**直接执行sql 输出**

SET ANSI_NULLS ON
    GO
    SET QUOTED_IDENTIFIER ON
    GO
     
    declare @tablename sysname 
    declare @column nvarchar(max) 
    declare @columndata nvarchar(max)

    declare @xtype tinyint

    declare @objid int 
    declare @objname sysname 
    declare @ident int 
    
    set @tablename='orderlist'
    	set nocount on 
    	set @objid=object_id(@tablename) 
    
    	if @objid is null -- 判斷對象是否存在 
    	begin 
    		print 'The object not exists' 
    		return 
    	end 
    	set @objname=rtrim(object_name(@objid)) 
    
    	if @objname is null or charindex(@objname,@tablename)=0 
    	begin 
    		print 'object not in current database' 
    		return 
    	end 
    
    	if OBJECTPROPERTY(@objid,'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=@objid and status&0x80=0x80 
    
    	if @ident is not null 
    	begin
    		print 'SET IDENTITY_INSERT '+@TableName+' ON' 
    	end
    
    	declare syscolumns_cursor cursor
    	for select c.name,c.xtype from syscolumns c where c.id=@objid order by c.colid 
    	open syscolumns_cursor

    		begin

在导出表生成脚本时很想把表里面的数据也全部生成脚本，这种感觉不知道大家有木有，反正小编经常这样搞，废话不多说，分享两个方法实现。

1.  利用工具，现在已经是工具的时代，喝茶扯淡分分钟把活干完的快节奏中，你还在埋头苦逼？ `Navicat Premium` 中有对表转储`SQL`的功能如图：  
    ![在这里插入图片描述][2019050623163972.png]
2.  自己编写存储过程实现上述工具内容

Create PROCEDURE OutputData 
    @tablename sysname 
    AS 
    	declare @column nvarchar(max) 
    	declare @columndata nvarchar(max) 
    	declare @sql Nvarchar(max) 
    	declare @xtype tinyint 
    	declare @name sysname 
    	declare @objid int 
    	declare @objname sysname 
    	declare @ident int 
    
    	set nocount on 
    	set @objid=object_id(@tablename) 
    
    	if @objid is null -- 判斷對象是否存在 
    	begin 
    		print 'The object not exists' 
    		return 
    	end 
    	set @objname=rtrim(object_name(@objid)) 
    
    	if @objname is null or charindex(@objname,@tablename)=0 
    	begin 
    		print 'object not in current database' 
    		return 
    	end 
    
    	if OBJECTPROPERTY(@objid,'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=@objid and status&0x80=0x80 
    
    	if @ident is not null 
    	begin
    		print 'SET IDENTITY_INSERT '+@TableName+' ON' 
    	end
    
    	declare syscolumns_cursor cursor
    	for select c.name,c.xtype from syscolumns c where c.id=@objid 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 
    	begin
    		print 'SET IDENTITY_INSERT '+@TableName+' OFF' 
    	end
    
    GO

那么问题来了，如果想要对表部分数据生成插入语句怎么来呢？两个方法进行，  
1 修改存储过程  
2 按照你的条件新建临时表，对临时表执行该存储过程，完美解决，没毛病，洗洗睡觉
