求VB.NET2010连接MDB数据库后，添加、修改和删除等写法示例

引用 Microsoft ActiveX Data Objects 2.8 Library

或者加入microsoft ado data control

定义数据库连接

Dim Cnn As New ADODB.Connection

定义 *** 作记录

Dim Res As New ADODB.Recordset

开始使用

If Res.State = 1 Then Res.Close

Res.CursorLocation = adUseClient

Res.Open "SELECT * From 发票表", Cnn, adOpenDynamic, adLockReadOnly

删除用res.Delete

添加用res.AddNew

res.Fields("序号") = Trim(Res.Fields("序号"))

...

res.Update

更新用Res.Update "序号", 111

列：

'写入产品信息

Sub WriteFP()

'On Error Resume Next

Dim SyBaseRes As New ADODB.Recordset

PB.value = 0

Res.Open "SELECT Count(*) From ICSaleEntry INNER JOIN t_Item ON ICSaleEntry.FItemID = t_Item.FItemID INNER JOIN t_MeasureUnit ON ICSaleEntry.FUnitID = t_MeasureUnit.FMeasureUnitID", SQLServer, adOpenDynamic, adLockReadOnly

Text2.Text = "当前共 " &Val(Res.Fields(0)) &"条数据"

PB.Max = Val(Res.Fields(0))

If Res.State = 1 Then Res.Close

Res.Open "SELECT ICSaleEntry.FDetailID AS 序号,ICSaleEntry.FInterID AS 物料编号, t_Item.FName AS 产品名称,ICSaleEntry.FAuxPrice AS 单价, ICSaleEntry.FAuxQty AS 数量,ICSaleEntry.FAmount AS 原币, ICSaleEntry.FStdAmount AS 本币,t_MeasureUnit.FName AS 单位 FROM ICSaleEntry INNER JOIN t_Item ON ICSaleEntry.FItemID = t_Item.FItemID INNER JOIN t_MeasureUnit ON ICSaleEntry.FUnitID = t_MeasureUnit.FMeasureUnitID", SQLServer, adOpenDynamic, adLockReadOnly

Do While Not Res.EOF

If SyBaseRes.State = 1 Then SyBaseRes.Close

SyBaseRes.Open "select * from 物料表 where 序号='" &Res.Fields("序号") &"'", Cnn, adOpenDynamic, adLockOptimistic

If SyBaseRes.EOF Then

Text2.Text = Text2.Text + vbCrLf + "正在添加: " &Trim(Res.Fields("序号"))

SyBaseRes.AddNew

SyBaseRes.Fields("序号") = Trim(Res.Fields("序号"))

SyBaseRes.Fields("产品编号") = Trim(Res.Fields("物料编号"))

SyBaseRes.Fields("产品名称") = Trim(Res.Fields("产品名称"))

SyBaseRes.Fields("单价") = Trim(Res.Fields("单价"))

SyBaseRes.Fields("数量") = Trim(Res.Fields("数量"))

SyBaseRes.Fields("原币") = Trim(Res.Fields("原币"))

SyBaseRes.Fields("本币") = Trim(Res.Fields("本币"))

SyBaseRes.Fields("单位") = Trim(Res.Fields("单位"))

SyBaseRes.Fields("数据库名") = Trim(Text1.Text)

SyBaseRes.Update

Else

Text2.Text = Text2.Text + vbCrLf + "正在更新: " &Trim(Res.Fields("序号"))

SyBaseRes.Update "序号", Trim(Res.Fields("序号"))

SyBaseRes.Update "产品编号", Trim(Res.Fields("物料编号"))

SyBaseRes.Update "产品名称", Trim(Res.Fields("产品名称"))

SyBaseRes.Update "单价", Trim(Res.Fields("单价"))

SyBaseRes.Update "数量", Trim(Res.Fields("数量"))

SyBaseRes.Update "原币", Trim(Res.Fields("原币"))

SyBaseRes.Update "本币", Trim(Res.Fields("本币"))

SyBaseRes.Update "单位", Trim(Res.Fields("单位"))

SyBaseRes.Update "数据库名", Trim(Text1.Text)

End If

PB.value = PB.value + 1

Res.MoveNext

DoEvents

Loop

If SyBaseRes.State = 1 Then SyBaseRes.Close

Set SyBaseRes = Nothing

End Sub

网络希望不要用ACCESS用ASA（就是sybase那个太强了）

Dim OraSession As Object '会话对象

Dim OraDatabase As Object '数据库对象

Dim OraDynaset As Object'动态集对象

Dim OraDatabase As Object’字段集对象

Set OraSession =CreateObject("OracleInProcServer.XOraSession")

Set OraDatabase=OraSession.CreateDatabase

("Demo","scott/tiger",0&)'建立数据库连接

Set OraDynaset=OraDatabase.CreateDynaset("select*from

student",0&)'初始化动态集对象

’添加记录

'Begin an AddNew

OraDynaset.DbAddNew

OraDynaset.Fields("ID").value="1000"

’ID为列名

OraDynaset.DbUpdate'更新数据到表

’删除

OraDynaset.DbDelete

'修改

OraDynaset.DbEdit

OraDynaset.Fields("ID").value="101210"

OraDynaset.DbUpdate
