SQLite管理工具SQLite-tools

這裡目前不會提到如何在程式中加入SQLite來處理程式要管理的資料,主要是介紹透過SQLite的管理工具,來管理在SQLite檔案中的資料。

SQLite的Slogan : Small. Fast. Reliable. Choose any three.
SQLite官網:https://www.sqlite.org/
SQLite Download Page : https://www.sqlite.org/download.html 
在SQLite的下載頁面,以搜尋的方式找到所需作業系統的對應版本:
以下載 sqlite-tools-win32-x86-3290000.zip 為例


透過7-zip提供的CRC SHA 檔案驗證功能,計算所下載檔案的SHA1值:
(只要能計算SHA1都可以,不一定要用7-zip;但驗證是必要的,尤其是在非官方網站或知名度、信賴度較低)


SHA-1比對吻合,就可以安心的使用了...

SQLite-tools不需要安裝,解壓縮即可使用 ... SQLite提供文字界面的操作方式,開啟sqlite3.exe後,可以使用 .help 查看相關管指令
