'how can I push notifications using data already built in SQLite?

I'm currently developing a notification type Android app, how can I push notifications using data already built in SQLite?

Data table fields:
[notification title]
[build date]
[Duration of days]
[time when the daily reminder starts]
[Reminder Interval]
[end date]

SQL Table:
db.execSQL("CREATE TABLE NF"+
                "(_id INTEGER PRIMARY KEY NOT NULL , "+
                "type TEXT NOT NULL,"+
                "name TEXT NOT NULL,"+
                "date DATE NOT NULL,"+
                "times INTEGER NOT NULL,"+ 
                "startTime TIMES NOT NULL,"+
                "days INTEGER NOT NULL,"+
                "endDate DATE NOT NULL)");

I want to use AlarmManager to implement this function, but I can't find the relevant application case, please help me 😭
