    <p>I think I'd still stick with a bulk insert approach. You may find that tempdb still gets hit using a TVP with a reasonable number of rows. This is my gut feeling, I can't say I've tested the performance of using TVP (I am interested in hearing others input too though)</p> <p>You don't mention if you use .NET, but the approach that I've taken to optimise previous solutions was to do a bulk load of data using the <a href="http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlbulkcopy.aspx" rel="nofollow noreferrer">SqlBulkCopy</a> class - you don't need to write the data to a file first before loading, just give the <a href="http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlbulkcopy.aspx" rel="nofollow noreferrer">SqlBulkCopy</a> class (e.g.) a DataTable - that's the fastest way to insert data into the DB. 5-10K rows isn't much, I've used this for up to 750K rows. I suspect that in general, with a few hundred rows it wouldn't make a vast difference using a TVP. But scaling up would be limited IMHO.</p> <p>Perhaps the new <a href="http://technet.microsoft.com/en-us/library/bb510625.aspx" rel="nofollow noreferrer">MERGE</a> functionality in SQL 2008 would benefit you?</p> <p>Also, if your existing staging table is a single table that is used for each instance of this process and you're worried about contention etc, have you considered creating a new "temporary" but physical staging table each time, then dropping it when it's finished with?</p> <p>Note you can optimize the loading into this staging table, by populating it without any indexes. Then once populated, add any required indexes on at that point (FILLFACTOR=100 for optimal read performance, as at this point it will not be updated).</p>

    1. COI do use .NET, and the process happens to predate `SqlBulkCopy` and has simply never been changed. Thanks for reminding me about that, it may be worth revisiting. `MERGE` is also already used extensively, and temporary tables were tried once before but found to be slower and more difficult to manage. Thanks for the input!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
