Thread: crosstab help
I have a simple table
item_number week_of planned_qoh
------------------ ------------------ ------------------
00005 2012-02-05 30
00005 2012-02-12 40
00005 2012-02-19 50
where
item_number text
week_of date
planned_qoh integer
I have a function that returns the table as above:
chromasun._chromasun_totals(now()::date)
I want to see
00005 2012-02-05 2012-02-12 2012-02-19 30 40 50
This is what I have tried (although, I have tired many others)
select * from crosstab('select item_number::text as row_name,
to_char(week_of,''MM-DD-YY'') as bucket, planned_qoh::integer as buckvalue
from xchromasun._chromasun_totals(now()::date)')
as ct(item_number text, week_of date, planned_qoh integer)
I get
ERROR: return and sql tuple descriptions are incompatible
What am I doing wrong?

Hi,
the return type of the crosstab must be defined correctly, according to the number of expected columns.
Try following (untested):
select * from crosstab(
'select item_number::text as row_name, to_char(week_of,''MM-DD-YY'')::date as bucket, planned_qoh::integer as buckvalue
fromxchromasun._chromasun_totals(now()::date)')
as ct(item_number text, week_of_1 date, week_of_2 date, week_of_3 date)
Regards,
Andreas

That worked! However, I need the actual date to be the column heading? And
of course the dates change depending on the date passed to the function:
xchromasun._chromasun_totals(now()::date)
So how do I get the actual dates as the column header?

As far as I know you must define the numbers (and types) of columns and column headers individually for each query or
definesome custom function...

Hello all ,
I have a similar situation - an EAV table.
entity_attr_id integer entity_id bigint ent_attr_value character varying
I am trying
select * from crosstab('select entity_id::text as row_name,
entity_attr_id::bigint as entity_attr_id , ent_attr_value::text as
ent_attr_value from org_entity_attr_value order by 1') as ct(
row_name text,entity_attr_id bigint,ent_attr_value text )
and get an error -
ERROR: return and sql tuple descriptions are incompatible
