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’
–*/
create proc p_exporttb
@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
@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

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 8.0;HDR=YES’

–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

exec(@sql)
