Mysql - Can I use WHERE and HAVING in the same query

Yes is the quick answer .  It's just about the order that you call the 'HAVING' or 'WHERE' up. 

Have a look at this webpage  How to call up HAVING and WHERE in the same MYSQL query  

So with the following statement

select id, user_id, cdate, start_time, end_time, count(*)
  from vfvi7_pf_time_tracking
  group by user_id, cdate
  having count(*) >1


I cannot put my WHERE clause at the end but need to put it before the GROUP BY; like this


select id, user_id, cdate, start_time, end_time, count(*)
  from vfvi7_pf_time_tracking
  WHERE dShftChked !=1
  group by user_id, cdate
  having count(*) >1
