Re: Cool but ugly SQL

So if I run this
select * from qtemp/srcmbrhash 
order by shh_lib, shh_file, shh_member, shh_lcdate desc,
         shh_lctime desc 

And get
....+....1....+....2....+....3....+....4....+....5....+....6....+....7
SHH_LIB     SHH_FILE    SHH_MEMBER  SHH_LCDATE  SHH_LCTIME  SHH_HASH 
MYLIB       MYFILE      MYMBR       2006-06-14   13:20:14   X347 
MYLIB       MYFILE      MYMBR       2006-06-11   15:20:14   X342 
********  End of data  ******** 

You want
select * from qtemp/srcmbrhash 
where (shh_lib, shh_file, shh_member, 
 timestamp(shh_lcdate, shh_lctime)) in 
(select shh_lib, shh_file, shh_member, 
 max(timestamp(shh_lcdate, shh_lctime)) 
 from qtemp/srcmbrhash 
 group by shh_lib, shh_file, shh_member)
....+....1....+....2....+....3....+....4....+....5....+....6....+....7
SHH_LIB     SHH_FILE    SHH_MEMBER  SHH_LCDATE  SHH_LCTIME  SHH_HASH 
MYLIB       MYFILE      MYMBR       2006-06-14   13:20:14   X347 
********  End of data  ********
