无法创建Android SQLite数据库：PRAGMA错误

E/AndroidRuntime( 8614): Uncaught handler: thread main exiTing due to uncaught exception

我目前的代码：

import android.content.Context;
import android.database.cursor;
import android.database.sqlite.sqliteDatabase;
import android.database.sqlite.sqliteOpenHelper;

public class Database extends sqliteOpenHelper {

   private static String Databasename = "Entries.db"; 

   public Database(Context context) {
      super(context,Databasename,null,1);
   }

   public void onCreate(sqliteDatabase D) {
      D.execsql(
            "create table Containers ("
            + "ID INTEGER PRIMARY KEY AUTOINCREMENT,"
            + "Parent IntegeR,"
            + "Sequence IntegeR,"
            + "@R_390_4687@T"
            + ")"
      );
      D.execsql(
            "create table Files ("
            + "ID INTEGER PRIMARY KEY AUTOINCREMENT,"
            + "@R_390_4687@T,"
            + "@R_321_3801@"
            + ")"
      );
      D.execsql("INSERT INTO Containers (Parent,Sequence,Name) VALUES (0,2,\"TestLine2\")");
      D.execsql("INSERT INTO Containers (Parent,1,\"TestLine1\")");
      D.execsql("INSERT INTO Containers (Parent,3,\"TestLine3\")");
      D.execsql("INSERT INTO Containers (Parent,Name) VALUES (2,\"TestLine2-1\")");
      D.execsql("INSERT INTO Containers (Parent,\"TestLine2-2\")");
      D.close();
   }

   @Override
   public void onUpgrade(sqliteDatabase arg0,int arg1,int arg2) {
   }

   public static cursor Query(Context context,String sql) {
      StartQuerySeries(context);
      cursor Result = Query(sql);
      StopQuerySeries();
      return Result;
   }

   private static Database D = null;
   public static void StartQuerySeries(Context context) {
      D = new Database(context);
   }
   public static cursor Query(String sql) {
      sqliteDatabase X = D.getWritableDatabase();
      return X.rawQuery(sql,null);
   }
   public static void StopQuerySeries() {
      D.close();
      D = null;
   }

}

当在主Activity中调用它时,会发生错误：

Database.Query(this,"INSERT INTO Files (Parent,Name,Text) VALUES (1,\"Item1\",\"Item1 Text\")");

错误发生在“D.getWritableDatabase()”行…我最接近的事情是,在http://www.sqlite.org/c3ref/c_abort.html,故障21说“库使用不正确” – 任何帮助？

哦,我检查了 – 数据库文件确实已经创建了,但是里面没有表格,因此上面的onCreate()没有被调用.
