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.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
