Sqliteをエラー私はsqliteのエラーを取得していますなぜテーブル

Question

を作成しながら、任意のヘルプは

public static final String KEY_ORDERID="id_order"; 
    public static final String KEY_SUBTRUCKID="id_subtruck"; 
    public static final String KEY_TRUCK_NUMBER="id_trucknmbr"; 

private static final String CREATE_MASTER_TRUCK_DETAIL = "CREATE TABLE " 
      + TABLE_TRUCK_DETAIL_MASTER_DATA + " (" 
      + KEY_SUBTRUCKID + " TEXT," 
      + KEY_ORDERID + " INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL"+")"; 

    private static final String CREATE_SLAVE_TRUCK_DETAIL = "CREATE TABLE " 
     + TABLE_TRUCK_DETAIL_SLAVE_DATA+ " (" 
     + KEY_ORDERID + " INTEGER," 
     + KEY_TRUCK_NUMBER + " TEXT," 
     + " FOREIGN KEY ("+KEY_SUBTRUCKID+") REFERENCES " 
     +TABLE_TRUCK_DETAIL_MASTER_DATA+" ("+KEY_SUBTRUCKID+"))"; 

ログインエラー感謝：CREATE_SLAVE_TRUCK_DETAILでTABLE_TRUCK_DETAIL_MASTER_DATAに

unknown column "id_subtruck" in foreign key definition (code 1): , while compiling: CREATE TABLE truckslave (id_order INTEGER,id_trucknmbr TEXT, FOREIGN KEY (id_subtruck) REFERENCES truckmaster (id_subtruck)) 

Answer 1

変更CREATE_MASTER_TRUCK_DETAILを：

private static final String CREATE_SLAVE_TRUCK_DETAIL = "CREATE TABLE " 
    + TABLE_TRUCK_DETAIL_SLAVE_DATA+ " (" 
    + KEY_ORDERID + " INTEGER," 
    + KEY_TRUCK_NUMBER + " TEXT," 
    + KEY_SUBTRUCKID_SLAVE + " TEXT,"//Define new column which would be the foreign key 
    + " FOREIGN KEY ("+KEY_SUBTRUCKID_SLAVE+") REFERENCES " 
    + TABLE_TRUCK_DETAIL_MASTER_DATA +" ("+KEY_SUBTRUCKID+"))"; 

私は間違ってあなたが追加したと思いますマスタテーブル名の代わりに、マスタテーブルの文を作成します。

@ GVillani82で指摘されているように、TABLE_TRUCK_DETAIL_SLAVE_DATAにKEY_SUBTRUCKID列を参照する列を定義する必要があります。TABLE_TRUCK_DETAIL_MASTER_DATAです。
