SQL Server里面导出SQL脚本(表数据的insert语句)

转载自：http://hi.baidu.com/pigarmy/blog/item/109894c445eab0a28326ac5a.html

最近需要导出一个表的数据并生成insert语句，发现SQL Server的自带工具并米有此功能。BAIDU一下得到如下方法（亲测OK）

用这个存储过程可以实现：

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

然后将运行后的结果存成.sql，再用SQL Server Management Studio打开执行就Ok了！
