Access（VBA）连接Oracle数据库的代码[亲测有效]

access是包含前台程序开发和后台数据库的应用软件。

可以利用access作为前台开发，后台用sqlServer，oracle这些作为数据库。

而access连接数据库，可以利用链接表。直接读取表记录。也可以通过ADO等数据操作方式读取数据库

方法1:odbc连接方式

 Dim OracleDatabase As String
 OracleDatabase = "DSN=ODBC源名称;UID=你的用户名;PWD=你的密码;LANGUAGE=us_english; DATABASE=NOKIAKPI"
 Set conn = CreateObject("adodb.connection")
 conn.Open OracleDatabase
 If Err.Number <> 0 Then
 MsgBox ("Please Check connection to KPI Server!")
 DoCmd.Quit
 Else 
 KPITableName = "TEMPKB" & Format(Date, "ddhh24") & Format(Time, "hhss")
 LocalTable = rstrDesTbl
 '----------fetch table from oracle db-------------------
 SQL = "create table " & KPITableName & " as " & rstrSrcTbl 'nokiaadmin
 conn.CommandTimeout = 300
 conn.Execute (SQL)
 DoCmd.DeleteObject acTable, LocalTable
 ' KPITableName = "kpiview." & KPITableName
 DoCmd.TransferDatabase acTable, "ODBC Database", "ODBC;" & OracleDatabase, acTable, KPITableName, LocalTable
 conn.Execute ("DROP TABLE " & KPITableName & ";")
 End If
 Exit Function

方法2：oledb

欢迎大家来到IT世界,在知识的湖畔探索吧!Dim Cnn As Object
 Set Cnn = CreateObject("ADODB.Connection")
 Set rs = CreateObject("ADODB.recordset")
 rs.cursorlocation = 3
 cnn.Open "data source=服务器名;provider=OraOLEDB.Oracle;user id=用户;password=密码"
 Sql = "Select 字段名 from 表名 where ID=1"
 rs.Open SQL, Cnn
 rs.Close
 Set Cnn = Nothing
 Set rs = Nothing
