Question

Here is my query:

SELECT count(*) 
  FROM table_testcase_execution 
 WHERE campaign_session_id = any(SELECT campaign_session_id 
                                   FROM table_campaign_session 
                                  WHERE campaign_session_name = 'sitename') 
   AND timestamp BETWEEN "1288929643485" AND "1289010305536"

This works just fine, the problem is that I have to use a LIKE on these because they contain 3 extra digits (so this is a timestamp plus 3 digits).

Therefore I am using a strtotime in php and trying to match these in the database, but they contain the extra 3 digits. Is there a way I can redo this sql or add a LIKE clause for each of these timestamps?

      "1288929643485" AND "1289010305536"

Something like

 SELECT count(*) 
   FROM table_testcase_execution 
  WHERE campaign_session_id = any(SELECT campaign_session_id 
                                    FROM table_campaign_session 
                                   WHERE campaign_session_name = 'sitename') 
    AND timestamp between LIKE "1288929643%" AND "1289010305%" 

Answer 1

Assuming that the 3 extra digits can range from 000 to 999 then you could do something like this:

select count(*) from table_testcase_execution
where campaign_session_id = any(
    SELECT campaign_session_id
    FROM table_campaign_session
    WHERE campaign_session_name = 'sitename')
AND timestamp >= "1288929643000" AND timestamp <= "1289010305999"

This along with an index in timestamp column should give you good performance.
