Hi
I have one table that I run a query on - it currently has around 30 million rows and growing daily by around 300,000 rows. The table has one Clustered index on the date field.
In my reporting tool which interrogates this table I have 4 filters - primarily in the following order.
Date (hence Clustered index on date)
Country
Region
Gender

Could I improve performance by adding indexes for Country, Region and Gender - or is the Clutsered date index sufficient?

Regards
