http://blogs.msdn.com/b/sqlrbs/archive/2008/08/18/rbs-blobid-columns-in-application-tables-registering-and-indexing.aspxI recently got a question on RBS BlobId columns needing to have an index. This blog post expands on the answer.

Put another way, whoever calls rbs_sp_register_column, it is their responsibility to create the index before calling the SP. This is typically the case if you are writing a custom app or a packaged app yourself.</p> <p>If you are using an app written by somebody else, you need to consult with them to make any changes to the database. If the index is not already present, they should either update their product or give you a reason why they did not index it already. If you are using SharePoint, you are not allowed to modify the ContentDB (e.g. add/change indexes). SharePoint should create the index for you.</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=9986387" width="1" height="1">http://blogs.msdn.com/b/sqlrbs/archive/2008/08/18/rbs-blobid-columns-in-application-tables-registering-and-indexing.aspx#9986352Sun, 28 Mar 2010 10:11:57 GMT91d46819-8472-40ad-a661-2c78acb4018c:9986352Stiven<p>Pradeep</p> <p>Thanks for the posts.</p> <p>Just a question. Is this post suggesting that the index should be manually set or is it set by default?</p><div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=9986352" width="1" height="1">
