<em>EXCEL</em> <em>VBA</em> 如何在不安装or

如果你电脑上的PL/SQL能连上ORACEL数据库，那你的EXCEL就应该能连上，因为你已经安装过oracle客户端了。，连接不上可能是因为你的VBA中的数据库连接参数写的有问题。

Dim cn As New ADODB.Connection '定义数据链接对象e799bee5baa6e78988e69d83332 ，保存连接数据库信息；请先添加ADO引用
Dim rs As New ADODB.Recordset '定义记录集对象，保存数据表
Dim strCn As String, strSQL As String '字符串变量
Dim i As Integer, j As Integer, sht As Worksheet
strCn = "Provider=MSDAORA.1;Password="psw";User ID="userid";Data Source="DB";Persist Security Info=True" strSQL = "select * from tab"
cn.Open strCn
rs.Open strSQL, cn
xrow = 1
Do While (Not rs.EOF)
Sheet1.Cells(xrow, 1) = rs.Fields().Item(0)
....
xrow = xrow + 1
rs .MoveNext
Loop
End Sub
