Question

i’m facing a little complication in this logic please help me out….

so the thing is:

i have a list of times in a table like

9:00 am, 9:30 am, 10:00 am, 10:30 am, 11:00 am, 11:30 am, 12:00 pm, 12:30 pm, 1:00pm, 1:30 pm………..

please help me out with this logic……..

First, get rid of your am / pm qualifiers – use the 24 hour clock. Better yet, just use seconds or minutes since midnight.

If you’ve done that, you can then just use:

SELECT   time, ABS(time - usertime) AS diff
FROM     mytable
ORDER BY diff
LIMIT    1

That’s actually MySQL syntax, but it should be easy to port to SQLite.
