This is a stored proc that will move your indexes to two new file groups. A Cindex file group is for the clustered indexes and NCindex file group is for non clustered indexes. The parameters for this procedure are @CPATH - the path to the clustered index datafiles @NCPATH - the path to the nonclustered […]

We’ve all seen reindex procedures that rebuild all indexes in a database or all indexes in a database which have less than a specified ScanDensity. This one goes a few steps further. First, the DBA can specify a ScanDensity_Threshold (a min value for ScanDensity), plus a Limit (qty or %). If you specify a ScanDensity_Threshold […]

When it comes to auditing index use in SQL Server databases, I sometimes get overwhelmed. For example, how to do you go about auditing indexes in a database with over 1,500 tables? While auditing a single index is relatively straight-forward, auditing thousands of them in multiple databases is not an easy task. Whether the task is easy or not, it is an important task if you want to optimize the performance of your SQL Server databases.

There is nothing spectacular about using indexes per say. However, on many occasions I have come across a variety of SQL coders that never consider validating that the index they think they are using is efficient or even being used at all. We can all put indexes on the columns that we think will be required to satisfy individual queries, but how do we know if they will ever be used. You see, if the underlying table data is constructed, contains, or is ordered in a particular way, our indexes may never be used. One of the factors around the use of an index is its clustering factor and this is what this article is about.

SQL Server depends heavily on good indexing to perform well. The optimizer requires relevant and intelligent indexing in order to do its job well. Author Andre Vigneau brings us a script that he uses to detect possible index problems in the database design as well as a number of hints to ensure that your database is performing optimally.

Indexing performance has always been the Achilles' heel of SQL Server's full-text feature. Although the search performance itself is fast (very few customers complain about the search speed), users do complain (often loudly and frequently) about how slow the indexing process is–especially for large tables. Here's a few tips for you.

To help maintain index quality, defragging of any given index is a good thing. This will defrag ALL indecies in the current DB. NOTE: Schedule for off-hours operations. For a massive re-write of indecies, change the remarking on "--IF @indid" lines to use reindex instead of just defragging.
