把excel中的数据导入SQL SERVER数据库（access数据类似）：

Private Sub Command1_Click()

Dim strconn As String ' 定义Excel 连接字符串

Dim cn As ADODB.Connection ' 定义Excel 连接

Set cn = New ADODB.Connection

' 初始化commandialog1 的属性，选取Excel 文件，文

' 件名保存在CommanDialog1.filename 中备用

CommonDialog1.Filter = " 电子表格文件(.xls) |*.xls"

CommonDialog1.DialogTitle = " 请选择要导入的文件"

CommonDialog1.ShowOpen

' 设置连接SQL 数据库的连接字符串

strtemp = " [odbc;Driver= {SQL Server} ;Server=(local);Database=Afws;U

' 设置Excel 数据连接

strconn = " Provider =Microsoft.Jet.OLEDB.4.0;Data Source=" & CommonDialog1.FileName & " ; Extended Properties=Excel 8.0"

cn.Open strconn

strSql = "insert into " & strtemp & ".hw_level1 select * from [sheet1$]"

cn.Execute strSql, lngRecsAff, adExecuteNoRecords

MsgBox " 成功导入到SQL 数据库中！", vbExclamation + vbOKOnly

cn.Close

Set cn = Nothing

End Sub

从access数据库中导出数据到为excel（sql数据库类似）：

dim conn as adodb.connection

Dim rs1 As New ADODB.Recordset

dim sql as string

set conn=new adodb.connection

if conn.state<>0 then conn.close

conn.open "Provider=Microsoft.Jet.OLEDB.4.0;Persist Security Info=False;Data Source=" & App.Path &"\sclsylb.mdb"

sql="SELECT * FROM QS800" 'QS800表你应该很熟悉

if rs1.state<>0 then rs1.close

rs1.cursorlocation=aduserclient

rs1.open sql,conn,1,3

'导出xls表

Dim xlApp As New Excel.Application

Dim xlBook As Excel.Workbook

Dim xlSheet As Excel.Worksheet

Dim xlQuery As Excel.QueryTable

'On Error GoTo OutPutErr

Set xlBook = xlApp.Workbooks().Add

Set xlSheet = xlBook.Worksheets("sheet1")

Set xlQuery = xlSheet.QueryTables.Add(rs1, xlSheet.Range("a1 "))

With xlQuery

.FieldNames = True

.RowNumbers = False

.FillAdjacentFormulas = False

.PreserveFormatting = True

.RefreshOnFileOpen = False

.BackgroundQuery = True

.RefreshStyle = xlInsertDeleteCells

.SavePassword = True

.SaveData = True

.AdjustColumnWidth = True

.RefreshPeriod = 0

.PreserveColumnInfo = True

End With

xlQuery.FieldNames = True

xlQuery.Refresh

cmdlg.Flags = 2

cmdlg.Filter = "EXCEL文档(*.xls)"

cmdlg.ShowSave

If cmdlg.FileName <> "" Then

xlApp.DisplayAlerts = False

xlBook.SaveAs FileName:=cmdlg.FileName

If MsgBox("导出成功,是否打开查看?", vbOKCancel, "导出EXCEL") = vbOK Then

xlApp.Workbooks().Open cmdlg.FileName

xlApp.Visible = True

Else

xlApp.Quit

End If

End If

If xlApp <> Null Then Set xlApp = Nothing

set conn=nothing

set rs1=nothing
