Answer 1

Вы пропускаете запятую, которая вызывает ошибку синтаксиса. Вот скорректированный код:

String query2 = " CREATE TABLE " + TABLE_PLAT + "(" + 
     COLUMN_IDPLAT + " INTEGER PRIMARY KEY, " + 
     COLUMN_PLATNAME + " TEXT, " + 
     COLUMN_PRIXPLAT + " INTEGER, " + 
     COLUMN_REFCATEGORIE + " INTEGER NOT NULL, " +" FOREIGN KEY ("+COLUMN_REFCATEGORIE+") REFERENCES " +TABLE_CATEGORIE+" ("+COLUMN_IDCATEGORIE ")," + 
     // The missing comma was here:...............................................................................................................^ 
     COLUMN_REFINGREDIENT + " INTEGER NOT NULL, " +" FOREIGN KEY("+COLUMN_REFINGREDIENT+ ") REFERENCES " +TABLE_INGREDIENT+" ("+COLUMN_IDINGREDIENT+"));"; 
db.execSQL(query2);
