こんにちは、ユーザー ID に従って 2 つの日付の間でレコードを取得したいと考えています。

レコードを取得するための私のクエリ:

System.out.println("in data function");
Cursor curCalllog = db.rawQuery("SELECT KEY_ID FROM "+ KK_AIRLINEBOOK + 
" WHERE " + KEY_Bookingdate +  " BETWEEN ?  AND ?", new String[]{startdate, enddate});

次のエラーが表示されるため、クエリを手伝ってください-:no such column id クエリの何が問題なのですか。私を助けてください。

変化する

Cursor curCalllog = db.rawQuery("SELECT KEY_ID FROM "+ KK_AIRLINEBOOK + 
" WHERE " + KEY_Bookingdate +  " BETWEEN ?  AND ?", new String[]{startdate, enddate});

に

Cursor curCalllog = db.rawQuery("SELECT "+KEY_ID+" FROM "+ KK_AIRLINEBOOK + 
" WHERE " + KEY_Bookingdate +  " BETWEEN ?  AND ?", new String[]{startdate, enddate});

問題が発生した理由を理解していただければ幸いです。KEY_ID 列を探していました。KEY_ID に含まれる値ではありません。

logcat を参照してください。

Caused by: android.database.sqlite.SQLiteException: no such column: KEY_ID (code 1): , while compiling: SELECT KEY_ID FROM Airline WHERE bookingdate BETWEEN ?  AND ?
