Hi ,

Can anyone guide me to create index

This query performance very slow due to huge data.


select #wrk.*

FROM #wrk
		INNER JOIN #wrkBuildHierarchy
			ON BusinessEntityShortName = ParentName
		WHERE COBDate = @paramCOBDate
			AND RejectReason IS NULL

whether index to be created on only BusinessEntityShortName and
ParentName of the respective table

[or]

create index ind_1 on #wrk(BusinessEntityShortName ,COBDate,RejectReason)

Create a clustered index on (COBDate,RejectReason)
Create a non-cluster index on (BusinessEntityShortName)
Create a noe-cluster index on (ParentName)
