1、查詢Excel資料
SELECT *
FROM openrowset('MICROSOFT.JET.OLEDB.4.0',
'Excel 5.0;HDR=YES;DATABASE=c:/aa.xls','select * from [sheet1$]')
SELECT *
FROM OPENDATASOURCE('Microsoft.Jet.OLEDB.4.0',
'Data Source="c:/aa.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...[sheet1$]
2、查詢到的資料導成一個Excel檔案
A.BCP
EXEC master..xp_cmdshell 'bcp 庫名.dbo.表名out c:/Temp.xls -c -q -S"servername" -U"sa" -P""'
參數:S 是SQL伺服器名;U是使用者;P是密碼
B、PROC
/*--資料匯出EXCEL
匯出查詢中的資料到Excel,包含欄位名,檔案為真正的Excel檔案
,如果檔案不存在,將自動建立檔案
,如果表不存在,將自動建立表
基於通用性考慮,僅支援匯出標準資料類型
--鄒建 2003.10--
--flystone 修正當檔案存在時建立失敗的情況
*/
/*--調用樣本
p_exporttb @sqlstr='select * from 地區資料'
,@path='c:/',@fname='aa.xls',@sheetname='地區資料'
--*/
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[sp_exporttb]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure [dbo].[sp_exporttb]
GO
create proc sp_exporttb
@sqlstr varchar(8000),--查詢語句,如果查詢語句中使用了order by ,請加上top 100 percent,注意,如果匯出表/視圖,用上面的預存程序
@path nvarchar(1000),--檔案存放目錄
@fname nvarchar(250),--檔案名稱
@sheetname varchar(250)=''--要建立的工作表名,預設為檔案名稱
as
declare @err int,@src nvarchar(255),@desc nvarchar(255),@out int
declare @obj int,@constr nvarchar(1000),@sql varchar(8000),@fdlist varchar(8000)
--參數檢測
if isnull(@fname,'')=''set @fname='temp.xls'
if isnull(@sheetname,'')='' set @sheetname=replace(@fname,'.','#')
--檢查檔案是否已經存在
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
--資料庫建立語句
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+'"'
--串連資料庫
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
--建立表的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)
if not exists(select 1 from #tb where a=1)
begin
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
end
else
set @fdlist=substring(@fdlist,2,8000)
exec @err=sp_oadestroy @obj
--匯入資料
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 錯誤號碼
,@src as 錯誤源,@desc as 錯誤描述
select @sql,@constr,@fdlist
go
3、往Excel插入資料:
insert into OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
'Data Source="c:/Temp.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...table1 (A1,A2,A3) values (1,2,3)
