Good afternoon all...

I have a table containing 72 million records. It's taking a while to delete a set of records from the table. The WHERE clause in my delete statement is base on two columns with each having a separate index. Is there any advantage in creating a new index based on the two columns in order to speed up the delete process?

Your advice would be greatly appreciated.

No, indexes will slow your delete down, not speed it up as each index will need to be searched and updated as well as the rows being deleted..
