   在目前的工作中需要解决复制整个SqlServer数据库的问题,复制的内容包括数据库大纲、数据库中的存储过程、函数、表结构、主外键关系以及表中的所有数据等,也就是说copy版本与原数据库一模一样。经过一段时间的摸索,找到的一个比较简单的解决方案是:
(1)在复制数据库之前,先备份该数据库到文件。
(2)依据备份文件创建新的数据库,并Restore即可。

   备份数据库可用如下Sql语句:

string.Format("backup database {0} to disk = '{1}';", dbName, bakFilePath)

   依据备份文件创建并Restore新数据库可以使用如下存储过程实现:

CREATE PROCEDURE CopyDB
(
@newDbName varchar(50),  --新数据库名称
@dbDataDirPath varchar(100), --数据库安装的Data文件夹目录路径
@soureDbName varchar(100), --源数据库名称
@soureBackupFilePATH varchar(100)--源数据库备份文件的路径
)
AS
declare @sql varchar(3000)
set @sql='
create database 
'+@newDbName+'
ON
(
  name=
'+@soureDbName+'_Data,
  filename=
'''+@dbDataDirPath+@newDbName+'_Data.mdf'',
   SIZE = 10,
   FILEGROWTH = 15% 
)
LOG ON
(
  name=
'''+@soureDbName+'_Log'',
  filename=
'''+@dbDataDirPath+@newDbName+'_Log.LDF'',
   SIZE = 5MB,
   MAXSIZE = 25MB,
   FILEGROWTH = 5MB
)
--开始还原
RESTORE DATABASE 
'+@newDbName+' from disk='''+@soureBackupFilePATH+''' WITH REPLACE
'
exec(@sql)
GO


   测试的代码如下:

                IListSPParameter> paraList = new ListSPParameter>();
                SPParameter para1 
= new SPParameter("newDbName", ParameterDirection.Input, "EASNew9");
                paraList.Add(para1);
                SPParameter para2 
= new SPParameter("dbDataDirPath", ParameterDirection.Input, @"C:\Program Files\Microsoft SQL Server\MSSQL\Data\");
                paraList.Add(para2); 
                SPParameter para3 
= new SPParameter("soureDbName", ParameterDirection.Input, "AutoSchedulerSystem");
                paraList.Add(para3);
                SPParameter para4 
= new SPParameter("soureBackupFilePATH", ParameterDirection.Input, @"d:\sqlDatabase\AutoSchedulerSystem");
                paraList.Add(para4);
                IDictionary
stringobject> outParas = null;
                Program.DataAccesser.GetSPAccesser(
null).ExcuteNoneQuery("CopyDB", paraList, out outParas);

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
