Hi I am using Stuff with XML Path for concatenating the data in multiple columns like city, town etc by Zip code. ie., unique column is Zip and all the cities will be concatenated to one cell, similarly town and so on. The query runs over 1 million data, table has 180 columns.I tried -
Adding indexes to the table, it took 50 minutes to run the query.
Added a temporary table to get only required 20 columns and added indexes to the temporary table and it helped reduce about 3 minutes.
Checked the execution plan the issue was with the table scan. There are no filters required to generate this report.
Can you please suggest what else could be done to improve.
Thanks

We need a LOT more details to offer much help. We would need to see the table with index definitions. The query you are running and the actual execution plan at a bare minimum.
