从SQLServer 导入/导出 Excel 的方法
最近在晚上看了一篇文章（从SQLServer 导入/导出 Excel 的方法 ）： 但是把源码拷贝过来后 出现很多错误 改了好久也没亚成功！ 不知道那位高人 能帮忙看看 并帮忙测试一下后 把源码贴出来供小弟看看 也好给大家分享一下！

下面是 网络源码：


create proc p_exporttb

declare @obj int,@constr nvarchar(1000),@sql varchar(8000),@fdlist varchar(8000)

--参数检测

set @constr=’DRIVER={Microsoft Excel Driver (*.xls)};DSN=’’’’;READONLY=FALSE’

--连接数据库

if @err〈〉0 goto lberr

exec @err=sp_oamethod @obj,’open’,null,@constr

[解决办法]
作 用:把sql语句查询出的结果导到Excel中包含字段名称
Create By:Hchuan
Script Date:2006-08-30

执行示例:

declare @sql varchar(8000)
set @sql = 'select top 100 percent * from ptype order by typeid '
Exec H_SqlToExcel 'f:\ ', '商品档案.xls ', '商品档案 ',@sql

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

CREATE PROC H_SqlToExcel

@SheetName varchar(80),---工作表名字
@SqlStr varchar(8000)--查询语句,如果查询语句中使用了order by ,请加上top 100 percent,注意,如果导出表/视图,用上面的存储过程
