将sqlserver表中的数据导出sql语句

Cat. — Wed, 02 May 2012 15:39:11 +0000

输入表名，生成插入语句

drop proc proc_insert
go
create proc proc_insert (@tablename varchar(256))
as
begin
set nocount on
declare @sqlstr varchar(4000)
declare @sqlstr1 varchar(4000)
declare @sqlstr2 varchar(4000)
select @sqlstr='select ''insert '+@tablename
select @sqlstr1=''
select @sqlstr2=' ('
select @sqlstr1= ' values ( ''+'
select @sqlstr1=@sqlstr1+col+'+'',''+' ,@sqlstr2=@sqlstr2+name +',' from (select case
-- when a.xtype =173 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar('+convert(varchar(4),a.length*2+2)+'),'+a.name +')'+' end'
when a.xtype =127 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(20),'+a.name +')'+' end'
when a.xtype =104 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(1),'+a.name +')'+' end'
when a.xtype =175 then 'case when '+a.name+' is null then ''NULL'' else '+'''''''''+'+'replace('+a.name+','''''''','''''''''''')' + '+'''''''''+' end'
when a.xtype =61 then 'case when '+a.name+' is null then ''NULL'' else '+'''''''''+'+'convert(varchar(23),'+a.name +',121)'+ '+'''''''''+' end'
when a.xtype =106 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar('+convert(varchar(4),a.xprec+2)+'),'+a.name +')'+' end'

when a.xtype =108 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar('+convert(varchar(4),a.xprec+2)+'),'+a.name +')'+' end'
when a.xtype =231 then 'case when '+a.name+' is null then ''NULL'' else '+'''''''''+'+'replace('+a.name+','''''''','''''''''''')' + '+'''''''''+' end'
when a.xtype =59 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(23),'+a.name +',2)'+' end'
when a.xtype =58 then 'case when '+a.name+' is null then ''NULL'' else '+'''''''''+'+'convert(varchar(23),'+a.name +',121)'+ '+'''''''''+' end'
when a.xtype =52 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(12),'+a.name +')'+' end'
when a.xtype =122 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(22),'+a.name +')'+' end'
when a.xtype =48 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(6),'+a.name +')'+' end'
-- when a.xtype =165 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar('+convert(varchar(4),a.length*2+2)+'),'+a.name +')'+' end'
when a.xtype =167 then 'case when '+a.name+' is null then ''NULL'' else '+'''''''''+'+'replace('+a.name+','''''''','''''''''''')' + '+'''''''''+' end'
else '''NULL'''
end as col,a.colid,a.name
from syscolumns a where a.id = object_id(@tablename) and a.xtype <>189 and a.xtype <>34 and a.xtype <>35 and a.xtype <>36
)t order by colid

select @sqlstr=@sqlstr+left(@sqlstr2,len(@sqlstr2)-1)+') '+left(@sqlstr1,len(@sqlstr1)-3)+')'' from '+@tablename
-- print @sqlstr
exec( @sqlstr)
set nocount off
end
go

使用方法：

exec proc_insert 你的表名

选择【执行模式】为“以文本显示结果”，然后将运行后的结果存成.sql，加上用SQL Server生成的数据库脚本就可以了。

centos下添加多个IP地址的方法

Cat. — Fri, 21 Oct 2011 16:37:35 +0000

操作如下，登陆SSH:

vi /etc/syscionfig/network-scripts/ifcfg-eth0:0

第二个IP,就是

vi /etc/syscionfig/network-scripts/ifcfg-eth0:1

第三个IP,就是
ifcfg-eth0:2(由此类推)

DEVICE=eth0:0 网卡设备名称
onboot=YES 随机启动
BOOTPROTO=static 静态分配IP
IPADDR=*.*.*.* 要添加的IP地址
NETMASK=255.255.255.0 子网掩码（以实际为准）
GATEWAY=*.*.*.* 路由

如果IP是连续的，可以使用下面的方法。

vi /etc/sysconfig/network-scripts/ifcfg-eth0-range
DEVICE=eth0
BOOTPROTO=static
IPADDR_START=起始IP
IPADDR_END=结束IP
CLONENUM_START=网卡起始编号
NETMASK=子网掩码
ONBOOT=yes

保存文件然后重启网络服务立即生效

/etc/init.d/network restart

centos add IP addresses

Linux命令tar压缩排除指定目录的方法

Cat. — Thu, 11 Aug 2011 06:04:17 +0000

例如我要压缩 /cat/backup 这个文件夹 (绝对路径),但是不将里面的图片文件夹img也压缩了.可以用tar命令的--exclude 排除掉.方法

tar -zcvf backup.tar.gz --exclude=/cat/backup/img /cat/backup

排除多个目录

tar -zcvf backup.tar.gz --exclude=/cat/backup/img --exclude=/cat/backup/a --exclude=/cat/backup/b /cat/backup

iptables限制同一IP连接数

最近无聊人太多了,一直拿我的小博客来压力测试,所以不得不限制同一个IP的连接数,用iptables就可以简单设置了...

iptables -I INPUT -p tcp --dport 80 -m connlimit --connlimit-above 10 -j DROP

限制单个地址并发连接数不大于10

WordPress在Nginx中启用Apache的mod_rewrite

Cat. — Thu, 24 Feb 2011 04:48:30 +0000

其实不是真的可以另到 Nginx 支持 Apache 的 mod_rewrite 的.因为如果你的web服务器是 Nginx ,那么你的 WordPress 就会提示你的服务器环境不支持 mod_rewrite 了,但实际上是支持的,例如安装了 WP Super Cache 这插件就有这样的提示了,现在我们只要添加一行代码就可以关闭这个提示,欺骗WordPress ,让它认为是支持 mod_rewrite 方法是在主题的 functions.php 文件添加下面的代码:

add_filter('got_rewrite', 'nginx_has_rewrites');
function nginx_has_rewrites() {
return true;
}

另外,因为Nginx运行PHP是用PHP-FPM的,所以有时会导致WordPress认为php没有写权限,表现为无法自动升级,和升级插件等,下面这个代码可以修改这个错误.

add_filter('filesystem_method', 'nginx_make_filesystem_direct');
function nginx_make_filesystem_direct() {
return 'direct';
}

关闭 WordPress 3.1 的管理工具条

Cat. — Thu, 24 Feb 2011 04:33:40 +0000

升级到 WordPress 3.1 ,感觉没有什么两样,唯一无法忍受的就是它的管理工具条.所以要干掉它.方法是在后台用户资料哪里选择隐藏它就OK了.

或者在主题的functions.php文件添加一行代码:

add_filter( 'show_admin_bar', '__return_false' );

这样那个管理工具条就消失了..

利用功夫网来防止来自中国的DDOS攻击

Cat. — Mon, 08 Nov 2010 02:36:43 +0000

功夫网终于有贡献了..
不过可能会有副作用,就是连自己的网站都给功夫网封了...
下面是php代码..

if(strpos($_SERVER['REQUEST_URI'],'minghui') === false) {
header('Location:'. $_SERVER['REQUEST_URI'] . '?minghui');
exit;
}
?>
