(3)写一个简单的界面 (4)在后端代码中先写上这些代码 //获取数据库路径publicstaticstringSQLitePath = AppDomain.CurrentDomain.BaseDirectory +"db/SQLiteDemo1.db";//数据库连接字符串publicstaticstringstr =string.Format("Data Source={0};Pooling
由sqlite3_open完成的数据库初始加载其实是一个很受限的攻击面,它基本上只是为了打开数据库进行大量程序设置和参数配置。所以我们的主要攻击面是经过AFL模糊测试的头部解析部分(https://www.sqlite.org/fileformat.html#the_database_header)。 当我们开始对数据库进行查询时,就有点意思了。 引用SQLite作者的话: “...
SQLiteHelper _SQLiteHelper = new SQLiteHelper("Data Source=MyDatabase.sqlite;Version=3;DateTimeFormat=Ticks;"); //在MyDatabase数据库 执行-创建表格 _SQLiteHelper.ExecuteNonQuery(CommandType.Text, "CREATE TABLE IF NOT EXISTS highscores (name varchar(20), score int)"); ///DataSet obj2 = _SQLi...

sqlitereader 多线程 简介 SQL*Loader(SQLLDR)是Oracle的高速批量数据加载工具。这是一个非常有用的工具,可用于多种平面文件格式向Oralce数据库中加载数据。SQLLDR可以在极短的时间内加载数量庞大的数据。它有两种操作模式。 传统路径:(conventional path):SQLLDR会利用SQL插入为我们加载数据。
SQLiteDataReader dr = cmd.ExecuteReader(); StringBuilder sb = new StringBuilder(); while (dr.Read()) { sb.Append(dr.GetInt32(0)).Append(""n").Append(dr.GetString(1)); } Console.WriteLine(sb); 只要用过ADO.NET的看懂上面的代码都没问题吧,行,我们运行一下吧!

There is an additional quasi-persistent "-wal" file and "-shm" shared memory file associated with each database, which can make SQLite less appealing for use as an application file-format. There is the extra operation of checkpointing which, though automatic by default, is still something tha...
