SQLite中的錯誤

我創建了一個SQLite，我在表中添加了4列，但是當添加第五列「productadd」時無法找到。這裏有什麼問題？對不起，我真的很新的SQLiteSQLite中的錯誤

下面是我DatabaseHelper類

db.execSQL("CREATE TABLE if not exists producttable(id INTEGER PRIMARY KEY AUTOINCREMENT," 
       + " productidno" 
       + " TEXT ," 
       + " productname" 
       + " TEXT," 
       + " productprice" 
       + " TEXT," 
       + " productdest" 
       + " TEXT," 
       + " productadd" 
       +" TEXT);");

我的logcat：

07-28 15:38:49.460: I/Database(382): sqlite returned: error code = 1, msg = table producttable has no column named productadd 
07-28 15:38:49.492: E/Database(382): Error inserting productadd=hope productidno=this productdest=and productprice=me productname=is

productprice與TEXT之間沒有空格 –

db.execSQL("CREATE TABLE if not exists producttable(id INTEGER PRIMARY KEY AUTOINCREMENT," 
       + " productidno" 
       + " TEXT ," 
       + " productname" 
       + " TEXT," 
       + " productprice" 
       + " TEXT," 
       + " productdest" 
       +" TEXT)");

存在丟失的空間在這裏：

+ "productprice" 
    + "TEXT,"

變化到：

+ "productprice " 
       + "TEXT,"
