一、创建/删除表
String sql="Create table "+TABLE_NAME+"("+FIELD_ID+" integer primary key autoincrement," +FIELD_TITLE+" text );";
db.execSQL(sql);
String sql=" DROP TABLE IF EXISTS "+TABLE_NAME;
db.execSQL(sql);
二、查询
从表中查询数据(in) SELECT * FROM meta where media_id in (1,2,9);
三、插入
SQLiteDatabase db=this.getWritableDatabase();
ContentValues cv=new ContentValues();
cv.put(FIELD_TITLE, Title);
long row=db.insert(TABLE_NAME, null, cv);
四、更新
SQLiteDatabase db=this.getWritableDatabase();
String where=FIELD_ID+"=?";
String[] whereValue={Integer.toString(id)};
ContentValues cv=new ContentValues();
cv.put(FIELD_TITLE, Title);
db.update(TABLE_NAME, cv, where, whereValue);
五、删除
SQLiteDatabase db=this.getWritableDatabase();
String where=FIELD_ID+"=?";
String[] whereValue={Integer.toString(id)};
db.delete(TABLE_NAME, where, whereValue);
