1． 定义连接对象

Global DBconnect As New ADODB.Connection

2． 执行连接语句

If DBconnect.State = adStateOpen And Not IsEmpty(adStateOpen) Then DBconnect.Close

l         连接ODBC

    DBconnect.ConnectionString = "dsn=DataAliasName;uid=UserID;pwd=Passwd;"

l         直接连接Access为

Dbconnect.Provider = "Microsoft.jet.OLEDB.4.0"  // Access 97为3.51

DBconnect.ConnectionString = "FilePath\FileName.mdb"

l         连接Oracle

DBconnect.Provider = "MSADORA"

DBconnect.ConnectionString = "user/mypass@servicename

l         连接SQL Server

DBconnect.Provider = "SQLOLEDB.1"

DBconnect.ConnectionString = "DATABASE= ;SERVER= ;UID= ;PWD= ;"

或者可以使用 DBconnect.Open "SERVER" , "USERID" , "PASSWORD"

DBConnect.Open

3． 取查询结果集

Global RS As New ADODB.Recordset

Global PS As New ADODB.Recordset

If RS.State = adStateOpen And Not IsEmpty(adStateOpen) Then RS.Close

     RS.Open SQLStr, DBconnect, adOpenKeyset

4． 执行SQL语句

DBconn.Execute SQLStr

5． 关闭数据库

DBconnect.Close
