perl脚本备份还原sqlserver-ocpyang
写了一个perl脚本灵活来备份或还原。1.将config.txt保存到c盘根目录
username:sa
password:passwd123!
根据实际情况修改该文件内容
2.执行bcp.pl
#!C:\Perl64\bin
#通过BCP备份和还原SQLSERVER指定的表
use 5.014;
#加载用户和密码配置文件
my $username ;
my $passwd;
##获取用户名
my $dir="c:";
$dir=$dir."/";
my $filename="config.txt";
my $keysword="username:";
my $count="50";
my $begincount=index($keysword,":");
my($file);
open(FILEH,$dir.$filename);
while(my $test=){
if((index($test,$keysword))>=0){
my $test1=substr($test,$begincount+1,$count);
#print "$test1";
chomp($username=$test1);
}
}
close(FILEH);
##获取密码
my $dir="c:";
$dir=$dir."/";
my $filename="config.txt";
my $keysword="password:";
my $count="50";
my $begincount=index($keysword,":");
my($file);
open(FILEH,$dir.$filename);
while(my $test=){
if((index($test,$keysword))>=0){
my $test2=substr($test,$begincount+1,$count);
#print "$test2";
chomp($passwd=$test2);
}
}
close(FILEH);
