Select from SubQuery
I have code that is inserting records into a temp table, Then using that those records in a second query:
select distinct(CASE_NO) into #Temp_Case_Attach_nlto
from Case_Attachments
where CASE_NO in
(select CASE_NO from Case_Actions
where CASE_NO in (select CASE_NO from Case_Main
where STARTED >='2015-06-01' and STARTED <= '2015-06-30'))
and DESCRIPTION like '%nlto%' --(43 row(s) affected)
select * from #Temp_Case_Attach_nlto
where CASE_NO not in
(select distinct(CASE_NO) from Case_Attachments
where CASE_NO in
(select CASE_NO from Case_Actions
where CASE_NO in (select CASE_NO from Case_Main
where STARTED >='2015-06-01' and STARTED <= '2015-06-30'))
and DESCRIPTION like '%nov%') -- 41 include this first section with the and
and CASE_NO not in
(select CASE_NO from Case_Main
where STATUS = 'UNFOUNDED') --41 ---Use this number for cases resolved voluntarily
drop table #Temp_Case_Attach_nlto
I want to create a query that will allow me to do the second query getting a count without using a temp table something like:
SELECT Distinct COUNT(*)
from
(SELECT Distinct CASE_NO
FROM Case_Attachments
Where DESCRIPTION like '%nlto%'
and CASE_NO in
(Select CASE_NO from Case_Actions
Where CASE_NO in (Select CASE_NO from Case_Main
Where STARTED >= '2015-06-01' and STARTED <= '2015-06-30')))
Where CASE_NO not in
(select distinct(CASE_NO) from Case_Attachments
where CASE_NO in
(select CASE_NO from Case_Actions
where CASE_NO in (select CASE_NO from Case_Main
where STARTED >='2015-06-01' and STARTED <= '2015-06-30'))
and DESCRIPTION like '%nov%')
and CASE_NO not in
(select CASE_NO from Case_Main
where STATUS = 'UNFOUNDED')
HOWEVER, It does not like the where clause after the select from.
select distinct(CASE_NO) into #Temp_Case_Attach_nlto
from Case_Attachments
where CASE_NO in

Define 'not like', preferably with an error statement. Doesn't get invited to the 'cool' parties? Doesn't get invited to the 'cabin Up North' to see the family and go water skiing?
When you execute the query in SSMS, does return an error message? If yes, copy-paste it into this question, and click on the error message, watch the cursor jump to the offending line, and tell us what line that is.
btw That's a wompload of nested subqueries in the WHERE clause you have there.

and if STARTED is a datetime, then the above would not return any rows with 2015-06-30 and a time component, so use this instead

try:
SELECT DISTINCT cm.CASE_NO
FROM Case_Main cm
/*
INNER JOIN Case_Actions ca
ON cm.CASE_NO = ca.CASE_NO

INNER JOIN Case_Attachments catt
ON cm.CASE_NO = catt.CASE_NO

AND catt.DESCRIPTION LIKE '%nlto%'
and cm.STATUS <> 'UNFOUNDED'
;
There is never a time component. I am working with older code, trying to rewite. I will try Pauls answer. Thanks for all of your help.
I think the more efficient query below will give you an accurate result, based on your stated requirements and the queries given:
SELECT COUNT(*) AS Final_Count
FROM (
SELECT cm.CASE_NO
FROM Case_Main cm
WHERE cm.STARTED >='20150601' and cm.STARTED < '20150701'
GROUP BY cm.CASE_NO
HAVING
SUM(CASE WHEN cm.DESCRIPTION like '%nlto%' THEN 1 ELSE 0 END) >= 1 AND
SUM(CASE WHEN cm.DESCRIPTION like '%nov%' THEN 1 ELSE 0 END) = 0 AND
SUM(CASE WHEN cm.STATUS = 'UNFOUNDED' THEN 1 ELSE 0 END) = 0
) AS subquery1
SELECT COUNT(*) AS Final_Count
FROM (
SELECT cm.CASE_NO
FROM Case_Main cm
WHERE cm.STARTED >='20150601' and cm.STARTED < '20150701'
GROUP BY cm.CASE_NO
HAVING
SUM(CASE WHEN cm.DESCRIPTION like '%nlto%' THEN 1 ELSE 0 END) >= 1 AND
SUM(CASE WHEN cm.DESCRIPTION like '%nov%' THEN 1 ELSE 0 END) = 0 AND
SUM(CASE WHEN cm.STATUS = 'UNFOUNDED' THEN 1 ELSE 0 END) = 0
) AS subquery1
i got 0. i should get 36. I will play with it and see if I can make adjustments to get a good result.
I went back to Paul's query and added some code. It worked. But maybe I could get some suggestions on a better way to do it.
SELECT DISTINCT cm.CASE_NO
FROM Case_Main cm
/*

