I have the following SQL query:
select *
from NETWORK n
inner join vwNETWORK_KEYMSTN km on n.Network_ID = km.Network_ID
inner join vwAPPROVAL_LATEST a on n.Network_ID = a.Network_ID
inner join APPROVAL_VINTAGE av on a.Approval_ID = av.Approval_ID and km.Milestone_Type_ID = av.Milestone_Type_ID
inner join NETWORK_MILESTONE m on A.Approval_ID = m.Approval_ID and km.Milestone_Type_ID = m.Milestone_Type_ID
inner join REF_MILESTONE rm on km.Milestone_Type_ID = rm.Milestone_Type_ID
inner join NETWORK_STATUS s on n.Network_ID = s.Network_ID --and s.Status_Type_ID = 2
--where rm.Status_Type_ID = s.Status_Type_ID
This query returns in about 6s. The last table, NETWORK_STATUS, causes my result set to split out. That is, n.Network_ID would be unique before adding that last table NETWORK_STATUS to the join.
Adding the join clause that is currently commented out will return a unique set of Network_ID again. The commented out join will a result set in fast time, ie, < 10s.
However, what I truly want is the where clause that is commented out, or I could put it as part of the join. A MILESTONE_type is associated with only one STATUS_type. Putting this part in, which is seemingly a trivial addition to the query, causes a massive explosion in run time... I kill the query after a minute, but it could be even greater than a 6x factor increase in run time.
My question to this forum is why that might be the case, and more importantly, how do I tell SQL Server that this really isn't a hard where clause to execute. At most, the where clause should return in < 20s... it could return the full set with duplicates (~6s), and then 2nd pass simply trim out the rows that don't satisfy the where clause.
Execution Plan: here is the problem line:
