  1. On Addition to the above points, i would like to suggest ,
    Practice proper use of CASE statements.
    Try to avoid using, Updates to temporary tables or unnecessary UNION’s in your Query. Instead practice proper use of CASE.

  2. As most of us are using SQL server Management Studio Express IDE, its easy to see the execution plan and missing indexes. In the tool bar itself there is an icon that says ‘Include Actual Execution plan (Ctrl + M)’. You can use it to measure the performance of query.
