Join Martin Guidry for an in-depth discussion in this video Indexing tips, part of SQL Server 2012: Designing Database Solutions.
- Now I'd like to give you a few tips…on designing indexes in SQL Server in 2012.…We typically want to index all foreign keys,…any field that's used in a join;…the join can typically run much quicker…if all fields used in the join have an index.…We typically see good benefit from indexing columns…that are commonly used in the…WHERE, ORDER BY, or GROUP BY clause…in a SQL statement.…These are all clauses that are commonly used in reports…so if you have a lot of reports…that always ORDER BY a certain column…it would probably benefit you…to create an index on that column.…
You should also be aware of how…the Query Optimizer chooses indexes…to use on a table.…It will typically only use an index on a field…if that field stands alone.…Let's look at an example…where a field does not stand alone.…Here we're running the YEAR function…on a column called (myDate)…and looking for any situation where the YEAR is >= 2012.…In this example the (myDate) does not stand alone;…the (my Date) is part of a function.…
And therefore the Query Optimizer…
