    I have a table with over 70 million records. Columns are profileid(Table Index), email, lastname, first name, address1, address2, city, state, zip, country, phone1, phone2, gender, maritalstatus and spouse. When i run a simple query on that, it take 10 to 14 mins. How can i reduce query time?
    (a) With the help of re-organization of indexing
    (b) Partitioned views
    or any thing else

    Thanks in Advance

    View the execution plan of your query. It will tell you where the table or cluster scan is taking place. In most cases, adding an index to the column being scanned will help. But it is not always as simple as this, as you will need to consider all of the potential queries running against your table. You may also want to try the Index Wizard, as it is good for identifying needed indexes.
