在VB中，如何连接MYSQL

楼上讲的是VB2005的连接方法，不知道你用的是什么版本的VB,我给你一个VB6.0的连接方法吧

先在本机上安装最新的ODBC CONNECTER/mysql

无需设置ODBC,就可以使用.

注意MYSQL的帐户登录是根据主机的,设置好MYSQL的帐户后再做测试.

测试代码:

Dim conn As ADODB.Connection

Dim rs As ADODB.Recordset

Dim fld As ADODB.Field

Dim sql As String

'connect to MySQL server using MySQL ODBC 3.51 Driver

Set conn = New ADODB.Connection

conn.ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver}" _

&"SERVER=192.168.0.1" _

&" DATABASE=db_name" _

&"UID=usernamePWD=passwordOPTION=3"

conn.Open

'create table

conn.Execute "DROP TABLE IF EXISTS my_ado"

conn.Execute "CREATE TABLE my_ado(id int not null primary key, name varchar(20)," _

&"txt text, dt date, tm time, ts timestamp)"

'direct insert

conn.Execute "INSERT INTO my_ado(id,name,txt) values(1,100,'venu')"

conn.Execute "INSERT INTO my_ado(id,name,txt) values(2,200,'MySQL')"

conn.Execute "INSERT INTO my_ado(id,name,txt) values(3,300,'Delete')"

Set rs = New ADODB.Recordset

rs.CursorLocation = adUseServer

'fetch the initial table ..

rs.Open "SELECT * FROM my_ado", conn

Debug.Print rs.RecordCount

rs.MoveFirst

Debug.Print String(50, "-") &"Initial my_ado Result Set " &String(50, "-")

For Each fld In rs.Fields

Debug.Print fld.name,

Next

Debug.Print

Do Until rs.EOF

For Each fld In rs.Fields

Debug.Print fld.value,

Next

rs.MoveNext

Debug.Print

Loop

rs.Close

conn.Close

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。。。
