　　将表数据生成SQL脚本的存储过程:

CREATE PROCEDURE dbo.UspOutputData
@tablename sysname
AS
declare @column varchar(1000)
declare @columndata varchar(1000)
declare @sql varchar(4000)
declare @xtype tinyint
declare @name sysname
declare @objectId int
declare @objectname sysname
declare @ident int

set nocount on
set @objectId=object_id(@tablename)

if @objectId is null -- 判斷對象是否存在
begin
print @#The object not exists@#
return
end
set @objectname=rtrim(object_name(@objectId))

if @objectname is null or charindex(@objectname,@tablename)=0 --此判断不严密
begin
print @#object not in current database@#
return
end

if OBJECTPROPERTY(@objectId,@#IsTable@#) < > 1 -- 判斷對象是否是table
begin
print @#The object is not table@#
return
end

select @ident=status&0x80 from syscolumns where id=@objectid and status&0x80=0x80

if @ident is not null
print @#SET IDENTITY_INSERT @#+@TableName+@# ON@#

declare syscolumns_cursor cursor

for select c.name,c.xtype from syscolumns c where c.id=@objectid order by c.colid

open syscolumns_cursor
set @column=@#@#
set @columndata=@#@#
fetch next from syscolumns_cursor into @name,@xtype

while @@fetch_status < >-1
begin
if @@fetch_status < >-2
begin
if @xtype not in(189,34,35,99,98) --timestamp不需处理，image,text,ntext,sql_variant 暂时不处理

begin
set @column=@column+case when len(@column)=0 then@#@# else @#,@#end+@name

set @columndata=@columndata+case when len(@columndata)=0 then @#@# else @#,@#@#,@#@#,@#
end

+case when @xtype in(167,175) then @#@#@#@#@#@#@#@#@#+@#+@name+@#+@#@#@#@#@#@#@#@#@# --varchar,char

else @name end

end

end

fetch next from syscolumns_cursor into @name,@xtype

end

close syscolumns_cursor
deallocate syscolumns_cursor

set @sql=@#set nocount on select @#@#insert @#+@tablename+@#(@#+@column+@#) values(@#@#as @#@#--@#@#,@#+@columndata+@#,@#@#)@#@# from @#+@tablename

print @#--@#+@sql
exec(@sql)

if @ident is not null
print @#SET IDENTITY_INSERT @#+@TableName+@# OFF@#

GO

exec UspOutputData 你的表名
