I've got a query that is running very slowly. In the execution plan it says that a Hash Match (Full Outer Join) is taking up 60% of the cost. I also ran they query through the tuning advisor and applied the recommended changes but it still runs very slow.

Can anyone point me in the rigth direction as to where to begin to solve this problem?

Thanks,

Matt

If it helps here is the query

select coalesce(d.systemCode, a.systemCode, w.systemCode, m.systemCode) as 'System Name',

Do you really need all these columns in the GROUP BY?

group by w.systemcode, w.taxdate, w.systemcode, w.icunumber, w.icuname, w.planid, w.icuname,
w.planname, w.ssn, w.tradedate, w.supersheetdate, w.statecode, w.vehiclenumber, w.vehiclename,
w.externalaccount, d.ssn, d.supersheetdate, d.systemcode, d.icunumber, d.icuname, 
d.vehiclenumber, d.planid, d.planname, d.externalaccount, d.tradedate, d.statecode, 
d.participantname, d.confirmdate, d.withholdingamount, d.statewhamount, a.ssn,a.systemcode, 
a.supersheetdate, a.icunumber, a.icuname, a.vehiclenumber, a.planid, a.planname, 
a.participantname, a.externalaccount, a.tradedate, a.amount, m.systemcode, m.taxdate, 
m.icunumber, m.icuname, m.planid, m.planname, m.ssn, m.tradedate, m.supersheetdate, 
m.statecode, m.participantname, m.vehiclenumber, m.vehiclename, m.externalaccount, 
m.confirmdate, m.withholdingamount, m.statewhamount

You have only 15 non-aggregated columns in the SELECT part.

Should/can I use coalesce in the group by?

But the query will still run slow because of all the bindings in the JOINs...

Which index do you have on the tables?
