Had Tennyson been a Technical Author First published 16 July 2006 Phil gives reign to his inner poet, documenting the SQL Server index in the style of Lord Alfred Tennyson. I have always wondered why nobody has written a book on SQL Server in verse. To correct this lamentable gap in the market, I have been penning some stanzas. Here, as a sample, is a short verse on indexing. The Index: An Elegy An index is used as a short-cut to data a table will warrant one sooner or later Because only one can be clustered, beware and ponder the index you cluster with care. The issues are clearer than you might suppose this index determines the order of rows so searching the index requires less I/O. Selecting the column on which it should go depends on the way that the rows are selected, which should become clear if the Schema's inspected. One problem, however, I think you should know, retrieving a range can be horribly slow. A non-clustered index is almost as good once ordering keys can be well understood make sure that the columns you use are selective for if too few values, it's most ineffective. If data is changing or updating too
240 Had Tennyson been a Technical Author with frequent insertions, keep indexes few. From 2000 on you can index a view (but then there's restrictions on what you can do) and even on computed columns as well but only if deterministic as hell. For reasons which often are misunderstood a non-clustered covering index is good when composite columns are used with some care they outperform anything else that's out there.
