如何向多个用户发送多个查询

标签: sql vb.net dataset tableadapter

我有一个程序可以通过调度程序自动启动Windows。它的作用是运行查询,然后通过电子邮件发送查询结果。这一切都有效。我想做的是将程序提升到一个新的水平。我们有10个地点。位置DM应每天收到此报告(仅接收其商店)。所以基本上我想要做的是以不同的tableadapter的形式重复代码并通过电子邮件发送该信息。我的C#代码是:

Imports System.Net.Mail
Imports System.Linq

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load


        Try
            Dim SmtpServer As New SmtpClient()
            Dim mail As New MailMessage()
            Me.Paid_Out_TbTableAdapter.Fill(Me.DataSet.Paid_Out_Tb)
            Dim payouts = _
            <html>
                <body>
                    <table border="1">
                        <tr><th>Store #</th><th>Date</th><th>Amount</th><th>User</th><th>Comment</th></tr>
                        <%= From paidOut In Me.DataSet.Paid_Out_Tb.AsEnumerable _
                            Select <tr><td><%= paidOut.Store_Id %></td>
                                       <td><%= Convert.ToDateTime(paidOut.Paid_Out_Datetime).ToString("M/d/yy") %>
                                       </td><td><%= "$" & paidOut.Paid_Out_Amount.ToString("0.00") %></td>
                                       <td><%= paidOut.Update_UserName %></td>
                                       <td><%= paidOut.Paid_Out_Comment %></td></tr> %>
                    </table>
                </body>

            </html>

            If (Me.DataSet.Paid_Out_Tb.Count = 0) Then 'This cheks to see if the dataset is Null.  We do not want to email if the set is Null

                Me.Close()

            Else

                SmtpServer.Credentials = New  _
                Net.NetworkCredential("*****", "****") 'Assign the network credentials
                SmtpServer.Port = 25 'Assign the SMTP Port
                SmtpServer.Host = "10.0.*.*" 'Assign the Server IP
                mail = New MailMessage() 'Starts a mail message
                mail.From = New MailAddress("***@***.com") 'Sets the "FROM" address
                mail.To.Add("****@****.com") 'Sets the "To" address
                'mail.CC.Add("****@****.com") 'set this if you would like to CC
                mail.Subject = "Paid Out Report for 1929"
                mail.IsBodyHtml = True
                mail.Body = payouts.ToString()
                SmtpServer.Send(mail)
                'MsgBox("mail send")
            End If

        Catch ex As Exception

            MsgBox(ex.ToString)


        End Try

我的查询是:

SELECT        Store_Id, Paid_Out_Amount, Paid_Out_Comment, Paid_Out_Datetime, Update_UserName, Till_Number
FROM            Paid_Out_Tb
WHERE        (Store_Id = 1929) AND (Paid_Out_Datetime >= DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)) AND (Paid_Out_Datetime < DATEADD(day, DATEDIFF(day, 0, 
                         GETDATE()), 0)) AND (Paid_Out_Amount > 20) OR
                         (Store_Id = 1929) AND (Paid_Out_Datetime >= DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)) AND (Paid_Out_Datetime < DATEADD(day, DATEDIFF(day, 0, 
                         GETDATE()), 0)) AND (Paid_Out_Comment LIKE N'%' + 'Filter' + '%')

同样,这一切都有效。但我的第二个查询将完全相同,除了我将替换“112”的store_ID。然后,我需要将该查询结果通过电子邮件发送到与1929年ID不同的地址...有关如何最好地完成此任务的任何建议吗?

实现这一目标的最简单方法是添加另一个tableadapter并运行单独的查询...它可能不是最有效的,但对于传输的数据量...它可以工作..
