一般用BCP在处理这个事情，但有时也需要一些特殊的处理，以下是生成表中的一些数据，带有where条件的选择生成数据，是我一个同事修改的，直接拿过来用了：
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS ON
GO
Create Proc proc_insert_where (@tablename varchar(256),@where varchar(256))
as -- 表名称
begin
Declare @sqlstr varchar(8000),
@sqlstr1 varchar(8000),
@sqlstr2 varchar(8000),@col varchar(1000),@colid int,@name varchar(20)
Select @sqlstr='select ''Insert '+@tablename
Select @sqlstr1= ' Values ( ''+', @sqlstr2=' ('
--print '5'
select @where = isnull(@where,'')
Select case
-- when a.xtype =173 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar('+convert(varchar(4),a.length*2+2)+'),'+a.name +')'+' end'
when a.xtype =104 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(1),'+a.name +')'+' end'
when a.xtype =175 then 'case when '+a.name+' is null then ''NULL'' else '+'''''''''+'+'replace('+a.name+','''''''','''''''''''')' + '+'''''''''+' end'
when a.xtype =61 then 'case when '+a.name+' is null then ''NULL'' else '+'''''''''+'+'convert(varchar(23),'+a.name +',121)'+ '+'''''''''+' end'
when a.xtype =106 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar('+convert(varchar(4),a.xprec+2)+'),'+a.name +')'+' end'
when a.xtype =62 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(23),'+a.name +',2)'+' end'
