1.vb.net利用Oracle.DataAccess.dll链接Oracle数据库
a.安装客户端的情况下引用:
引用oracle安装目录下
product/11.2.0/client_1/ODP.NET/bin/2.x/Oracle.DataAccess.dll
b.直接安装了oracle到本机的话在
D:\oracle\product\10.2.0\db_1\BIN下
c.数据库链接以及操作代码
Private Function dbconnect() As Boolean
Dim strConn = "Data Source=192.168.1.110/orcl;User ID=test;Password=orcl"
Dim dbcmd As OracleCommand
Dim dt = New DataTable("ds")
Dim dbConnection As OracleConnection
Try
dbConnection = New OracleConnection(strConn)
dbConnection.Open()
dbcmd = dbConnection.CreateCommand
dbcmd.CommandText = "select * from student"
Dim da As OracleDataAdapter = New OracleDataAdapter(dbcmd)
da.Fill(dt)
DataGridView1.DataSource = dt '这时候可以把dt的值直接赋值给
DataGridview1控件
Catch ex As Exception
Exit Function
End Try
End Function
