Hello everyone,
I am trying to retrieve some records from the database using date and time
comparison. The table has three columns, Row Id, Start Time and end Time.
I need to get the row id for a time which falls within the start and end
time.
I am using this query.
select RowID,
strftime('%Y-%m-%dT%H:%M:%S',starttime),
strftime('%Y-%m-%dT%H:%M',endtime) from History where
strftime('%Y-%m-%dT%H:%M',starttime) <
strftime('%Y-%m-%dT%H:%M','2006-11-17T12:17') and
strftime('%Y-%m-%dT%H:%M',endtime) >
strftime('%Y-%m-%dT%H:%M','2006-11-17T12:17');
This works well if there is only one matching row.
However if more than one row matches, I need to get the row whose start time
is closest to the given time. Say the start times are 12:10 and 12:20 and
the given time is 12:25, it should return the second record only.
I am trying the following query
strftime('%Y-%m-%dT%H:%M',endtime - starttime)
however this fails giving some negative numbers.
If anyone knows of a solution, kindly post a reply for this. Thanks in
advance.
With Regards
