  • Maybe something like this?

        var res1 =
    	from c in Table
    	select new
    		c1 = c.Column1,
    		c2id = (int?)c.Column2ID,
    		c3id = (int?)c.Column3ID,
    		c4id = (int?)null
    	var res2 =
    	from c in Table
    	select new
    		c1 = null,
    		c2id = (int?)null,
    		c3id = (int?)c.Column3ID,
    		c4id = (int?)c.Column4ID
    	var result =
    	r1.Union( r2 );

  • Hi seco,

    Does these two query results have common properties or columns ? Could you please post the code for these two queries ? Thank you.

    Best regards,

  • Well, not sure if will work for you or even if is a good idea but any query return a IEnumerable and every element of it is a record of the table who match the condicion.  You could use Zip<> to merge the two query results into one using  a predicate function that format each element.

    You have to be a bit more specific if you want code.

    Sorry if it was not helpfull.
