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
