Hello all -

How do I add the condition to look for Quarter 3 earn in case if the 4th Quarter earn is null (WORK_PERIOD is char 200501….).

Here is my select for Q4 only:

Code: 
SELECT 
	MEMBER_WORK_PERIOD.MEMBER_KEY 
	, MEMBER_WORK_PERIOD.EMPLOYER_NO 

	, SUM ( CASE WHEN WORK_PERIOD IN ( '200510','200511','200512')  
	 and funds_05.fund  NOT in 	('DFH','CAH','66LH','L108H','TOGH')

	THEN QUANTITY END) AS Q4_EARN  

  	, SUM ( CASE WHEN WORK_PERIOD IN ( '200510','200511','200512') and funds_05.fund in
	('DFH','CAH','66LH','L108H','TOGH') THEN (cast (RATE as float)) END ) AS Q4_FLAT_EARN   

	, MEMBER_WORK_PERIOD_FUND.APP 
	, MEMBER_WORK_PERIOD_FUND.FUND 

FROM 	
	MEMBER_WORK_PERIOD_FUND
	, MEMBER_WORK_PERIOD 
	, FUNDS_05 

	WHERE MEMBER_WORK_PERIOD_FUND.MVPOS=MEMBER_WORK_PERIOD.MVPOS 
	AND MEMBER_WORK_PERIOD.MEMBER_KEY=MEMBER_WORK_PERIOD_FUND.MEMBER_KEY 
	AND  
	MEMBER_WORK_PERIOD_FUND.FUND =   FUNDS_05.fund
	and fund_desc='H'
	and WORK_PERIOD ( '200510','200511','200512') 

[red]---?????( '200507','200508','200509') ???? [/red] 
        
	GROUP BY 
		  MEMBER_WORK_PERIOD.EMPLOYER_NO 
		, MEMBER_WORK_PERIOD.MEMBER_KEY 
		, MEMBER_WORK_PERIOD_FUND.APP 
		, MEMBER_WORK_PERIOD_FUND.FUND
Thanks,
Cristi.

Your where clause could contain 3rd an 4th quarter, and then you case statement could sort out the rest:
Code: 
Where ...
and work_period in ('200507','200508','200509','200510','200511','200512')
Code: 
select ...
    , SUM ( CASE WHEN WORK_PERIOD IN ( '200510','200511','200512')  
     and funds_05.fund  NOT in     ('DFH','CAH','66LH','L108H','TOGH')

    THEN QUANTITY END) AS Q4_EARN  

      , SUM ( CASE WHEN WORK_PERIOD IN ( '200510','200511','200512') and funds_05.fund in
    ('DFH','CAH','66LH','L108H','TOGH') THEN (cast (RATE as float)) END ) AS Q4_FLAT_EARN,
    , SUM ( CASE WHEN WORK_PERIOD IN ( '200507','200508','200509')  
     and funds_05.fund  NOT in     ('DFH','CAH','66LH','L108H','TOGH')

    THEN QUANTITY END) AS Q3_EARN  

      , SUM ( CASE WHEN WORK_PERIOD IN ( '200507','200508','200509') and funds_05.fund in
    ('DFH','CAH','66LH','L108H','TOGH') THEN (cast (RATE as float)) END ) AS Q3_FLAT_EARN

thanks for your time, but

i need to select all q4 & if there is nothing in q4 than select q3, the above logic will pick both qts...??

i need to incorporate something like this into the select:

when q4 is null than select ... * from .... where q4 is null & q3 is not null

Would the following variation do what you want?
Code: 
SELECT 
  MEMBER_KEY 
  , EMPLOYER_NO 
  , COALESCE(Q4_EARN,Q3_EARN)  
  , COALESCE(Q4_FLAT_EARN,Q3_FLAT_EARN)

  , MEMBER_WORK_PERIOD_FUND.FUND

SELECT 
    MEMBER_WORK_PERIOD.MEMBER_KEY 
    , MEMBER_WORK_PERIOD.EMPLOYER_NO 
    , SUM(CASE WHEN WORK_PERIOD IN ( '200510','200511','200512')  
        and funds_05.fund  NOT in ('DFH','CAH','66LH','L108H','TOGH')
        THEN QUANTITY END) AS Q4_EARN,  
    , SUM(CASE WHEN WORK_PERIOD IN ( '200510','200511','200512') and funds_05.fund in
      ('DFH','CAH','66LH','L108H','TOGH') 
      THEN (cast (RATE as float)) END ) AS Q4_FLAT_EARN   
    , SUM(CASE WHEN WORK_PERIOD IN ( '200507','200508','200509')  
        and funds_05.fund  NOT in ('DFH','CAH','66LH','L108H','TOGH')
        THEN QUANTITY END) AS Q3_EARN,  
    , SUM(CASE WHEN WORK_PERIOD IN ( '200507','200508','200509') and funds_05.fund in
      ('DFH','CAH','66LH','L108H','TOGH') 
      THEN (cast (RATE as float)) END ) AS Q3_FLAT_EARN

no, i need something like this incorporated in the select
Code: 
SELECT a.member_key, a.q4_earn,
(case when a.q4_earn  is null then a.Q3_EARN else a.q4_earn end ) as q4
 FROM HEALTH_GRP a left outer join HEALTH_GRP b
on b.q4_earn is null and b.Q3_EARN is not null
and a.q4_earn is not null 
where a.fund not in ('DFH','CAH','66LH','L108H','TOGH')

union

SELECT a.member_key, a.q4_flat_earn
,(case when a.q4_flat_earn  is null then a.Q3_flat_EARN else a.q4_earn end ) as q4_flat
 FROM HEALTH_GRP a left outer join HEALTH_GRP b
on b.q4_flat_earn is null and b.Q3_flat_EARN is not null
and a.q4_flat_earn is not null 
where a.fund  in ('DFH','CAH','66LH','L108H','TOGH')

Alternatively you could use a union and a not exists clause:
Code: 
select ...
from ...
Where ...
  and work_period in ('200510','200511','200512')

Union

select ...
from ...
Where ...
  and work_period in ('200507','200508,'200509;)
  and not exists (
    select 1 
    from ...
    where ...
      and work_period in ('200510','200511','200512'))
The from clause and where clause in the "not exists" sub-query should match the from and where clause from the first query in the union.

I posted my last suggestion before I saw your response. A timing thing.

That looks like what I had in mind. What happens when you try it?

Expected tokens may include: "BETWEEN". SQLSTATE=42601

replace "and not not exists (" with "and not exists". You had an extra not.

You are also missing a 'close bracket' at the end of your last not exists.

and WORK_PERIOD in ('200510','200511','200512'))
