将表转化成脚本的存储过程

有时候你只需要备份一个表，不需要备份整个数据库，所以执行以下存储过程，将表转化成存储过程：

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 -- 判断对象是否存在
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 -- 判断对象是否是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

 使用方法：exec UspOutputData 你的表名

然后将运行结果存成.sql, 再用SQL SERVER MANAGEMENT STUDIO打开执行就OK了。

转换出来的sql语句，会多几个逗号，所以你要替换掉