Sorry, I overlooked that the DESCRIPTION was coming from the case_attachments table. But easy enough to join that table in (I had anticipated some type of join being needed, that's why I used a table alias in the query):
SELECT COUNT(*) AS Final_Count
FROM (
SELECT cm.CASE_NO
FROM Case_Main cm
INNER JOIN Case_Attachments catt ON
catt.CASE_NO = cm.CASE_NO

SUM(CASE WHEN catt.DESCRIPTION like '%nlto%' THEN 1 ELSE 0 END) >= 1 AND
SUM(CASE WHEN catt.DESCRIPTION like '%nov%' THEN 1 ELSE 0 END) = 0 AND
SUM(CASE WHEN catt.STATUS = 'UNFOUNDED' THEN 1 ELSE 0 END) = 0

Observation:
You seem to have a tendency to use IN ( some-query-here )
e.g.
and CM.CASE_NO not in
(select Case_Main.CASE_NO from Case_Main, Case_Attachments
where CASE_MAIN.CASE_NO = Case_Attachments.CASE_NO
And STARTED >='2015-06-01' and STARTED <= '2015-06-30'
and Case_Attachments.DESCRIPTI
Try to avoid this temptation
This might be difficult.
While using IN( ... ) isn't always bad, so far in this question each time there has been a more direct/more efficient alternative.

I tried your last query:
SELECT COUNT(*) AS Final_Count
FROM (
SELECT DISTINCT cm.CASE_NO
FROM Case_Main cm
INNER JOIN Case_Attachments catt ON
catt.CASE_NO = cm.CASE_NO
WHERE cm.STARTED >='20150601' and cm.STARTED < '20150701'
AND cm.STATUS <> 'UNFOUNDED'
AND catt.DESCRIPTION like '%nlto%'
AND NOT catt.DESCRIPTION like '%nov%'
) AS subquery1
It does not work. It stillretrieves all of the records (45), when it should get 36.
I would prefer not to use IN, but I was looking for something that would work. So that is why I posted that solution and then asked if there was a better way, since I did not know one. I do appreciate all the help I have obtained on this site.

I thought there might be a way to do it with a left join and then look for a null, but I could not figure out exactly how to write it.
OK, using GROUP BY and HAVING removes some that a where clause does not, so try this one please
SELECT COUNT(*) AS Final_Count
FROM (
SELECT cm.CASE_NO
FROM Case_Main cm
INNER JOIN Case_Attachments catt ON
catt.CASE_NO = cm.CASE_NO
WHERE cm.STARTED >='20150601' and cm.STARTED < '20150701'
AND cm.STATUS <> 'UNFOUNDED'
GROUP BY cm.CASE_NO
HAVING SUM(CASE WHEN catt.DESCRIPTION like '%nlto%' THEN 1 ELSE 0 END) >= 1
AND SUM(CASE WHEN catt.DESCRIPTION like '%nov%' THEN 1 ELSE 0 END) = 0
) AS subquery1
SELECT COUNT(*) AS Final_Count
FROM (
SELECT cm.CASE_NO
FROM Case_Main cm
INNER JOIN Case_Attachments catt ON
catt.CASE_NO = cm.CASE_NO
WHERE cm.STARTED >='20150601' and cm.STARTED < '20150701'
AND cm.STATUS <> 'UNFOUNDED'
GROUP BY cm.CASE_NO
HAVING SUM(CASE WHEN catt.DESCRIPTION like '%nlto%' THEN 1 ELSE 0 END) >= 1
AND SUM(CASE WHEN catt.DESCRIPTION like '%nov%' THEN 1 ELSE 0 END) = 0
) AS subquery1
