在哪里可以findSQLite数据库文件或转储的例子？

我真的需要一个SQLite数据库文件进行研究。 我正在C＃中创build一个应用程序，我需要一个包含许多表，字段，视图，索引，约束等的数据库。 我不想使用sqlite命令行工具自己创build它。

所以我想可能有人可以说我在哪里可以find这样的文件，可能是不同的应用程序或例子，甚至可以发送给我自己的数据库文件。 我将不胜感激任何帮助。

Answer 1

有一个很好的示例数据库叫做Chinook。 它试图成为取代NorthWind的现代化例子。 他们有不同的数据库服务器版本，包括SQLite。

• 主页，DB图等。http ://chinookdatabase.codeplex.com/
• Github（似乎比CodePlex更新） https://github.com/lerocha/chinook-database
• 最新的SQLite下载到date的文章： https : //chinookdatabase.codeplex.com/releases/view/55681#fileDownload6
• 下载SQLite示例数据库直接获取Chinook数据库文件http://www.sqlitetutorial.net/sqlite-sample-database/
• CodePlex上更多与SQLite相关的项目和示例http://www.codeplex.com/site/search?query=sqlite&ac=8

另外，请在SQLite .NET客户端论坛中查看这个示例（附在第一篇文章）

• 使Microsoft EFQuerySamples项目与SQLite一起工作

也许一个GUI工具来创build数据库的东西将使启动更容易，检查这一个，免费供个人使用

• http://www.sqliteexpert.com/

就我个人而言，我创build了SQLite数据库来testingNHibernate映射。 通常我创build我的类和映射，然后使用映射生成模式到一个新的SQLite文件（或更频繁地在内存数据库中）并使用它。 大多数NHibernate的介绍文章也是这样做的。

尝试searchsqlite教程 – 他们经常有你可以下载的例子（例如http://souptonuts.sourceforge.net/readme_sqlite_tutorial.html ）

我使用了sqlightCrud操作

第一个创build数据库类。 package com.db;

import android.content.ContentValues; import android.content.Context; import android.database.Cursor; import android.database.SQLException; import android.database.sqlite.SQLiteDatabase; import android.database.sqlite.SQLiteOpenHelper; import android.util.Log; import android.widget.Toast; public class DataBaseSampleActivity { /** for database */ static final String DataBaseName = "EmployeDB"; /** for employee table */ static final String EmployeTable = "Employees";

private final Context context; private DatabaseHelper DBHelper; private SQLiteDatabase db; public DataBaseSampleActivity(Context ctx){ Log.i("test****", "**test***"); this.context = ctx; DBHelper = new DatabaseHelper(context); } private static class DatabaseHelper extends SQLiteOpenHelper{ public DatabaseHelper(Context context){ super(context, DataBaseName , null, DATABASE_VERSION); Log.i("context","context"); } @Override public void onCreate(SQLiteDatabase db) { // TODO Auto-generated method stub db.execSQL(EMPLOYEE_TABLE_CREATE);

db.execSQL("DROP TABLE IF EXISTS " + EmployeTable); onCreate(db); } }; public DataBaseSampleActivity open() throws SQLException{ db = DBHelper.getWritableDatabase(); Log.i("open", "message"); return this; } public void close(){ DBHelper.close(); } //public long insert(Integer empid, String empname, Integer empage, String empdept) { public long insert(String empname, Integer empage, String empdept) { Log.i("**** suruchitest **** ","*** test ***"); ContentValues initialValues = new ContentValues(); //initialValues.put(ColEmpID, empid); initialValues.put(ColEmpName, empname); initialValues.put(ColEmpAge, empage); initialValues.put(ColDept, empdept); return db.insert(EmployeTable, null, initialValues); } public Cursor getEmpValues(){ Cursor mCursor = db.query(EmployeTable, null, null, null, null, null, null); return mCursor; } public boolean deleteEmpList(long rowId){ Toast.makeText(context, "deleted", 2000).show();

return false; } } } 2. create Main Activity package com.db; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.util.Log; import android.view.View; import android.view.View.OnClickListener;

buttonsubmit.setOnClickListener(this); // empid =(EditText) findViewById(R.id.empid); empname =(EditText) findViewById(R.id.empname); empage =(EditText) findViewById(R.id.empage); empdept =(EditText) findViewById(R.id.empdpt); } @Override public void onClick(View v) { // TODO Auto-generated method stub DataBaseSampleActivity dbObj = new DataBaseSampleActivity(getApplicationContext()); // String Emp_ids = empid.getText().toString();

//Toast.makeText(getApplicationContext(), "temp"+temp, 3000).show(); dbObj.close(); Intent intent = new Intent(this,ShowListView.class); startActivity(intent); } catch (Exception e) { // TODO: handle exception Log.i("catch", "message");
