我們這里下載的是命令行版本，所以是一個可執(zhí)行文件，還有一個動態(tài)鏈接庫版本，如果你的應用程序需要嵌入式數(shù)據(jù)庫，可以下載這個版本。當然，如果你愿意折騰，下載源代碼自己編譯也是可以的。下載完成，解壓出來就一個文件： sqlite3.exe ，可以放置到任意一個路徑下，然后把這個路徑加入到 PATH 環(huán)境變量中，這樣我們就可以隨時在控制臺中運行 SQLite 命令行工具了。
創(chuàng)建一個新數(shù)據(jù)庫和打開一個已經(jīng)存在的數(shù)據(jù)庫命令是一模一樣的，如果文件在當前目錄下不存在，則新建；如果存在，則打開。

有好幾種顯示模式，默認的是 list 顯示模式，一般我們使用 column 顯示模式，還有其他幾種顯示模式可以 .help 看 mode 相關內(nèi)容。看看下面的圖，和上面是不是顯示的不一樣了？
如果我們每次進入命令行都要重新設置顯示格式，很麻煩，其實 .show 命令列出的所有設置項都可以保存到一個 .sqliterc 文件中，這樣每次進入命令行就自動設置好了。.sqlterc 文件在 Linux 下保存在用戶的 Home 目錄下，在 Windows 下可以保存到任何目錄下，但是需要設置環(huán)境變量讓數(shù)據(jù)庫引擎能找到它，感興趣的可以看看幫助。
