Question

How do I “translate” the following SQL statement for using sqliteDatabase.delete(...) –

DELETE FROM EVENTS_TB WHERE event_time < some_time

Where event_time and some_time are long and some_time is calculated time according to user’s selection.

Answer 1

You should use delete() method of SQLiteDatabase instance.

sq.delete("<tablename>", "event_time < ?", new String {String.valueOf(some_time)});

or cleaner is when you declared db columns like static final fields for example

static final String KEY_EVENT_TIME = "event_time";
static final String TABLE_NAME = "EVENTS_TB";

sq.delete(TABLE_NAME , KEY_EVENT_TIME + " < ?", new String {String.valueOf(some_time)});
