Hi,
This is my first experinece in writing to u. Please excuse any obvious errors.
I have only recently started using the postgres database and i would like to know if
it is possible to return a record from the fucntion(both sql and plpgsql).
I tried this code.. but the reuslt i got was
create function ret_rec(char(10)) returns setof label as
'
select * from label where label_id = $1'
language 'sql';
hmv=# select ret_rec('L0001');
?column?
-----------
136449928
I also tried this..
create function ret_rec(char(10)) returns label as
'
declare
label_rec record;
begin
select into label_rec * from label where label_id = $1;
return label_rec;
end;'
language 'plpgsql';
hmv=# select ret_rec('L0001');
ret_rec
-----------
136469400
(1 row)
What is the problem and what is this value that is being returned? Is there any other
way in which i can handle this?
Please help.
Also, please tell me if there is any way in which i can pass values to a plpgsql
function that is being called by a trigger?(ie) this function exceutes when a trigger
fires.. can i pass arguments to this function?
Regards and Thanx in advance
Deepa.
