VB6.0使用ADO對象連接數據庫

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Aclearcase/" target="_blank" >ccess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
