--第一步：

--启用Ad Hoc Distributed Queries：
exec sp_configure 'show advanced options',1
reconfigure
exec sp_configure 'Ad Hoc Distributed Queries',1
reconfigure
go

--第二步：
    select * from
    OPENROWSET('MICROSOFT.JET.OLEDB.4.0'
    ,'Excel 5.0;HDR=YES;DATABASE=D:\Work\Fiona\Monthly report-Salesman.xls',区域area$)

go

--第三步：
--使用完成后，关闭Ad Hoc Distributed Queries：
exec sp_configure 'Ad Hoc Distributed Queries',0
reconfigure
exec sp_configure 'show advanced options',0
reconfigure  
go

1、在SQL数据库中直接从Excel里面查询数据：
    select * from
    OPENROWSET('MICROSOFT.JET.OLEDB.4.0'
    ,'Excel 5.0;HDR=YES;DATABASE=c:\test.xls',sheet1$)

2、从Excel文件中,导入数据到SQL数据库中,
    select * into 表 from
OPENROWSET('MICROSOFT.JET.OLEDB.4.0'
,'Excel 5.0;HDR=YES;DATABASE=c:\test.xls',sheet1$)

3、从SQL数据库中,导出数据到Excel(excel存在),
    insert into OPENROWSET('MICROSOFT.JET.OLEDB.4.0'
,'Excel 5.0;HDR=YES;DATABASE=c:\test.xls',sheet1$)
select * from 表

4、从SQL数据库中,导出数据到Excel(excel不存在),
    ---- 导出表
    EXEC master..xp_cmdshell 'bcp 数据库名.dbo.表名 out "c: est.xls" /c -/S"服务器名" /U"用户名" -P"密码"'
    ---- 导出查询语句
    EXEC master..xp_cmdshell 'bcp "SELECT au_fname, au_lname FROM pubs..authors ORDER BY au_lname" queryout "c: est.xls" /c -/S"服务器名" /U"用户名" -P"密码"'

5、导入导出的存储过程

--下面是导出真正Excel文件的方法:（请将一下所有代码复制到存储过程中）

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[p_exporttb]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure [dbo].[p_exporttb]
GO

create proc p_exporttb
@tbname sysname,    --要导出的表名
@path nvarchar(1000),   --文件存放目录
@fname nvarchar(250)=''  --文件名,默认为表名
as
declare @err int,@src nvarchar(255),@desc nvarchar(255),@out int
declare @obj int,@constr nvarchar(1000),@sql varchar(8000),@fdlist varchar(8000)

--参数检测
if isnull(@fname,'')='' set @fname=@tbname+'.xls'

--检查文件是否已经存在
if right(@path,1)<>'' set @path=@path+''
create table #tb(a bit,b bit,c bit)
set @sql=@path+@fname
insert into #tb exec master..xp_fileexist @sql

--数据库创建语句
set @sql=@path+@fname
if exists(select 1 from #tb where a=1)
set @constr='DRIVER={Microsoft Excel Driver (*.xls)};DSN='''';READONLY=FALSE'
       +';CREATE_DB="'+@sql+'";DBQ='+@sql
else
set @constr='Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties="Excel 8.0;HDR=YES'
    +';DATABASE='+@sql+'"'

--连接数据库
exec @err=sp_oacreate 'adodb.connection',@obj out
if @err<>0 goto lberr

exec @err=sp_oamethod @obj,'open',null,@constr
if @err<>0 goto lberr

--创建表的SQL
select @sql='',@fdlist=''
select @fdlist=@fdlist+',['+a.name+']'
,@sql=@sql+',['+a.name+'] '
  +case
   when b.name like '%char'
   then case when a.length>255 then 'memo'
    else 'text('+cast(a.length as varchar)+')' end
   when b.name like '%int' or b.name='bit' then 'int'
   when b.name like '%datetime' then 'datetime'
   when b.name like '%money' then 'money'
   when b.name like '%text' then 'memo'
   else b.name end
FROM syscolumns a left join systypes b on a.xtype=b.xusertype
where b.name not in('image','uniqueidentifier','sql_variant','varbinary','binary','timestamp')
and object_id(@tbname)=id
select @sql='create table ['+@tbname
+']('+substring(@sql,2,8000)+')'
,@fdlist=substring(@fdlist,2,8000)
exec @err=sp_oamethod @obj,'execute',@out out,@sql
if @err<>0 goto lberr

exec @err=sp_oadestroy @obj

--导入数据
set @sql='openrowset(''MICROSOFT.JET.OLEDB.4.0'',''Excel 8.0;HDR=YES;IMEX=1
   ;DATABASE='+@path+@fname+''',['+@tbname+'$])'

exec('insert into '+@sql+'('+@fdlist+') select '+@fdlist+' from '+@tbname)

return

lberr:
exec sp_oageterrorinfo 0,@src out,@desc out
lbexit:
select cast(@err as varbinary(4)) as 错误号
  ,@src as 错误源,@desc as 错误描述
select @sql,@constr,@fdlist
go
