  • 0

I have a one class to one table mapping; unfortunately this table has 110+ columns, and queries take a long time process, especially when most of the time I only want to view <10 columns.

My problem is that the queries are dynamically generated based on what the user wants to look at. I can’t really create different mappings with different columns because there would be a very large number of combinations. I’m using the criteria API to generate the queries. Can I also use this to only select the columns the user wants? Or some other method?

Thanks

    Use a ProjectionList to select the columns you want. See here for the examples.
