I am using postgres crosstab() function to create a table.
My first dynamic query function (dynamic_crosstab) creates a sql select statement containing crosstab(), and then this select statement gives the final result on execution. dynamic_crosstab functions works perfectly
I need to execute this select query (result of dynamic_crosstab function) by using parameters, so I am again using a function as follows.
cur refcursor,
text,
text,
text)
RETURNS SETOF refcursor AS
$BODY$
declare
val_1 text;
begin
select * from dynamic_crosstab($ select
p.location_id, p.employee_id, pt.description, sum(p.hours_allocated) as hours_allocated
from
preference_type pt, preference p, preference_date_etl pde, date_etl de
where
pt.id = p.preference_type_id and
pde.preference_id = p.id and
pde.corporation_id = $4 and
de.id = pde.date_etl_id and
pde.deleted = ''N'' and
p.deleted = ''N'' and
pt.deleted = ''N'' and
de.local_date between ''$2'' and ''$3'' and
p.employee_id IN (
select id from employee where user_id IN ( select id from app_user where corporation_id =||$4||))
group by p.location_id, p.employee_id, pt.description $,
$ select distinct description from preference_type where deleted =''N'' and corporation_id=$ || $4,
'text','location_id int , employee_id int',false) into val_1;
open cur for execute val_1;
return next cur;
end;
$BODY$
Now this function should execute the crosstab() function and it does when I use deleted= 'N' in the second parameter but shows error because crosstab() needs deleted=''N'' to execute.
And I need to use deleted=''N'' to get my results but postgres treats my second parameter as a individual query when I try to do it.
The first parameter is passed perfectly with deleted =''N'' but postgres does not recognize second parameter when deleted=''N''.
Please suggest what modifications I should do to make this work.
Thanks.
