I recently had to create a occasionally offline application and decided to use the synchronization feature provided in VS2010. I hence studied a bit about SQL CE and decided to test out the features provided within.
Since I use an object datasource due to a framework most of my DB objects had already been mapped out from SQL SERVER 2008 R2 DB.
I first encountered a problem when dealing with Views, since CE doesnt support them, so I decided to test out a few SELECT statements I took from our internally used views and run them directly through the query analyser of VS 2010 and I was happy to verify they worked properly.
So I began the exaustive work of adapting the Framework to store the SELECT STATEMENT that defined the view and use it only when connected to a CE database, ofc I also decided to try it in 1 of the more complex views first. The same one I had tested against the query analyser. And to my surprise running it in my framework throws an error 'Invalid Column Name'. For Column 'PlusAreaOperationIdPlusAreaOperation'.
Anyone has any ideas on how to address this situation? I'm willing to create a sample online DB with the required structure for anyone to replicate the error elsewhere. Just mail me asking for the details.
Again: This query runs fine when using query analyser within VS2010 but it fails when executing a datareader.
