SQL数据库表 与excel 数据导入导出

 1：用select语句将数据库数据导出到excel,可以灵活的用sql语句设计你想要的结果集

declare 
        @server sysname,
    @uname sysname,
    @pwd sysname,
    @QueryText varchar(200), 
        @filename varchar(200) ,
    @hr int,
    @SQlServer int ,
    @result_str varchar(255),
     @QueryResults int,
        @CurrentResultSet int,
        @object int,
        @WorkBooks int,
        @WorkBook int,
        @Range int ,
    @Columns int,
        @Rows int,
        @indColumn int,
        @indRow int,
        @off_Column int,
        @off_Row int,
        @code_str varchar(100)


set @server='cnby\sql2000' 
set @uname='sa'
set @pwd='****'
set @QueryText='SELECT * FROM pubs..authors'
set  @filename ='f:\ImportToExcel.xls'

-- set the server to the local server 
if @server is null set @server=@@servername
--set the username to the current user name
if @uname is null set @uname=system_user 
set nocount on 
 exec @hr=sp_oacreate 'SQLDMO.SQLServer',@SQLServer out
 if @hr<>0 
 begin
    print 'error create SQLDMO.sqlserver'
    return
end
-- connect to the SQL Server 
 if @pwd is null
    begin

    return
    end
else

    if @hr<>0
    begin
    print 'error connect'
    return
    end
end 
--set queryText 
SELECT @result_str = 'ExecuteWithResults("' + @QueryText + '")'

exec @hr=sp_OAMethod @SQLServer,@result_str,@QueryResults out

    PRINT 'error get Rows'
    RETURN
END
 print '@rows'+str(@rows)  --23

EXEC @hr = sp_OACreate 'Excel.Application', @object OUT

BEGIN
    PRINT 'error create Excel.Application'
    RETURN
END

EXEC @hr = sp_OAGetProperty @object, 'WorkBooks', @WorkBooks OUT

    END

    PRINT 'error destroy SQLDMO.SQLServer'
    RETURN
END

2：excel 表导入到数据库表中，不能定义表的结构，而且把第一行当做列了，很郁闷

select * into test(你的数据库表名） from openrowset
('Microsoft.Jet.OLEDB.4.0','Excel 8.0;Database=f:\ImportToExcel.xls', 'select * from [sheet1$]')

[sheet1$]，excel的表名， $符合不能去掉哦，
