Question

More specifically, the first two columns of my read-only database are the row number (the _id integer primary key), and a date and time in the text format 7/21/2011 HH:MM:SS PM. In my Android app, the user selects a start and end time (HH:MM), and then data about that time interval is displayed graphically. How do I search this second row of my database for the inputted times?

Answer 1

So if your Date Column contains TEXT(since there is no DATE in SQLite), you should use the SQLite function

    strftime(format, timestring, modifier, modifier, ...)

See docs SQLite Date functions

So you SQL query may look something like this:

    SELECT * FROM mytable WHERE strftime('MM-DD-YYYY HH:MM:SS', date_column) < strftime('MM-DD-YYYY HH:MM:SS', '7/21/2010 22:00:00')

where the last date parameter will be the inputted date.
