sql server 带列名导出至excel_数据库技巧

–sql语句就用下面的存储过程

/*–数据导出EXCEL

导出查询中的数据到Excel,包含字段名,文件为真正的Excel文件
,如果文件不存在,将自动创建文件
,如果表不存在,将自动创建表
基于通用性考虑,仅支持导出标准数据类型

/*–调用示例

p_exporttb @sqlstr=select * from 地区资料
,@path=c:\,@fname=aa.xls,@sheetname=地区资料
–*/
if exists (select * from dbo.sysobjects where id = object_id(N[dbo].[p_exporttb]) and OBJECTPROPERTY(id, NIsProcedure) = 1)
drop procedure [dbo].[p_exporttb]
GO

create proc p_exporttb
@sqlstr sysname, –查询语句,如果查询语句中使用了order by ,请加上top 100 percent
@path nvarchar(1000), –文件存放目录
@fname nvarchar(250), –文件名
@sheetname varchar(250)= –要创建的工作表名,默认为文件名
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=temp.xls
if isnull(@sheetname,)= set @sheetname=replace(@fname,.,#)

–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 5.0;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
declare @tbname sysname
set @tbname=##tmp_+convert(varchar(38),newid())
set @sql=select * into [+@tbname+] from(+@sqlstr+) a
exec(@sql)

select @sql=,@fdlist=
select @fdlist=@fdlist+,+a.name
,@sql=@sql+,[+a.name+]
+case when b.name in(char,nchar,varchar,nvarchar) then
text(+cast(case when a.length>255 then 255 else a.length end as varchar)+)
when b.name in(tynyint,int,bigint,tinyint) then int
when b.name in(smalldatetime,datetime) then datetime
when b.name in(money,smallmoney) then money
else b.name end
FROM tempdb..syscolumns a left join tempdb..systypes b on a.xtype=b.xusertype
where b.name not in(image,text,uniqueidentifier,sql_variant,ntext,varbinary,binary,timestamp)
and a.id=(select id from tempdb..sysobjects where name=@tbname)
select @sql=create table [+@sheetname
+](+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 5.0;HDR=YES
;DATABASE=+@path+@fname+,[+@sheetname+$])

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

set @sql=drop table [+@tbname+]
exec(@sql)
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
