數據庫處理程序，添加項目問題

Question

我遇到插入查詢問題。當我嘗試插入數據庫時​​，它在日誌貓中說active:列不存在。請你指出我在哪裏犯錯。

其實我得到這個異常：

SQLiteException: table video has no column named active: , while compiling: insert into video (fav, path, subcat_id , video_name, active) VALUES ('0','/mnt/sdcard/Samsung','videocat','Samsung','1') 

這是我SQLITEHELPER類的代碼

public class DatabaseHelper extends SQLiteOpenHelper { 

    //changing master 
    // Logcat tag 
    //add comment 
    private static final String LOG = "DatabaseHelper"; 

    // Database Version 
    private static final int DATABASE_VERSION = 9; 

    // Database Name 

    private static final String DATABASE_NAME = "contactsManager"; 

    // Table Names 

    private static final String TABLE_VIDEO = "video"; 
    private static final String TABLE_PICTURE = "picture"; 
    private static final String TABLE_MUSIC = "music"; 

    // Common column names 

    private static final String KEY_ID = "id"; 
    private static final String KEY_FAV = "fav"; 
    private static final String KEY_ACTIVE = "active"; 

    // MUSIC Table - column names 

    private static final String KEY_MUSIC_PATH = "path"; 
    private static final String KEY_MUSIC_ALBUM = "is_album"; 
    private static final String KEY_MUSIC_NAME = "music_name"; 



    // PICTURE Table - column names 

    private static final String KEY_PICTURE_PATH = "path"; 
    private static final String KEY_PICTURE_ALBUM = "is_album"; 
    private static final String KEY_PICTURE_NAME = "picture_name"; 

    // VIDEO Table - column names 

    private static final String KEY_VIDEO_PATH = "path"; 
    private static final String KEY_VIDEO_SUBCAT_ID = "subcat_id"; 
    private static final String KEY_VIDEO_NAME = "video_name"; 


    // Table Create Statements

    public DatabaseHelper(Context context) { 
     super(context, DATABASE_NAME, null, DATABASE_VERSION); 
    } 



    @Override 
    public void onCreate(SQLiteDatabase db) { 
     // TODO Auto-generated method stub 
     // creating required tables 

     db.execSQL(CREATE_TABLE_PICTURE); 
     db.execSQL(CREATE_TABLE_MUSIC); 
     db.execSQL(CREATE_TABLE_VIDEO); 

    } 

    @Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     // TODO Auto-generated method stub 
     // on upgrade drop older tables 

     db.execSQL("DROP TABLE IF EXISTS " + TABLE_VIDEO); 
     db.execSQL("DROP TABLE IF EXISTS " + TABLE_PICTURE); 
     db.execSQL("DROP TABLE IF EXISTS " + TABLE_MUSIC); 

     // create new tables 
     onCreate(db); 
    } 




    // add videos 
    public void addvideos(Video item, int active, String subcat) { 
     SQLiteDatabase db = this.getWritableDatabase(); 


     db.execSQL("insert into video (fav, path, subcat_id , video_name, active) VALUES (" + "'" + item.getFavourite() + "',"+ "'" + item.getPath() + "'," + "'" + subcat + "'," + "'" + item.getName() +"'," + "'" + active + "'" + ")"); 

    } 

    // add pictures 
    public void addpictures(Picture item, int is_album, int active) { 
     SQLiteDatabase db = this.getWritableDatabase(); 


     db.execSQL("insert into picture (fav, path, is_album , picture_name, active) VALUES (" + "'" + item.getFavourite() + "',"+ "'" + item.getPath() + "'," + "'" + is_album + "'," + "'" + item.getName() +"'," + "'" + active + "'" + ")"); 

    } 

    // add music 
    public void addmusic(Music item, int catid, int active) {

Answer 1

這裏：

+ KEY_ACTIVE + "INTEGER)"; 

您必須在「INTEGER」之前插入一個空格「」;

所以：

+ KEY_ACTIVE + " INTEGER)"; 

你有這樣的問題，在你的代碼的3倍。

Answer 2

您錯過了列名和數據類型之間的空間。事實上，在你的所有CREATE_TABLE語句中，你都是一樣的。您需要用「INTEGER」替換「INTEGER」）「

private static final String CREATE_TABLE_VIDEO = "CREATE TABLE " 
     + TABLE_VIDEO + "(" + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," 
     + KEY_FAV + " INTEGER," 
     + KEY_VIDEO_PATH + " TEXT," 
     + KEY_VIDEO_SUBCAT_ID + " TEXT," 
     + KEY_VIDEO_NAME + " TEXT" 
     + KEY_ACTIVE + " INTEGER)"; // SPACE INSERTED BEFORE INTEGER 

希望這有助於！
