1． 定義連接對象

Global DBconnect As New ADODB.Connection

2． 執行連接語句

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

?

l???????? 連接ODBC

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

l???????? 直接連接Access為

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

DBconnect.ConnectionString = "FilePath\FileName.mdb"

l???????? 連接Oracle

DBconnect.Provider = "MSADORA"

DBconnect.ConnectionString = "user/mypass@servicename?

l???????? 連接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． 取查詢結果集

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． 執行SQL語句

DBconn.Execute SQLStr

5． 關閉數據庫

DBconnect.Close
