Hi,

Have a table called tbl1 like :

UPDATEDATETIME       dBDate               HFCol      HVCol
3/10/2011 13:06:53       6/10/2011      10369.8      0.1979
3/10/2011 13:06:53       3/11/2011      10440      0.2059
3/10/2011 13:07:03       6/10/2011      10369.8      0.1976
3/10/2011 13:07:03       3/11/2011      10440      0.2036
3/10/2011 13:07:13       6/10/2011      10369.8      0.1975
3/10/2011 13:07:13       3/11/2011      10440      0.2038

and struggling to get sql/sotre proc to produce following results:

UPDATEDATETIME      HFCol_JUN11      HFCol_MAR11       HVCol_JUN11       HVCol_MAR11
3/10/2011 13:06:53      10369.8             10440               0.1979               0.2059
3/10/2011 13:07:03      10369.8             10440               0.1976               0.2036
3/10/2011 13:07:13      10369.8              10440               0.1975               0.2038

[As you can see new columns in result are old columns and month and year from dbDate is appended. For eg. HFCol for dbDate 03/11/2011 becomes HFCOL_MAR11 etc.]
                        
Thanks,

it's a pivot table ... must it be fully dynamic, or are you happy with those 2x2 columns?

hi angelll,
it should be dynamic.
One more note, as you can see what I'm trying to do is trying to put data for same UPDATEDATETIME  into one row.

Thanks

could the data be over 1 year? how to represent that?
also, could there be more than 1 row per "month" ?

let's assume for the moment that it was all from 1 year
select UPDATEDATETIME       
  , max(case when month(dBDate) = 1 then  HFCol else null end) HFCol_Jan
  , max(case when month(dBDate) = 1 then  HVCol else null end) HVCol_Jan
  , max(case when month(dBDate) = 2 then  HFCol else null end) HFCol_Feb
  , max(case when month(dBDate) = 2 then  HVCol else null end) HVCol_Feb
  --- etc for the other month
 from tbl1 
group by UPDATEDATETIME
