Ensure there is sufficient indexing (clustered or non-clustered) if the temp table is used within the inner join , group by , order by or where conditions. Impact on CPU utilization due to Cxpacket waits resulting from insufficient indexing on temp tables that can be mitigated if temp tables are well indexed with clustered and non-clustered indexes

Any help provided would be most appreciated

If data is huge, if there are any Non-Clustered indexes that are not build on primary key or unique key, then disable those indexes, loading will be much faster. How can I fix? I have SQL Server 2008 and Visual Studio 2008 and am trying to automatically insert new records into a child table based on new inserts into its parent table
