    Hi,

    I have a few stored procedures whose results do not map to a table in the database. In situations like this, it looks like the options are to retrieve the data from an object array that is returned, or create an empty view on the database and use it as the return type.

    Is it possible to manually create a persistent class in the data model that does not exist in the database, and can be used as the return type for a stored proc?

    Thanks.
    Chris

    Hi Zsolt,

    Defining a custom persistent class to preserve the results of a stored procedure is not currently supported by OpenAccess. You can define your class(non persistent) and have your own materialization logic as a workaround. I think that the easiest way to automate the workflow with OpenAccess would be to create database view that resembles the returned values by the stored procedure and then use that view as the return type of the stored procedure.

    Best wishes,
