Mysql: Compare is not working properly - php

Question

I have a mysql query runnning in php .
$result = mysql_query("SELECT status,initiated_by,create_timestamp,extension_id,
product_code,prospect_name,prospect_email1,prospect_phone1,prospect_title,
prospect_company,prospect_message,track_id
FROM prospect_requests
WHERE subscriber_id = '$subscriberid'
AND create_timestamp >='$start_date'
AND create_timestamp <= '$end_date'");
There is two attributes names $start_date and $end_date
My question is why above query is not returning the information of $end_date
Here is scenario .
I have selected $start_date as 01-02-2013 and $end_date as 09-2-2013 .
But the above query is not returning the details of 9 Feburary .
Please help me out .
Update
When i am placing date as 10 feb it is returning me the details of 9 feb

Input : $start_time = 2013-02-01
$end_time = 2013-02-09

Answer 1

The condition <= '$end_date' is basically the same as <= '$end_date 00:00:00'.
If you need the day itself, you could query like this:
... create_timestamp <= '$end_date 23:59:59'
create_timestamp BETWEEN '$start_date' AND '$end_date 23:59:59' would work too.
Alternative
Add one day programmatically and use <:
$end_date = date('Y-m-d', strtotime("$end_date +1 day"));
... create_timestamp < '$end_date'
Update
You can also cast the timestamp to a date first:
DATE(create_timestamp) BETWEEN '$start_date' AND '$end_date'

Answer 2

Dates should be in the format YYYY-MM-DD.
Also, you can use WHERE create_timestamp BETWEEN '...' AND '...' as a more efficient condition for bounding a value.

Answer 3

for compare dates you should your BETWEEN Operator in mysql Query like Following
$result = mysql_query("SELECT
status,initiated_by,create_timestamp,extension_id,product_code,prospect_name,
prospect_email1,prospect_phone1,prospect_title,prospect_company,prospect_message,
track_id from prospect_requests WHERE subscriber_id = '$subscriberid' AND
create_timestamp BETWEEN '$start_date' AND '$end_date'");
Please full description of between operator at w2school
if still not working it then please update your question with table structure
i see your update question you are using timestamp field type that cause problem please see following link that might be helpfull Comparing timestamp with date variable (MySQL and PHP)
