【中文标题】生成 HTML 响应的存储过程不起作用【英文标题】：Stored procedure to generate HTML response doesnot work 【发布时间】：2022-01-08 09:40:26 【问题描述】：我正在尝试从存储过程中获取 html，以便可以在我的 SSIS 包中使用此存储过程来发送带有此正文的电子邮件。
这是 SQL 查询：
SELECT
cus.CustomerNumber AS CustomerNumber,
cus.Location AS ReceivingLocation,
i.StrainName AS StrainName, i.StrainCode AS StrainCode,
i.Age AS Age, i.Sex AS Sex,
i.Genotype AS Genotype, i.RoomNumber AS SentFrom,
io.OrderQuantity AS OrderQuantity
FROM
[dbo].[MouseOrder] mo
JOIN
[dbo].[Customer] cus ON cus.Customer_ID = mo.CustomerId
JOIN
[dbo].[InventoryOrder] io ON io.OrderId = mo.MouseOrder_ID
JOIN
[dbo].[Inventory] i ON i.Inventory_ID = io.InventoryId
WHERE
mo.OrderDate = CONVERT(date, GETDATE() AT TIME ZONE 'UTC' AT TIME ZONE 'Eastern Standard Time')
AND mo.SAMAccountEmail = 'abc.def@inc.org'
我尝试将其作为存储过程执行，以便它可以生成 HTML 响应
CREATE PROCEDURE GenerateEmailBody
AS
BEGIN
DECLARE @xhtmlBody XML,
@body NVARCHAR(MAX),
@tableCaption VARCHAR(30) = 'Orderlist';
SET @xhtmlBody = (SELECT (
SELECT cus.CustomerNumber as CustomerNumber,cus.Location as ReceivingLocation,
i.StrainName as StrainName,i.StrainCode as StrainCode,i.Age as Age,
i.Sex as Sex,i.Genotype as Genotype,i.RoomNumber as SentFrom,io.OrderQuantity as OrderQuantity
FROM [dbo].[MouseOrder] mo
JOIN [dbo].[Customer] cus on cus.Customer_ID = mo.CustomerId
JOIN [dbo].[InventoryOrder] io on io.OrderId = mo.MouseOrder_ID
JOIN [dbo].[Inventory] i on i.Inventory_ID = io.InventoryId
WHERE mo.OrderDate = convert(date,getdate() AT TIME ZONE 'UTC' AT TIME ZONE 'Eastern Standard Time') and mo.SAMAccountEmail = 'abc.def@inc.org'
FOR XML PATH('row'), TYPE, ROOT('root'))
.query('<html><head>
<meta charset="utf-8"/>
(: including embedded CSS styling :)
<style>
table <![CDATA[ border-collapse: collapse; width: 300px; ]]>
th <![CDATA[ background-color: #4CAF50; color: white; ]]>
th, td <![CDATA[ text-align: left; padding: 8px; ]]>
tr:nth-child(even) <![CDATA[ background-color: #f2f2f2; ]]>
#green <![CDATA[ background-color: lightgreen; ]]>
</style>
</head>
<body>
<table border="1">
<caption><h2>sql:variable("@tableCaption")</h2></caption>
<thead>
<tr>
<th>Cust Numb</th>
<th>Rec Location</th>
<th>Strain</th>
<th>Strain Code</th>
<th>Age</th>
<th>Sex</th>
<th>Genotype</th>
<th>Sent From</th>
<th>Order Quantity</th>
</tr>
</thead>
<tbody>
for $row in /root/row
return <tr>
<td>data($row/CustomerNumber)</td>
<td>data($row/ReceivingLocation)</td>
<td>data($row/StrainName)</td>
<td>data($row/StrainCode)</td>
<td>data($row/Age)</td>
<td>data($row/Sex)</td>
<td>data($row/Genotype)</td>
<td>data($row/SentFrom)</td>
<td>data($row/OrderQuantity)</td>
</tr>
</tbody></table></body></html>'));
SELECT @xhtmlBody;
SET @body = CAST(@xhtmlBody AS NVARCHAR(MAX));
END
GO
当我尝试执行存储过程时，它返回 int，如下所示：
这是我第一次尝试存储过程 - 我不确定我错过了什么 - 非常感谢任何帮助
******编辑******
执行 SQL 任务
Scipt 如下所示
namespace ST_c2e68b3edd6842c4a6554376987c97c1
[Microsoft.SqlServer.Dts.Tasks.ScriptTask.SSISScriptTaskEntryPointAttribute]
public partial class ScriptMain : Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase
enum ScriptResults
Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success,
Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
public void Main()
string data = Dts.Variables["User::EmailData"].Value.ToString();
SendEmail(data);
Dts.TaskResult = (int)ScriptResults.Success;
private void SendEmail(string messageBody)
ConnectionManager smtpConnectionManager = Dts.Connections["SMTP Connection Manager"];
SmtpClient emailClient = new SmtpClient(smtpConnectionManager.Properties["SmtpServer"].GetValue(smtpConnectionManager).ToString());
MailMessage email = new MailMessage();
email.Priority = MailPriority.Normal;
email.IsBodyHtml = true;
email.From = new MailAddress("abc.def@inc.org");
email.To.Add("abc.def@inc.org");
email.Body = messageBody;
emailClient.Send(email);
它会抛出类似的错误
Error: 0xC002F210 at Execute SQL Task, Execute SQL Task: Executing the query "EXEC dbo.GenerateEmailBody ?" failed with the following error: "Parameter name is unrecognized.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. Task failed: Execute SQL Task
【问题讨论】：
那是因为存储过程只会返回一个整数。它用于指示执行的状态。您需要使用 OUTPUT 参数来保存您在此处尝试的数据。 您的存储过程正在运行。 ？？？您需要按如下方式启动：EXEC dbo.GenerateEmailBody
@YitzhakKhabinsky 如何在 where 子句中参数化这个 mo.SAMAccountEmail 以便我可以将值动态传递给 SP
【参考方案1】：
假设您想要@body，您可以将其设为输出参数：
CREATE PROCEDURE GenerateEmailBody (@body NVARCHAR(MAX) OUTPUT)
AS
BEGIN
DECLARE @xhtmlBody XML
, @tableCaption VARCHAR(30) = 'Orderlist';
...
然后这样称呼它：
DECLARE @return_value int
DECLARE @html NVARCHAR(MAX)
exec @return_value = [dbo].[GenerateEmailBody] @html OUTPUT
select @html
【讨论】：
【参考方案2】：如下：
SQL
CREATE PROCEDURE dbo.usp_GenerateEmailBody
(
@SAMAccountEmail VARCHAR(100)
)
AS
BEGIN
...
... and mo.SAMAccountEmail = @SAMAccountEmail -- usage of the SP parameter

非常感谢您耐心地帮助我让这件事正常工作。非常感谢。我再次陷入困境。我已经编辑了现在失败的问题 @对不起，我在办公室无法连接以上是关于生成 HTML 响应的存储过程不起作用的主要内容，如果未能解决你的问题，请参考以下文章
