無法在sqlite的

Question

繼創建表是我的查詢創建表，

String CREATE_OWNER_TABLE = "CREATE TABLE " + TABLE_OWNER + "(" + KEY_NAME + " TEXT NOT NULL," + KEY_CODE + " TEXT NOT NULL," + KEY_NUMBER + " TEXT NOT NULL," + KEY_SUM + "TEXT NOT NULL );";

Answer 1

你缺少你最後一列的數據類型聲明

KEY_SUM + "TEXT NOT NULL 

前的空間添加一個空格像下面列的錯誤，

String CREATE_OWNER_TABLE = "CREATE TABLE " + TABLE_OWNER + "(" + KEY_NAME + " TEXT NOT NULL," + KEY_CODE + " TEXT NOT NULL," + KEY_NUMBER + " TEXT NOT NULL," + KEY_SUM + " TEXT NOT NULL );"; 
db.execSQL(CREATE_OWNER_TABLE);

試試這個

String CREATE_OWNER_TABLE = "CREATE TABLE " + TABLE_OWNER + "(" + KEY_NAME + " TEXT NOT NULL," + KEY_CODE + " TEXT NOT NULL," + KEY_NUMBER + " TEXT NOT NULL," + KEY_SUM + " TEXT NOT NULL);";
