Hint Details:

When determining the Start Date of a Subcontract Unit, should that item have been transferred, then the start date of the 'live' subcontract record is not tsub contract start date of the unit trail, or the customer's actual first move-in date.

When determining the length of stay for an individual customer's contract item, for example, it may not have been originally moved in on the same date as the contract was created, so you might get an incorrect result when trying to determine the actual customer move in date.

To do this, we would need to follow the trail of transfers in order to find the original subcontract record to get the right start date.

The function below does this for you;

Pass a SubcontractID and the date returned is the original move in subcontract record's start-date, no matter how many time the unit may have been transferred:

create FUNCTION "spaceman"."GetSubcontractStartDate" 
(in iSubid char(20))
returns date
begin
  declare thisstartdate date;
  declare nextsubid char(20);
  select Startdate,transferedfrom into thisstartdate,nextsubid from subcontract where subcontractid=iSubid;
  while nextsubid is not null loop
      select Startdate,transferedfrom into thisstartdate,nextsubid from subcontract where subcontractid=nextsubid
  end loop;
  return(thisstartdate)
end
