连接phpmyadmin

Question

任何人都可以帮我解决这个SQL错误吗？ 如何使用xampp将其连接到phpmyadmin中的数据库？ 如果您认为我的代码有问题，请随时更正我的代码。

Imports System.Data.SqlClient
Imports MySql.Data.MySqlClient

Public Class Form1
Dim con As SqlConnection
Dim com As SqlCommand

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
    con = New SqlConnection
    con = New SqlCommand
    con.ConnectionString = "initial catalog=student;user id=sa;pwd="
    con.Open()
    con.Connection = con
End Sub

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
    If TextBox1.Text = " " Or TextBox2.Text = " " Or TextBox3.Text = " " Then
        MsgBox("Please fill all the details")
        Exit Sub
    End If
    com.CommandText = "insert into stud values('" & TextBox1.Text & "','" & TextBox2.Text & "','" & TextBox3.Text & "')"
    com.ExecuteNonQuery()
    MsgBox("1 record is stored successfully")
    TextBox1.Clear()
    TextBox2.Clear()
    TextBox3.Clear()
End Sub
End Class

您应该使用 MySqlConnection ，而不是SqlConnection。 SqlConnection用于SQL Server。它可以从Nuget包下载。
