Form Declarations Dim mydb As Database Dim mydynaset As Dynaset Private Sub Form_Load() Set mydb=OpenDatabase("",False,False,"ODBC;DSN=Myserver;WSID=LCL;DATABASE=sales") Set mydynaset=mydb CreateDynaset("Select*from Customers")
End Sub 上述例子是以非独占、非只读方式打开sales数据库，并检索Customers表中的所有字段。OpenDatabase函数的最后一个参数是ODBC连接字符串参数，它指明了Microsoft Access连接到SQL Server所需要知道的一些内容。其中“DSN”为数据源名，“WSID”为工作站名，“DATABASE”为所要访问的数据库名。
