android.database.sqlite.SQLiteException：沒有這樣的列：AA：，在編譯：從猛男所在地址= AA

我試圖以檢索來自Android的SQLite數據庫的數據，但它的givine例外選取名稱，沒有這樣的列： android.database.sqlite.SQLiteException：沒有這樣的列：AA：，在編譯：從猛男所在地址= AA

sqlite的選擇查詢是 - ：

c=db.rawQuery("Select Name from stud Where Address="+a,null);

例外： -

這只是因爲你的sql查詢是錯誤的。查詢文本時，需要在查詢字符串周圍添加單引號。

你行應爲：

c=db.rawQuery("Select Name from stud Where Address='"+a+"'",null);

問題是在地址！這是SQL中的內置函數，它不能是列名！ –

對不起，我認爲你錯了。地址從來沒有，也不會在任何SQL實現中成爲保留字。使用SQL最基本的用例是存儲人員及其地址。將ADDRESS作爲保留字是非常愚蠢的。 – Yahel

我剛剛測試過這個，當我在SQL查詢中輸入地址時，它是藍色的，那麼爲什麼它是藍色的，如果它不是保留字？！ –

如果您正在使用string那麼你必須表達它在單引號，如：

Cursor cursor = db.rawQuery("SELECT '"+WINNER+"' FROM '"+TABLE.trim()+"' WHERE 
     country1='"+c1.trim()+"' AND Country2='"+c2.trim()+"'", null);

如果您是代表一個int值那麼你就可以簡單地使用像這樣：+num+
