能否将表中的数据备份成一条条insert into 的语句？

当然可以！！！以下是源代码！！！！


use database_name
go
--输入表名，生成插入语句
if Exists( select name from sysobjects  where name= \'proc_insert\' and type=\'p\')
drop procedure proc_insert
go
create proc proc_insert (@tablename varchar(256))
as
begin
set nocount on
declare @sqlstr varchar(4000)
declare @sqlstr1 varchar(4000)

select @sqlstr1=\'\'
select @sqlstr2=\' (\'
select @sqlstr1= \' values ( \'\'+\'
select @sqlstr1=@sqlstr1+col+\'+\'\',\'\'+\' ,@sqlstr2=@sqlstr2+name +\',\' from (select case

exec( @sqlstr)
set nocount off
end
go

在查询分析器中执行

Exec Proc_insert  table_name
讲显示出Insert 语句。
