SQL SERVER 和EXCEL的数据导入导出

1、在SQL SERVER里查询Excel数据:
-- ======================================================
SELECT * 
FROM OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
'Data Source="c:\book1.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...[Sheet1$]
下面是个查询的示例，它通过用于 Jet 的 OLE DB 提供程序查询 Excel 电子表格。
SELECT * 
FROM OpenDataSource ( 'Microsoft.Jet.OLEDB.4.0',
  'Data Source="c:\Finance\account.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...xactions
-------------------------------------------------------------------------------------------------

2、将Excel的数据导入SQL server :
-- ======================================================
SELECT * into newtable
FROM OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
  'Data Source="c:\book1.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...[Sheet1$]
实例:
SELECT * into newtable
FROM OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
  'Data Source="c:\Finance\account.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...xactions
-------------------------------------------------------------------------------------------------

3、将SQL SERVER中查询到的数据导成一个Excel文件
-- ======================================================
T-SQL代码：
EXEC master..xp_cmdshell 'bcp 库名.dbo.表名out c:\Temp.xls -c -q -S"servername" -U"sa" -P""'
参数：S 是SQL服务器名；U是用户；P是密码
说明：还可以导出文本文件等多种格式
实例:EXEC master..xp_cmdshell 'bcp saletesttmp.dbo.CusAccount out c:\temp1.xls -c -q -S"pmserver" -U"sa" -P"sa"'
EXEC master..xp_cmdshell 'bcp "SELECT au_fname, au_lname FROM pubs..authors ORDER BY au_lname" queryout C:\ authors.xls -c -Sservername -Usa -Ppassword'
在VB6中应用ADO导出EXCEL文件代码： 
Dim cn  As New ADODB.Connection
cn.open "Driver={SQL Server};Server=WEBSVR;DataBase=WebMis;UID=sa;WD=123;"
cn.execute "master..xp_cmdshell 'bcp "SELECT col1, col2 FROM 库名.dbo.表名" queryout E:\DT.xls -c -Sservername -Usa -Ppassword'"
------------------------------------------------------------------------------------------------

4、在SQL SERVER里往Excel插入数据:
-- ======================================================
insert into OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
'Data Source="c:\Temp.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...table1 (A1,A2,A3) values (1,2,3)

T-SQL代码：
INSERT INTO  
OPENDATASOURCE('Microsoft.JET.OLEDB.4.0',  
'Extended Properties=Excel 8.0;Data source=C:\training\inventur.xls')...[Filiale1$]  
(bestand, produkt) VALUES (20, 'Test')
