SQLite学习笔记

1、 Sqlite简介

SQLite是一款轻型的数据库,是遵守ACID的关联式数据库管理系统,它的设计目标是嵌入 式的,而且目前已经在很多嵌入式产品中使用了它,它占用资源非常的低,在嵌入式设备中,可能只需要几百K的内存就够了。它能够支持 Windows/Linux/Unix等等主流的操作系统,同时能够跟很多程序语言相结合,比如Tcl、PHP、Java、C++、.Net等,还有 ODBC接口,同样比起 Mysql、PostgreSQL这两款开源世界著名的数据库管理系统来讲,它的处理速度比他们都快。

特点:轻量级、不需要"安装"、单一文件 、跨平台/可移植性、弱类型的字段、开源

2、sqlite的数据类型

(1)一般数据采用的固定的静态数据类型,而sqlite采用的是动态的数据类型,会根据存入值自动判断,sqlite具有以下的五种常见数据类型:

  Null:空值

  Integer:带符号的整型,具体取决于存入的数值的范围大小

   Real:浮点数字,存储8个byte的浮点数

   Text:字符串文本

   Blob:二进制对象

3、利用命令的方式操作sqlite数据库

需要配置一下android的环境变量,http://www.cnblogs.com/bluestorm/archive/2012/09/27/2706420.html

(1)     打开cmd,进入到f盘,执行sqlite3 mydb.db,创建一个mydb.db文件
