Question

我遇到麻烦我似乎无法使我的SQL查询正确

                Dim command1 As New MySqlCommand("UPDATE userscanner SET Username ='" & txtbox_username.Text & "',Password='" & txtbox_password.Text & "' WHERE ID = '" & lbl_id.Text & "')", Connection)
                command1.ExecuteNonQuery()
                MsgBox("Profile Successfuly Saved")
                Me.Close()

但我有错误说＆＃34;你的sql语法有错误;查看适用于您的MySQL服务器版本的手册，以获得正确的语法，以便在附近使用＆＃39;）＆＃39;在第1行

BTW我使用XAMPP和MYSQL作为数据库

Answer 1

试试这个：

        Dim command1 As New MySqlCommand("UPDATE userscanner SET Username ='" & txtbox_username.Text & "',Password='" & txtbox_password.Text & "' WHERE ID = '" & lbl_id.Text & "'", Connection)
        command1.ExecuteNonQuery()
        MsgBox("Profile Successfuly Saved")
        Me.Close()

Answer 2

你似乎包括了一个＆＃39;）＆＃39;在构造sql语句时关闭没有开头的paranthesis

Answer 3

我认为你需要删除'）'。

Dim command1 As New MySqlCommand("UPDATE userscanner SET Username ='" & txtbox_username.Text & "',Password='" & txtbox_password.Text & "' WHERE ID = '" & lbl_id.Text & "'", Connection)

Answer 4

你有多余的＆＃39;）＆＃39;

校正：

            Dim command1 As New MySqlCommand("UPDATE userscanner SET Username ='" & txtbox_username.Text & "',Password='" & txtbox_password.Text & "' WHERE ID = '" & lbl_id.Text & "'", Connection)
            command1.ExecuteNonQuery()
            MsgBox("Profile Successfuly Saved")
            Me.Close()

Answer 5

您应该使用参数化更新查询
