Dim txtFName As TextBox = CType(Wizard1.FindControl("txtFName"), TextBox)
Dim txtLName As TextBox = CType(Wizard1.FindControl("txtLName"), TextBox)
Dim MyDbConnection As New SqlConnection(ConfigurationManager.ConnectionStrings.Item("Journeyeast Connection String").ToString)
MyDbConnection.Open()
Dim SQL = "INSERT INTO Registration(FName, LName) VALUES (@FName, @LName)"
Dim MySqlCommand As New SqlCommand(SQL, MyDbConnection)
MySqlCommand.Parameters.Add("@FName", SqlDbType.NChar, 10, txtFName.Text)
MySqlCommand.Parameters.Add("@LName", SqlDbType.NChar, 10, txtLName.Text)
MySqlCommand.ExecuteNonQuery()
我收到以下错误:
参数化查询'(@ FName nchar(10),@ LName nchar(10))INSERT INTO Registration(FNam'期望参数'@FName',未提供。
我做错了什么?
BTW,我知道nchar(10)
不是名字和姓氏的好选择。
答案 0 :(得分:3)
因为您没有提供参数值。
看看:
Dim SQL = "INSERT INTO Registration(FName, LName) VALUES (@FName, @LName)"
Dim MySqlCommand As New SqlCommand(SQL, MyDbConnection)
MySqlCommand.Parameters.AddWithValue("@FName",txtFName.Text)
MySqlCommand.Parameters.AddWithValue("@LName",txtLName.Text)
MySqlCommand.ExecuteNonQuery()
编辑:
MySqlCommand.Parameters.Add("@FName", SqlDbType.NChar, 10).Value = txtFname.Text
MySqlCommand.Parameters.Add("@LName", SqlDbType.NChar, 10).Value = txtFname.Text
