I can't seem to get reliable results from the query against a sqlite database using a datetime string as a comparison as so:

select * 
  from table_1 
 where mydate >= '1/1/2009' and mydate <= '5/5/2009'

how should I handle datetime comparisons to sqlite?

update: field mydate is a DateTime datatype

To solve this problem, I store dates as YYYYMMDD. Thus, where mydate >= '20090101' and mydate <= '20050505'

It just plain WORKS all the time. You may only need to write a parser to handle how users might enter their dates so you can convert them to YYYYMMDD.
