RE: CYMD dates and SQL

["Goodbar, Loyd (AFS-Water Valley)" <LGoodbar@xxxxxxxxxxxxxx>]

I have created a process for CYMD2DATE and DATE2CYMD. Unfortunately, without
a C compiler, I cannot create user-defined functions to use them.... The
create function... parms may not be exactly right, as I was reading through
the programming manual while writing them. However, the code inside the
return() is correct. Cymd2date() assumes the size of an integer is 10. These
routines are not optimized (especially cymd2date()).

create function date2cymd(indate date) returns integer
language sql
deterministic
begin
return(
   cast(
      strip(char(int(substr(char(year( indate )),1,2))-19))||
      substr(char( indate ,iso),3,2)||
      substr(char( indate ,iso),6,2)||
      substr(char( indate ,iso),9,2)
   as integer)
);
end

create function cymd2date(incymd integer) returns date
language sql
deterministic
begin
return(
   date(
      strip(char((int(substr(substr(digits( incymd ),4,7),1,1))
         +19)))||
      substr(substr(digits( incymd ),4,7),2,2)||'-'||
      substr(substr(digits( incymd ),4,7),4,2)||'-'||
      substr(substr(digits( incymd ),4,7),6,2)
   )
);
end

Can someone with SQL development kit and C compiler compile these functions
and verify they compile and work? Are the functions standalone objects that
could be saved and emailed?

Select date2cymd(curdate()) ... Should return 1,020,802
Select date2cymd(date('1999-12-31')) ... Should return 991,231
Select cymd2date(1020802) ... Should return 08/02/02 (USA)
Select cymd2date(0991231) ... Should return 12/31/99 (USA)

Thanks,
