vb如何连接操作MYSQL数据库

必须安装MYSQL的驱动才行,不管是VB还是c++都需要这个驱动。代码如下: Public Function exemysql(ByVal sql As String) As ADODB.Recordset sql = Trim$(sql) Set conn = New ADODB.Connection Set rs = New ADODB.Recordset conn.Open "Driver=MySQL ODBC 3.51 Driver;" _ "Server=服务器地址;" _ "Port=3306;" _ "Database=数据库名;" _ "Uid=用户名;" _ "Pwd=密码" conn.DefaultDatabase = "数据库名" conn.CursorLocation = adUseClient Set rs.ActiveConnection = conn rs.LockType = adLockBatchOptimistic rs.CursorType = adOpenKeyset rs.Open sql Set exesql = rs Set rs = Nothing Set conn = Nothing End Function

vb6.0如何连接MYSQL数据库?

最简单的办法是:在VB里添加一个ADO部件,将其放到窗体中,然后右键选择属性,在其属性页的下面有个生成连接字符串的项,点击其后的按钮,然后一步步的来做(很简单的),然后连接字符串就会在那里生成,只要拷贝这个字符串,就可以用ADODB来连接了。。。

我想用vb操作mysql数据库,可行否

可以的,这个没有问题。

参考:

Option Strict On

Imports MySql.Data.MySqlClient

Module Example

Sub Main()

Dim cs As String = "Database=testdb;Data Source=localhost;" _

"User Id=testuser;Password=test623"

Dim conn As New MySqlConnection(cs)

Try

conn.Open()

Console.WriteLine("MySQL version : {0}", conn.ServerVersion)

Catch ex As MySqlException

Console.WriteLine("Error: " ex.ToString())

Finally

conn.Close()

End Try

End Sub

End Module
