Hi,
I was creating a report based on a table in SQL Server and noticed that it was very slow. I realized that the problem was that the field/column used in selecting the records didn't have an index. I added an index on this field/column and report performs much better.
But I also noticed that this table has an identity field but it is not set as Primary Key. How important is it to set an identity column as a Primary Key (which of course will create the index)?
