Python + SQLite query to find entries that sit in a specified time slot

Question

Hi, I want to store a row in an SQLite 3 table for each booking in my diary.

Each row will have a 'start time' and a 'end time'.

Does any one know how I can query the table for an event at a given time?

E.g. Return any rows that happen at say 10:30am

Thanks

SQLite3 doesn't have a datetime type, though it does have date and time functions.

Typically you store dates and times in your database in something like ISO 8601 format: YYYY-MM-DD HH:MM:SS. Then datetimes sort lexicographically into time order.

With your datetimes stored this way, you simply use text comparisons such as

SELECT * FROM tbl WHERE tbl.start = '2009-02-01 10:30:00'

or

SELECT * FROM tbl WHERE '2009-02-01 10:30:00' BETWEEN tbl.start AND tbl.end;
