Hi, I don't know if it because I'm as sick as dog or I'm just a plain idiot - most likely a little of both. Here is my table week_of date, item_number text, planned_demand integer. I have week_of item_number planned 2012-02-12 00005 200 2012-02-19 00005 -30 2012-02-26 00005 -16 I want to see item_number 2012-02-12 2012-02-19 2012-02-26 00005 200 -30 -16 I actually have added fields but that should get me started. Thanks for help from an old man with a very bad cold. Johnf

select *
from crosstab('select item_number::text, week_of::date, planned_demand::text
from holding_table order by 1,2')
as ct(row_name text, week_of date, planned text)
The above does not work. What am I doing wrong?
