1 修改SQL2005 SA帐号密码的方法

工作中遇到SA帐号密码忘记的问题,后来一个同事说了一个解决办法:

只要执行以下的SQL语句即可:exec sp_password null,'sa123','sa' 

 (意思是把sa的帐号密码修改为sa123)。

2 远程桌面登录弹出连接数达到最大,此时会一直登录不上,可以运行这个命令 mstsc /console。具体操作:

打开  运行 输入 mstsc /console 命令,按回车,打开远程登录界面。此时去登录不爱最大数的限制了。

 

3 ORACLE  Decode 使用示例:

         select  Decode(5, 1, '定制操作', 2, '退定操作', '未知类型') AS 操作类型 from dual

 详细用法参照 http://www.cnblogs.com/chhuic/archive/2011/07/20/2111323.html 

 01.拷贝程序文件.bat
CLS
MD Bin
MD Bin\Common
MD Bin\Bin2005
MD Bin\Bin2008

XCOPY ..\..\..\BIN\RM\Common Bin\Common /E /R /Y
XCOPY ..\..\..\BIN\RM\Bin2005 Bin\Bin2005 /E /R /Y
XCOPY ..\..\..\BIN\RM\Bin2008 Bin\Bin2008 /E /R /Y

RD Bin\DBUpdate /S /Q
DEL Bin\CHS\R810RMCC.mdb
DEL Bin\CHS\RMCC_Access.ini
DEL Bin\ENU\R810RMCC.mdb
DEL Bin\ENU\RMCC_Access.ini

02.删除安装多余文件.bat
CLS
RD bin /S /Q
RD Media /S /Q

03.编译版本.bat
"D:\Program Files\Macrovision\IS11.5\System\IsCmdBld.exe" -p "ViewPoint RM R860.ism"
