| I found a good use for the Include. We have an 600,000 row table with an encrypted account number field. Users sometimes need to search on account number. The encrypted field is to big to be part of index key so SQL. To avoid SQL doing a table scan of 600,000 rows containing 100 or so fields, I created an index on the primary key and added the encrypted field to the include clause. This allows SQL to scan through all of the values much quicker than scanning the entire table. |
