entity framework - The type Parameter in Execute Function is incompatible with the type returned by the function -

-

i'm getting following error when trying import stored proc function in entity framework 5. have updated data project reference new version of ef.

the type parameter 'ssds.data.testy_result' in executefunction incompatible type 'ssds.data.testy_result' returned function.

i can't work stored proc...here simple test one:

create procedure testy  begin     select 'hello' hello end go

it breaks exception above here:

 public virtual objectresult<testy_result> testy()     {         return ((iobjectcontextadapter)this).objectcontext.executefunction<testy_result>("testy");     }

and there no error when set result string scalar in edit function import window in model designer.

i'm calling function this:

private entities db = new entities(); var x = db.testy();

is there obvious i'm missing here? there few edmx files in project , others created older version of ef (and use objectcontext).

function mappings:

more function mappings detail:

testy_result class:

  public partial class testy_result     {         public string hello { get; set; }     }

i've been struggling same problem last few days. project had been upgraded previous version of entity framework 5.0. figured out due having mix of old , new edmxs. removing old edmx allowed new 1 work, of course that's not viable solution. able work changing code generation strategy new (ef 5) edmx "legacy objectcontext". if you're not familiar, can found opening edmx diagram, right-clicking, , going properties. suspect edmxs in project need on same code generation strategy, change old ones t4 instead, although involve more work.

What is the difference between data design and data model(ERD) -

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
