Entity Framework (Telerik) call fails with ExecuteNonQuery to PostgreSQL stored procedure -

(postgresql 9.1, telerik openaccess v2.0.50727, pgadmin iii).

i'm having difficulty calling stored procedure (telerik) entity framework. exact error is:

npgsqlexception unhandled user code.

error: 42703: column "cpatient" not exist.

the telerik templated call is:

public int savedx(string cpatient, object o, object n)     {         oaparameter parametercpatient = new oaparameter();         parametercpatient.parametername = "cpatient";         parametercpatient.size = -1;         if(cpatient != null)         {             parametercpatient.value = cpatient;         }            else         {             parametercpatient.dbtype = dbtype.string;             parametercpatient.value = dbnull.value;         }          oaparameter parametero = new oaparameter();         parametero.parametername = "o";         parametero.value = o;          oaparameter parametern = new oaparameter();         parametern.parametername = "n";         parametern.value = n;          int queryresult = this.executenonquery("select * \"public\".\"g_savedx\"(cpatient, o, n)", commandtype.text, parametercpatient, parametero, parametern);          return queryresult;     } 

where executenonquery statement generates error. postgresql stored procedure is:

  function g_savedx(cpatient character varying, o view_dx, n view_dx)   returns void ... 

the postgresql function has been tested work correctly pgadmin.

so column "cpatient" coming from?? doing wrong?

i never telerik entitiesmodel executenonquery work under conditions. hence suggested code of:

        using (var cxt = new nova.data.data())         {             cxt.savedx();             cxt.savechanges();         } 

where cxt.savedx() domain model name postgresql g_savedx stored procedure, fails.

my eventual workaround postgresql use npgsql directly as:

  public void savedx(view_dx dx, bool alldx = false)     {         using (var cxt = new nova.data.data())         {             string connstring = cxt.connection.connectionstring;              using (npgsqlconnection conn = new npgsqlconnection(connstring))             {                 conn.open();                 using (var cmd = conn.createcommand())                 {                     cmd.commandtext = "g_savedx";                     cmd.commandtype = commandtype.storedprocedure;                     npgsqlcommandbuilder.deriveparameters(cmd);                     cmd.parameters["groupid"].value = ....                   var rowsaffected = cmd.executenonquery();                   }             }         }     } 

when doing way, use types defined in npgsqldbtype enumeration in postgresql procedure interface. (postgresql can use composite types, npgsql not much).

it sure nice telerik executenonquery work.
