Hi Experts,

Table info:

tickets(ticket_id,type,created time,issuetype_id(p.k of issuetype),subcategory_id(p.k of categories)
issuetype(id(p.k),code)
issuetypereport(id,issue_name,code)
categories(catid,name)

total ticket_id count
total issue_name like threshold(count)
total issue_name like down(count)
group by cat id

Thanks,

Try..

SELECT COUNT(*) AS TicketIdCount
 , SUM( CASE WHEN itr.issue_name LIKE '%threshold%' THEN 1 ELSE 0 END ) AS ThresholdCount								
 , SUM( CASE WHEN itr.issue_name LIKE '%down%' THEN 1 ELSE 0 END ) AS DownCount								
 , SUM( CASE WHEN itr.issue_name NOT LIKE '%threshold%' THEN 1 ELSE 0 END ) AS NOTThresholdCount								 
, SUM( CASE WHEN itr.issue_name NOT LIKE '%down%' THEN 1 ELSE 0 END ) AS NOTDownCount
FROM 
tickets t 
	INNER JOIN issuetype it ON t.issuetype_id = it.id
	INNER JOIN issuetypereport itr ON itr.code = it.code
	INNER JOIN categories c ON c.catid = t.subcategory_id
GROUP BY c.catid

@Pawan
Looks like he wants one count for custom so the last select in your sql would change to:
SUM( CASE WHEN (lower(itr.issue_name) NOT LIKE '%threshold%') and (lower(itr.issue_name) NOT LIKE '%down%')  THEN 1 ELSE 0 END ) AS CustomCount

Open in new window


Also note
  • I added lower function so case-sensitivy is not an issue
  • the table structure seems to be all in a 1-to-1 relationship, however, if that is not the case, this sql would not give proper results

Great ! Thanks Pierre. As of now I have assumed 1:1, will see if we get any issue there.

Updated code.

SELECT COUNT(*) AS TicketIdCount
, SUM( CASE WHEN itr.issue_name LIKE '%threshold%' THEN 1 ELSE 0 END ) AS ThresholdCount								
, SUM( CASE WHEN itr.issue_name LIKE '%down%' THEN 1 ELSE 0 END ) AS DownCount								
,SUM( CASE WHEN (lower(itr.issue_name) NOT LIKE '%threshold%') and (lower(itr.issue_name) NOT LIKE '%down%')  THEN 1 ELSE 0 END ) AS CustomCount
FROM 
tickets t 
	INNER JOIN issuetype it ON t.issuetype_id = it.id
	INNER JOIN issuetypereport itr ON itr.code = it.code
	INNER JOIN categories c ON c.catid = t.subcategory_id
GROUP BY c.catid

and the first 2 cases also need lower:
SELECT COUNT(*) AS TicketIdCount
, SUM( CASE WHEN lower(itr.issue_name) LIKE '%threshold%' THEN 1 ELSE 0 END ) AS ThresholdCount								
, SUM( CASE WHEN lower(itr.issue_name) LIKE '%down%' THEN 1 ELSE 0 END ) AS DownCount								
,SUM( CASE WHEN (lower(itr.issue_name) NOT LIKE '%threshold%') and (lower(itr.issue_name) NOT LIKE '%down%')  THEN 1 ELSE 0 END ) AS CustomCount
FROM 
tickets t 
	INNER JOIN issuetype it ON t.issuetype_id = it.id
	INNER JOIN issuetypereport itr ON itr.code = it.code
	INNER JOIN categories c ON c.catid = t.subcategory_id
GROUP BY c.catid

I agree a split point would have been better. I have no objection if you wish to reopen and reallocate points.
