复制某表的部分字段到新表 vb vb.net

说实话你这个题目不是很明确

让我有点不明白你想要的代码是什么

那么我的理解就是

你现在有两个表,表1,表2

你选中表1的某行,然后把选中的这行添加到表2去

如果是这样的话那么做法就是

运行环境 VB2008(.NET)

假设窗体名称为Form1,你添加六个控件出来

表格控件DataGridView1,DataGridView2

按扭控件四个Button1,Button2,Button3,Button4

然后清空窗体里所有代码使用我的代码就行了

Imports System.Data.OleDb

Public Class Form1

Public LeafFileName As String = CurDir() "\Access.mdb" '这里是数据库文件路径和名称,你自己改

Public LeafFormName As String = "projects" '这里是你要读取这个数据库内的表的名称

Public LeafPassWord As String = "leafsoftpassword" '这里是数据库密码,如果没有密码就随便

Public LeafData1 As DataTable

Public LeafData2 As DataTable

Public LeafNewRow As DataRow '本次值得一提的是前两次给你的代码里都有这行,实际上这行在前两次里是没有用的,这行是添加行时需要的一个行的类,我忘记删除掉这个了而已,恰好在这次需要使用了,让你能更好地理解

Dim LeafOleDbConnection As OleDbConnection

Dim LeafOleDbCommand As OleDbCommand

Dim LeafOleDbDataAdapter As OleDbDataAdapter

Dim LeafCommandBuilder As OleDbCommandBuilder

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Button1.Text = "读取"

Button2.Text = "保存"

Button3.Text = "删除"

Button4.Text = "转移行"

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Try

Dim LeafITemp As Integer

LeafOleDbConnection = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" LeafFileName ";" "Jet OLEDB:Database Password='" LeafPassWord "';")

LeafOleDbDataAdapter = New OleDbDataAdapter("SELECT * FROM " LeafFormName, LeafOleDbConnection)

LeafData1 = New DataTable

LeafData2 = New DataTable

LeafOleDbDataAdapter.Fill(LeafData1)

DataGridView1.DataSource = LeafData1

For LeafITemp = 0 To LeafData1.Columns.Count - 1

LeafData2.Columns.Add(LeafData1.Columns(LeafITemp).ColumnName)

Next

DataGridView2.DataSource = LeafData2

Catch LeafError As Exception

MsgBox("读取数据失败,错误号为:" Err.Number Chr(10) "错误原因是:" LeafError.Message)

End Try

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Save()

End Sub

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

Dim LeafITemp As Integer

Try

For LeafITemp = 0 To LeafData1.Rows.Count - 1

If LeafData1.Rows(LeafITemp).RowState DataRowState.Deleted Then

If LeafData1.Rows(LeafITemp).Item(0) = DataGridView1(0, DataGridView1.CurrentRow.Index).Value Then

LeafData1.Rows(LeafITemp).Delete()

Save()

Exit Sub

End If

End If

Next

MsgBox("找不到要删除的行,可能该行已经不存在.")

Catch LeafError As Exception

MsgBox("删除数据失败,错误号为:" Err.Number Chr(10) "错误原因是:" LeafError.Message)

End Try

End Sub

Sub Save()

LeafOleDbCommand = New OleDbCommand("SELECT * FROM " LeafFormName, LeafOleDbConnection)

LeafOleDbDataAdapter = New OleDbDataAdapter

LeafCommandBuilder = New OleDbCommandBuilder(LeafOleDbDataAdapter)

LeafOleDbCommand.CommandType = CommandType.Text

LeafOleDbDataAdapter.SelectCommand = LeafOleDbCommand

Try

LeafOleDbDataAdapter.Update(LeafData1.GetChanges)

LeafData1.AcceptChanges()

Catch LeafError As Exception

If Microsoft.VisualBasic.Left(LeafError.Message, 5) "值不能为空" Then

MsgBox("保存数据失败,错误号为:" Err.Number Chr(10) "错误原因是:" LeafError.Message)

Else

MsgBox("表内数据并没有更改.")

End If

End Try

End Sub

Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click

Try

Dim LeafITemp As Integer

LeafNewRow = LeafData2.NewRow

For LeafITemp = 0 To LeafData2.Columns.Count - 1

LeafNewRow.Item(LeafITemp) = DataGridView1(LeafITemp, DataGridView1.CurrentRow.Index).Value

Next

LeafData2.Rows.Add(LeafNewRow)

Catch LeafError As Exception

MsgBox("转移行失败,错误号为:" Err.Number Chr(10) "错误原因是:" LeafError.Message)

End Try

End Sub

End Class

VB。NET怎么把一个表的结构到复制到另一个表中

个人觉得：楼主所需要达到的，不应该由。net来实现吧，以下是个人的一些学习笔记，或许可以帮助你，看看吧

SQL语句：select .....into....from

1、从B表中读取数据插入到现有的A表：

insert into A select * from B where 条件；

2、新建一个与A表同样结构的表B，并把A表中满足条件的数据写入表B：

select * into B from A where 条件

3、根据一个表A的数据，来更新表B的字段值（A,B表可以夸库）

update B

set B.字段1 =A.字段1，B.字段2=A.字段2

from A inner join B

on A.条件字段=B.条件字段

VB.NET中如何用SQL语句建表（复制表）？谢谢了！

分类: 电脑/网络 程序设计 其他编程语言

问题描述:

在SQL数据库里已有一个现成的空数据表（只有字段、没有数据），请问高手，怎样在VB.NET中用SQL语句把该数据库中的那个表复制一个到该数据库（字段不变、数据为空）只是把数据表的名改了？

谢谢！谢谢！

解析:

select * into 新表 from 旧表

使用 SELECT INTO 插入行

SELECT INTO 语句创建一个新表，并用 SELECT 的结果集填充该表。新表的结构由选择列表中表达式的特性定义，例如：

SELECT Shippers.*, Link.Address, Link.City,

Link.Region, Link.PostalCode

INTO NewShippers

FROM Shippers

JOIN LinkServer.DB.dbo.Shippers AS Link

ON (Shippers.ShipperID = Link.ShipperID)

SELECT INTO 可将几个表或视图中的数据组合成一个表。也可用于创建一个包含选自链接服务器的数据的新表。
