在 MS Access 2003 中插入​​用户表时出现语法错误

Question

使用带有 ASP.NET 和 ms-access 2003 数据的 VB.NET，我正在尝试将数据从 Web 表单输入到 db.mdb 中名为“USER”的表中。

我试过这段代码：

 Protected Sub btnCreateAccount_Click(sender As Object, e As System.EventArgs) Handles btnCreateAccount.Click

    Dim conn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\Brian\Documents\Visual Studio 2010\WebSites\WebSite3\db.mdb;User Id=admin;Password=;")

    Dim cmd As OleDbCommand = New OleDbCommand("INSERT INTO USER (Name, Surname, Username, Country, TelNo, Password, Address) VALUES (?, ?, ?, ?, ?, ?, ?)", conn)

    If txtPass.Text = txtCPass.Text Then

        cmd.Parameters.Add("@Name", OleDbType.VarChar, 255).Value = txtName.Text
        cmd.Parameters.Add("@Surame", OleDbType.VarChar, 255).Value = txtSurname.Text
        cmd.Parameters.Add("@Address", OleDbType.VarChar, 255).Value = txtAddress.Text
        cmd.Parameters.Add("@Country", OleDbType.VarChar, 255).Value = txtCountry.Text
        cmd.Parameters.Add("@Username", OleDbType.VarChar, 255).Value = txtUsername.Text
        cmd.Parameters.Add("@Password", OleDbType.VarChar, 255).Value = txtPass.Text
        cmd.Parameters.Add("@TelNo", OleDbType.Integer).Value = txtTelNo.Text

        Try

            conn.Open()
            cmd.ExecuteNonQuery()
            conn.Close()

        Catch ex As OdbcException
            Throw ex
        Finally
            conn.Close()
            lblAccount.Visible = True


        End Try

    End If

End Sub

但它给我返回了一条错误消息：

对可能导致问题的原因有何建议？

Answer 1

User 和 Password 是保留关键字。更改名称，或在查询中的名称周围使用方括号：

    Dim cmd As OleDbCommand = New OleDbCommand("INSERT INTO [USER] (Name, Surname, Username, Country, TelNo, [Password], Address) VALUES (?, ?, ?, ?, ?, ?, ?)", conn)

---

那么，接下来你会遇到的错误：由于参数没有在查询中命名，Parameters集合中的参数对象必须按照它们在查询中使用的顺序添加。
