如何在sqlite中刪除數據庫？

Question

我在android中使用SQLite。我想刪除數據庫。

例如：mysql- drop database dbname

如何實現SQLite的代碼？

Answer 1

創建或刪除數據庫的概念對於像SQLite這樣的嵌入式數據庫引擎沒有意義。它只與客戶端服務器數據庫系統有關，比如MySQL或Postgres使用的數據庫系統。

要創建新數據庫，只需執行sqlite_open()或從命令行sqlite3 databasefilename。

要刪除數據庫，請刪除該文件。

參考：sqlite - Unsupported SQL

Answer 2

從http://www.sqlite.org/cvstrac/wiki?p=UnsupportedSql

要創建一個新的數據庫，只是做 sqlite_open（）。刪除數據庫， 刪除該文件。

Answer 3

可以通過發出SQL命令，你通常會下降tables。如果你想刪除整個數據庫，你必須刪除文件。您可以刪除所在的文件下

data/data/com.your.app.name/database/[databasefilename]

你可以從所謂的「FileBrowser」出例如「Android」的範疇的Eclipse視圖做到這一點。或直接在您的模擬器或手機上。

Answer 4

刪除您的應用程序的數據庫試試這個：

this.deleteDatabase("databasename.db"); 

這將刪除數據庫文件

Answer 5

如果你想刪除的數據庫編程，你可以使用deleteDatabase從Context類：

deleteDatabase（String name）
Delete an existencein g與此Context的應用程序包關聯的私有SQLiteDatabase。

Answer 6

試試這個：

context.deleteDatabase(DATABASE_NAME);

SQLite database FAQ: How do I drop a SQLite database? 

People used to working with other databases are used to having a "drop database" command, but in SQLite there is no similar command. The reason? In SQLite there is no "database server" -- SQLite is an embedded database, and your database is entirely contained in one file. So there is no need for a SQLite drop database command. 

To "drop" a SQLite database, all you have to do is delete the SQLite database file you were accessing.

如果使用SQLiteOpenHelper你可以做到這一點

 String myPath = DB_PATH + DB_NAME; 
     SQLiteDatabase.deleteDatabase(new File(myPath));
