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;UID=sa;PWD=sa]"
' 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
