SQLite学习笔记（1）-安装及其点命令

SQLite安装(版本：3.8.11.1)

在Windows上安装SQLite以及SQLite的点命令

访问点击进行下载，从Windows区进行下载

下载 sqlite-shell-win32-*.zip 和 sqlite-dll-win32-*.zip 压缩文件

从D盘下创建文件夹D:\SQLite，并将下载的二个压缩文件解压在此，将得到sqlite3.def、sqlite3.dll
和 sqlite3.exe 文件。

将D:\SQLite加入到path环境变量，最后在命令提示符下，使用 sqlite3 命令，将显示如下结果。

C:\Users\Administrator>sqlite3
