asp.net - 如何同时更新两个表中的字段

Question

我必须在 Access 数据库中添加标签

用户

• 用户ID
• 用户名
• 用户激活

用户信息

• 用户信息
• 用户真实姓名
• 用户电话

然后我从一些 asp:text 字段获取信息到更新处理程序，我知道如何为一个表执行此操作，但不知道如何为 2 个表执行此操作。

通常我用这个

    Dim strSQL As String = ""
    strSQL = "" & _
    "UPDATE Userinfo " & _
    "SET userrealname = @therealname, userphone = @theuserphone " & _
    "WHERE userinfoid =" & Session("theeditid") & ""

    Using connection As OleDbConnection = New OleDbConnection(ConfigurationManager.ConnectionStrings("ConnStr").ConnectionString)
        Using updatecmd As OleDbCommand = New OleDbCommand(strSQL, connection)
            updatecmd.CommandType = CommandType.Text
            updatecmd.Parameters.AddWithValue("@therealname", OleDbType.VarChar).Value = TextBox1.Text
            updatecmd.Parameters.AddWithValue("@theuserphone", OleDbType.VarChar).Value = CKEditor1.Text
            Try
                updatecmd.Connection.Open()
                Dim i As Integer = CInt(updatecmd.ExecuteNonQuery())
                If i = 0 Then
                    Session("editsucces") = "NoMatch" 'no rows were updated because none matched the criteria
                End If
            Catch ex As Exception
                Session("editsucces") = "DBerror" 'Something went wrong, such as the database was unavailable
            End Try
        End Using
    End Using

所以我现在的问题是，如何添加用户选项卡中的字段!？ user.userid 与 userinfo.userinfoid 中的数字相同。

编辑……编辑……编辑……编辑……编辑……编辑......编辑

所以这段代码没问题，或者你建议我更改其中的一些代码!？

Dim strSQL As String = ""
    strSQL = "" & _
    "UPDATE Users INNER JOIN Userinfo ON Users.UserID = Userinfo.UserID " & _
    "SET Users.Username = [@uname], Users.Password = [@upass], Users.UserActiv = [@uactiv], Userinfo.UserRealName = [@urname], Userinfo.UserEmail1 = [@umail], Userinfo.UserDOB = [@udob], Userinfo.UserPhone1 = [@uphone1], Userinfo.UserPhone2 = [@uphone2], Userinfo.UserPhone3 = [@uphone3], Userinfo.UserYear = [@uyear], Userinfo.UserSick = [@usick] " & _
    "WHERE Users.UserID = [@uid]"

    Using connection As OleDbConnection = New OleDbConnection(ConfigurationManager.ConnectionStrings("ConnStr").ConnectionString)
        Using updatecmd As OleDbCommand = New OleDbCommand(strSQL, connection)
            updatecmd.CommandType = CommandType.Text
            updatecmd.Parameters.AddWithValue("@uname", OleDbType.VarChar).Value = userinput1.Text
            updatecmd.Parameters.AddWithValue("@upass", OleDbType.VarChar).Value = userinput2.Text
            updatecmd.Parameters.AddWithValue("@uactiv", OleDbType.VarChar).Value = "Y"
            updatecmd.Parameters.AddWithValue("@urname", OleDbType.VarChar).Value = userinput3.Text
            updatecmd.Parameters.AddWithValue("@umail", OleDbType.VarChar).Value = userinput4.Text
            updatecmd.Parameters.AddWithValue("@udob", OleDbType.VarChar).Value = userinput5.Text
            updatecmd.Parameters.AddWithValue("@uphone1", OleDbType.VarChar).Value = userinput6.Text
            updatecmd.Parameters.AddWithValue("@uphone2", OleDbType.VarChar).Value = userinput7.Text
            updatecmd.Parameters.AddWithValue("@uphone3", OleDbType.VarChar).Value = userinput8.Text
            updatecmd.Parameters.AddWithValue("@uyear", OleDbType.VarChar).Value = userinput9.Text
            updatecmd.Parameters.AddWithValue("@usick", OleDbType.VarChar).Value = usertextarea.Text
            Try
                updatecmd.Connection.Open()
                Dim i As Integer = CInt(updatecmd.ExecuteNonQuery())
                If i = 0 Then
                    Session("editsucces") = "NoMatch" 'no rows were updated because none matched the criteria
                End If
            Catch ex As Exception
                Session("editsucces") = "DBerror" 'Something went wrong, such as the database was unavailable
            End Try
        End Using
    End Using

应该可以创建一个联接来更新两个表。例如:

sSQL = "UPDATE [User] INNER JOIN userinfo " _
& "ON User.UserID = userinfo.userinfoid SET " _
& "[User].UserName = [uname], userinfo.userrealname = [urname] " _
& "WHERE [User].UserID = [uid]"

cmd.ActiveConnection = cn
cmd.CommandText = sSQL
cmd.CommandType = adCmdText
cmd.Parameters.Append cmd.CreateParameter( _
    "uname", adVarChar, adParamInput, 50, "user name")
cmd.Parameters.Append cmd.CreateParameter( _
    "urname", adVarChar, adParamInput, 50, "user real name")
cmd.Parameters.Append cmd.CreateParameter( _
    "uid", adInteger, adParamInput, , 2)
cmd.Execute
