  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
when @xtype in(231,239) then '''N'''''' ' @name ' ''''''''' --nvarchar,nchar
when @xtype=61 then ''''''''' convert(char(23),' @name ',121) ''''''''' --datetime
when @xtype=58 then ''''''''' convert(char(16),' @name ',120) ''''''''' --smalldatetime
when @xtype=36 then ''''''''' convert(char(36),' @name ') ''''''''' --uniqueidentifier
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
