Hi everyone.

I create a method that get the last value of a table. But the order by desc is not working. I put the code and explain in detail

 In this example. I get a value (and it should be the last, but its the first ever) The “order by” clause its not working.

 

        public int getLastPhaseCode()
        {
            PXResult<CEPhaseCodes> res =
            SelectFrom<CEPhaseCodes>.OrderBy<CEPhaseCodes.phaseCode.Desc>.View.
            Select(this).FirstOrDefault();

            CEPhaseCodes p = (CEPhaseCodes)res;


            return (p != null) ? Convert.ToInt32(p.PhaseCode) : 0;
        }

Aditional.

CEPhaseCodes is my DAC/Table

 

Can you help me please!

Hi @eddiedaco  Yes, the above query is NOT working with the Order BY, please use the below code.

I just verified it and getting the expected value by using Order By Clause.

 

   public int getLastPhaseCode()
        {
            CEPhaseCodes p = SelectFrom<CEPhaseCodes>.OrderBy<CEPhaseCodes.phaseCode.Desc>.View.SelectWindowed(Base, 0, 1);

 
            return (p != null) ? Convert.ToInt32(p.PhaseCode) : 0;
        }
