I have a stored procedure that search a view using full text.
I’m trying to map the results to an existing Entity (Sales), where I mapped the column MivType to SaleType (as it makes more sense, and I want to keep db names away from my web site). The stored procedure is mapped to a Function Import, and I’ve defined its ReturnType to Sales.
This work well as long as the entity has the same property names as fields names.

Here’s my problem: when I change the property’s name, I get the following error after running the imported function:

The data reader is incompatible with the specified ‘Model.Sale’. A member of the type, ‘SaleType’, does not have a corresponding column in the data reader with the same name.

I can fix this if I change the property ‘SaleType’ to ‘MivType’ on the entity, but why should I do that? Isn’t that what the mapping is for?
This means I have to use the exact same names on the stored procedure and the entity, so in effect, the mapping is ignored (I have names like YzrName, MivYaad, etc, and I don’t like it).
Is there a simple way around this? I don’t want to use the db names on my application, and prefer not to change the stored procedure…
(I should mention I’m a beginner with the EF, so this can be a rookie mistake)

Thanks.

    Well the entity designer doesnt work very well. I generally try to do everything in the XML. In the XML there are 3 parts. The Storage (a representation of the SQL Database). The Conceptual (a represention of your .Net Objects. and the Conceptual to Storage Mapping

    It sounds like the error is in your Conceptual to Storage Mapping. You can keep the property name SalesType on the conceptual side but the mapping must map the the correct names on both the conceptual and storage side.

    Refer to MSDN here are some articles
