i using entity framework 5.0 work oracle 11g... please guys

edit: here have:

var last = qu.concat<object>(sm_list);

give me error: system.argumentexception: dbunionallexpression requires arguments compatible collection resulttypes

note qu , sm_list not same type nor implement same interface.

"note qu , sm_list not same type nor implement same interface."

and that's error message complains of: 

dbunionallexpression requires arguments compatible collection resulttypes

you need make 2 result sets have same projection before can concatenate them. can either adding dummy elements first collection (and populating them null or empty strings or whatever) or else excluding columns second collection.
