在android中按月从数据库获取值

I have a database where I have a table:

我想要获取 11 月至 11 月的所有值。 我创建了类似的东西：

public static List<Plan> getPlanListByMonth(SQLiteDatabase db, DateTime date) {

        String where = "strftime('%m', '"+"date"+"') = " +
                "'"+"11"+"'";

        Cursor cursor = db.query(TABLE_NAME, null, where,
                null, null, null, null, null);

        return getPlanList(cursor);
    }

    private static List<Plan> getPlanList(Cursor cursor) {

        List<Plan> PlanList = null;

        if (cursor != null) {

            PlanList = new ArrayList<>();

            if(cursor.moveToFirst()) {

                do {
                    Object obj = getPlan(cursor);
                    PlanList.add((Plan) obj);
                } while (cursor.moveToNext());
            }

            cursor.close();
        }

        return PlanList;
    }

但没有效果。知道如何按月获取所有值吗？

Oh well.

将您的查询更改为阅读

SELECT * FROM workoutPlan WHERE strftime('%m', date) = '11'

or

SELECT * FROM workoutPlan WHERE CAST((strftime('%m', date)) AS INTEGER) = 11

就这样。
