Recently I visited a customer to do a SharePoint 2007 to 2013 upgrade and then I found some custom development in the databases.

Custom development

This was going to be an easy project and then I found the custom development. Someone had added some bits to the SharePoint database.

This customer created custom SQL views and SQL stored procedures in their SharePoint database. I knew this was unsupported but all seemed to be working ok until we tried to upgrade their 2007 Environment to 2007 SP2.

It just didn’t want to work. Errors similar to the following appeared in the upgrade log:

[SPManager] [ERROR] [6/24/2013 3:42:47 PM]: Upgrade [SPContentDatabase Name=My_Content Parent=SPDatabaseServiceInstance] failed.
[SPManager] [ERROR] [6/24/2013 3:42:47 PM]: Invalid object name ‘dbo.MyCustomView’.
[SPManager] [ERROR] [6/24/2013 3:42:47 PM]: at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)

at Microsoft.SharePoint.Upgrade.SPManager.Upgrade(Object o, Boolean bRecurse)

Looking at the upgrade.log (in 12/Logs) the problem was solved quickly.

The custom views and procedures didn’t use the dbo scheme. They used custom schemes. Sharepoint seems to collect all view names and then assumed the dbo scheme resulting in a view not found.

Painful for the customer. They had to delete all. Their custom views, procedures. Applications using the views/procedures failed and they had to realize that they had an unsupported SharePoint farm.
