简而言之,我有一个CLR方法,用于从SQL Server向用户发送电子邮件。我在SQL Server表中拥有有关正文,附件,主题,电子邮件等的所有数据信息。好吧,我正在用C#做一个应用程序来执行此操作,我没有遇到有关表中存储过程的保存信息的麻烦,但是当我想执行我的SP发送ID(邮件)时。这说'命令已成功完成'但邮件不发送。然后我测试从SQL Server手动执行我的SP并正确发送一些id和一些不“看”我的发送方法,因为这执行命令正确但做任何事情。为什么会这样?有人在此之前遇到过这个问题吗?
这是我的CLR方法
[SqlProcedure]
public static int CustomMethod(int id_email, out string sError)
{
int mReturn = 0;
DataSet ds = new DataSet();
sError = string.Empty;
Dictionary<int, string> ListFile = new Dictionary<int, string>();
try
{
ds = retornarQuery(strQuery: "ZeusFW_Email_List " + id_email);
if (ds.Tables[0].Rows.Count > 0)
{
for (int i = 0; i <= ds.Tables[0].Rows.Count - 1; i++)
{
DataRow row = ds.Tables[0].Rows[i];
string ds_to_name = (string)row["ds_to_name"];
string ds_to_email = (string)row["ds_to_email"];
string ds_cc_email = (string)row["ds_cc_email"];

string ds_email_xsl = (string)row["ds_email_xsl"];
int in_email_log = (int)row["in_email_log"];
DeliveryNotificationOptions am_notificationoptions = NotificationOptions((int)row["am_notificationoptions"]);
MailPriority am_priority = Priority((int)row["am_priority"]);
if (in_process == 0 && am_email_html == 1)
{
ds_body = DoXSLT(ds_body, ds_email_xsl);
}
ZeusFrameworkSmtp.ZeusFrameworkSmtp email = new ZeusFrameworkSmtp.ZeusFrameworkSmtp();
email.AddFrom = ds_email_user;
email.AddName = ds_email_name;
email.AddTo.Add(ds_to_email);

email.Subject = ds_subject;
email.Body = ds_body;
email.BodyHtml = (am_email_html == 0 ? false : true);
email.Server = ds_email_host;
email.Port = am_email_port;
email.User = ds_email_user;
email.Password = ds_email_password;
email.EnableSsl = (am_email_ssl == 0 ? false : true); ;
email.NotificationOptions = am_notificationoptions;
email.Priority = am_priority;
am_sent_times = am_sent_times + 1;
if (ds.Tables[1].Rows.Count > 0)
{
for (int j = 0; j <= ds.Tables[1].Rows.Count - 1; j++)
{
DataRow rowAttachments = ds.Tables[1].Rows[j];
if (id_email == (int)rowAttachments["id_email"])
{
if ((int)rowAttachments["in_delete_file"] == 1) ListFile.Add(j, (string)rowAttachments["ds_full_path"]);
email.AddAttachments.Add((string)rowAttachments["ds_full_path"]);
}
}
}
bool bresult = email.Send(out sError);
//if (bresult) { mReturn = 1; Database.ZeusFW_Email_Update(id_email, am_sent_times, sError, in_email_log).Run(); }
if (string.IsNullOrEmpty(sError) || sError.Equals("ESTOY EJECUTANDO EL METODO")) sError = "Operación completada con éxito.";
if (ListFile.Count > 0)
{
foreach (KeyValuePair<int, string> item in ListFile)
{
if (item.Key == 1) File.Delete(item.Value.ToString());
}
ListFile.Clear();
}
}
}
else sError = "No se encontró el ID";
}
catch (Exception ex)
{
StringBuilder s = new StringBuilder();
//sError = sError + "-" + "Error executing SQL statement information: " + ex.Message + "id_email : " + id_email.ToString() + "Conn : " + Database.ConnectionString + ex.StackTrace.ToString();
LogWindows _LogWindows = new LogWindows();
_LogWindows.Save("Zeus", sError, System.Diagnostics.EventLogEntryType.Error);
//SqlContext.Pipe.Send("Error executing SQL statement information: " + ex.Message + "id_email> " + id_email_aux.ToString() + "Conn>" + Database.ConnectionString);
}
return mReturn;
}
这是我的存储过程
CREATE PROCEDURE [dbo].[CustomMethod]
@id_email int
,@sError nvarchar(2000)=NULL OUTPUT
WITH EXECUTE AS CALLER
AS
EXTERNAL NAME [AssemblyNamespace].[AssemblyNamespace.AssemblyNamespace1].[CustomMethod]
GO
这两个ID都存在于我的sql表中,就像有效的邮件一样。忽略SP的名称是为了它们在CLR方法和存储过程
中具有相同名称的特权我在SQL Server中遇到此异常。

答案 0 :(得分:3)
以下是一些要注意的事项:
请使用Sql*
类型而不是本机.NET类型作为SQLCLR公共方法的输入和输出参数。签名应该是:
public static SqlInt32 CustomMethod(SqlInt32 id_email, out SqlString sError)
您可以通过.Value
所有的id_email.Value
属性从这些类型中获取原生价值(例如mReturn
)。
您经历了传回状态代码的麻烦,因此捕获它以便您可以看到更多正在发生的事情。在C#代码中,根据bresult
为if (bresult)
{
mReturn = 1;
}
else
{
mReturn = 2;
}
分配一个非零值:
DECLARE @id_email INT,
@sError NVARCHAR(4000),
@return_code INT;
SET @id_email = 37;
EXEC @return_code = dbo.ZeusFW_EmailQueueUnit_SendOutError
@id_email,
@sError OUTPUT;
SELECT @return_code AS [ReturnCode],
N'~' + @sError + N'~' AS [ErrorMessage],
DATALENGTH(@sError) AS [ErrorMessageBytes];
然后将您的T-SQL更改为:
@sError
查看已发布的代码,似乎唯一获取email.Send()
空字符串的方法(它真的是空的吗?)是:
Result
实际上是传回非空白字符串和/或其他不可打印字符的字符串。上面显示的T-SQL已经过调整以检查这一点。其他说明:
mReturn
代替Result
,bResult
代替ErrorMessage
,sError
代替1
。这适用于C#和T-SQL。Count
中减去<=
,因为这会强制您使用<
而不是j < ds.Tables[1].Rows.Count
。使用.mytable tbody tr:nth-child(1) td:nth-child(5) {
/* Styles goes here */
}
在逻辑上是相同的,少一个(不必要的)操作,并且更具可读性: - )。
