <th> col4 </th></tr>'

将所有内容拼接在一起，附加 HTML 表格

SET @body = @body + @xml +'</table></body></html>'

SET NOCOUNT ON

发送电子邮件并将数据表附加到正文

EXEC dbo.uspSendEmail 'Dossiers FOund', 'aaaaaaaa@aaaa', @body, NULL, 'CC EMAIL 1'
SET NOCOUNT OFF

END

完成的解决方案应如下所示：

CREATE PROCEDURE dbo.DossierEmailSend
AS
 --Create a holding table for the dossiers that met the criteria

DECLARE @dossiers TABLE (col1 varchar(100), col2 varchar(100), col3 varchar(100), col4 varchar(100));

 --Insert the dossiers that met the criteria

INSERT INTO @dossiers
SELECT col1, col2, col3, convert(varchar,col4) col4  
    FROM bo
    WHERE nmdos LIKE '%preço%'
    AND datafinal = DATEADD(day, -1, CONVERT(date, GETDATE()))

 --Create a row check to determine whether to send the email or not

DECLARE @rows int;
SET @rows = (SELECT COUNT(*) FROM @dossiers)

 --Check if any dossiers met the criteria

IF @rows > 0 
BEGIN

 --Set the body elements

DECLARE @message varchar(1000);
-- declare the xml data to pass to the HTML body
DECLARE @xml NVARCHAR(MAX);
-- body will hold the HTML formatted table in the email
DECLARE @body NVARCHAR(MAX);

 --Create the columns that will hold each row of data as xml

SET @xml = CAST(( SELECT col1 AS 'td','',col2 AS 'td','', col3 AS 'td','', col4 AS 'td'
FROM @dossiers
FOR XML PATH('tr'), ELEMENTS ) AS NVARCHAR(MAX))

 --Set the HTML for the body

SET @body ='<html><body><H3>Dossier Info</H3>
<table border = 1> 
<tr>
<th> col1 </th> <th> col2 </th> <th> col3 </th> <th> col4 </th></tr>'

 --Stitch everything together, appending the HTML table

SET @body = @body + @xml +'</table></body></html>'

SET NOCOUNT ON 

 --Send the email and append the data table to the body

EXEC dbo.uspSendEmail 'Dossiers FOund', 'aaaaaaaa@aaaa', @body, NULL, 'CC EMAIL 1'
SET NOCOUNT OFF

如果此代码返回COUNT档案：

SET @rows = (SELECT COUNT(*)  
        FROM bo
        WHERE nmdos LIKE '%preço%'
        AND datafinal = DATEADD(day, -1, CONVERT(date, GETDATE()))
        )

然后只需编写所有档案：

...
DECLARE @DossierNames varchar(MAX);
SELECT @DossierNames = STUFF( (
        SELECT ',' + dossierName
        FROM bo
        WHERE nmdos LIKE '%preço%'
        AND datafinal = DATEADD(day, -1, CONVERT(date, GETDATE()))
        FOR XML PATH('')),
        1, 1,'')

IF @rows IS NOT NULL 
    SET @rows = CONCAT(@rows, ' ', @DossierNames)

...
